The mining industry in Zimbabwe is a significant contributor to the country's economy. The mining industry in Zimbabwe accounts for over 60% of exports in the country. Having a terrain that is quite similar to Australia and Canada, the country is a producer of many minerals and metals. Zimbabwe is particularly known for its resources of platinum group of mineralsas well as nickel, gold, diamonds and others.
Zimbabwes mining industry is focused on a diverse range of small to medium mining operations. The most important minerals produced by Zimbabwe include gold, asbestos, chromite, coal and base metals. The mining industry contributes approximately 8% towards the countrys GDP.
The first step of the mining and mineral processing operations is to remove the mineral value in ore from the host rock or matrix. Minerals may be extracted from the earth using a variety of techniques. Most extraction processes result in the removal of ore and associated rock or matrix in bulkform from the deposit, using blasting and crushing operations to break the ore into pieces of manageable size or to separate the ore minerals from unwanted material.
Mining operation involves many different types of machines. As referred, there are many small and medium mining operations in Zimbabwe; mining technology is still in developing. It requires high technology and quality mining equipment to develop mining industry in Zimbabwe. Crusher machine is one of integral equipment in mining industry. SBM provides high performance and low price crusher for mining industry in Zimbabwe.
Different scale of mining operations has various investment capacities and requires different types of mining machines.In mining operation, crushing is the first the integral operation, the layout of mineral crushing plants is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.
There are many factors to be considered for designing a reasonable crushing plant, such as ore characteristics, mineral deposit location, climatic conditions, expected operational life, safety, environment, and operability and maintainability. There are three main steps in designing a good crushing plant: process design, equipment selection, and layout.
With the development of quarrying and mining industries, various new types of mining equipment are designed for different applications.

Zambia's economy mainly includes agriculture, mining and services sectors. Among them, mining industry takes important position. After independence to the 1970s mid time, economic has rapid development. Since then, because the international mining market prices drooped and the government nationalized policy mistakes, the economy was in trouble. After new government took the office, it pushes forward the economic privatization and diversification, actively attract foreign investment, which maintains rapid economic growth. The mining industry is relatively developed and it is one of the main pillars of the national economy. Its main body is copper and cobalt mining and smelting.
Cobalt is a hard metal with steel grey and metallic luster. Its main physical and chemical parameters are close to iron, nickel, and iron clan elements. Cobalt is a kind of high melting point and good stability of magnetic hard metal. It has permanent magnetism, melting point is 1495 , boiling point is 2900 . With high temperature resistant, the mohs hardness is 5. It is the important material to manufacturing heat resistant alloy, hard alloy, anticorrosive alloy, magnetic alloy and all kinds of cobalt salt. It is widely used in aviation, aerospace, electronics, machinery manufacturing, chemical and ceramic industries. Therefore, it is an important strategic material. Physical and chemical properties of cobalt determine it is the production of heat-resistant alloy, hard alloy, anticorrosive alloy, magnetic alloy and important raw materials of various kinds of cobalt salts.
According to the cobalt characteristics, SBM experts recommends Zambia cobalt mining operators adopting the following crushing machines: cobalt jaw crusher as the primary crushing machine, cobalt cone crusher as the secondary crushing equipment, if there is need tertiary crusher machine, the impact crusher can be used.
We can see that the cobalt hardness is 5 and it belongs to the medium hard materials. The application of cobalt needs powder materials for further production. Cobalt jaw crusher is always used as the primary crushing machines. With the jaw crusher's help, large scale cobalt materials will be processed into small size and it is designed to exceed the primary crushing needs of customers in Zambia mining, quarrying and recycling industries. These machines are amongst the most advanced and reliable in the market and are highly productive in a variety of applications. With a combination of dynamic jaw profiles and highly efficient drive system these machines return some of the lowest operating costs in their class.
The secondary cobalt crusher machine is the cone crusher. It is suitable for secondary and tertiary crushing in the Zambia cobalt mining applications. The advanced technology will provide high volumes of excellently shaped product.
Depending on customers' production requirements in Zambia, SBM designs the mobile cobalt crushing plant which includes jaw crusher, cone crusher and the feeding & screening machines for local clients.

These grinding machines are designed to meet the rugged grinding needs of the mining industry. Cobalt grinding mill contains a hydraulic motor designed to match power and for grinding applications.
Diamond, also means mineralogy diamond,it is formed by geological processes.The primary ore mainly are kimberlite and lamproite. Modern science and technology provide new ideas and methodsfor diamond exploitation and diamond formation. As we all know, diamond is the hardest gem in the world, it has thesimplest ingredients, which is composed of carbon, and a natural cubic crystal structure. Its composition is same ascoal, pencil and sugars that are closely related to us. Under the pressure (high temperatures), carbon will crystallize to form graphite (black), while under high pressures and high temperature, carbon will crystallize to form precious diamonds (white). So diamonds are very precious, and so it has very high value, and lots of people want to own them in Russia, so diamond exploitation is very important for the investors who want to gain many profits from diamond industry.
Diamond is a natural mineral that is rough diamonds. It is understood that the diamond native deposits, mostly adopt the method of combination between the open-pit mining and underground mining. On the part of earths surface, directly along the rock excavate the pit barrel, and stepped down mining drill, each step will spiral downward which is easy for truck to transport the ore out. On the other hand, when deep underground (300 meters), the first thing is to dig a well next the mineral deposit, then dig a lateral tunnel leading to the deposit, then through technical means to make internal ore be crushed, and then through a series of horizontal and vertical roadway to transport the ore out.
As for the diamond sand deposits, which can be divided into two categories: one is the ancient beach, the ancient river diamond deposits exposed above the water, it can removethe overlying sediment, then using the method of open pit mining, then sent the gravel to the concentrator, while the other deposit is located at the bottom of the modern river, known as the "wet deposit", you need to first drain the water or diverse the river, and then adopt the method of open-pit mining.
It is reported that the ore after mined first should use jaw crusher and cone crusher for crushing, sometimes also put the ore in open pit mine, and then natural weathering crushing. After the ore were crushed to 3 to 6cm,and then will remove the clay with roller washing machine.Then you can use the bouncing beneficiation method to separate coarse gravel after washing, as to the separated coarse gravel, you can have second crushing and panning separation. Or use gravity beneficiation methods, because diamond ore density is larger than other ores, so the ore contains diamonds will be discharged from the bottom of the funnel-shaped container.
After above these coarse dressing, if diamonds still cannot be completely separated, then should have further selection. In fact we can use the diamond lipophilic water-repellent properties, the ore which containing diamonds will be scattered evenly on the tapewith grease and kept turning, so make the surface of grease tostick the diamond.Then, the oil will be collected in a container which is made of fine metal sieve cloth, then put in the hot water pool, let the oil melting and then drift away. After roughing and fine selection, then manually recycle diamondby the professional technical personnel.
SBM is professional in producing crushing equipment, grinding equipment and beneficiation equipment, so we can provide you high efficiency and low cost Russia diamond crushing equipment. We believe that our machine will make a big difference in your diamond business.

The jaw crushers we offer for sale include Superior, Type B Blake, Fine-Reduction, and Dodge sizes, 4 by 6 to 84 by 66 inches. A reciprocating machine, the crushes material in a straight line between jaws without grinding or rubbing surfaces.
As you compare this jaw crusher feature for feature with other makes youll see how this modern crusher lowers principal costspower consumption; lubrication; jaw plate, toggle plate, and bearing wear youll understand why we say the crusher promises you a new low cost per ton of material crushed!
Firstthose who have rock or ore tougher and more abrasive than most material. Secondthe operators whove had difficulty with other designs of crushers. And finallythe operators who naturally buy the bestexpecting their added investment to be written off in comparatively short time through lower operating and maintenance costs!
Compare the dimensions with those of conventional jaw crushers. It measures up to 20% longer; has up to 35% deeper crushing chamber! And while you naturally expect to pay more for this bigger,deluxe crusher, it follows that you get more too! For example:
You get a crushing chamber with a full-width receiving opening increased capacity! You get an acute crushing chamber that minimizes slippage very important with hard, tough materials. You cut down crushing power required through longer pitman and front toggle. You reduce packing, get closer setting through the longer jaw, non-choking plates. You lower maintenance cost, get longer jaw plate, toggle, and bearing life through lower structural stresses, simplified design.
Frames of these crushers are built for maximum rigidity designed to prevent distortion during operation. Side members are heavy steel plate, reinforced by steel ribbing. End members are cast steel, of box section design, to provide maximum strength.
The side frames are deep-welded and then stress-relieved in thehuge annealing furnaces to eliminate possible failure adjacent to welds. The result is a uniformly strong frame that will remain true during the long service life of the crusher.
A jaw crusher frames are of sectionalized construction to facilitate handling. This design minimizes heavy lifts makes the crusher suitable for installations where parts must be passed down a shaft or through a tunnel. End members are attached between side members with vertical tongue and groove joints and held together with fitted bolts. Long-bearing surfaces prevent angular distortion.
Important differences in design show up visually when a cross-section of the crushing chamber of a conventional crusher is superimposed over that of the crusher. Now you can see the advantages of the 1 /3 deeper chamber using non-choking jaw plates. Its more acute crushing angle is carried to the very top of the chamberpermits nipping the largest material that can enter the receiving opening!
Lower plates on the swing and stationary jaws are suspended from projections on jaws. These plates also support the upper plates. This exclusive feature permits the free expansion of manganese steel jaw plates greatly minimizes the possibility of buckling or warping prevents costly shutdowns!
SWING AND STATIONARY JAWS on the jaw crusher are annealed cast steel box section construction designed for maximum rigidity. The jaw swings on a sturdy shaft that is clamped to the crusher frame. This shaft also serves as a reinforcing tie across the top of the frame. The entire design facilitates lubrication and replacement of shaft bearings.
Jaw plates are constructed of manganese steel and have corrugated crushing surfaces which reduce the power required for fracturing material. The jaw plates are built into two pieces to jaw. Those on the swing jaw are interchangeable. Plates on the stationary jaw are the non-choking type, not interchangeable. Lower plates on both jaws are suspended from jaw projections and support upper plates. The main advantage of this construction (see above) is to permit the free flow of manganese steel. All four plates are held in place by large through-bolts equipped with springs to prevent bolt breakage.
Heres still another feature youll find on the jaw crusher! Renewable wearing plates between the cast manganese steel jaw plates and swing and stationary jaws provide a firm backing for the jaw plates. If, for any reason, looseness develops in the jaw plates, these wearing plates, not the jaws, take the wear! By protecting expensive jaw castings, these wearing plates increase crusher life simplify maintenance minimize causes for shutdowns.
The heavy, two-piece corrugated manganese steel jaw plate is designed to fracture the toughest kinds of rock or ore with a minimum of power. The unobstructed clearances above, between, and below the plate sections permit free flow of manganese steel.
This construction eliminates the need for extra holding pieces, greatly minimizes the shearing of bolts. The amply designed shaft not only supports the swing jaw but reinforces the frame, serving as a tie between sides.
Notice the extra length of this jaw as compared to conventional types. Designed up to one-third longer, it exerts greater pressures in the upper portion of the crushing chamber, distributes crushing action more evenly. The result is a gradual reduction of ore to the choking point, and increased capacity!
Another, southern iron ore mining company, chose this 48 by 42-inch crusher to replace a conventional design that had failed. They explained, In our process, weve got to have a ruggedly designed crusher capable of continuous operation!
CRUSHERSin sizes from 36 by 25 to 60 by 48 inchesare giving these and other operators more for their money more capacity; more crusher life; more satisfaction! It can pay you too, to know more about this great crusher! Why not call in your use today!
All sizes of crushers feature a three-piece toggle plate construction. Worn ends may be replaced no need to discard the entire toggle. Bronze toggle ends fit into replaceable hardened steel toggle seats in swing jaw. Properly lubricated, this assembly materially reduces maintenance.
Toggle plates for these jaw crushers are of three-piece construction, consisting of an iron center section (2) to which are bolted two replaceable bronze ends (1 and 3). Toggle seats are carefully machined and equipped with protecting shields that deflect dust and dirt.
A toggle block, arranged for both vertical and horizontal adjustment, is provided at the rear of the frame. By inserting shims above the toggle block, the crushing stroke can be adjusted. Insertion of shims behind the toggle block adjusts the size of the discharge opening. Parallel alignment is assured and unnecessary strain in the crushing machine is avoided.
The pitman in any jaw crusher is essentially a tension member. However, because it also has a vertical reciprocating movement, it is desirable to keep its weight as low as possible, consistent with maintaining the required strength.
In the crusher this is accomplished by designing the pitman as a skeleton member, first to provide the necessary strength for tension and with stiffness against overturning thrust provided for by deep integral webs.
The pitman is designed with only four large-cap bolts, and the pitman cap is ribbed for proper distribution of the load to these bolts. The pitman is swung on the eccentric shaft which is supported by removable, water-cooled bearings on the frame.
The pitman is a two-piece annealed cast steel construction, with a cap designed for water cooling. Bearing surfaces on both pitman and cap are babbitted and are joined together by four large forged steel bolts. The elimination of excess bolts inherently found in conventional design results in a more uniform distribution of load.
The pitman (eccentric) shaft is heat-treated, forged steel constructionof ample diameter so that stress, even under the shock of suddenly clogged jaws, is low. The shaft is carried in removable, water-cooled, babbitted bearings designed to permit quick removal or replacement without having to strip the crusher.
Heres a typical toggle plate for jaw crushers. It is constructed in three pieceswith the center section of iron, two ends of bronze, designed for quick bolting to the center section. This unique construction materially reduces replacement and maintenance costs makes it unnecessary to discard toggles when ends alone are worn!
A critical point in the operation of large jaw crushers is the arrangement of the swing jaw and its supporting shaft. While in most crushers the jaw is pressed on the shaft and the latter swings in frame, in the jaw crusher the opposite principle is usedshaft is clamped in frame and jaw swings on the shaft!
Another point has been lubrication. In operation, the actual movement of the swing jaw is relatively small. The result is difficulty in proper lubrication of bearing surfaces. The crusher uses a special means of lubrication and in addition is designed with the new replaceable, graphite-impregnated Scor-proof bushings which greatly reduce wear on the expensive shaftssince these bushings, and not the shaft, now take the wear!
Very careful attention is required in the lubrication of heavy mechanical units like the jaw crusher. A thorough study made of existing types of lubrication systems resulted in the selection of a pair of systems that assure positive delivery of lubricant to point of maximum pressure.
The 48 by 42-inch jaw crusher and smaller sizes are force-fed by an automatic high-pressure lubricator to the swing jaw, pitman, and main bearings as illustrated in Figure 1. A motor-driven pump forces the lubricant through pressure buildup cylinders and out to distributors which dispense a precise amount to each of the points on the bearings. No oil return is provided.
The 60 by 48-inch jaw crusher and larger sizes are lubricated by a closed circuit oiling system to the pitman and main bearings, as illustrated by the solid lines in Figure 2, and by high-pressure lubrication fittings connected to the swing jaw bearings, as illustrated by the dotted lines in Figure 2. A motor-driven gear pump forces the oil through pressure-type filters and a condenser-type cooler to a distribution manifold mounted on the crusher. The oil flows through the bearings, lubricating and cooling, and back to the reservoir for recirculation. The swing jaw bearings require servicing by portable grease equipment.
The capacity of the jaw crusher is greater than that of conventional jaw crushers. One reason is its uniform-wear crushing chamber with full-width receiving opening. Another reasonits a more acute crushing angle.
Slippage is reduced packing and choking are prevented by a more even distribution of crushing action throughout the entire length of the crushing chamber. The result is a gradual reduction of material to the choking point increased capacity!
Capacities given below are approximate and are based on standard speeds, jaw motions, and jaw plates, with a feed of quarry or mine run material weighing 100 lb per cu ft crushed. Most stone and low-grade ores are considered weighing 100 lb per cu ft crushed.
The table is based on continuous feeding. Reserve for normal interruption of feeding should be provided. A heavy-duty apron feeder is recommended for most installations, particularly where large cars or trucks are used in the quarry or mine.
When feed to crushers is scalped over grizzlies or screens the number of rejections, or material that will have to be crushed should be determined in establishing the tonnage to be handled by the crusher. The number of fines received from mine or quarry will vary widely depending on each application and should be taken into consideration in determining the overall capacity.
Whatever equipment you operate, you can be certain of careful, considerate handling of orders for repair or replacement parts. In most cases parts are shipped directly from stockyoure assured of fast delivery. The view at left shows a small portion of crushing, cement, and mining equipment parts normally carries.
Repair parts temporarily depleted or not carried in stock will be furnished in time to meet requirements whenever possible. Anticipation of future needs, placing orders in advance, will greatly aid in avoiding unforeseen delays. Genuine parts are exact duplicates or improvements of original components of your machinery, not makeshift substitutes.
