Pre dispersion of rubber additives, also known as rubber additives masterbatch. The pre dispersed rubber additive is based on polymer (generally EPDM, SBR, NBR, EVA) as carrier, adding rubber additive and softener. The traditional rubber additive is pre dispersed into the polymer by special process to obtain a uniform concentration pre dispersion (extrusion granulation). Predistributed rubber additive is an upgrade of traditional rubber additive. It has the advantages of no dust, easy dispersion, suitable for automatic weighing and automatic continuous low temperature mixing, improving mixing efficiency, good storage stability and so on. It has been paid more and more attention in the industry and has been widely used in rubber products.

Pre dispersing masterbatch rubber granulator

The main components of the granulator are as follows:

Head and die: the head is composed of alloy steel inner sleeve and carbon steel outer sleeve. The function of the head is to transform the material melt in rotating motion into parallel straight-line motion, to guide it into the die evenly and stably, and to give the material necessary forming pressure. The material is plasticized and compacted in the barrel, flows out of the machine head along the flow path through the head neck through the porous filter plate, and the pelletizer frequency conversion speed regulation is properly matched. In order to ensure the reasonable plastic flow path in the machine head and eliminate the dead angle of accumulated material, a shunt sleeve is often arranged with heating function. Transmission system: the function of the transmission system is to drive the screw, and supply the torque and speed required by the screw in the extrusion process, usually composed of motor, reducer and bearing, etc. The adjustment and stability of the screw speed is one of the important technological requirements of the main engine transmission. The screw speed directly determines the rubber output and extrusion speed. In normal production, we always hope to achieve high speed and high production. When the extruder requires the screw speed from the start to the required working speed, the speed range available for use is large. Moreover, the stability of the speed is required to be high, because the fluctuation of the speed will lead to the fluctuation of the extrusion quantity and affect the extrusion quality.
