Three Factors Affect Quality of Plastic Granulator Particle


With the heat of the waste plastic recycling industry, the number of employees in the waste plastic recycling industry is growing, and the market is hot. How do users produce more high-quality recycled particles through plastic granulator equipment? In fact, to produce high-value recycled particles in line with market demand, there are three necessary conditions: high-quality raw materials, sophisticated plastic recycling granulation equipment and appropriate process. To make the extrusion of plastic particles have a higher standard rate, it is necessary to have skilled workers, in order to make the economic benefits of plastic particles manufacturers good, there must be strict requirements, sound safety management.

High quality plastic raw material requirements
What are high-quality raw materials? First, raw materials are selected according to the performance parameters of plastic particles. Second, the type of raw materials and processing technology to match, such as ABS has a grade one and two particles, for plastic pelletizer only use extrusion grade ABS waste. Plastic granulators with raw materials, most of which are granular materials, can also be directly recycled powder granulation, then use twin-screw plastic granulator production is best.

Excellent plastic granulator machinery equipment production line is a prerequisite
The main use is divided into two types of mechanical equipment: one is plastic granulator host, the other is broken for sorting, crushing, cleaning, cooling, cutting auxiliary equipment.

1. Plastic granulator host equipment
The recycling of waste plastics can not be separated from the plastic granulator. Usually, according to the types and characteristics of waste plastic, plastic granulator is divided into mother type (master and deputy machine), according to the different screw structure and number, and divided into single screw plastic granulator, twin-screw plastic granulator. Plastic granulator makes thermoplastic or thermosetting plastic in the heating barrel after heating, shearing, compression, mixing and transportation, melt plasticizing and homogenization; Then with the help of the thrust of the screw, force the high-temperature solution from the head of the mold head (plastic granulator mold) out of the stainless steel cooling tank after cooling and curing, in the more cutting mechanism into plastic regeneration particles. At present, plastic pelletizer has developed from a single type to a general, standardized, high speed, high efficiency, intelligent, energy-saving and other fine differentiation direction. As a professional plastic pelletizer company, it is necessary to understand the basic structure and working principle of plastic pelletizer, in order to use, maintenance and maintenance of the pelletizer as soon as possible, in order to give full play to the role of the plastic pelletizer.

2. Plastic granulator head (die head)
Mould head of a plastic granulator is a kind of equipment with a certain shape and size by extrusion of its own special shape, which is the most important equipment in the extrusion process of plastic recycled particles. Different waste plastic extrusion needs different die head matching, currently commonly used die head electric die head, hydraulic die head, due to the die head in the extrusion material through the sieve shaped into strip material, and through the die head at the same time, through the filter, to remove the impurities in the molten material. If the filter is blocked, it is necessary to replace the filter in time. The head of the traditional plastic granulator needs to be shut down when replacing the filter screen, which not only delays the time, but also affects the normal recycling of waste plastic granulation. After continuous technological innovation, the current hydraulic non-stop die head has realized automatic net change without shutdown, which greatly saves the time of the granulator and improves production capacity. A plastic granulator can choose from different heads and auxiliaries. Here we are talking about the auxiliary engine, by no means that it is unimportant. If there is no head and auxiliary machine, only the pelletizer, the same can not produce recycled plastic. The quality of the head directly affects the quality and cost of plastic particles. As a professional plastic pelletizer, it is necessary to fully understand the importance of the head and auxiliary machinery, know the infrastructure of the head and auxiliary machinery, learn to correctly use and maintain the head and auxiliary machinery, in order to increase its service life. For the technical personnel of plastic granulators, it is necessary to reasonably master the basic structural characteristics of the head and auxiliary machine and be familiar with the working process, so as to fully mobilize the role of the head and auxiliary machine in this field.

Good production technology and operation standard of plastic granulator
The suitable process also includes two aspects, one is the production process, the other is the main parameters of the process. The following is a list of examples of plastic granulator process: ① raw material preparation and pretreatment. (2) Waste plastic crushing and cleaning. Plastic granulator melt extrusion. (4) cooling. (5) the granule.
