With the increasing use of natural sand resources for concrete, the huge waste pile has become a difficult problem for aggregate producers. Aggregate industry is an urgent need for sand production made by vertical shaft impact crusher to deal with this challenge.
Aggregate prices, sales and production technology, has been a hot topic of quarry managers, there is the proportion of products. As part of the broken aggregate production process, up to 30% (rocky) of the material is broken into less than 4 mm of particles and thus can not be used as coarse aggregate.
For the operator, the grain level of the symbiotic material is the most unfavorable, not only difficult to find a way, or even difficult to deal with. Therefore, in many quarries, you can see this huge "waste" pile, not only affect the profitability, but also lead to environmental problems.
On the other hand, over the past few decades, concrete in many densely populated areas of the world has been depleted with natural sand resources. Therefore, the need to find alternative materials. The waste material produced by the broken material is large and the physical properties are suitable. It is expected that the future will be the best substitute for natural sand.
