Product Introduction

At present, there are a large number of sand washing, dehydration and recycling equipment manufacturers in the domestic market, and the equipment is uneven. In order to take the lead in the sand washing industry and better serve customers, the company has learned from both domestic and foreign sources Our sand washing technology has independently developed intelligent sand washing equipment, which dehydrates the cleaned materials and controls the moisture content of the finished sand. The sand washing has high cleanliness, minimal loss of fine sand, and large processing capacity. At the same time, we use hydraulic cyclone separation technology to thoroughly remove impurities such as silt and clay in the mud and sand, and maximize the recovery of lost fine sand. This equipment improves the quality of washed sand and achieves a reasonable combination of coarse and fine sand grading. At the same time, the device has a significant effect on the treatment of mud and sand with a very high mud content.

Equipment Composition

It is composed of high efficiency cyclone set, heavy linear vibration dehydration screen, wheel bucket type sand water separator, reducer, propeller pump, cleaning box, high return water tank, motor, wear-resistant rubber pipe and lining polyurethane elbow and other components.

operational principle

The sand-water mixture enters the cleaning box; By the wheel bucket type sand water separator; Then enter the heavy linear vibrating screen dehydration screen for dehydration treatment; The waste water flowing from the cleaning box (containing a lot of fine sand, mud paddle, dust and other impurities), Through the slag slurry pump delivery to the high-efficiency hydrocyclone, Then centrifugation grades concentrates the fine sand, Disrain into the heavy linear vibration dehydration screen through the sediment nozzle; Waste water, mud, dust, impurities in the cleaning box, The sewage treatment system discharged through the overflow outlet of the high efficiency hydrocyclone group; Dehydration screen screen surface out of the finished material coarse sand; High efficiency hydrocyclone bottom flow fine sand into the coarse sand for dehydration treatment, This can fully ensure that the thickness of the finished sand collocation is uniform and reasonable, At the same time, greatly reduce the problem of recycled fine sand into a lump, Higher quality of the finished sand, The granular grading is more even, Finished product sand is cleaner; At the same time, different product structures can also be designed according to the customers raw material properties.

Working principle

1. When dealing with sand with particularly high mud content and viscosity, the first step of the sand water mixture is Entering the spiral sand washing machine, the spiral sand washing equipment has the function of kneading, which can remove the viscous substances covering the surface of sand and gravel and wash away most of the soil. The effect is obvious in practice;

2. Through the spiral sand washing outlet, the sand enters the bucket type sand washing process. The washed sand is removed by the sieve on the bucket of the water wheel during the low-speed rotation of the water wheel, thereby reducing the moisture content of the sand and achieving the cleaning effect;

3. From the sand washing outlet of the wheel bucket, it enters the high-frequency linear vibration dewatering screen on the dewatering and recovery equipment for further dewatering, mud removal, and medium removal treatment, thereby reducing the mud content and moisture content of the finished sand; At the same time, the wastewater flowing out from the overflow ports of spiral sand washing and wheel bucket sand washing contains a large amount of fine sand. It enters the dehydration and recovery integrated equipment water tank through the overflow pipeline and is transported to After centrifugal classification and concentration in a hydraulic cyclone, the fine sand is discharged into the digging bucket of the wheel bucket sand washing equipment through the cyclone settling nozzle and mixed with coarse, medium and fine sand for dehydration treatment. This can fully The uniform and reasonable combination of coarse and fine sand in the finished product, as well as the fully recyclable fine sand, poses a problem. The quality of the finished sand is higher, the particle size distribution is more uniform, and the finished sand is cleaner;

4. At the same time, different product structures can be designed according to the customer's requirements for raw material properties.

Feature and advantage
