A Guide on How to Care for Plastic Granulators

by Michael M.

Plastic granulators should be cared for properly to ensure they remain effective and in good condition. The cost of these machines is high, and although they come with a warranty if bought from trustworthy dealers, keeping them free of damage is vital. You don’t want to spend thousands of dollars getting yours fixed or buying a new one in a short time.

After buying granulators, few people enquire about the maintenance process: how much it would cost and any other required requirements. You can view more about them, and we discuss the steps for maintaining a plastic granulator below.

A Guide on How to Care for Plastic Granulators

Below are steps to help you maintain your device for proper functioning.

The plastic granulators have oil inside them, so it’s good to replace them by draining them and refilling them with new and clean oil once in a while. If the oil is too dirty, the effective running of the machine is complex, and all its processes tend to perform slower than usual.

In addition, remove any dust from its surface or parts regularly, mainly if it’s located in a dusty environment. Dusting keeps the plastic granulator clean and, in extreme cases, prevents the clogging of some parts on the device. Put the motor in order every few days for easier cleaning and operations.

Always inspect the machine transmission couplings for complete damage or few faults. The early detection of minor problems in the device saves you money and allows you to fix them before becoming extreme. Failure to remove faulty couplings can result in further damages and more money spent. It also affects processing for several days until it’s fixed or you buy a new machine. Therefore, proper maintenance is essential to identify extreme problems and mild ones before more significant damage occurs.

Check every screw and mounting to see whether they are loose. Loose screws and bolts can get lost easily, affecting the entire machine and causing a lack of stability. The loose connections can also cause unnecessary accidents during the recycling process to you or any of the workers.

If you notice any problem, stop all operations that involve the device and have it checked immediately to avoid putting your workers in danger. You can choose to fasten the screws yourself or have the workers help you; alternatively, you can seek professional help if the problem is beyond your reach.

Granulator bearings are an essential part of the machine. Ensure you replace them after some time with grease and mechanical lubricants. Sorting and repacing should be conducted every six months as the bearings wear out and reduce their efficiency.

As mentioned above, the oils should also be replaced. Some companies do this before any recycling; however, the process can be costly, and with regular maintenance, there’s no need to change oils every time you plan to recycle materials.


Proper and regular maintenance of any equipment enhances durability and extends its life span. This allows you to maximize its benefits and save costs needed for repairs or complete replacement. In plastic granulator machining, caring for the motor is a great deal as it’s the focal point of all operations.
