Plastic Granulator Granulation Method And Technical Characteristics


The traditional method of strip drawing is to stretch the strip through the cooling section (commonly water bath), sometimes causing the strip to fall or size inconsistency. This plastic granulator is common in polymers with poor melting strength, such as polypropylene, polyester and nylon. When the strip falls, the material is scrapped, so the operator needs to pay close attention. If strip drawing is not consistent, downstream grain should be screened.

Plastic granulator function:
Using special screw design and different configurations, 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. Reducer adopts a high torque design to achieve smooth operation without noise. Screw, barrel by special hardening treatment, with wear-resisting, mixing performance is good, high yield characteristics, vacuum exhaust or ordinary exhaust port design, can in the production process of water, exhaust gas discharged, using more stable material, more solid particles, to ensure the good quality of products.

Plastic granulator production principle:
Using high-temperature melting, plasticizing, extrusion processes to change the physical properties of plastic, plastic and plastic molding.

Plastic granulator use:
Plastic granulator is mainly used for processing of waste plastic film (industrial packaging film, agricultural film, greenhouse film, beer package, bag, etc.), woven bags, agricultural convenience bags, basins, barrels and bottles, furniture, supplies, etc., suitable for most common waste plastic, waste plastic recycling industry is widely used, is widely used, popular with users of plastic processing machinery.
Changing the screw shape design, increasing the screw thread spacing in heating can make the plastic in the barrel of full plasticization melting; Using variable diameter type, the relative service life of screw is increased technically. The use of high-strength 38CrMoAlA material improves the performance of the whole machine.

Plastic granulator barrel
The design of the barrel adopts 45# steel after fine processing quenching treatment with high hardness and certain wear resistance and corrosion resistance, and there is a certain size of slot at the end of the feed, convenient feeding.

Plastic granulator Heating system
The heating system is composed of a heating ring, which is distributed outside the barrel to heat and plasticize the material in the barrel evenly. It is controlled by the instrument on the electric cabinet to automatically adjust the change of the set temperature.

Plastic granulator Cooling fan
In order to achieve the stability of the temperature in the barrel, the cooling fan is added at the bottom of the barrel, which will automatically cool down when the temperature is too high through the automatic control of temperature, increasing the temperature stability of the barrel.

Plastic granulator The nose
In order to maintain the extrusion of plastic will not appear due to temperature reduction, insufficient liquidity, hinder extrusion. A heating ring with a certain power is specially added outside the nose to ensure the normal fullness of the discharge material. And the discharging hole set on the head of the machine is parallel to the 15 hole type, which increases the discharging amount and increases the production speed. Head structure type parallel extrusion head, thread connected with the cylinder, when replacing the net plate can save time and effort.

Pelletizing system
After cooling by the cooling system, the strip enters the granulator to roll and cut into granular form, which is convenient for packaging. The rolling feeding wheel is arranged on the grain cutter, which is driven by the motor to transfer the material to the body automatically, and the rolling blade inside the body is cut off.
