Countercurrent sand mixer
A new type of sand mixing machine for mixing clay wet sand with the development of a high-speed high-pressure molding automatic production line. This type of sand mixer is characterized by the installation of a scraper and a high-speed rotor with blades on the eccentric portion of the sander chassis. The chassis rotates clockwise, the rotor and the scraper rotate counterclockwise, and the rotor rotates faster than the rotor. The speed of the chassis. During sand mixing, because the chassis and rotor of the sand mixer have opposite movements and different rotation speeds, the sand shovel on the chassis obtains different speed differences, and corresponding friction and shear forces are generated between the sand grains, thereby generating shovel, mixing, The role of crushing, etc., not only the mixing efficiency is high, but also the quality of the mixed molding sand is good.
