How Screw Sand Washing Machine Work

screw washer

The internal structure of the spiral sand washing machine. The rotor of the spiral sand washing machine adopts a central structure. The spiral blades are installed on the central shaft and connected to the central shaft by a reducer for work. A device for mechanical classification based on the principle that the specific gravity of solid particles is different, and therefore the speed of sedimentation in a liquid is different.

The spiral sand washing machine is mainly composed of a tank body, a reducer, a motor, a central shaft, a spiral blade and a bracket. The bracket is welded on the central axis, and the spiral blades are tightened with bolts after installation, so that the blades do not sag or deform.

Structure Features/Benifits

1. High Integrity

Except for the product material stacking belt conveyor, the rest of the system is concentrated in a whole structure, while leaving a reasonable amount of maintenance and inspection space. High integrity is convenient and safe for storage or transfer at the construction site.

2. High Efficiency and Adaptability

The central stone washing system adopts the mixing principle of the mixer. The materials in the mixing drum are successively rolled, pushed by the spiral blades and rubbed between the materials. Suitable for a wide range of materials, and can be perfectly adapted to the diverse production environment.

3. Economy

(1) The storage hopper capacity reaches 8M3, which makes the loader reasonably arrange the loading time and avoids the loader frequently changing positions at different loading points and materials. The width of the storage hopper mouth is more than 3 meters, and the loading is easy.

(2)It is provided with a water tank for active compensation of water and rinsing when the product leaves the machine.

4. Wide Range Output

Compared with other sand washing machines, the structure is more reasonable, the working efficiency is more prominent and the technology is more mature. For sand and gravel producers, screw sand washing machines are more able to meet the demand of large output.

5. Flexible With Other Devices

LZZG Spiral Sand Washing Plant is the combination of Screw Sand Washing Machine and Fines Recovery Unit. It greatly compensates the recovery of the lost fine sand during the preliminary cleaning and screening, and the recovery of fine sand results in an additional income, which greatly increases the benefits of users.

Compare With Wheel Type Sand Washer

Most users like sand washing machines with powerful functions and wide application. Compared with the wheel bucket sand washer, although some fine sand is lost during the cleaning process, the spiral sand washer has a stronger cleaning ability and can effectively remove sand and gravel with serious mud impurities. Often used on large sand production lines.

wheel washer

The capacity of the wheel bucket sand washing machine is generally below 80 tons, which is suitable for small and medium capacity sand production line systems. Therefore, the price of the wheel sand washing machine is relatively low and it is an economical and efficient sand washing machine. Spiral sand washing machine has a higher price and belongs to the type of high-end large-capacity sand washing machine. If the content of sand and gravel is high or the output is to be increased, the spiral sand washer can also increase the length of the sand washer or double spirals.

In addition, when the screw sand washer is working, the material mainly falls from the upper part of the machine vertically into the high-speed rotating impeller. Under the action of high-speed centrifugal force, high-speed impact and crushing occur with another part of the material flowing around the impeller in an umbrella shape. After the materials collide with each other, the materials will form a vortex between the impeller and the casing. Finally, it is discharged directly from the lower part to form a closed circuit for multiple cycles. The required particle size of the finished product is controlled by the screening equipment. The shape of the spiral sand washer is long. If the output is large or contains more impurities, it is more convenient to use the spiral sand washer and the cleaning is more thorough.

How to Operation and Maintenance

1. When installing the spiral sand washer, it is necessary to ensure the rigidity of the installation floor and not to be too close to the water source. To prevent the equipment from being unstable due to long-term work.

2. Before starting, rotate the rotor by hand to check whether there is any abnormality in each part of the machine. The work area should not be piled with debris, and there must be sufficient lighting equipment.

3. According to the specific conditions of the site, the using unit can only operate after installing protective equipment on the V-belt.

4. When washing, the water level should be appropriate. If the water level is too low, the rotation of the spiral will not work, and then the quality of the gravel material will be greatly reduced. Therefore, it is very important to maintain a proper water level when working.

5. Repair and cleaning work are not allowed while the machine is running.

6. Do not add more than the specified size of stone. The machine should rotate in a fixed direction and must not rotate in the opposite direction.

7. When the machine is running, if abnormal vibration or sound is found, stop feeding immediately. After the materials in the box are exhausted, stop the machine for inspection immediately. After troubleshooting, you can continue to run. Stop the motor in case of tightness. Before starting, the material in the cavity must be cleared and started without load.

8. Cleaned materials are stored properly. The washed materials should be stacked in a special location and protective measures should be taken to prevent the materials from being contaminated again.

9. Daily cleaning and maintenance of spiral sand washer. After the sand washer is running for a period of time, regular cleaning and routine inspections must be carried out to ensure that the equipment’s working efficiency and the service life are extended.

10. Regularly inspect and replace the wearing parts of the spiral sand washer equipment.
