process design of granite crushing plant

  • The hardness of granite is higher, but it is brittle. Compared with basalt, granite is easier to be broken; compared with limestone and other medium hardness materials, granite is more difficult to be broken. Therefore, in the process design of granite crushing plant, the crushing equipment based on lamination principle should be selected as far as possible to reduce the loss of wear-resistant parts. For medium and short-term projects, two-stage crushing can be adopted; for medium and long-term projects, three-stage crushing is an ideal choice.

    If the customer has higher requirements for the final stone particle size, a set of impact crusher can be configured to form a three-stage crushing process configuration. The investment cost of three-stage crushing is high, but for the long-term operation of the gravel plant, the production cost reduced by the three-stage crushing is very considerable.

    For small and medium-sized granite crushing plant, the process configuration of jaw crushing and impact crusher can be adopted. The size of granite will be reduced as much as possible by jaw crusher, and the impact crusher will be used for shaping and crushing, so as to achieve the crushing effect of excellent grain shape, proper control of wear and low cost.

    For the high-yield granite crushing production line, the three-stage crushing process should be used as far as possible, and the process configuration of jaw crushing + fine jaw crushing (or cone crusher) + impact crusher can be adopted. The power consumption and wear cost of laminated secondary crusher are relatively low, but the investment cost is relatively high.

    The two-stage crusher can be used for the production of high-grade jaw crusher. Although the particle size is poor and the proportion of needle flake stone is high, the operation cost and investment cost can be greatly reduced. The sales price of sand and stone with poor grain shape will also be affected.
