What are Washers Machines?

Sand and gravel washing facilities are important facilities used in the production of construction materials. In these facilities, wet processing and washing is a method used to clean and prepare natural aggregates such as sand and gravel. The process usually involves a combination of water, chemicals and mechanical processes. Separating coarse and fine materials, cleaning sand and gravel, and removing unwanted contaminants are important steps in this process. Wet processing and washing ensures that sand and gravel are made suitable for end use, thus achieving high quality results in the production of building materials.

The wet processing and washing process in these facilities generally consists of a series of stages. First, natural aggregates are transported to the starting point of the plant with the help of a feeder conveyor. They are then passed through a series of drums, washing tanks or vibrating screens where the sand and gravel are sorted by size and washed clean. During this process, water is sometimes combined with detergents and other chemicals, allowing the material to be cleaned more effectively. Finally, cleaned sand and gravel are usually dried and stored or incorporated directly into the manufacturing process of building materials. In this way, wet processing and washing plants serve as an important tool for producing high-quality construction materials.

Screw Washers

Washing screws can be produced with single or double helical shafts. It is driven by a geared motor and chain gear system. It is used for dewatering the washed and water-mixed materials. When the washed material is fed to the helix, it sinks to the bottom of the chamber thanks to its density and accumulates in this part. The spiral helix drags this material from the bottom to the outlet. In the double-shaft type, it carries the material to the center of the trough, ensuring the contact of the particles with each other, thus removing the unwanted parts on the particles.

Thanks to its inclined geometry, water is not included in this drag and is discharged by flowing through the channels connected to the lower collection chamber. The helix sheets in constant contact with the material are replaceable and protected against abrasion by plastic linings.

Crawler Washers

Blademill is generally used in the washing process when it needs to be processed before washing screens to improve screening efficiency or before other washing equipment such as vibrating washing screen, washing screw, dewatering screen to increase sand equivalent. It serves to purify the aggregate from soil, clay and other unwanted particles.

They are produced as double shafts. There are detachably fixed helix leaves and washing paddles arranged in the most suitable combination on the shaft. It is quite easy to replace the paddles and helix leaves as it has a detachable link. These shafts are driven by motor, reducer and belt pulley system.

With the design of the paddles and helixes aligned optimally along the shaft, the material is pushed towards the center and the unwanted particles on the material rubbing against each other are eroded and fragmented by this friction effect.

In appearance it is similar to washer screws. However, there is no water reservoir in the feeding part like the screw helix. Therefore, the fed material and the water exit the outlet chute together. In addition, both fine and coarse material can be fed, but they cannot separate hard and plastic clays. Moreover, as mentioned before, after the paddle washer, another washing equipment must be used.

Dewatering Screen

Dewatering screens are designed to remove water from sand recovered in a washing system. After any washing process, the sand contains a minimum amount of water. It may be possible at the end of weeks to drain this amount of water by stockpiling it in bulk. However, this also increases the inventory cost excessively. For this reason, dewatering screens are very valuable equipment for washing systems.

• Quickly removes the water contained in the sand.

• A product containing very low humidity is obtained.

The washed sand is fed to the inclined screen surface in the dewatering screen feed section. The screen frame is designed as upward inclined. As the material climbs this upward slope thanks to the linear motion created by the vibromotors, the water cannot climb and creates a pool at the intersection of the feeding and climbing motion. Therefore, liquid and very small organic fibers are separated from the sand through the mesh openings of the polyurethane screen wires, which have very small mesh openings, which act as a filter, and are forced to be evacuated from the screen. The received water is recycled for reuse in the system. The sand is obtained as dehydrated.
