Why Do People Want to Purchase Wheel Bucket Sand Washing Machines More Than Sand Screw Washers ?

A sand washer machine is necessary for washing equipment to wash artificial and natural sand in the mining and quarry industry. It can remove impurities covering the surface of the sand and the water vapor layer of the coated sand to facilitate dehydration and play an important role in efficient sand washing. There are mainly two kinds of sand washers, one is spiral (screw) sand washer, the other is wheel bucket sand washer machine. Although they both are sand washing machines, why people think the screw sand washer is not as good as wheel bucket sand washing machine? After a lot of research by China Fote Machine, it shows a couple of reasons as follows:

Differences between the wheel sand washer machines and spiral sand washer machines

Different working principles of the two sand washers

During operation, the motor rotates impeller slowly through the V-belt, reducer, and gear. When the sand enters the washing tank through the feeding trough, it will roll under the impellor and grind with each other to remove impurities from the water vapor layer covering the surface of the gravel which destroys coated sand to facilitate dehydration. At the same time, the sand washing process will create a strong water flow so that the foreign matter with small impurities and small specific gravity is taken away in time and discharged from the overflow port to complete the cleaning. At last, the clean sand is taken away by the blades then poured from the rotating impeller into the discharge chute to complete the cleaning of the sand.

besides these wheel bucket sand washer machine, there is portable sand washers

The spiral sand washer machine needs to be arranged obliquely. The lower part of the water tank is surrounded by three side slabs to form a sedimentation tank where the spiral head is inserted into. And the spiral is driven by the motor through the reducer to complement continuous rotation so that the washing sand process is finished when the porous plate at the bottom of the sedimentation tank is fed with water. This kind of sand washer machine has three functions of cleaning, dehydration, and classification.

So, from above, the working principle of wheel-type of the sand washer is simpler than the other, which may be one of the reasons why most of the people like wheel bucket sand washer machine.

Different structure appearances of the two washer machines

The wheel bucket sand washing machine has a simple structure which just needs less wearing parts and small occupied space. The impeller drive bearing device is isolated from water and water-receiving materials, which avoids the damage caused by water, sand, and pollutants, and greatly reduces the malfunction rate.
The screw sand washer machine has a relatively long body and a horizontal structure, maybe the structure of which is also simple and straightforward, but its installation is not as convenient as the wheel sand washer.

Different performances of the two sand washing machine when it comes to sand loss

For the wheel sand washing machine, the amount of water used in the sand washing process is small as well as the loss of fine sand and stone powder so that the grading and fineness modulus of the washed building sand can meet the standard requirements.
Compared with the wheel bucket sand washer machines, the spiral sand washer loses a lot of fine sand during the cleaning process, so it seems that the sand washing will be particularly clean.
Besides, the spiral sand washer machinery has a strong cleaning ability and can effectively clean the sand and gravel with serious mud impurities, and is often disposed in a large sand production line.
The capacity of the wheel bucket sand washer machine is generally below 80 tons, so it is suitable for the sand production line system of small and medium capacity.

Different price level of the two sand washing machines

The price of the wheel sand washing machine is relatively low, and it is an economical type of efficient sand washer machine. While the price of the spiral sand washing machine is relatively high, and it belongs to the type of high-grade large-volume sand washing machine.
And the wheel sand washing machine can freely choose to increase the number of grinding wheels according to the condition of sand and gravel. Therefore, the common equipment has a single impeller sand washer machine, a double impeller sand washer machine and three impellers one, etc. Of course, a fine sand recovery device can also be installed on the side of the washing wheel and docking installation is very convenient.

If the sand and gravel content is high or the output is to be increased, the spiral sand washing machine can also increase the length of the sand washing machine or the double helix side by side, so it also has a single spiral sand washer machine and a double spiral sand washing machine.

Why people choose the wheel sand washers?

Through the comparative analysis of the above aspects, do you have known the reason why the spiral sand washer machine is “poor performance compared with the wheel sand washer”? I think that it may be because the wheel sand washing machine is relatively cheap in price, perhaps its processing capacity is not as good as the spiral sand washing machine, but it can meet the requirements of most sand washing production lines, so users want to purchase the wheel sand washing machine with wider application.
