The sand washing machine impeller (known as wheel sand washing machine), a high-efficient sand washing equipment in coordination with sand making machine, whichis manufactured and developed by Shanghai Dingbo Heavy Industry Machinery Companywith the advanced technology from home and abroad and based on the actual information about the domestic sand industry. In the wake of the constant development of industry and updates, the sand washing machine manufactured by Dingbo Heavy Industry Machinery Company is a new types of product that plays its role in construction sites, sand making factory and concrete batching plant, etc. The sand washing machine impeller is a washing machinery to dispose the sands and slag particle. It forms the drain trap under the slantly decorated sink and its screw head submerges into the drain trap, then the electromotor gives the screw rotation, which makes the bottom of the drain trap produce the water to complete cleaning, dehydration and classification. The structure of the sand washing machine impeller is very simple, its transmission bearing device is delicately designed and isolated from water, free from the damage caused by soaking and contamination.
