Nigeria is rich in granite resources. Granite is an excellent raw material for sand and gravel aggregate and the preferred raw material for high-grade stones. Granite Stone Crusher In Nigeria are many types, mainly including vibrating feeder, jaw crusher, cone crusher, impact crusher, circular vibrating screen, belt conveyor, etc.
Granite has high hardness, but has certain brittleness. Compared with basalt, granite is easy to be broken; Compared with medium hardness materials such as limestone, granite is difficult to break. Therefore, in the process design of granite crushing production line, the crushing equipment with lamination principle shall 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 high requirements for the final stone particle shape, one impact breaker or impact crusher can be configured for integer crushing to form a three-stage crushing process configuration. The investment cost of three-stage crushing is high, but for the sand and gravel plant in long-term operation, the production cost reduced by three-stage crushing is very considerable.
For the granite crushing production line with medium and small output, the process configuration of jaw breaking + impact crusher can be adopted. Jaw crusher shall reduce the particle size of granite as much as possible, and the impact crusher shall carry out integral crushing, so as to achieve the crushing effect of excellent particle size, appropriate control of wear and low cost.
For the granite crushing production line with low grain type requirements, the process configuration of two-stage jaw crusher can be adopted. Although the particle size is poor and the proportion of needle flake stone is high, it can greatly reduce the operation cost and investment cost. The sales price of sand and stone with poor grain size will also be affected to a certain extent.
For the granite crushing production line with large output, the three-stage crushing process shall be used as far as possible, and the process configuration of jaw breaking + fine jaw breaking (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.
Performance characteristics of stone crushing production line
1. With a high degree of automation, the complete production line hardly needs manual operation except for the startup, shutdown and daily maintenance of the equipment.
2. With high production efficiency, low operation cost, large output and high income, the finished stone has uniform particle size and good particle shape, which meets the national requirements for high-speed materials.
3. Due to the reasonable matching of gravel equipment at all levels and the rigorous spatial cross layout, it has the characteristics of small floor area, high investment economic benefit, good gravel quality and low stone powder output rate.
4. Reliable operation, convenient operation, high efficiency and energy saving.
