How To Maintain The Plastic Crusher?
Apr 10, 2022
Plastic crusher is used to crush waste plastics and factory plastic leftovers. Plastic crushers are widely used in the recycling of waste plastics and the recycling of factory leftover materials. The motor power of the plastic crusher is between 3.5 and 150 kW, and the rotating speed of the knife roller is generally between 150 and 500 rpm. There are tangential feeding and top feeding in structure; The knife roller is different from the solid knife roller and the hollow knife roller.
The plastic crusher drives the moving cutter head to rotate at a high speed through the motor. In the process of high-speed rotation of the moving cutter, it forms a trend of relative movement with the fixed cutter. The gap formed between the moving cutter and the fixed cutter causes the cut of plastic crushing and shearing, so as to crush large pieces of plastic. The crushed plastic filters and outputs the size of plastic particles through the screen.
How to maintain the plastic crusher?
1. The plastic crusher shall be placed in a ventilated position to ensure the heat dissipation of the motor and prolong its service life.
2. The bearing shall be filled with lubricating oil regularly to ensure the lubricity between bearings.
3. Check the tool screws regularly. After the new plastic crusher is used for 1 hour, fasten the screws of the moving and fixed tools with tools to strengthen the fixation between the blade and the tool holder.
4. In order to ensure the sharpness of the cutting edge, the cutting tool should be checked frequently to ensure its sharpness and reduce unnecessary damage to other parts caused by blunt blade.
5. When changing the cutter, the clearance between the moving cutter and the fixed cutter is 0.8mm for crushers above 20HP and 0.5mm for crushers below 20HP. The thinner the recycled material is, the larger the gap can be appropriately adjusted.
6. Before the second start-up, the remaining debris in the machine room shall be removed to reduce the start-up resistance. The inertia cover and pulley cover shall be opened regularly to remove the ash outlet under the flange, because the powder discharged from the plastic crusher room enters the rotating shaft bearing.
7. The machine should be well grounded.
8. Regularly check whether the plastic crusher belt is loose and tighten it in time.
