How To Choose Plastic Pelletizing Machine To Make Quality Pellet?

What is Plastic Pelletizing System?

Plastic pelletizing is the process of converting scrap plastic back into a usable clean raw material. Plastic pelletizing includes melting and cutting polymers into easy-to-handle plastic pellets. Plastic manufacturers or processors can then reuse it for a variety of applications. The main machine of the plastic granulator is the extruder, which consists of an extrusion system, a transmission system and a heating and cooling system. Vigorously develop renewable resources and turn waste into treasure. Plastic Pelletizing Machine for recycling plays a crucial role to recycle and reuse plastic wastes.

1. Extrusion system. The extrusion system includes the hopper, the machine head, the plastic is plasticized into a uniform melt through the extrusion system, and under the pressure established in this process, the screw is continuously extruded into the head.

• (1) Screw: is the most important part of the extruder, it is directly related to the application range and productivity of the extruder, made of high-strength corrosion-resistant alloy steel.
• (2) Barrel: It is a metal cylinder, which is generally made of heat-resistant, high compressive strength, strong wear-resistant, corrosion-resistant alloy steel or lined alloy steel composite steel pipe. The barrel is mated to the screw to crush, soften, melt, plasticize, vent and compact the plastic, and to continuously and evenly convey the compound to the forming system. The length of the general barrel is 15 to 30 times its diameter, so that the plastic is fully heated and fully plasticized as a principle.
• (3) Hopper: The bottom of the hopper is equipped with a truncation device in order to adjust and cut off the material flow, and the side of the hopper is equipped with a viewing hole and a calibration measurement device.
• (4) Machine head and mold: The machine head is composed of alloy steel inner sleeve and carbon steel jacket, and the machine head is equipped with a molding mold. The role of the machine head is to transform the rotating plastic melt into a parallel linear motion, evenly and smoothly into the mold sleeve, and to give the plastic the necessary molding pressure. The plastic is plasticized and compacted in the barrel, and flows into the head molding mold through the head neck through a certain flow channel through the porous filter plate, and the mold core mold sleeve is properly matched to form a circular gap with a shrinking cross-section, so that the plastic melt forms a continuous dense tubular coating around the core. In order to ensure that the plastic runner in the head is reasonable and eliminate the dead end of the accumulated plastic, there is often a shunt sleeve, and in order to eliminate the pressure fluctuation when the plastic is extruded, there are also even pressure rings. The machine head is also equipped with a mold correction and adjustment device to facilitate the adjustment and correction of the concentricity of the die core and die sleeve.

2. Transmission system. The role of the transmission system is to drive the screw, supply the torque and speed required by the screw in the extrusion process, usually composed of a motor, a reducer and a bearing.
3. Heating and cooling device Heating and cooling are necessary conditions for the plastic extrusion process to be carried out.

Function

Using special screw design and different configurations, it is suitable for the production of PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, PMMA and other plastic regeneration and mixed color granulation. The gearbox is designed with high torque to achieve noise-free and smooth operation. Screw, barrel through special hardening treatment, with wear resistance, good mixing performance, high output characteristics, vacuum exhaust or ordinary exhaust port design, can be in the production process of moisture, exhaust gas discharge, so that the discharge is more stable, the rubber particles are stronger, to ensure the excellent quality of the product.

How to choose plastic granulator production line?

Many customers consult with manufacturers about plastic granulation production lines, what parameters are not, directly asked: how much is your plastic granulation production line? In response to such questions, enterprises often cannot answer quickly or cannot answer when quoting. Because of the different materials, the requirements for the equipment will be different, and the corresponding prices will be different.

As we all know, there are many types of plastics, we are divided according to the use of plastics, can be divided into two categories of engineering plastics and general plastics, general plastics refer to large output, low price, wide range of applications of plastics, PE (polyethylene), PP (polypropylene), PVC（polyvinyl chloride), PS (polystyrene) and amino plastics five varieties. Many of the products used in people’s daily lives, such as films produced with PE, woven bags made of PP, PVC plastic pipes, etc. are made of general plastic.

Engineering plastics are plastics that can be used as materials for engineering structures and as parts of metal manufacturing machines. For example, engineering plastics mainly include polycarbonate (PC), polyamide (nylon PA), polyoxymethylene (POM), polyphenylene ether (PPO), polyester (PET, PBT), polyphenylene sulfide (PPS), Poly (arylene ether) s (PAEs) and so on. When we choose a plastic granulation production line, we are selected according to the shape or material of plastic, such as film, woven bags, and other soft plastics as a plastic granulation production line; PET bottle flakes, filling, blending modification class for one production line; ABS, HDPE, and other hollow crushing hard materials for a production line.

Different models, configurations, prices will be different, and the same configuration, different production prices are also different, therefore, the specific need for what kind of model, how much output, the user needs to provide detailed parameters, so that we can make an accurate quotation.
