200L Dual Planetary Vacuum Mixer with Slurry Feeding System

200L Dual Planetary Vacuum Slurry Feeding System

1.Principle

The low-speed mixing paddle and the serrated dispersing disc installed on the high-speed dispersing shaft both rotate and revolve (each rotating on the axis of rotation, and at the same time rotating around the same axis around the container); at the same time combined with the low clearance of the mixing paddle Design, the low-speed stirring paddle makes the material produce strong kneading interference motion and up and down/left and right cyclic motion (from a macro perspective, the material collides, exchanges, squeezes, kneads/matches and circulates, and realizes the functions of mass transfer, heat transfer and reaction) ; The high-speed dispersing disc produces a strong mechanical and hydraulic shearing effect, which can fully/deeply disperse the materials; so as to finally ensure that the materials are fully dispersed and evenly blended (mixed).

7.Circulating cooling water of mixing tank

7.1 Cooling principle: Circulating water enters the diversion layer of the mixing bucket through the water inlet of the mixing bucket after being cooled by the cooling tower. Due to the diversion resistance of the diversion layer, the pressure difference between the water inlet and the water outlet (general pressure difference 2-3kg/cm²), so as to speed up the water flow and timely take away the heat generated in the mixing tank through the inner wall of the mixing tank. The water flow speed is controlled by adjusting the water inlet pressure, so as to achieve the purpose of adjusting the temperature of the material in the barrel.

7.2 Cooling water requirements:

A. After the circulating water is cooled by the cooling tower, the water temperature at the water inlet of the mixing tank is ≤10℃;
