Compact powder press machine


Powder compact press machine operating principle:


The pellet making machine adopts the couple roller. Between the rollers, there is certain gap. Using double output shaft reduction machine, makes the couple roller in phase and run face to face. One group of roller axle seat is fixed and another group of roller axle seat is slipped. With the support of the pressure of hydraulic cylinder, they are close to each other and the hydraulic system can has the action of compensation and protection. In the surface of the roller, the hole (arc trough) of many shapes and same size are arrayed. According to the different compression rate of the materials, choose the trough of one roller aiming at the trough of another roller, or peak to trough. Two rollers is arranged in horizon. The powder material on itself weight is compulsorily feed into the gap between two rollers over the rollers continuously and equally. When the material enters into the gripping area, it is gripped by the roller. With the continuous turning or the roller, the occupied space of the material is less and less and gradually compressed and reaches the max value of the formation pressure. Then, the pressure gradually reduces. The flakes due to its elasticity and self weight breaks off the arc trough, sieves.
