How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity of 2.6.
The number of crushing stages necessary to reduce ore to the proper size varies with the type of ore. Hard ores like gold, iron, and molybdenum ores, may require as much as a tertiary crushing. To design a good crushing plant one has to follow these three steps: crusher selection, crusher layout and process design. 2.4 Crushers
6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed. For

In some industries, for example, iron ore or coal, where a specific product size is required (iron ore –30 + 6 mm), a careful choice of jaw settings and screen sizes is required to produce the minimum amount of fines (i.e. 6 mm) and the maximum amount of lump ore within the specified size range. For hard mineral bearing rocks such as gold
Gyradisk Cone Crusher. For finer size products (e.g., -6 mm), a special cone crusher known as the Gyradisc is commonly used. Operation is similar to the Standard Cone Head; however, breakage is mostly by attrition rather than impact. Reduction ratio is around 8:1. Feed size is limited to less than 50 mm with a nip angle between 25° and 30°.

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
This crusher represents excellent value and promises high productivity for any laboratory, field or plant application. The mechanically simple single toggle design is reliable and easy to maintain and repair. The crusher accepts samples up to 110 mm and has a very good reduction ratio with 6 mm product size. It delivers rapid and powerful
Hammer mills are versatile machines for material size reduction. Applied to ore milling applications, our hammer mills can produce flour-fine rock powder. Glass pulverizing, rock recycling, porcelain recycling, and similar material reduction projects achieve slightly variable output sizes, from powder to rice-grain sized discharge, per operator
with 4 x 6 mm lifter bars. The t a value describes the particle size distribution of the product. As with the A*b value, a lower value of t a indicates a harder ore. HOW ARE THE A, B AND TA VALUES USED? The three values show a relative ore hardness by comparing them to other ore test data, compiled in a database by JKTech, as shown in the above data. For autogenous mill or crusher design

ST/AR VSI Crusher: General Application Guidelines REMco ST/AR VSI crushers are rock-on-anvil vertical shaft crushing machines designed to operate as second, third or fourth stage crushers for processing soft to medium/hard rocks, ores or minerals that contain less than 15% abrasives (silica, alumina, and iron). Maximum feed size is 6” (150 mm
Jaw crushers are the work horse of the crushing industry for mining, construction, and demolition recycling. Mt. Baker Mining and Metals’ jaw crushers are industrial grade, continuous duty machines. They take large pieces of rock, ore, concrete, or other materials, and crush them down to smaller sizes, for further processing in a ball or

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
