Pressure the ball machine is mainly used to suppress difficult molding powder materials, which is characterized by forming pressure, the host rpm adjustable, with a screw feed device. Host powered by electromagnetic speed motor, the pulley, spur gear reducer, coupling with spread through the rod axis. Driving shaft and the driven shaft through the open gear to ensure synchronous operation. Passive bearing equipped with a hydraulic device behind. 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 required is equal to the host screw feeder, you can maintain a constant pressure feed pellet quality and stability. Such as excessive feeding, feeding the power transmission 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 the pressure roller, 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. www.hndfzg.cn coal briquetting machine www.dondfang.cn drying equipment www.henandf.com ball press machine www.jqz3.com powder ball press machine
