The rotor speed and the sand sand mixer time relationship

Sand mixer adopts rotor structure, depending on the productivity with 1-4 rotor sand mixer, relative to the different specifications of the sand mixer, molding machine and molding sand performance requirements, set different rotor speed at that time and the curve. Five stages in the process of sand (charging, two mixing, wet mixing, loose sand and discharging), because the water on the activation of bentonite is different, so the rotor resistance is different also. Feeding and dry mixing stage rotor, for instance, by the least resistance, can be quickly improve the rotor speed to add all kinds of high speed stirring and mixing. Wet when mixed with water and bentonite, sand viscous is more and more big, the rotor resistance is becoming more and more big, this time by rapid drop
