Brief Introduction to Dry Sand Washing Machines

Dry sand washing machines are a highly efficient sand washing machine that uses the most advanced technology and combines the actual situation in the domestic sand and stone industry. Dry sand washing machines are widely used in many industries such as construction site, sand making plant, hydropower station and concrete dam. This machine has the features of high washing efficiency, reasonable structure, big processing quantity, low energy consumption and small sand losses.

Performance Characteristics of Dry Sand Washing Machines

1. The dry sand washing machines are simple in structure and reliable in performance, and the drive bearing device of the impeller is separated from water and the wet materials, thus greatly avoid damage of the bearing due to water, sand and pollutant.

2. When used for washing sand in the sand and stone plant, this sand washing machine has more advantages compared with traditional spiral sand washer:

(1) The loss of medium and fine sand and stone powder is small and grading and fineness modules of the building sand washed by dry sand washing machines reach the stands of Building Sand and Building Gravel and Rubble stipulated by the government.

(2) Other than the screen, there are no other easy wearing parts.

(3) Dry sand washing machines has long service life and it can be used for a very long time without repair.

Working Principle of Dry Sand Washing Machines

When dry sand washing machines work, the motor drives the impeller to rotate slowly through triangular belt, reducer and gear, and sand and stone materials go into the washing chute from the feeding chute. Driven by the impeller, sand and stone materials will roll and grind with each other, and the impurities covering on the surface of sand and stone will be removed, and at the same time the moisture layer coated on the sand particles will be broken for the purpose of dewatering. When water is added, powerful water flow will form to timely bring away the impurities and foreign matters with small proportion and then they are discharged from the discharging mouth of the washing chute, and the clean sand and stone materials are brought away by the impeller and finally poured into the discharging chute from the impeller, thus completing the washing process.
