Compared with traditional extrusion equipment, Kolke’s self-developed screw components adopt wear-resistant alloy technology, and the hydraulic rapid screen change structure shortens the shutdown maintenance time, and reduces the energy consumption by more than 10% under the same production capacity. The models cover laboratory minicomputers (KTE-16) to large-scale mass production models (KTE-135), with a production capacity range of 100kg/h ~1200kg/h, which can match the differentiated production needs of small and medium-sized processing plants and large-scale new material industrial parks. It has served more than 3,000 enterprises at home and abroad, and its equipment is exported to more than 70 countries around the world.

KTE series co-directional twin-screw extrusion granulator completes the whole machine debugging work. As the mainstream core equipment in the field of plastic modification granulation, this equipment is widely recognized by industry customers for its mature process design and stable operating performance.
Relying on the co-directional twin-screw structure, equipped with a high-torque transmission system, and the building block screw combination design, the equipment can flexibly adjust the process module according to different raw material formulas, and fully plasticize, mix and disperse all kinds of polymer materials.
The equipment adopts the water-cooled granulation process of pulling strips, which is common in the industry. The raw materials enter the barrel through the feeding system, and the melting modification is completed under the action of twin screw shear. After the strip materials are extruded from the machine head, they are quickly cooled by the water-cooled tank, and finally processed into standard granules by the granulation device. The whole process runs smoothly, the finished product is in regular condition, and it is suitable for a variety of production scenarios.
At the practical application level, this model has a wide range of applications, and can meet various production needs such as plastic filling reinforcement, color masterbatch and functional masterbatch production, engineering plastics blending modification, degradable polymer material processing, etc. It is the key equipment in the production line of new rubber and plastic materials and plastic products enterprises.
As a professional R&D and manufacturing enterprise of extrusion equipment in China, Kolke has been deeply involved in the field of rubber and plastic machinery for many years. After continuous iterative optimization of its twin-screw extruder series products, the equipment stability, production efficiency and adaptability have been continuously improved. Relying on the standardized production workshop and perfect debugging system, the enterprise can provide customers with supporting services such as complete machine customization and strip testing, and continuously empower the intelligent and efficient production of the rubber and plastic 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.
