Sell Tandem extruder

Mainly use for:
SPVC and RPVC compounding 
Crosslink PE or EVA with peroxide
Flame retardant materials with non-halogen and low smoking 
Wood and plastic compounded materials 
Heat sensitive reaction process

Function separation allows operation control flexibly. The first compounding twin-screw extruder runs at a high speed for good mixing and high output capacity. As no feedback pressure, over-heating and over-shearing can be avoided. The flowing equipment must be a larger diameter. The single extruder runs at a low speed. The screw inner cooling system can avoid the melt to be over-heated.
