Plastic shredders are used to shred waste plastics and factory plastic scraps. Plastic shredders are widely used in waste plastic recycling and factory scrap recycling. The motor power of the plastic crusher is between 3.5 and 150 kilowatts, and the speed of the cutter roller is generally between 150 and 500 rpm. In terms of structure, there are tangential feeding and top feeding; the knife roll is different from a solid knife roll and a hollow knife roll. Next, let's take a look at the maintenance methods and care precautions for plastic crushers.

How to maintain plastic crusher.
Some precautions for caring for plastic crushers.
First, the plastic crusher should be placed in a ventilated position to ensure that the motor works to dissipate heat and prolong its life. Second, the bearings should be regularly filled with lubricating oil to ensure lubricity between the bearings. Third, check the screw of the cutter regularly. After the new plastic crusher is used for 1 hour, use the tool to fasten the screw of the moving knife and the fixed knife to strengthen the fixation between the blade and the knife holder. Fourth, to ensure the sharpness of the knife incision, the knife should be checked frequently to ensure its sharpness and reduce unnecessary damage to other parts caused by the dullness of the knife edge. Fifth, when replacing the tool, the gap between the movable knife and the fixed knife: is 0.8MM for crushers above 20HP, and 0.5MM for crushers below 20HP. The thinner the recycled material, the larger the gap can be. Sixth, before the second startup, the remaining debris in the machine room should be removed to reduce the startup resistance. The inertia cover and pulley cover should be opened regularly to clear the ash outlet under the flange because the powder discharged from the plastic crusher chamber enters the shaft bearing. Seventh, the machine should be well-grounded. Eighth, regularly check whether the plastic crusher belt is loose, and adjust it in time.
According to the size of the crushed product, the general nozzle and defective products can enter the crushing chamber. If it is a thicker product or a rubber head, it is easier to crush it with a model with one or two levels of horsepower; depending on the size of the crushing chamber, the size of the crushed defective products or the nozzle should not be larger than the size of the crushing chamber; the output requirements of the plastic crusher vary according to different models. After the plastic crusher has been in operation for some time, it should be checked regularly. The hardware is removed, and if the bearing wear is low, it can be turned on a lathe to the correct geometry. At the same time, pay attention to the clearance between the eccentric shaft and the bearing bush and the mandrel and the bearing bush. If it exceeds 1.5 times, it should be replaced or adjusted with a pad. When choosing a plastic crusher, it depends on whether it is reasonable to change the screen and change the knife, whether the crushed material is uniform, whether the powder ratio is within the allowable range, etc. Good plastic crusher manufacturers have undergone strict experiments and verification. The blade is also very important, and the machining of the knife is even a big problem in making a plastic crusher. A good grinder starts smoothly, the safety part is well considered, and the protection is also done well.
