Which crushers are recommended for pebble crushing, and what equipment is needed for the whole crushing production line from pebbles to mechanism sand. Firstly, the characteristics of pebbles, such as high hardness and wear resistance, which is important for the choice of crushing equipment.
Cobblestone is a kind of natural stone with high hardness (Mohs hardness 7-8) and strong wear resistance, which is used for sand making needs to choose the crusher suitable for its characteristics.
Different crushing stages need crusher. Coarse crushing is usually done with a jaw crusher because it handles large materials well. Medium and fine crushing may need fine crushing jaw crusher, sand making stage, roll sand making machine is more suitable, roll sand making machine roll skin wear-resistant, high efficiency, finished product grain size is good. Screening equipment is also necessary to ensure that the particle size meets the requirements. There are also sand washing machines.
1.Cobblestone crushing and sand making Coarse crushing equipment: jaw crusher
Role: crushing large pebbles to medium particle size.
Recommended Reason:
Simple structure, strong processing capacity, suitable for high hardness materials.
It can adjust the size of discharged material and prepare for the subsequent medium and fine crushing.
2.Cobblestone crushing and sand making Medium and fine crushing equipment: fine jaw crusher
Function: further crush the pebbles after coarse crushing to ≤30mm size.
Recommended reason:
Simple structure, strong processing capacity, suitable for high hardness materials.
Adjustable discharging granularity, ready for subsequent sand making.
3. Sand making equipment: roller sand making machine
Role: Process the stone material after medium and fine crushing into 0-5mm mechanism sand, optimise the grain shape.
Recommended reason:
Adjustable particle size, no wearing parts, long wear-resistant roller skin.
Adjustable fineness modulus to meet different standards (such as construction sand, concrete sand).
