What is a plastic granulator?

Plastic granulators are consumable products that make recycled plastic granules from consumable products. Plastic granulator is usually a seamless and self-contained product. Moreover, after feeding raw materials into the machine, the machine will automatically complete and produce recycled plastic granules. 

Most recycled plastic granules are polymer molecules with high molecular weight and different regeneration properties. So, the plastic granulator is also named after the product properties such as pp, PVC, and pe plastic granulator. 

How much does it cost to buy where?

To save production costs, all businesses are equipped with plastic granulators instead of hiring or outsourcing before manufacturing. Moreover, with increasing demand, the types of plastic granulators have also become more popular and famous. Customers are also easier to learn and choose.

  • PET PLASTIC granulator
  • PP, PE, nylon shredder machine
  • Pet plastic shredder, plastic bottle shell
  • HDPE plastic shredder
  • ABS, PS plastic shredder
  • PVC shredder.

Application of plastic granulator

+ Application: PVC granulator. Plastic granulators can use raw plastic products or scrap, recovered plastic, recycled plastic, PVC, PET, PP, PE, HDPE, PS, ABS, PA, PET bottle flakes, PP, PE film, etc.

Moreover, plastic granulators have many good points, such as beautiful shape, round and bright. It can add as many colors as possible, high quality, and high output. Tan Hung Plastic Granules Company specializes in supplying PVC, PP, PPR, PE, HDPE, PS, ABS plastic machines… as follows:

  • Plastic injection machine
  • Distribution line for PVC/HDPE/PPR pipes, aluminum-plastic composite pipes
  • Production line for coiled pipes, chicken intestines, corrugated pipes, ribbed pipes, mesh pipes, electrical conduit

Moreover, the plastic granulator is a kind of plastic extrusion equipment. It heats the plastic raw material back to liquid under the device’s pressure. It continuously extrudes through the extrusion die and then cools down to a state. In addition, thick filament glass, passing through a bead cutter, is cut into cylindrical or elliptical plastic beads.

Construction of plastic granulator

The main motor of plastic granulators (Server)

The main engine of the plastic granulator is the extruder, which is composed of an extrusion system. Moreover, there is a transmission system, a heating and cooling system, and a feeding system. Strong development of resources recycles and turns waste into treasure.

Extrusion system: consists of barrel, screw, mold, and filter. It melts plastic materials into pieces, granules, powders, blocks, or other shapes. And then stabilized at temperature and pressure, measured by the screw, and extruded from the mold.

Drive system. It is mainly composed of a motor, reducer, and belt. Its function is to drive the screw and make the screw achieve the parameter uniform torque and rotation speed of granulators. Given numbers (such as temperature, pressure, rate, etc.). Thereby extruding the product we want.

Heating and cooling system. It is mainly composed of a heater outside the barrel. A cooling element is installed inside the screw. In addition, the function of this system is to heat or cool the screw barrel. Moreover, it ensures the extrusion temperature of the product as required by the specification.

Feeding system. It is mainly composed of a hopper and an automatic feeding device. It has the function of supplying the necessary materials for the extrusion system stably and continuously.

Auxiliary granulating machine (sub-granulator)

Granulators

The main structure of the plastic granulator auxiliary machine is similar to the main engine. Its function is to continue the extrusion step and extrude the homogenous material.

Moreover, the difference lies in the plastic granulating mold, divided into two types: manual and automatic. The granulator needs to change the filter regularly to remove impurities. The extrusion mold usually has 18 holes. After the filter is blocked, the pressure of the extruder will be very high.

In addition, manually replacing the filter mesh will be more complex than automatic. Using an electric mold instead of a manual mold will save us more time and effort. The mold construction of Auxiliary machines with diverse and rich models.

Uses of the granulators

With unique screw designs and different configurations, it is possible to produce plastic types: PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, PMMA, and other plastic for recycling and color mixing granulation. In addition, the reduction gearbox adopts a high torque design, making the machine work stably and without noise.

Moreover, the screw barrel specially hardens, is wear-resistant, has good mixing efficiency and high output. The vacuum exhaust pipe design, or the design of the standard pipe mouth, can release moisture and exhaust gas during the process. The production process makes the discharge material more stable. The plastic particles are more durable and ensure the excellent quality of the product.

Plastic granulators are mainly used to process waste plastic film (industrial packaging film, agricultural film, greenhouse film, beer bags, bags, etc.). Moreover, this is the most widely used and popular plastic recycling processing machine type in the waste plastic recycling industry.

There are two ways to save energy. One is to keep the power part, and the other is to hold in the heating part.

Energy saving in power part: Mostly using an inverter, save energy through residual energy of the motor. For example, the real power of granulators is 50 Hz. In addition, you only need 30 Hz for production. The unspent energy will be wasted. So, the inverter will change the motor output power to achieve an energy-saving effect.

Energy saving in the heating section mainly uses an electromagnetic heating device. Moreover, the energy-saving rate is about 30%-70% compared with the old-fashioned resistor coil.

Features of plastic pelletizing machine

All recycled materials produced after sorting, crushing, and cleaning will not need to be shaken, dried, or sun-dried. And can be used directly for both dry and wet purposes;

  • From raw material crushing, cleaning, feeding, and finally, granulating is automated.
  • Make full use of a high-pressure frictionless heating system in granulators to automatically generate heat, avoid continuous heating, and save electricity and energy;
  • Moreover, using an automatic power distribution system to different places to ensure the regular and safe operation of the engine;
  • In addition, the screw barrel set is made of high quality and high strength carbon structural imported steel, with high strength;
