It is also suitable for any hard brittle materials or other various kinds of minerals. Through large engineering, the small rock crusher shows that it has good application prospect in the field of mineral processing equipment.

There are many factors impacting the small rock crusher production capacity: The hardness of the material. More hard material, it is more difficult to break, and this will cause serious wear. When the machine crushes hard materials, it has slow crushing speed and the crushing capacity will be small. The humidity of materials. When the material has large moisture content, it is easy adhesion when the small rock crusher works. It is also easy to jam in the process of the material transporting, which will reduce the crushing capacity. The fineness of crushed materials. If you need the high fineness, which means the end products are very fine, the crushing capacity will be small. The composition of the material. Before crushing, it will influence the crushing capacity if the materials have much more fine powder. Because the fine powder will affect the delivery, you should separate the fine powder before crushing stage.

how to select equipment in artificial sand production line? | fote machinery

how to select equipment in artificial sand production line? | fote machinery

The production process of artificial sand can generally be divided into the following stages: stone feeding crushing sand making screening powder removal finished products. The common process flow is as follows:

The whole process involves vibrating feeder, crusher, sand making machine, vibrating screen, sand washing and dust removal equipment, etc. This article will explain the technical requirements and selection principles of the equipment one by one.

The vibrating feeder is located between the feeding silo and the crusher, which can uniformly and continuously feed block and granular materials from the silo to the crusher, and coarsely screen the materials at the same time.

The materials are sandwiched between two working faces and are crushed due to the increasing static pressure applied by the working faces, which destroys the cohesion between the particles inside the rock crystal as well as the cohesion between the rock crystals and the crystal surface.

Generally, cone crusher or impact crusher are used for medium crushing. Cone crusher is aimed at processing high-hardness materials; while impact crusher for brittle and soft materials. The hammer crusher is only suitable for crushing brittle materials with low hardness and low water content.

In short, if you need a large yield, cost-effective machine, you can choose VSI sand making machines. If you need advanced structure and perfect finished grain shape, you can choose HVI sand making machine.

The screening process is the main factor affecting the gradation of artificial sand, among which the shape and size of shaker holes and the inclination angle of the screen surface are the key parameters affecting the quality of artificial sand.

Dry sand making refers to the use of dry sand making production lines to process artificial sand aggregates. The sand produced from the sand making machine does not need to be cleaned with a sand washing machine, and the sand powder is separated by a powder separator.

The powder removal process of artificial sand is the key to control its powder content, which should not only meet the requirements of different grades of concrete, but also should have little influence on the grading.

Areas with abundant water resources are suitable for wet sand production with a spiral sand washer or wheel sand washer. At the same time, fine sand recycling and sewage recycling equipment should be equipped.

50 tph quartz rock crusher for sale | hxjq

50 tph quartz rock crusher for sale | hxjq

Quartz rocks are the second most abundant mineral in the continental crust after feldspar. Quartz rocks are very hard and always in the block-shaped. Pure quartz stone is colorless and transparent, but most of the quartz stones appear in different colors because they contain micro pigment ions or transitional elements that reduce their clarity.

Quartz jaw crusher is widely used in the quartz crushing line as the primary crushing equipment. Because it has a simple structure, reliable operation, and easy maintenance, the quartz jaw crusher is widely applied in the industrial apartment such as metallurgy, chemical engineering, building materials, electric power, and transport.

Different vulnerable parts of jaw crusher have different replacement frequency. If the jaw crusher processes the materials with small hardness such as limestone, the replacement is less frequent, but if the jaw crusher processes the materials with high hardness such as quartz, it must have a large impact on the equipment, and the replacement of vulnerable parts is more frequent. Therefore, the replacement frequency of vulnerable parts should depend on its degree of wear.

Quartz cone crusher as the common medium crushing equipment plays an important role in the quartz stone crushing line. It adopted the working principle of laminating crushing which differs from the squeezing crushing. Quartz cone crusher crushes materials by the action of materials, which can better control the crushing and shaping of the finished product.

It has a high performance of wear-resisting and shock-resisting. All the wear-resisting parts of the crusher are made of wear-resisting materials and advanced technology, which can improve the wear-resisting performance and prolong the service life of the machine.

The finished product has a uniform size and good particles. After processing by the quartz cone crusher, the quartz rocks with high performance can satisfy the different needs of customers. Moreover, the crusher is reliable and flexible in operation, which can create more value in the coming future.

The crusher is very environmental because it produces less dust and noise in the production process. In the working site of the quartz cone crusher, the crusher can work stable with less frequency of fault, and reduce the pollution effectively.

It is inevitable that the crusher will wear out in contact with hard stone for a long time, so the selection of wear-resisting materials and the protection of vulnerable parts are very important for crusher. Prolonging the service life of vulnerable parts is equal to prolong the service life of crushing equipment.

Movable cone (mantle) and fixed cone (concave) are the main parts that are material and easy to wear. To prolong the service life of vulnerable parts, several aspects should be managed, such as checking the bolts and nuts, frequently, choose the suitable wear-resisting materials, purchasing the crusher or vulnerable parts from the powerful and famous manufacturer, etc.

There are a lot of manufacturers producing quartz crusher, and the materials of crushers they used are different. Actually, the quality and performance of the equipment produced by large and powerful manufacturers can be guaranteed.

At present, the network is very convenient, the price of each manufacturer are very transparent, thus influencing the other manufacturers in their equipment price, then the price of the whole devices on the market will be reduced.

Although there are so many quartz stone crusher manufacturers, in some of these manufacturers just middlemen, and they don't have any equipment production workshop. They are just nominal and make money by earning profits, then the corresponding prices of these manufacturers' equipment will be high.

In order to improve the sales of quartz stone crusher, some manufacturers will engage in some promotional activities of their equipment. During the promotional activities, the price of their equipment would be much lower than the original price, which also affects the price of equipment to a certain extent.

in pit crushing and conveying systems

in pit crushing and conveying systems

Belt conveyor systems, long the standard transportation technique in soft-rock open-pit applications, are encountering growing interest in the hard-rock open-pit sector as economic factors force companies to seek an alternative to costly truck haulage. A general review of mine conveyor systems is followed by detailed analysis of the mobile and semi-mobile in-pit crushing plant essential to successful use of mine conveyors.

In the soft-rock sector, positive experience with belt conveyors was gained in lignite mine-fields in the nineteen-fifties. In Germany, for example, 103.5 km of belt conveyor line were in use by 1962, 53.3 km of which were engaged in overburden handling; roughly 50% of these belt conveyor systems had belt widths of 1200 or 2000 ram. Since the nineteen-sixties, belt conveying has continued to make great strides in soft-rock open-pit mining, becoming the most important means of transport in this sector; belt conveyor systems in current use with bucket wheel excavators achieve performances per day of up to 240000 m bank.

If the situation in hard-rock open-pit mining is compared with that outlined above, it is apparent that the belt conveyor, despite its recognized advantages as a bulk transporter, has by no means achieved the same degree of acceptance as in the soft-rock sector. However, recent cost trends call urgently for fresh consideration of all possible forms of mine transportation, including belt conveyor systems.

Many of the general features indicated above are typical of large open-pit mining operations in North America. Mines commonly handle over 100000 t of ore and waste per day, moving the material through great horizontal and vertical distances. Transportation costs constitute a very high percentage of total mining costs. According to a recent estimate, operating costs for a 108-t haul truck may represent up to 40% of the current selling price of, for example, copper. Transportation costs of this magnitude offer an obvious starting-point for cost reduction programmes.

Although truck haulage remains the most widespread method of material transportation in open-pit mining, recent advances in truck technology (e.g. larger payload capacity, electric wheels and longer drive trains) have so far failed to offset the growing economic drawbacks outlined above. Moreover, the trend towards longer hauls and greater mining depths tends to expose inherent weaknesses of the shovel/truck concept. Increased haulage distances not only result in expansion of the truck fleet to maintain previous production levels, but impose increased manpower and support equipment requirements.

There are nonetheless a number of limitations on the use of conveyor systems in the hard-rock sector, which partly explain their relatively slow acceptance in this field. Flexibility is the argument most often cited in favour of truck-based systems. Truck transport can easily be adapted to constantly changing mining faces, with less exacting demands on long-term mine-planning strategy and sore scope for tactical improvisation.

The essential task of the in-pit crusher in a belt conveyor transport system is to reduce blasted material to a conveyable size. Crushers for this purpose are almost exclusively of the low crushing ratio type (up to 1 : 10), i.e. so- called primary or pre-crushers, designed as mobile or semi-mobile units.

Further processing to end-product quality takes place centrally outside the pit. For certain applications, reduction to millable quality (crushing ratio in the range from 1 : 10 to 1 : 80) may also be carried out in-pit, dispensing with the need for further crushing.

Developments in the use of movable crushers have typically been divided into three phases: prototype operation over a number of years, followed by gradual introduction once the system philosophy has been proven, and a subsequent rapid spread to other mines.

Recent increased use of movable crushers in hard and abrasive rock applications has led to growing popularity of gyratory crushers. Roll crushers are generally used for high-throughput overburden crushing.

In 1982/83 EGAT (Electricity Generating Authority of Thailand) invited tenders for a sub-contract to remove 15 million m of overburden annually over a six-year period at its Mae Moh open-pit mine. The successful bidder was a consortium formed by Bangkok Motors and Sahakol Engineering.

Overburden is loaded on to trucks at the face and dumped into the feed bin. An apron feeder under the bin transfers the material via the feed box to the double-roll crusher. Any material passing through the apron feeder plates is caught by the spillage conveyor under the feeder and likewise led to the crusher.

In early 1983, Utah Mines Ltd. decided to modernize its copper ore mine on Vancouver Island. The costly truck fleet used for ore transport was to be replaced by a belt conveyor system combined with semi-mobile crushing plant. Cost savings in the order of 30% were anticipated for a system comprising in-pit truck haulage (truck capacity 154 t), and an in-pit semi-mobile crusher integrated with belt conveyor transport from the mine to the processing plant.
