Andesite is a magmatic rock. Magmatic rocks are formed by magma erupting from the surface or intruding into the crust and cooling and solidifying. It has obvious mineral crystal particles or pores, accounting for about 65% of the total volume and 95% of the total mass of the earth's crust. Magma is a high-temperature, hot, viscous, and volatile silicate melt produced in the deep crust or upper mantle. It is the parent of various magmatic rocks and magmatic deposits.

 

 

Andesite is similar to basalt, but its hardness and wear resistance are much higher than basalt, even higher than granite. Andesite is dense, fine, and not easy to cut. If it is cut with granite or basalt saw blades, the effect is not good.

 

We can choose stone-crushing equipment according to the hardness of the stone. Let's introduce our andesite crushing case in Indonesia.

 

 

 

For the 300tph production capacity, the C110 European version jaw crusher is used for coarse crushing. The European version jaw crusher adopts an optimized crushing chamber design and a large crushing ratio. It can efficiently crush large materials such as andesite and crush them to the required particle size range. It adopts mature crushing manufacturing technology, selects highly wear-resistant and compressive materials, and uses digital component processing equipment to make the internal structure precise and improve production efficiency. It is estimated that the energy saving of a single machine can reach 15% to 30%, and the energy saving of the system is more than doubled.

 

The medium crushing equipment uses HP300 cone crusher. The hydraulic cone crusher combines high speed and stroke, which greatly improves the rated power and throughput, has a larger crushing ratio, and higher production efficiency. This enables it to complete the crushing task more effectively when processing hard materials such as andesite.

 

 

1. Vibrating feeder: ensure that the material enters the crushing equipment evenly and continuously.

 

2. Jaw crusher: as coarse crushing equipment, it is responsible for crushing large pieces of andesite into smaller particle sizes.

 

3. Cone crusher: performs medium crushing to ensure that the material particle size is uniform and meets the subsequent crushing requirements.

 

4. Circular vibrating screen: performs screening operations to separate finished sand and materials that need to be returned.

 

5. Belt conveyor: connects various crushing equipment and screening equipment to achieve continuous transportation of materials.
