In the sand making process, the sand washer machine is an indispensable equipment. Sand with a lot of impurities and a large amount of mud will directly affect the quality of concrete. The sand washing link is an important link to improve the quality of sand and reduce the mud content. After comparison, the sand quality before and after cleaning will change significantly. Therefore, how to choose a suitable sand washing machine is very important.
Selection factors of the sand washer
For the bucket wheel sand washer, the effect of cleaning small particles such as sand is better. Its water consumption is small, and the water used in processing can be recycled. The loss of fine-grained materials is small, and the equipment investment is small, too.
The spiral sand washer for sale has large processing capacity and high efficiency. It cleans the sand more thoroughly and has a good cleaning effect for materials with more impurities. The spiral aggregate washing machine consumes a lot of water, the loss of fine sand is small, and the grading effect is obvious.
Appearance and Structure
The wheel-type small sand washing machine has simple structure, few wearing parts and small floor space. The transmission device is separated from water and materials to reduce the wear and tear on the equipment. It has a long service life and greatly reduces the failure rate.
The spiral sand washing equipment has a relatively long and narrow body. It adopts a horizontal structure, and is simple and straightforward. And the spiral sand washing equipment has a good sealing structure and a fully enclosed transmission device.
The spiral sand washer has a strong cleaning ability and can effectively clean sand with serious muddy impurities. It is usually deployed in large-scale sand production lines.
The capacity of bucket wheel aggregate washing equipment is generally below 80 tons, so it is suitable for small and medium-sized sand production line systems.
Common types of sand washers
spiral sand washer
Power：11-18.5 × 2kw
Water consumption：30-240 (m³/h)
Spiral sand washing machine is a kind of sand and gravel cleaning equipment with horizontal structure. It is equipped with a fully enclosed transmission device and an adjustable weir plate to ensure that the finished product is not contaminated. This can effectively improve the cleaning effect and ensure the stability of the fine-grained product.
The spiral sand washing machine sorts out the muddy impurities on the surface of the sand and stone through the rotation of the spiral blade. It cleans and sorts sand and gravel by means of the different specific gravity of solid particles and different settling speed in the liquid. During the entire cleaning process, the sand is continuously pushed in another direction with the acceleration of the spiral blade. The muddy impurities and rotten leaves with lighter gravity float on the surface and are stripped off.
Bucket-wheel sand washer
Bucket-wheel sand washing machine is also called impeller sand washing machine. It can remove impurities covering the surface of sand and gravel. At the same time, it destroys the water vapor layer covering the sand to facilitate dehydration and play a role in efficient sand washing and cleaning.
It includes V-belt, reducer, gear, impeller, washing tank and so on. The sand and gravel are tumbling under the impeller in the washing tank and grind each other to remove the impurities covering the surface of the gravel. Impurities are discharged from the overflow sink. The clean sand and gravel are taken away by the blades, and then the gravel is poured into the discharge chute from the rotating impeller.
Each kind of sand washing machine has its own advantages, we still have to analyze the specific situation. The most important thing is to choose the right sand washing machine according to your own needs.
