Sand washer is used to wash the soil mixture and clean the material from mud and excess materials, as well as to produce the natural washed natural raw material in the production line. Sand washer is used to remove dust from the sand, which increases the quality of the sand. Sand washer is used to separate, wash and dust the product in crushing and processing facilities for minerals and sand and is usually installed under the first sieve.

Types of sand washer
- Single helical cochlear sand washer
Two cochlear cochlear sand washer
Two-axis envelope sand washer
- XSD Scrubber (mix washer)
Spiral sand washer:
In this type of saline sand, the material pours into the pond with saline sand and is directed to the outlet valve by a screw and the consumed water is directed from the canal into the pond and then out.
Factors influencing the capacity of the coil diameter are the screw rotation speed, the pond volume, the pitch and the length of the spiral.
These saline sands are used for washing natural 06 sand and have a mud outlet and 2 water inlets and are widely used in river and mountain materials. Salt sands are made in dimensions of 4.5, 7 and 9 meters in widths of 140, 120 and 100.
In special cases, for clean washing of sand, two saline sands are used in a row, which also increases the quality of sand.
If the cochlear sands have a hexagonal pond, their erosion rate will be significantly reduced and the useful life of the device will be increased.
One of the major differences between helical sands and other sands, including packet sands, is their wet output load.
Features and benefits of salt washers:
۱- Simple structure and ability to separate the heaviest dense soil
2- Easy maintenance and low wear
3- Saving water consumption
4- High durability
5- No pollution
Two-axis envelope sand washer:
These salt sands are used to wash wind sands and river materials. Pocket salt sands wash the sand in 2 stages and have 4 water outlets and 3 inlets. These saline sands are most used in windy sands or materials that have a lot of soil and the tonnage of these saline sands is 80 tons per hour, which are made in dimensions of 2 x 11 meters.
This device is an ideal device for high capacity lines. The very low speed of the rotating wheel (1 to 3 revolutions per minute) and the large pool of water that minimizes turbulence and the high height of the muddy water outlet all result in maximum sedimentation of the sand filler and unlike soft sand spiral sand, with Produces quality, high-quality granulation, with low humidity. The advantage of salted sand is that it is dry (low moisture) load.
Scrubber (mix washer):
This machine is suitable for washing raw materials that have a large amount of mud:
1- Soft rubbing 2- Throwing or hitting them 3- Moving the sand with the pressure resulting from the weight in the water The sand that has passed through the scrubber is poured on the vibrating sieve for granulation and this step is like On the sieve, in a specially piped way, water is sprayed on the sand with pressure, and the washed and granulated sand is removed from the sieve. The salt sand machine separates and excess water and particles are removed from the other side.
