In the gravel production line, in general, ore is crushed by the primary crushing process and the further fine crushing process. The ore crushing machines of different model numbers are adopted in different crushing processes. Fote Heavy Machinery, here, will talk about different kinds of secondary crushing machines and the methods of the selection of the proper crushing equipment with you.
The impact crusher is a common used secondary crushing machine, which is applied to crush the material with low hardness like limestone. The particle size of its final product is even. Besides, the discharging size can be adjusted. It can process the material with quite big particle size, the range of which, generally, is 0-300mm. The one-time investment of it is low.
As the same as the impact crusher, the cone crusher is a common used secondary crushing equipment, which is applied to process the material with higher hardness, such as granite, basalt, iron ore, and so on. The cone crusher is of high crushing ratio, even and quite small particle size of the final product, long service life, short replacement period, and lower operating cost.
The jaw crusher is applied to process the material with quite high hardness. The biggest advantage of it is that it is of quite low operating cost and investment cost. Therefore, in the secondary crushing process, this kind of crushing equipment is often used, which is welcomed a lot by users.
