This is first determined according to the properties and hardness of the granite rock. Granite is a rock with high hardness, which is difficult to crush and wears a lot to the crusher. Therefore, a reasonable crushing plan is very critical for post-production.
Generally, the primary crusher still needs to use the jaw crusher, which can crush the granite to 10-30cm.
Next, the choice of secondary crusher is different. For hard rocks such as granite, cone crusher is a more suitable choice. Currently, spring cone crusher and hydraulic cone crusher are commonly used. According to different cavity types, short head type and standard cone crusher single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher are used together. In this way, although the initial investment is higher, the operating cost in the later stage will be much lower, avoiding the normal operation of production due to frequent replacement of parts and maintenance.
The cone crusher can produce 5-10/10-15/15-20/20-31.5 and other different specifications of stone materials.
If you want to produce mechanism sand in one line at the same time, you can add a sand making machine after the cone crusher to produce mechanism sand of 0-5mm.
The middle is supplemented by feeder, vibrating screen, belt conveyor, sand washing machine and other supporting equipment.
This is a relatively complete granite crushing production plan, and the actual production situation can increase or decrease equipment.
