Find high quality rotor sand mixer machine with competitive price here. Please rest assured to buy rotor sand mixer machine with Qingdao Puhua Heavy Industrial Group

Description

It has scrapers and two high-speed rotors with a blade were installed in the machine's chassis. chassis rotates as clockwise, rotor and scraper rotate as counterclockwise. Rotor speed is higher than the speed of the chassis. Because chassis and rotor has an opposite movement, and the speed is different, so the sand of the chassis obtains different speed difference. Sand grains produce corresponding friction force and shear force, which causes the grinding, mixing, broken. This kind of machine not only mix with high efficiency, and the sand after mixing is good quality.  

Uses

Mainly used for casting workshop sand mixed, either mixed single machine molding sand can be mixed dry film sand, hard sand, the sand surface and core sand, glass, ceramics, refractories, etc. can also be used industry mixed a variety of powder, granular materials.
