There are tens of millions of sand washing equipment, among which spiral sand washing machines and wheel sand washing machines are better? Here, according to the different needs of customers, this article will take you to understand different sand washing machines from four aspects.
1. The difference in principle
The working principle of the wheel sand washing machine. After the motor of the wheel sand washer is decelerated by the V-belt, reducer, and gear, it drives the impeller to rotate slowly. The sand and gravel will pass through the feeding trough and enter the washing trough. As the impeller rotates, the sand and gravel rub against each other and become powerful. The water flow will hit the sand and gravel so that the covering on the surface of the gravel will be removed, and some impurities and foreign bodies with small specific gravity will also be taken away. After the cleaning is completed, the gravel will be brought into the unloading trough with the rotation of the blades, and the completion is Sand washing work.
The working principle of the spiral sand washing machine. This kind of sand washing equipment has the functions of cleaning, grading, and dewatering, and the spiral sand washing machine needs to be arranged in an inclined manner. The lower part of the water tank is surrounded by a three-sided weir to form a sedimentation tank. The screw head is immersed in the sedimentation tank. The motor drives the screw through the reducer to continuously rotate, and then the clean water is sent to the perforated plate at the bottom of the sedimentation tank.
2. The difference in the appearance of sand washing machine
The overall structure of the wheel-type sand washing machine is simple, with few vulnerable parts in the equipment, and small floor space after installation. To reduce the occurrence of damage to the bearings due to water, sand, and pollutants, this equipment is equipped with a structure in which the impeller drive bearing device is isolated from water and water-receiving materials, which greatly reduces the failure rate. However, the spiral sand washing machine has a slender body and a horizontal structure, which is simple and clear, but the installation and arrangement are not as convenient as the wheel type.
3. The difference between sand loss and cleanliness
The wheel-type sand washing machine consumes less water in the sand washing process, and the loss of fine sand and stone powder is very small. The sand grade and fineness modulus of the washed construction sand can meet the standard requirements. The spiral sand washer will filter out some fine sand during the cleaning process, so the washed sand will be particularly clean.
The cleaning ability of spiral sand washer is better than that of wheel sand washer, and it can effectively clean sand with serious mud impurities. It is usually configured in large-scale sand production lines. The capacity of wheel-type sand washing equipment is usually below 80 tons, so it is suitable for small and medium-sized sand production line systems.
4. The difference in the product price
The price of the wheel sand washer is relatively low, it is a cost-effective sand washer, and its operating cost is also very low. The spiral sand washing machine is expensive, and it is a high-end sand washing machine with large output.
It is not difficult to choose between a wheel sand washer and a spiral sand washer. You need to consider the composition of sand and gravel, estimated production capacity, production site conditions, and other factors. Both types of sand washing equipment have their characteristics. Choose the product that suits your production requirements to obtain better economic benefits.
