What kind of crusher is used for bluestone crushing

2022-02-04

Bluestone is a relatively common sedimentary rock in nature. Its texture is not too hard. Stone crushing equipment processes it into bluestone sand, which has many uses and a wide market, so many people invest in the processing of bluestone sand. So, which crusher is better for crushing bluestone?

bluestone properties
The main component of bluestone is calcium carbonate, which has no radiation, strong wear resistance, weathering resistance, water absorption rate of not more than 0.75%, bending strength of not less than 10.0MPa, glossiness of about 60, and density of 2800kg/m³. It is a medium hardness stone. Bluestone is widely distributed in my country, and it is a very good building material after crushing and processing.

Heavy hammer crusher is used for bluestone crushing
The heavy hammer crusher is mainly used for various medium hardness stones with a compressive strength of not more than 200MPa, such as bluestone, which is more suitable for crushing with a heavy hammer. The heavy hammer crusher belongs to the principle of impact crushing, so the crushed product has a uniform particle shape, and the gap between the grate bars in the machine can change the discharge particle size. Generally, it can produce 12 stone, 13 stone, 05 stone and sand and other finished products of various specifications; Moreover, it has the advantage of one-time forming, which allows users to save configuration costs and simplify the crushing process. In the same working time, the crushing efficiency is higher, the production energy consumption is reduced, and the cost of processing bluestone by a heavy hammer crusher can be reduced by about 40%.

How does a hammer crusher break bluestone?
When the hammer crusher is in operation, the motor drives the rotor to rotate at high speed in the crushing cavity, and the bluestone is fed into the machine from the upper feeding port, and is crushed by the blow, impact, shearing and grinding of the high-speed hammer. In the lower part of the rotor, there is a sieve plate, and the bluestone sand smaller than the sieve hole size in the crushed material is discharged through the sieve plate, and the coarse-grained sand larger than the sieve hole size stays on the sieve plate and continues to be hit and ground by the hammer. Then it is discharged from the outside of the crusher through the sieve plate.
