Information
Quartz sand is a non-metallic mineral. It is a hard, wear-resistant and chemically stable silicate mineral. Take quartz stone plate as an example: it has the characteristics of no scraping, no pollution, no use. Quartz sand is widely used in glass, abrasives, casting, filter materials, construction, sheet, fireproof materials, etc.
Screening purpose
One is coarse sieve classification, and the other is fine sieve multi-layer classification.
Quartz sand classification process
First, the stone material is initially crushed by a coarse crusher. Then, the coarse material produced is transported by a belt conveyor to a fine crusher for further crushing. The finely crushed stone material enters the vibrating sieve and separates two kinds of stones，to satisfy the sand making machine. The grain size of the stone is sand, and the other part is returned to the finecrusher. A part of the stone from the sand machine is made into sand, which is washed by a sand washing machine to make a finished sand, and another part of the sand machine is broken again.
The production line has high degree of automation, low operating cost, high breaking rate, energy saving, large output, less pollution, simple maintenance, and the produced mechanism sand meets national standards, and the product has uniform particle size and good granular shape.
Effective analysis of customer needs
Quartz sand multi-layer classification, different particle sizes have different uses, water content less than 7%, non-stick material, any dry material screening. The finished crude material generally has 4 mesh, 8 mesh, 16 mesh, 30 mesh, 50 mesh, 80 mesh, 100 mesh, and 140 mesh. The screening accuracy is >90%, and the same specifications are required to be even and uniform, without large particles and fine powder.
At present, due to the efficiency of the sand making machine, the quartz stone plate line use sand making machine of 100t/h, and the finished product only accounts for 20-30%. This requires a large capacityprobability sieve to complete, and the probability sieve single equipment is 3-5 times of the ordinary vibrating screen.
Quartz sand screening equipment features
The design of the screen machine is exquisite and easy to assemble. The screen machine can be operated by one person. The sieve beam and the screen box are made of high-strength bolts. Simple structure and convenient quick maintenance.
Unique screen structure design, convenient and quick replacement of the screen (only 3 to 5 minutes), in addition to this design allows the use of a variety of screens (nylon, pp net, etc.);
The mother net fully supports the fine mesh, so the fine mesh can have a long life, and it can reduce the use of fine mesh consumables, and it can reduce many costs in the long-term production process.
Adopting small amplitude, high frequency and large dip angle structure, the machine has high screening efficiency, large processing capacity, long service life, low power consumption and low noise.
Cases
Pingdingshan Quartz Plate Line Material:quartz sand Capacity:10-100t/h Mesh size:4-140mesh Before the use of ordinary straight screen, a single unit processing capacity per hour a few tons, far from the screening requirements, not enough for the sand machine processing capacity. We designed 4 mesh -16 mesh for the customer to use the probability sieve to carry on the classification the remaining small part finished product to carry on the subdivision with the straight line screen, has saved the equipment investment at the same time has achieved the enhancement screening efficiency. ...
Probability screen is a kind of sieve machinery which can make use of the principle of probabilistic screening. The sieve theory points out that, the stranded time of each object in its interior is opposite to its weight in the work. Through the actual experiment, particle size is much smaller than the hole diameter, it can quickly pass the screen surface, the more close to the hole diameter, the longer the stranded time, if the diameter of the two sides are close, the stranded time of the material is the longest, popular speaking, large particles stay time is long , small particles stay time is short.
