The main machinery involved in the stone crushing industry is hammer crusher, screen, conveyors etc. The process involved is to feed the stone in to the hammer crushers to make it further smaller in size as required by the customer. In the hammer crusher, the stone is crushed. The crushed stone is screened to separate the produce in different sizes by the separator. The crushed stone is conveyed by the conveyors to trucks for transport to the market place or storage area.
Gravel crushing generally is carried out in one or two stages, although three-stage crushing may also be performed. The choice of crusher depends on the type and amount of material to be crushed. Jaw crusher, impact crusher, or gyratory crushers are usually used for primary reduction. The crusher product, normally 7.5 to 30 centimeters in diameter, and the undersized material are discharged onto a belt conveyor and usually are conveyed to a surge pile as coarse aggregates. Secondary and tertiary crushing process maybe applied for producing fine particle size. Cone crushers remain the most popular for fine crushing applications.
The extracted silica materials such as sand, gravel, quartz crystals, special silica stone etc, need to be crushed to reduce the size of the particles for further processing. A mobile crushing unit is placed close to the blast area for saving transportation cost and working time. Larger mines also have a stationary crushing plant.
Crushing plants are usually equipped with a primary crushing unit and a secondary crusher with a screen plant. The primary crushing machine breaks the raw material into coarse particle size. And then the crushed material is conveyed to the secondary crushing plant for further size reduction. There are many silica crushing plant manufacturers in India, SBM will be your best choice.
