Spiral feeding device by electromagnetic speed motor drive pulley, worm reducer rotation will be pressure to force the material entered the inlet pressure. Because electromagnetic speed motor constant torque characteristics, when the pressure quantity and the amount of material equal to the desired host screw feeder coal briquetting machine, you can maintain a constant pressure feed pellet quality and stability. Such as excessive feeding powder ball press machine, the power transmission feeding device overload; feed rate is too small is not a ball. Therefore, the operation of skilled technical work is to ensure that the pressure of an important condition for the ball. Hydraulic protection means is the high pressure oil from the hydraulic pump into the hydraulic cylinder, the piston axial displacement. The former head of the piston rod connected to the bearing housing pressure to meet production requirements. When the intake pressure roller between the two materials into the metal block excessive or hydraulic cylinder piston rod pressure overload, the pump will be shut down, the accumulator pressure change dampening effect, turn back to the oil pressure relief valve, piston displacement so increase the gap between the pressure roller so hard object by hydrostatic pressure roller ball press machine, the system pressure back to normal, you can protect the pressure roller is not damaged. The machine can be adjusted according to pressure the ball pressure density requirements and production flexibility.
