SRL-Z Series High-speed Mixing Unit
Product Application
SRL-Z series mixing unit is mainly used for batching, mixing, coloring and drying resins such as PE, PP and PVC, etc. It also can be used for drying and devolatilization of engineering plastics such as ABS, PC, etc. before processing and mixing phenolic resin.
This unit combines hot mixing and cold mixing. After hot mixing the material will be cooled down during cold mixing so as to exhaust residual gas and avoid caking.
Product Features
This mixing unit is controlled by PLC. It is the ideal choice for plastic mixing because of high automation, good mixing effect, multiple functions, compact structure, and beautiful appearance, etc.

Main structure
The mixer consists of machine rack, driving unit, mixing drum, lifting device, material discharging unit and electric control box. The whole machine adopts reasonable and beautiful closed-type structure.
Driving unit: the agitating blade is made by stainless steel through special processing so it is wear-resistant and corrosion-resistant. The main shaft is of fine workmanship through finish turning & grinding, quenching & tempering. There are three seals to avoid leakage: tetrafluoroethylene, gas and skeleton type oil seal.
The mixing drum has multiple layers: inner, outer and sandwich layers. The inner layer is made by stainless steel through welding. Both inner wall and bottom of the drum are made by stainless steel. The bottom is circular-arc. Inner surface is very smooth and rigid so it is wear-resistant and corrosion-resistant, also the material will not easily stick on the drum. There are heating jacket and resistance heating coil in the sandwich layer. The drum will be evenly heated through high ignition point thermal oil in heating jacket. The material temperature in drum can be controlled by adjusting thermal oil temperature. The jacket is wrapped with asbestos insulation layer so hand will not be burnt while touching the outer layer.
The mixer cover is made by aluminum alloy. Inner face is of fine workmanship through finish turning and polishing. After being lifted by cylinder, it can vertically rotate and horizontally clockwise rotate (rotate 70℃). There is a hole opened on the cover for adding resin, plasticizer and stabilizer. Also there is a hole for exhausting gas. Customers can arrange according to production. The force should not be too large while rotating the cover so as to avoid hitting the drum wall. The mixer cover is fixed with protection cover, otherwise if the cover is not closed, operators may be hurt by the agitating blade.
The discharging device is made by aluminum alloy. It is fixed with pneumatic discharging door to automatically discharge material. Cylinder and discharging door is well connected resulted in reliable compression and good sealing property.
