High quality washed sand, greatly improve the application value of the material, compared to quartz sand lower cost, especially in the construction industry, more construction mobility, good quality and stability of the advantages, can be better applied in all walks of life, but also to alleviate the shortage of quality sand and gravel aggregate phenomenon, is the hot material in the past two years, widely loved by the major sand and gravel quarries. What equipment should be used to process washed sand? How to configure 300 tons per hour washed sand production line?
In the mining equipment market, bucket type sand washing machine and spiral sand washing machine can be used for sand cleaning operation, which one is better to choose? It mainly depends on the actual production needs.
1、Drum type sand washing machine. Less loss of fine sand, high washing clarity, sand and grade with the grid after cleaning, large processing capacity, simple structure, easy to use, small footprint, low cost. More suitable for small and medium-sized sand quarries selection of investment.
2、Screw type sand washing machine. The loss of fine sand is large, seems to be washed more net, reliable work, convenient operation, set dewatering, desliming, control particle size in one, sorting washing effect is good, investment cost is higher than the bucket type sand washer. It is more suitable for the purchase of large and medium-sized sand and gravel quarries.
The main equipment composition of 300 tons per hour sand washing production line is: GZD1300×4900 feeder, PE900×1200 jaw breaker, PFW1315 European impact breaker, 3YZS2460 vibrating screen, 5X1145 sand making machine, 3YZS2460 circular vibrating screen, sand washing machine, belt conveyor, etc.
Mechanical sand production line
The process flow of 300 tons per hour washed sand production line is: the stone is blasted down from the mountain, and the stone less than 750mm is sent into the vibrating feeder through the dump truck,vibrating feeder sends the stone evenly into the jaw crusher, the jaw crusher crushes the stone for a section, and the stone from the jaw crusher is around 95mm-165mm, which is sent through the The stone from the jaw crusher is around 95mm-165mm, then it is sent to Euro Impact Crusher for second stage crushing through the belt conveyor, and the material larger than 40mm is returned to the impact crusher for re-crushing through the circular vibrating screen, and the stone below 40mm is sent to the sand making machine, finally, the material is graded and screened through the circular vibrating screen, and the material larger than the finished product is returned to the sand making machine for re-crushing, and the finished product is transported to the finished product area by the belt conveyor.
The main note is that when the feed material is 40mm - 300mm, the material directly enters the European impact crusher to crush without the front section crushing, when the material is less than 40mm, it directly enters the sand making machine to crush without the front section crushing and the second section crushing.
