I.Plastic shredder can crush all kinds of plastic plastics, such as plastic profile, pipe, thread, film. Granule can be directly extruded as raw material for production.
The effects of technological parameters such as rotating speed, particle size, feeding speed and outlet position on the crushing effect of plastics were studied. According to its structural properties and plastic powder description, combined with the collision characteristics of high frequency, high speed, large stress and high strain rate in the pulverizer, a new viewpoint that the crushing effect belongs to brittle fracture is put forward. Crushing plastic material of plastic shredder, in the injection molding machine or granulator production of raw materials at the same time, the production of defective products and nozzle material, can be timely into the machine side of the plastic shredder.
II.Operation and precautions:
1. Switch on the power grid;
2. Press the inching button to run the machine;
3. Start and idle for 1-2 weeks;
4. Combined operation of transfer machine and shredder;
5. Check if there is no abnormality and send the starting signal.
6. During operation, the machinery and motor shall be free from vibration, sound and humidity shall be normal, and the temperature of each bearing shall not exceed 75℃.
7, The chain tightness of the transfer machine must be consistent, in the case of full load, the chain tightness is not allowed to exceed the length of two links, there shall be no stuck chain, chain skipping phenomenon.
8. After the fusible plug or explosive piece of the coupling joint of the retractor is damaged, it shall not be replaced by wood or other materials.
9, The safety device of the crusher protection network should be kept intact, in the process of work to often check, if there is damage should be immediately shut down.
10, The transfer machine tail protection and other safety devices must be guaranteed intact.
11, Transfer transfer machine.
iii.PET plastic recycle crusher through the motor to drive the knife knife plate at high speed, and in the process of high-speed rotation of the moving knife knife form the trend of the relative movement of the knife with the knife gap is formed between the shear plastic crushing incision caused by the large pieces of plastic are broken, broken after the plastic on plastic particle size through the screen mesh filter output.
