What are the causes and solutions for overloading of screw extruders?

1 Reasons and methods
1.1 The mud is too dry. At this time, the mud material that is too dry should be taken out first. It is best to remove the machine mouth and head, start the machine to drain the dry material in the mud tank before installation and operation, and appropriately increase the molding moisture within the specified range.
1.2 If the machine is shut down for a long time, the remaining materials in the mud tank will become dry and hard, which will not only cause severe overloading, but sometimes fail to start. In order to prevent this from happening, when the machine is shut down for more than 8 hours, do not turn off the water at the machine mouth. For the two-stage vacuum extruder, the mud material in the upper mud tank should also be properly supplied with water to keep it moist. If the machine is shut down for more than 2 hours, If it is more than 10 days, try to empty the mud before shutting down.
1.3 Precautions: When overloaded, the load of the motor remains high and the clutch slips. Do not force start at this time to avoid damage to related parts, or even cause major accidents such as crushing the mud tank and machine head.
