Both machine-made sand and natural sand are mixed with soil, dust and other impurities, which requires sand washing machine to improve the quality of sand. Therefore, the sand screening and washing machine has a high value in the market, and the equipment has a wide range of applications, such as river pebbles, weathered sand, stone powder, etc., which can achieve efficient material screening and cleaning.
Principle of sand washer
As a common sand washing device used with sand making machine, when it works, the motor drives the impeller to rotate slowly after reducing speed through V-belt, reducer and gear. Sand and stone aggregate from the feed tank into the sink, driven by the impeller rolling grinding each other, remove the dust, stone powder and other impurities on the surface of sand and stone, and damage the water vapor layer on the surface of sand and stone aggregate, which is conducive to the dehydration of sand and stone. Add water to form a strong water flow, and timely discharge the impurities with small specific gravity from the overflow outlet washing tank to complete the washing function. The cleaned sand aggregate is taken away by the blades and poured into the discharge tank from the rotating impeller to complete the sand cleaning function.
Because there are great differences in sand washing capacity per unit time, motor power and overall size among different types of equipment. The difference of these model parameters is closely related to the later production income of the equipment. It is suggested that users carefully check the parameter table of sand washer given by each manufacturer when purchasing the equipment, and then make reasonable purchase according to the actual production demand of their own enterprises.
