Fine sand recovery and grading unit with hydrocyclone

Fine sand recovery and grading unit with hydrocyclone     :

1.Simple structure

2.Plyurethane screen

3.Max 90% recycle fine material

The sand recovery units with hydrociclones are planned and carried-out for the washing, screening, drying and grading of the sand present in the dirty water, forming during the aggregates washing process.

Why the fine sand need recycling?

The status of artificial sand washing at present, most of the existing artificial sand production lines are utilizing wet production process. No matter what the type of sand washing machine is, the biggest drawback is that the fine sand (particle diameter is between 0.045mm and 1.6mm) will be in a serious loss and sometimes the loss will be over 20%. This drawback will not only reduce the output, but also affect sand gradation. For this reason, the gradation is not reasonable and fineness modulus is larger so that the product quality of mechanism sand will be largely reduced.

Working principle of fine sand recovery machine:

1. Fine sand recycling machine structure: consists of electrical machine, slurry pump, hydro cyclone, ZKR line vibrating screen, purge tank and material returning bin, etc.

2.Working process of fine sand recycling device : the sand and water mixture is sent to hydro cyclone. After centrifugal grading enrichment, the fine sand is sent to vibrating screen by sand sinking mouth. After dehydration by vibrating screen, the fine sand is efficiently separated from water and a few of fine sand and clay come through material returning bin then come back to purge tank. When liquid surface in the purge tank is high, the discharge hole can adjust the liquid surface. The weight concentration of recycling materials in line vibrating screen is 70%-85%. Adjusting fineness modulus can be realized by changing pump rotation speed, changing pulp consistency, adjusting overflow water and changing sand sinking mouth. By the process above, the fine sand recovery system can finish three functions, cleaning, dehydration and grading.

Features and benefits:

1.The traditional wet-way sand manufacturing program adopts auger-type sand washer has the problem of sand erosion, which resuilts in low powder content and has a relatively high fineness modulus. However, SS series sand collecting system reduces the erosion to 5-10%, solved this problem perfectly.

2.The viberating screen is equiped with polyurethane mesh of low blockage rate and is highly endurable.

3.The polyurethane lining increases the longevity of the whole equipment, and make the whole procedure more efficient.

4.Collects 85% of the sand in the mixture, which outstrips other equipments.

5.The sand is collected, which reduce the cleaning cost of drain trap.

6.The sand collecting system reduces natural heap or collecting time of the sand.

7.Solutions can be designed according to the expectations of clients.
