1. The investment in mainframe and supporting auxiliary equipment for gyratory crusher and civil engineering is large, but the operating cost is low, so it is suitable for the condition of long service life and long annual crushing operation time.
2. Select the processing capacity of the gyratory crusher. The single machine should not be less than 1500t/h.
3. Due to the small amount of gyratory fracture, the main castings or forgings are large, and the technical requirements are high, so the processing and manufacturing cycle is long. When choosing gyratory crusher, you should consider how to control the quality of the product to ensure that there is no potential risk for the installation and operation of the equipment after delivery.
4. When the rock is hard rock and highly abrasive rock, it may be considered to choose gyratory crusher for primary crushing.
5. When selecting gyratory crusher for primary crushing, due to the large single-line production capacity, it is necessary to consider whether the shipping equipment is complete. Compared with mining projects, the shipping equipment of hydropower projects is generally relatively small, so you should make comprehensive technical and economic comparison of mining and shipping equipment.
6. The design of the hopper car receiving bin should consider the size of the dump truck and optimize the design. The effective living volume of the general bin should not be less than the load capacity of 3 cars.
When the above analysis shows that it is not appropriate to use gyratory crusher for primary crushing, you can choose jaw crusher or primary impact crusher for primary crushing.
