Mixer's Nianpan floor, Nianpan outer wear shields were added to improve the rolling, grinding material effects and the whole life. Drums can be automatically adjusted in height Nianpan on the ground when faced with difficult material and the material is too thick layer of grinding wheel automatically rises to ensure safety. Purpose: foundry core sand mixed system, can be used for glass, ceramics, chemicals, building materials, and other industries granular or powdery type material mixed system. With the development of a high-speed high-pressure molding automatic production lines made of clay mixed with the emergence of a new type of wet sand mixer. Such structural features are installed mixer blade and with the eccentric portion of the blade mixer chassis sand above the high-speed rotor equipment manufacturers, chassis, clockwise rotation of the rotor and blades for counterclockwise rotation of the rotor The rotational speed is higher than the chassis speed. When sand, due to a sand mill having a rotor chassis motion opposite Mixer equipment, and different speed, then the molding sand in the chassis to obtain different speed difference between the sand to produce the corresponding friction and shear forces, to produce rubbing RESEARCH Mixed ﹑ ﹑ broken role, not only high efficiency, mixed, mixed sand made out of better quality. Experiments are carried out with a sand mill sand casting process performance experimental study of important equipment, experiments with Mixer, regardless of grinding wheel or rotor. Bowl, add the amount of sand are a 3 kg, the normal temperature of conventional experimental research performance (core) sand is mainly used type. When these studies the performance of sand mixer for tens or hundreds of grams per gram only by the amount of sand, such as thermal expansion when research will result in a waste of quality raw sand and binder, increasing the cost of experiments . In order to solve these problems, we have developed a first sand was only 250 g of experiments using a micro-mixer. The micro-rotor type mixer has a simple structure, easy operation, adjustable parameters clay sand sand plant, a small amount of sand, etc., through the experimental verification Qingdao Mixer equipment, quality, mixed with sand to reach the laboratory Mixer requirements, while reducing consumption of raw materials, reducing the cost of experiments Qingdao Mixer equipment, Qingdao Heng (certified), sand equipment provided by Heng Machinery Co., Ltd.
