Plastic granulators are useful pieces of equipment, but it's important to know how to maintain them. Aside from proper cleaning and maintenance, granulators also require regular preventive maintenance to avoid major issues. Performing preventive maintenance is easy, but maintaining a grater can be a hassle. Here's a brief guide on how to care for plastic granulators.
Firstly, you must take care of the granulator's blades. These components are prone to wearing out quickly and are the most expensive part of maintenance. Depending on the geometry of the basic part that goes into the granulator, blade wear will vary. Sharp blades will improve energy efficiency, reduce material tearing, and reduce noise. To make sure that your granulator is safe to use, look for safety features such as multiple safety switches, power-assisted tilt-back hoppers, and rotor locking devices. You should also choose a granulator with easy-to-access screens cradles and an intuitive visual path.
The main problem that most plastic granulators face is dull blades. It's important to choose a machine that's compatible with your regrind needs and to make sure that you maintain it properly so it can continue to give high-quality granulation. For this, you'll need to carefully measure your waste and wash it thoroughly. Then, separate metals. Otherwise, your granulator will generate excessive fines and damage its blades.
Another important factor to consider is the condition of the granulator's bearings. These components should be replaced regularly, and they should be lubricated with grease or mechanical oils. However, you should check the alignment of the blades after each blade change. Before starting the unit, make sure that the rotor clearance is correct. As the main cause of failures in granulators, the bearings are the main cause of poor quality regrind. Hence, proper maintenance of granulators is essential for their performance.
When purchasing a plastic granulator, remember that the blades are the most expensive and highest-wearing component. The wear rate of the blades depends on the geometry of the basic part that goes into the granulator and the material that it grinds. The granulator's blades can be sharpened, so make sure they are regularly cleaned. The rotor must be clear before it can operate smoothly.
Aside from the blades, granulators also need regular maintenance. The blades are the most expensive part of a granulator, and the blades should be sharpened regularly to prevent excess fines. The blades should be kept in good condition. After the blades are sharpened, the rotor should be turned manually to ensure that they are in perfect alignment. As a general rule, you should check the blades every two to three months.
A granulator's blades are a significant part of the machine. They're the most expensive part, so they're a critical component of the machine. They're the most visible part of the granulator and should be sharpened regularly to avoid causing any problems. A good granulator's blades will reduce the amount of dust and fines that are generated by the device.
Grease and mechanical lubricants are important parts of the granulator. They should be replaced every six months to ensure maximum efficiency. If you're using a granulator that requires oil or grease, you should check its bearings on a regular basis to ensure that they're clean and free of contaminants. By checking the bearings, you'll be able to see if the parts need to be sharpened.
A granulator's electric motor is one of the most expensive parts. As a result, many suppliers choose inferior motors to lower costs. Although the faster the motor, it's not necessarily more efficient. A motor's speed and power efficiency are vital factors in the machine's crushing efficiency. In addition, a granulator's noise level should be relatively low.
