Sand washing machine: wheel type VS screw type

When it comes to sand washing machines, both wheel type and screw type are popular choices for cleaning and washing sand and gravel materials. Each type has its own set of advantages and is suitable for different applications. Here is a comparison between wheel type and screw type sand washing machines.

When comparing wheel type and screw type sand washing machines, several key differences emerge:

Function and Working Principle

Wheel Type Sand Washing Machine:

Uses a large wheel with paddles to agitate and wash the sand. As the wheel rotates, it creates a water flow that lifts and scrubs the sand, separating impurities.
The sand is fed into the center of the wheel and is thrown outward by centrifugal force, while water sprays continuously clean the sand.

Screw Type Sand Washing Machine:

Operates on the principle of a screw conveyor. The sand and gravel are transported along the screw through a water bath. The screw's rotation agitates the material, allowing water to wash away impurities.

Advantages

Wheel Type:

High capacity: Can handle large volumes of sand in a short time, making it suitable for large-scale production.
Simple structure: Easier to maintain and repair due to its relatively straightforward design.
Good sand grading: Can produce sand with a more uniform particle size distribution.

Screw Type:

Efficient cleaning: Ensures thorough removal of impurities, resulting in high-quality clean sand.
Lower water consumption: Generally uses less water compared to wheel type, which can be cost-effective and environmentally friendly.
Compact design: Takes up less space, making it suitable for installations with limited area.

Disadvantages

Wheel Type:

Higher power consumption: Due to the large size and powerful motor required to drive the wheel, it may consume more electricity.
More water splashing: Can cause more water splashing during operation, which may require additional containment measures.

Screw Type:

Slower processing speed: May be slower than wheel type in processing large quantities of sand.
More prone to clogging: The screw mechanism can be more susceptible to clogging if the sand contains large or hard impurities.

Choosing Between Wheel Type and Screw Type

For Fine Sand and Easy Operation:Wheel type sand washing machines are a good choice.
For Tough Impurities and Versatility: Screw type sand washing machines are more suitable.

In conclusion, the choice between wheel type and screw type sand washing machines depends on specific requirements such as production volume, quality of sand needed, available space, the desired cleaning efficiency and budget. Each type has its own unique advantages and disadvantages, and careful consideration should be given to select the most suitable one for a particular application.
