The industrial used sand and gravel typically are mined from open pits of naturally occurring quartz which is rich with sand and sandstone. Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The gravel crushing plant process includes jaw crusher, cone crusher, impact crusher, vibrating feeder, belt conveyor and vibrating screen etc.
The above mentioned gravel crushing plant process cooperates with each other to complete the whole crushing process. Raw materials will be taken into jaw crusher evenly through vibrating feeder. Then belt conveyor will take the crushed materials into cone crusher or impact crusher for further crushing. Vibrating screen is used to separate the unsuitable size materials which will be taken back to crusher to be crushed again through belt conveyor.
Customers found that Zenith gravel crushing plant is a relatively low capital investment and has low wear costs. Correct selection of operating speed together with the advanced equipment, gives the operator the ability to control the production of fines.
In today's competitive aggregate market, many plants are faced with fluctuating demands for different types of gravel, with increasingly stringent specifications being imposed.
Zenith uses a unique rock-on-rock crushing process. This crushing action grinds and mills the feed material to produce a high quality product with no contamination from wear parts. As the material fed into the grinds and impacts against itself, the typical wear cost per ton of material processed is very low.
