Cone crusherapply to crush the medium-hardness of various rocks and minerals. Simple structure, high production efficiency, easy adjustment, the use of economic and other characters. Patterns of broken cavity are decided by ores use. the standard type (PYB) apply in medium fine; medium (PYZ) apply in the medium-fine crush short-head (PYD) applicable to the fine crush.Working principle of cone crusher:
When the cone crusher is working, the motor drives the eccentric bearing busing via spring coupling, transmission shaft and a couple of cone gear wheel. The crushing cone axis is forced to wing by the eccentric bearing bushing, which makes the mantle sometimes close to the bowl linear, and sometimes far away from the bowl linear. The raw materials are pressed, impacted and finally crushed in the crushing chamber.Features of Cone Crusher:1. larger capacity achieved by the design of larger crush throw2. setting of discharge opening is hydraulic drive3. grease seal reduces dust contamination effectively4. cavities of standard or short head are chargeable through different mantles and bowl liners5. hydraulic overload protection device helps to remove tramp iron and reduce downtime6. thin oil lubrication station is outfitted with air-conditioning cooling system for better cooling performance

In all rare metals, the importance and scarcity of chrome ore and scarce are most obvious, which is at the top of "strategic metals". The chrome ore is mainly used in the production of stainless steel and various kinds of alloy steel in the form of ferroalloy (such as ferrochrome), which has the advantages of strong hardness, wear-resisting, heat-resisting and corrosion resistance.
At present, the common chrome extraction processes mainly include gravity separation, magnetic separation, electric separation, flotation, gravity-magnetic separation process. Below, let's take you to learn about each chromite ore processing process.
From the point of production practice, the gravity separation is still the main chrome extraction method in the world method now, which uses the loose stratification in the water medium. At present, the gravity separator used in the chromite ore processing includes the shaker table, jig, spiral chute and centrifugal separator.
It is worth noting that stage grinding and gravity separator, or the combination of various gravity separators can be used according to the chrome ore properties, thus further improving the grade and recovery of chrome concentrate.
Because the chromite has a weak magnetism, we can use the strong magnetic separator for chrome extraction. There are mainly the following two cases: one is in the weak magnetic field, remove the ore in the strong magnetic separation of minerals (main magnetite), improve the ratio of ferrochrome. Another is to separate the gangue minerals and recover chrome ore (weakly magnetic mineral) under the strong magnetic field. If necessary, the weak magnetic - strong magnetic separation process can also be used to effectively separate the ore and achieve the chrome extraction.
The electric concentration process is mainly used to separate chromium ore from silicate gangue by using the difference of electrical properties of minerals, such as conductivity, dielectric constant, etc. For the chrome ore, a few chrome can be used directly by the electrical concentration, most of them only use the electrical concentration process in the concentration process. The concentration process has a special effect on removing silicate minerals (such as quartz, etc.) from chrome. Therefore, after the separation of chrome, another stage of the electric concentration process can be added for cleaning, which not only further improves the grade of chrome concentrate, but also greatly reduces the content of silicon dioxide.
At present, we can use the flotation process to recover the chromite with fine grain size (-100um) after the gravity separation. The results show that Mg2+ and Ca2+ can inhibit the chromium ore, and the inhibition of Mg2+ is influenced by the type of anions in the slurry. Therefore, after knowing the cationic behavior in the pulp, we can choose the appropriate pulp PH value, reagents concentration, add the order of inhibitors and activators, achieve the separation of chromite and pyrite.
Sometimes, the single gravity separation method cannot recover the chrome concentrate effectively. At this time, the concentrate obtained by the gravity separation can be separated by weak magnetic separation or strong magnetic separation, further improving the grade of chrome concentrate and chromic oxide-ferrous oxide ratio.
For example, the 100-10mm grade of raw ore adopts two-stage dense media separation. The medium ore of the dense media separator is crushed to 10-0mm and then merged with the 10-0mm grade of raw ore for separation. The grades of 10-3mm and 3-0mm are sent to the jigging process. After the middling of the jigging process is ground to 0.5-0mm, the spiral concentrator is used for separation, and the shaker table is used for the separation of mineral mud (0.5-0mm). Then, the high-field magnetic separator is used to recover 0.25mm slime separated from the tailings of the shaker table and spiral separator, ensuring the content of chromium oxide in the concentrate and reduce the loss of valuable components in the tailings.
Here are the common five chrome extraction processes. For the rich ore with high chromium oxide content, single gravity separation or magnetic separation process can be adopted. For the chrome with low chromium oxide content, the combined process of gravity separation and magnetic separation usually gets a better index than the single process. Of course, the specific chrome extraction process should be determined comprehensively according to the nature of the chrome ore, the actual situation of the chromite ore processing plant, the investment budget, so as to ensure the ideal beneficiation benefits and economic benefits.
India is abundant with stone resources that include granite, marble, sandstone, limestone, slate, and quartzite etc. Stone crushing industry has long history and plays important role in economy development in India.
In stone processing operation, stone products generally are loosened by drilling and blasting and thenconveyedtothe processing operations. Techniques used for extraction vary with the nature and location of thestone deposit. Processing operations may include crushing, screening, size classification, materialhandling and storage operations.
Crushing is the first and integral step in stone processing operation. Stone crushing operation is generally processed in three stages: primary crushing, secondary crushing and tertiary crushing. Each crushing stage involves different types of stone crusher and produces different particle sizes. Stone crusher plant prices are different according to different types and production capacity.
The feeder or screens separate largeboulders from finer rocks that do not require primary crushing, thus reducing the load to theprimary crusher.The stone that is too large to pass through the top deck ofthe scalping screen is processed in the secondary crusher. Cone crushers are commonly used forsecondary crushing. Tertiary crushing is usually performed using cone crushers or other types of impactcrushers.
With the development of mining industry and mining technology, various types of high performance stone crusher plant has been developed. Selection of a crusher for stone crushing production depends on source stone properties such as fragmentation pattern and hardness and the scenario to which the end product will be applied.

Two types of stone crusher plants in India have proven capable of producing high quality manufactured sand for concrete and asphalt, VSI crusher and new generation high speed cone crushers. SBM developed leading technology in both crusher types through VSI crusher and HP cone crushers.
Small scale crushing is an integral part in stone crushing industry in India. It makes great contribution to economy development. Stone crushers are primarily small scale industries mostly owned and operated by less educated individuals and are scattered all over the country. For small stone crushing operation, with the restriction of low investment cost, they can afford large new crushing equipment, and prefer small crushing machine, such as small jaw crusher, mini impact crusher and small cone crusher.
Small cone crusher plant cost is relatively cheap, it is usually applied in fine crushing operations for aggregates production, quarrying, mining, minerals processing, construction and recyclingoperations. Theproduction capacity ranges from 10 to 100 TPH. SBM customize large or small crushing solution according to your requirements. Please contact us for more information.
