What kind of machine is a plastic crusher? What is its use? When the injection molding machine or granulator produces raw materials, the defective products and nozzle materials produced can be put into the plastic crusher in time. After crushing, the raw materials and nozzles are crushed, mixed and formed to produce good products and recycled.

Structure of plastic crusher

The crusher is mainly composed of a blade spindle, a fixed knife, a carrying box, a box bracket, a feeding system, a power system, and an electrical control system.

1. Feeding system

The upper and lower bodies of the hopper of the plastic crusher are all made of high-quality steel plates by tailor-welding. The feeding hopper and the body are designed as double layers filled with sound insulation materials, so that the working noise is greatly reduced, so as to meet the requirements of environmental protection. The feeding hopper and the body are in a horizontal direction, which is convenient for feeding. The upper feeding port can be put into scraps and lumps. The lower and upper bodies are connected by joint bolts. Loosen the fastening bolts, and turn the lifting rod handwheel to connect the upper body and the feeding hopper. Jack up for easy cleaning. It is very convenient for use and maintenance to change the knife, change the screen and adjust the blade gap.

2. Knife roller

The knife is made of imported high-alloy steel D2, which is particularly strong and durable, and can easily crush all kinds of soft and hard plastics.

3. Power system

The only source of power for the plastic crusher is the electric motor that the machine is equipped with. The electric motor produced by the former state-owned factory Dongguan Motor provides a continuous, stable and powerful power for the entire plastic crusher.

4. Electrical control system

The machine electrical adopts the intelligent PLC control system, which can achieve anti-jamming and overload protection; the main electrical appliances are the well-known German brands Schneider and Siemens to provide security for the circuit control.

5. Carrying box

Front and rear sound insulation and soundproof design, the noise is very small. The design is simple, the floor space is small, and the maintenance is easy. The door is separated from the design, and it is very easy to clean and change the screen.

How Plastic Crusher Works

The plastic crusher we are talking about here refers to the toothed roller crusher which is the most commonly used and most suitable for processing plastics. The shearing of the material makes the material broken until it is smaller than the screen aperture and then leaks out to obtain fine broken particles. This principle is actually very simple, which is similar to the principle that we usually use scissors to cut paper. The fixed knife of the plastic crusher is like a fixed knife on the scissors, and the moving knife is the knife that makes relative motion to the fixed knife. In this way, the two knives cut the material sandwiched between them during the high-speed relative motion. And get fine broken particles.

The scope of application of plastic crusher

The plastic crusher can be used for the crushing of plastic bottles, shoe materials, sheets, plastic sheets, plastic pipes, medicinal materials, etc., resin, PVC, TPR, polypropylene polyethylene, high and low pressure polycarbon, rubber and other plastics. As long as it is plastic, the plastic crusher can handle it.
The plastic crusher has the characteristics of high speed, sharp blade, uniform crushed particles, small crushed particle size, and can be directly used for production of raw materials. There are various models of Gangsu Plastic Crusher, which can be designed according to the different needs of customers and the properties of different materials, and can be better matched with other equipment.
