and the rotor motor installed on the bracket, both by the level of transmitte narrow v-belt couplet of (5 V - 10604) and reducer pulley connection, again through the level of cylindrical gear reduction. The main motor driven hollow shaft by hollow shaft driven in scraper. Rotor motor drives the rotor shaft, drive the rotor and scraper relative motion. Reducer is fixed below the sand mixer chassis, the cabinet is equipped with a magnetic oil plug is used to collect scrap iron in lubricating oil, in order to reduce the gear and bearing wear, prolong its service life.
