The choice of a crusher in mining depends on multiple factors that ensure optimal performance, efficiency, and cost-effectiveness.
1.The period of operation
For projects with long construction period and relatively concentrated amount of crushed stone, fixed joint crushing and screening equipment should be used; for projects with short construction period and relatively scattered amount of crushed stone, especially for long linear projects such as highways, mobile combined crushing and screening equipment is selected.
2.The specification of stone materials
If the size of the stone material is large, the stone jaw crusher machine can be used as the primary crushing equipment, when the stone material size is required strictly, it is necessary to select the joint crushing and screening equipment, such as the jaw crusher, cone crusher or impact crusher and hammer crusher, and is matched with screening equipment of certain size and specifications.
3.The nature of stone materials
When crushing hard or medium hard stone materials, the jaw crushing equipment should be selected as the primary crushing equipment. When crushing soft stone, the cone crusher, impact crusher or hammer crusher can be directly used.
4.Economic indicators
The prior expenditure is the necessary and prior investment to support the normal operation of machine. The expenditure is the costs of recruitment and training of related personnel, the packaging, calibration and certification of machines, etc. The price and payment methods of machine are usually considered by the enterprises with financial constraint, which are directly related to the continuity of the project. The installation cost includes the cost of reinforcing steel and concrete materials, labor and the lifting equipment.
5.Technology indicators
The reliability of use is an important factor for evaluating the technique and performance of equipment. In general, it is required that the machine can work for 1,500 to 2,000 hours continuously without any mechanical failure.
6.Compatibility of equipment
The compatibility between the equipment introduced and the features of the project. Compatibility in the machine group: the compatibility among the equipment introduced and existing devices, such as the loader, dumper, etc., and the impact on the existing devices.
7.Relationship between worker and machine
The machine must have comfortable operating conditions, wide visibility and good air conditioning and ventilation. It reflects the operability and automation of the equipment.
