Conical screw barrel maintenance guide

  • When the conical screw barrel is used for half a year, due to wear, the clearance between the screw and barrel must be checked every three months, and appropriate adjustments must be made.

    The gap between the screw and the barrel is directly related to the quality of the product, and the gap cannot be too large or too small. If the gap is too large, the shear rate will be low, the plasticizing effect will be poor, and it will be easy to burn. If the gap is too small and the shear rate is too large, the screw will scratch the barrel.

    Before measuring the gap between the screw and the barrel, the residual material in the barrel must be removed, and the screw shaft should be close to the distribution box.
