Another High Quality Sand Production Line by Dry Sand-making Method in Changde, Hunan
Project Background
Project Profile
Project design--installation & commissioning
With the issue of Trail Measures of Regulating River Sand Quarrying in Hunan Province in 2012, the quarrying of natural sand has been limited continuously. Meanwhile, traditional machine-made sand production line has such problems as poor grading, big fine modulus, mixed concrete with low strength and water pollution, etc., which incur criticisms. In light of this, LONGCHENG Inc. , the local famous manufacturer of concrete aggregate, purchased from SBM the world-class dry-type sand-making system---VU Aggregate Optimization System and put it into use in the late 2015, absolutely solving the problems existing in wet-type sand-making system like big fine modulus, low yield and severe dust pollution.
Project Background
1.The current situation of natural sand in Hunan
Hunan is one of provinces having abundant natural sandstone with the high quality natural sand distributed in the Xiang River basin and Dongting Lake. However, in recent years, the lag in traditional sand production technology and the disorder of construction-use sand market led more and more unauthorized quarrying which threatened the amount of sandstone resource in Hunan and increased the quarrying cost. After the issue of Trail Measures of Regulating River Sand Quarrying in Hunan Province in 2012, the quarrying of natural sand has been limited continuously.
2.Machine-made Sand Getting Dual Momentums--Demand & Policy
Under the circumstances that natural sand gets less and less but more and more expensive, machine-made sand, as the substitute, develops fast, filling the gap of natural sand market. So far, Hunan has launched multiple policies to improve machine-made sand projects. In some areas, industrial slag, construction wastes and barren rocks are used to make sand to develop recycling economy so that the machine-made sand industry looks like a both traditional and emerging field.
3.Problems Existing in the Traditional Machine-made Sand Production
Traditional machine-made sand production used the wet-type sand-making system which controls the stone powder content through washing gumming technology. In the process of washing machine-made sand, part of the fine particles below 0.6mm would be removed with the mud, impurities and stone powder below 0.075mm. This would cause the poor grading, big fine modulus and concrete with low strength. Meanwhile, it also reduces yield, wastes resource and leads water pollution impeding clean production.
4.Dry-type Sand-making Technology Getting Favor by Enterprises
Given the heavy demand for high quality machine-made sand in Hunan and the weaknesses brought by the wet-type sand-making system, sand-making enterprises have started to search a new technology to replace it. So this time LONGCHENG.Inc. selected SBM's VU Aggregate Optimization System which uses unique dry-type sand-making technology. It avoids the problems in dry-type technology and can process the high quality machine-made sand to replace natural sand. The VU system, therefore, got the high appreciation from cooperative enterprises of Hunan.
Performance Standard
Raw material
Raw material: limestone ( tailing from stone material factories, stone chips of low value)
Feeding size: 5-15mm
Water content: <2%
Silt content: <1%
Product application: High quality sand is used to prepare concrete and mixed mortar; High quality stone powder to replace fly ash.
Final product
Fine modulus of machine-made sand:2.7±0.1
The fineness of stone powder meets the secondary standard of fly ash.
Customer Feedback
The whole VU Aggregate Optimization System production line offered by SBM is compact structurally and reasonable on design. This production line achieves maximizing productivity and minimizing operation cost. The whole production process is dustless and the redundant stone powder is recycled. The produced stone and sand has perfect grain shape. The sand grading is satisfying. So concrete preparation in the mixing plant is very stable and reduces the use of cement. The cost of production is, therefore, reduced.
