Sand washing machine is widely used in construction sites, gravel plants, concrete hydro power dam site, and other industries, which has a high cleaning, reasonable structure, large capacity, low power consumption, less loss of sand during the washing process, particularly the transmission parts of sand washing machine are separated with water and sand, so the failure rate is much lower than the common sand washing machine, and sand washing is the best choice for upgrading the industry.Recent years, with metallurgical mining machinery industry market and to the high speed development of national energy saving, environmental protection, and the increase of demand, high technical content the washing equipment in the spring of development. With a large number of small metallurgy, small coal mine, small cement enterprise is closed, large new concentrator, large coal and large cement plant construction, this has to washing equipment put forward higher request, the urgent need to processing capacity, choose points high efficiency and reliable operation the washing equipment. Washing equipment including sand washing machine (sand washing machine), the sand machine system equipment and washing sand equipment. The use of advanced technology, combined with the actual situation of the developed sand industry efficient washing sand blasting equipment is the most desirable. This washing machine has the sand wash height, reasonable structure, the characteristics of production to wash in the process of sand, sand loss, especially the less transmission part are and water, sand isolation, the failure rate is much lower than at present commonly used sand washing machine, is the sand industry upgrading and wash the best choice.When the sand washing machine is running, the motor drives the impeller slowly turning through the belt, reducer, after the gear reduce the speed, sand and gravel are washed into the tank to the trough and driven by the the impeller, with tumbling and grinding...
