Highest standard of sand production(core feature)

Excellent graduation, shaped-size and sediment percentage, stable and adjustable performance.

Environmentally friendly

Washing sand device is not necessary. No polluted waste and dust. Land saving concern.

Raw materials in low cost

It can be produced by "stone pieces" and seeds-shaped waste, and other low-cost materials

Low operating cost

Considerate and optimized production line concerning on the sand production ratio, labour force, electrical waste, spare parts, stability, etc.

VU system processes the raw material, like tailings, rubbish and construction waste, with the dry method, which is controllable and environment friendly. The final products is comparable to the natural sand, which can meet the following requirements.

1. Sand making for concrete batching plant and dry-mixed mortar

a. Operation is similar with the previous batching plant

b. Own-produce and own-use assure the good-quality sand providing, optimizing the concrete mixing proportion.

c. Increase the interests

2. Sand making for the mining chips

a.Processing the chips (large amount and lower sales ) from the mining processing. 

b.Enrich the final products, meet the downstream customers` needs for all kinds of aggregate.

The comparison between dry-processing and wet-processing conception

Drying-processing conception is far more advanced than traditional wet-processing methods in terms of sand performance, environmental concern, investment value and so on. Throughout a series of creative improvements, Kefid VU system provides one-time solution for all the technical difficulties and achieve the advanced dry-processing methods on sand production.
