How to Avoid Common Traps in Plastic Granulators? 1

Granulation has emerged to be one of the most vital steps in the manufacturing process. Regrinding is considered to be an evil in many industrial units.

However, plastic granulators and grinders are used as a cost-saving method and efficient marketing opportunity. This is so because industries nowadays are focusing on the production of those materials that are recyclable and appropriately match the enhanced standards of consumer expectations.

The reduced energy consumption and increased automation levels are cost-effective solutions provided by the improved cutting technology. It has further affected the grinders’ regrind quality, production rates, and machine designs.

Read below some common traps that should be avoided when working with grinders and plastic granulators.

1. Unsuitability of the Granulators with the Assigned Task:

For an effective granulation process, it is important to consider the plastic granulators’ horsepower and throat size. Before the product is ingested on the rotors, it is made to bounce through the cutting chambers for prolonged periods.

This lowers the poor regrinding quality of the plant. Furthermore, the granulators should aptly configure the task’s requirements to cut the material effectively. Not doing so results in high energy consumption levels, lowered capacities, and wear and tear.

2. Maintain the Granulators:

Often maintenance of the granulators after the cutting process is mostly ignored. This is so because their care requires a lot of time. Poor care and inadequate cleaning procedures tend to degrade the quality, leading to hefty fines and dust in various chambers of the granulators.

The main reasons for dusty chambers are the dullness of the gapped knives. Certainly fine, sharp blades will efficiently cut the scrap, absorbing less heat. Further sharp edges of the plastic granulators yield high throughput and finer cuts without any wear and tear.

3. Avoid Granulators with Poor Knife Designs:

Other problems with plastic granulators are knives with no scissors and inadequate optimization of blades. These problems generally lead to dust and fine granular contents, resulting in wear and tear.

Therefore, granulators with adjustable knives should be chosen. These flexible rotating knives can be bolted with rotors, kept sharp, and properly gapped. Adaptable cassette knives are the modern featured knives found in newly manufactured plastic granulators. They allow the knives to gap independently along the chambers, allowing for a minimum amount of material to ground off in the knives.

4. Avoid Over-Feeding the Granulators:

Over-feeding of the granulators tends to lessen the overall productivity. The resultant decrease in air flow leads to lesser evacuation of the machine design and the chambers of the granulators. A further collection of the materials over the knives adversely affects them, reducing their operating life and jams.

Moreover, in extreme cases, overfeeding maximizes the load capacities,, which ceases the overall working of the plastic granulators.
