Cooling principle

After being cooled by the cooling tower, the circulating water enters the mixing barrel diversion layer through the water inlet of the mixing barrel to circulate and divert. Due to the diversion resistance of the diversion layer, the pressure difference between the water inlet and the water outlet will be formed (generally, the pressure difference is 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. By adjusting the water inlet pressure to control the water flow speed, so as to achieve the purpose of adjusting the temperature of the material in the barrel.
