Bluestone Process Flow

People who have a deep understanding of the sand and gravel market know that the road sand is quite different from building sand. Bluestone is an important raw material for road sand. Through processing of stone crusher, the natural bluestone is crushed into final products with small particle size and high degree of adhesion. After water pouring, the gap between the sand becomes smaller, so the crushed sand is suitable for roadbed use.
First stage
The heavy hammer crusher can directly crush the materials with 600-1200 mm into 25 mm or less. After being fed into the heavy hammer crusher by the feeder, the bluestone raw material is crushed through striking, impacting and shearing action of the high-speed hammers. The lower part of the rotor is equipped with sieve plate. The crushed materials with particle size smaller than mesh will be discharged from the sieve plate while the coarse materials with particle size larger than mesh will stay on the sieve plate for repeated impacting and grinding of the hammers until they are finally discharged through the sieve plate.
Second stage
After crushing, one part of the materials is screened out by the vibrating screen as stone aggregate, while the rest part can be processed into crushed sand according to the need. This stage requires ZSJ double rotor sand machine. After entering the inlet, the materials will suffer repeated striking of the two reversely-rotating rotors within the machine cavity. Then the qualitied materials will be discharged from the gap of grate.
Third stage
The gravel produced by the sand maker is mixed with soil, dust, etc. so there is need to clean the sand before its application in the various fields. Our company's bucket sand washer is integrated with cleaning, dehydration and classification. It completes the cleaning through action of water flow, and then the clean gravel is carried off by the impeller, finally the finished sand is poured into the trough from rotating impeller, completing the whole process of cleaning.
Fourth stage
The finished sand is transported to the silo for being transported by the vehicles to each project.
