Product Details

Automatic sand stone production line/ granite crushing plant

Regarding of the detail condition, two kinds of techniques are usually adopted in producing manufactured sand, dry way and wet way. Both methods can produce high quality manufactured sand as concrete aggregate. Especially, the dry way can produce not only the manufactured sand used in SMA road surface, but also the powder used in asphalt concrete.


For the granite crushing production lines: 

30-50tph, 50-80tph, 80-120tph, 120-200tph, 200-300tph, 300-400tph, 400-500tph, we here recommend three proposals:

◆ Proposal 1: vibrating feeder +primary jaw crusher +impact crusher +vibrating screen +belt conveying system +control system 

◆ Proposal 2: vibrating feeder +primary jaw crusher +fineness jaw crusher +impact crusher(optional)+vibrating screen +belt conveying system +control system 

◆ Proposal 3: vibrating feeder +primary jaw crusher +Compound cone crusher +impact crusher(optional)+vibrating screen +belt conveying system +control system


In the above proposals, the main difference is the secondary crusher: using impact crusher (hammer crushing principle), or using fineness jaw crusher(plate pressing principle), or Compound cone crusher(plate pressing principle). 

If the local market has not request of the stone shape, users prefer to use fineness jaw crusher, or Compound cone crusher as the secondary crusher. Because for high hardness stones, the quick wear parts cost of fineness crusher/cone crusher is lower than that of impact crusher.


For jaw crusher and compound cone crusher, the working principle is plate pressing, so the percentage of stones with flaky shape, internal cracks is high. 

For impact crusher, it has the functions of crushing and shaping, can make very good cubic shape; the stone materials are mainly used for highway, water conservancy, airport, civil construction etc.  The market prices of stones made by impact crusher is higher than that by fineness jaw crusher or compound cone crusher; the quick wear parts cost of impact crusher is also high for high hardness stones.

1. Material bin.

2. Vertical shaft impact crushers.

3. Inclined vibrating screen.

4. Sand washer or powder separator.

The feature of processing

1. Because of DR series vertical shaft impact crusher self crushing principle, the shape of manufactured sand is cubic shape.

2. The rank of manufactured sand is reasonable, fineness modulus is adjustable.

3. Index of manufactured sand is accord with the standard of country, and is the high quality concrete aggregate.

The sand making production line produced by our company can provide you with all-around technical support. The whole line consists of vibrating feeder, jaw crusher, Vertical Shaft Impact Crusher, vibrating screen and belt conveyor. According to specific requirements, we can combine different models together to meet various needs.
