TSJ series two-stage granulator (also known as picture-machine): twin screw + single screw
Two-stage extrusion granulation machine has two bands: the first stage is TSSK-speed operation with the twin-screw extruder, can be forced feeding, efficient plastics mixing with shear dispersion, inorganic head backpressure reflux , to avoid overheating the high shear, for a second-order low-speed operation SJ series of large-diameter single-screw extruder, a single temperature control, low speed, low shear screw internal cooling before, to avoid the plastic material has been decomposed, ensure stable extrusion, two-stage extrusion granulation machine is widely used in heat-sensitive material system and a lot of devolatilization operations, such as PVC, XLPE, halogen-free flame retardant cable, shielding material, the high concentration of carbon black masterbatch, etc., can also be used waste (the material used is not clean), material for recycling large water granulation. The device may be the twin-screw extruder to achieve material shear, mixing, extrusion by a single screw extruder completed, the choice of materials. This device has two changer, first changer for filtering, the second for extrusion, two changer connection provided with an exhaust device, advanced scientific structure to avoid overheating caused material decomposition phenomenon. The unit can be used in soft plastic, hard plastic recycling, thereby achieving a multi-purpose function. Advantages: high yield, uniform particles, flexible operation, but high energy consumption.
