LIMING VU aggregate optimization system
advantages
traditional aggregate making
Problems
1.Good Particle Shape

The output shape can rival natural sand (Real product rate can be 58%-59%).

2.36~4.75mm
1.18~2.36mm
0.6~1.18mm
2.Low Consuming Cost

New innovated technology combines performance and technology of equipment reasonably, realizes low consuming cost.

3.Adjustable Fineness

The fineness is adjustable easily (2.2-3.2).

4.Precise Grading

The grading is more precise than before. By using water mixing machine wet sand can be produced.

5.Dust-proof and Environmental

Full enclosed structure prevents the dust from leaking out. With no noise nor pollutant discharge, the dust-proof is absolutely of no risk at all.

1.Coarse shape, high cost

Due to the use of cheap production of the jaw crusher, simple crushing, single screening, it makes the needle flake of coarse aggregate particles, high void ratio, the quality fluctuation significantly, which leads to a big dosage of cement mixed by concrete, higher cost.

2.36~4.75mm
1.18~2.36mm
0.6~1.18mm
2.Unstable quality, low capacity

After several years exploitation, the source in the river is reduced and in short supply. Then the price rises but no guarantee on the quality and supplying, Which makes the laboratory often adjust the mixing proportion, causing a big dosage of cement mixed by concrete, seriously dragging on the enterprise's production and cost.

3.The disadvantage of existing technology

The existing technologies such as the simple crushing, the single screening, and the water dedusting have caused disqualification of the final sand. And also it is very hard to deal with the wastewater treatment.

4.The serious pollution of noise and dust.

With the more and more strict requirement of the environmental protection, a lot of factories which do not meet the requirement have been shut down by the government.

The VU aggregate optimization system of Liming
Emerges as the times require

In china, the need of sand is over 10 billion tons and the total value of sand industry is more than 500 billion Yuan. But there are many limits of the existing sand industry such as the keep increasing price, the high transportation cost, the uneven quality and the shortness of the natural sand while the lower quality, the excessive trash, the bad shape of the machine-made sand. Therefore, to meet the requirement of the wide market and to make up the disadvantage of the traditional technology , the VU aggregate optimization system of Liming Heavy Industry have emerged as the times require. This optimization system adopts the advanced technologies and scientific payoffs from domestic and abroad which will provide a brand new dry sand-making solution to the problem of exiting sand-making industry and will bring a new developmental chance for sand-making, cement-making, dry blend and ready-mixed concrete making industry.
Taking the cheap and easy to get tailing, waste, construction waste, aggregate chips, and the small pebbles as the raw materials, the VU optimization system can produce the machine-made sand just like the natural sand with the dry environmental technology. The sand produced by the VU optimization widely used as the auxiliary sand of mixing plant, dry concrete, cement, aggregate quarry, and large –scale construction which can meet the huge needs of the sand market. With the enormous value of investment, the VU optimization system has been approved and welcomed by the customers.

Analysis on Technology

  Liming VU sand aggregate gradation graph

It is generally accepted that 2-area medium size sand is the better choice for making concrete because of its good shape and appropriate size. To the contrary, due to the large content of coarse sand and sand powder and small quantity of fine sand, the normal machine-making sand can not meet the standard of the 2-area medium size sand. When using it to make the concrete, it will lead to large quantity of cement paste and poor peaceability.
Liming VU gravel aggregate system can well control the sand gradation curve in grading area 2. When compounding concrete with the same cement, the production mechanism of Liming VU gravel aggregate system could help you with a higher strength which greatly meet the sand requirements on various kinds of concrete and dry-mixed mortar.

Liming VU dry process of sand and gravel aggregate system with the most reasonable, greatest degree reproduce naturally in the process of natural sand formed broken, erosion action such as friction, natural washing, make product sand performance is improved. - 15 mm raw materials (can be stone chips, pea stone and other cheap accessible raw materials such as stone) after dealing with the VU system is reasonable and efficient, reasonable distribution, grain output fruity, controllable sand powder content, as well as dry clean, can undertake unity recycled high value-added powder (determined according to the raw material can be used).
