SME element is a mixing element in which a number of reverse shallow reflux slots are opened on the conventional forward conveying element. Usually used together with resistance elements, the material is conveying through a shallow groove on the edge to form a return flow of melt, improving the distribution ability.
Selection principle: Usually used in the melting zone.
1. The friction between the screw and barrelThe screw rotates in the barrel, and the friction between the material and the two causes the working surface of the screw and barrel to gradually wear: the...
The extruder screw runs for a long time in high temperature, high pressure, high mechanical torque and high friction environment. The process conditions of the screw barrel of the extruder require the...
During the extrusion process, the extruder screw may suddenly get stuck. At this time, if the protection device of extruder does not work, the operator should immediately stop the operation. More comm...
