spiral sand washer

What is Spiral sand washer?

A spiral sand washer is an industrial device used to clean and wash construction materials such as sand, gravel, and aggregates. This device is designed as a spiral system in which the materials move and are cleaned along their path through washing and dewatering.

The operation of this device is that, using mechanical force, sand or materials are directed into the device and then moved towards the device’s outlet through a helical screw (cone). In this process, excess materials such as dirt and mud are separated from the materials and finally, the clean and washed materials are directed out of the device.

This device is commonly used in construction industries, concrete production, mining production, and material production plants to aid in the application and process of producing high-quality materials.

The spiral sand washer is one of the important devices in the mining and processing industry, especially in sand and gravel factories. This device is used to wash sand and gravel and separate fine particles from the material. The main applications of the spiral sand washer are:

Sand washing: Spiral sand washing uses a stream of water to clean sand from contaminants, dirt, clay, and other fine particles.
Fine particle separation: This machine can separate sand and gravel from other finer materials such as clay or mud. This improves the quality of the final product.
Reducing material contamination: Using spiral sand washer reduces the amount of contamination in materials and results in higher quality products.
Increased productivity: A spiral sand washing machine with the ability to accurately separate particles can increase the efficiency of the production process and optimize water consumption.
Mining processing: This device is especially used in sand and gravel mines, soft rocks, and clay mines, and plays an important role in increasing the quality of extracted materials.

In general, spiral sand washing is widely used in the construction industry, concrete and asphalt production, as well as in mines for material processing.

How spiral sand washing works

How a spiral sand washer works: It is designed to effectively separate materials (such as sand, gravel, or aggregates) from impurities, mud, and other contaminants. This device uses a screw and a water washing system to perform the material cleaning process. The following is a step-by-step explanation of how this device works.

Material entry into the machine:

Materials (such as sand and gravel) are fed into the machine through an inlet. These materials are usually extracted from mines or from previous processing stages.
Materials are typically fed into the machine via a feeder or conveyor system.

Starting the washing process:

After entering the machine, the materials are fed into a washing basin containing water. In this section, the materials are washed with water to remove mud, dirt, and other impurities from the surface of the materials.
Water is continuously introduced into the machine (usually using a water pump) and excess material is removed from the materials through the water flow.

Helical screw rotation:

The machine has a screw (screw shaft) that is constantly rotating. The screw moves the materials upwards.
This screw is specifically designed to move the materials from the washing basin to the top of the machine while the washing operation continues.
The movement of the screw causes the materials to pass through the water evenly and be cleaned of impurities.

Mud separation:

In the process of moving the materials along the screw, impurities (such as mud) move downwards into the washing basin.
These materials are effectively separated from the materials and directed to the lower part of the device. Finally, the contaminated water, which contains mud and sludge, is discharged from the device.

Discharge of washed materials:

After the materials are thoroughly washed, they are directed to the machine outlet. At this point, the clean materials, whose impurities have been removed, are ready to be used in the next stages of the production process.
These materials are usually discharged from the machine in dry or wet form and sent to a tank or the next production line.

Contaminated water discharge:

The wash water, which now contains mud, is directed out of the machine through a drain system.
In some models, this water is recovered for reuse.

Draining impurities:

Mud and other impurities that have accumulated in the bottom of the wash basin are drained separately. Some machines have systems to collect these materials to prevent them from being discharged into the environment.

Important points in the work process:

Water: Water is essential for effective washing of materials and removal of impurities. In some machines, water is continuously recovered and reused.
Helical screw: The helical screw used in this machine moves the materials inside the machine and transports them to the top of the machine. This screw must rotate continuously so that the materials are washed evenly.
Settings: Some devices have the ability to adjust the speed of the auger or the amount of water input, which allows the user to adjust the device’s performance based on the type of material and washing needs.

Benefits of how it works:

Effective washing: The screw continuously moves the materials, which allows impurities to be effectively removed from them.
Continuous operation: The machine operates automatically and continuously washes and discharges materials.

Reduced water consumption: Due to water recovery systems, water consumption in these devices is reduced and water resources are used optimally.
