New Craft Landing! Water-cooled + air-cooled composite cooling granulation production line launched to solve the pain points of plastic granulation industry

Recently, a set of water-cooled pre-cooling + air-cooled water removal two-stage composite cooling twin-screw pull bar granulation production line has been assembled and debugged in the equipment workshop, innovatively integrating the dual processes of water-cooled shaping and air-cooled dehydration, breaking the application limitation of single water-cooled and single air-cooled granulation equipment, and bringing a new efficient and low-carbon production scheme to the modified plastics and masterbatch new material industries.
Process iteration: Two-stage cooling complements each other, taking into account both molding and low moisture production
The whole production line consists of four core modules: co-directional twin-screw extrusion main engine, front water-cooled tank, rear all-stainless steel air-cooled conveyor line and traction pelletizer unit, forming a complete closed-loop production process. The raw materials are fed into the twin-screw extruder after proportioning, and the mixing and plasticization are completed under the action of high-temperature screw shearing, and the molten materials are extruded from the machine head to extrude continuous strip-shaped blanks; The material strip first enters the water cooling tank to be immersed and quickly cooled, and relies on the water body to quickly cool down and shape, so as to avoid the adhesion and deviation of high-viscosity materials such as EVA, TPR and soft PVC from the source; The shaped wet material strip is drawn to the rear end stainless steel mesh belt conveying platform, and a plurality of sets of high-power fans at the top of the equipment supply air downward, and the water stains attached to the surface of the material strip and the residual heat inside are blown off by air convection, and the deep temperature control and water removal are completed before entering the pelletizing process, so that the moisture content of the finished particles is greatly reduced, and the necessary rear-end drying process of the traditional water-cooled production line is omitted.
Widening of suitable categories to cover multi-domain polymer material processing
The composite process production line is compatible with the production requirements of multi-category plastic granulation, and can not only mass produce high-filling masterbatch such as calcium carbonate and talc powder, flame-retardant color masterbatch, but also adapt to the modification production of hard materials such as glass fiber reinforced PP; It can also overcome the processing problems of special materials such as soft elastomer and PLA full biodegradable material. Previously, soft rubber compound could not be directly air-cooled due to viscosity, and full water-cooled granulation had the shortcomings of high water content and high drying cost. The new equipment filled the gap of mass production equipment of two kinds of raw materials through two-stage cooling combination.
Outstanding advantages in cost reduction and efficiency enhancement, boosting the green transformation of plastic processing industry
Compared with the traditional single process equipment, the water-cooled + air-cooled composite production line has significant economic benefits and environmental protection value: compared with the full water-cooled production line, the comprehensive energy consumption is reduced by about 20% after the drying equipment is cancelled, which reduces the loss and mildew risk of raw materials caused by water absorption drying; Compared with the full air-cooled production line, the equipment can produce high-viscosity and easy-to-stick materials, and the applicable scenarios of products can be expanded by leaps and bounds. At present, the domestic modified plastics and degradable new materials industry continues to expand, and the composite cooling and granulation equipment, which takes into account both versatility and energy-saving, is becoming the upgrading and selection direction of mid-to-high-end plastic processing plants, which continues to help the rubber and plastic processing industry steadily upgrade towards low-carbon and refined production.
