As we have mentioned before, there are four main factors that affect the production capacity of crushing machines: raw material characteristics, supporting auxiliary equipment, problems with the crusher itself, and the configuration of the crusher's crushing hole.

The Canton Fair is currently underway, welcome to inquire!

The twin-screw feed extruder is mainly composed of a barrel and a rotating extrusion twin screw inside the barrel. When the equipment is running, the material enters the material chamber through the feeding port, and the screw rotates and extrudes forward to transport it. Under the action of thrust, friction, shear force and heat, a high pressure and high temperature difference is formed inside and outside the chamber. The moment the material is extruded, it expands instantly due to the pressure difference.

Before production, a comprehensive inspection must be conducted.
