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

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

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

1.Unsuitability of the Granulators with the Assigned Task:

For effective granulation process, it is important to give due consideration to the horsepower and the throat size of the plastic granulators. Before the product is ingested on the rotors, it is made to bounce through the cutting chambers for prolonged periods of time.

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

2.Maintain the Granulators:

Often maintenance of the granulators after the cutting process is mostly ignored. This is so because their maintenance requires a lot of time. Poor maintenance 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 knives will efficiently cut the scrap, absorbing fewer amounts of heat. Further sharp knives of the plastic granulators yield high throughput and finer cuts without any wears and tears.

3.Avoid Granulators with Poor Knife Designs:

Other problems with plastic granulators are knives with no scissors and inadequate optimization of knives. These problems generally lead to dust, fine contents in the granulators, further resulting in wears and tears.

Therefore, granulators with adjustable knives should be chosen. These adjustable rotating knives can be bolted with the rotors and can be kept sharp and properly gapped. Adjustable, 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 of the Granulators:

Over-feeding of the granulators tends to lessen up 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 the knives, reducing their operating life and jams.

Moreover, in extreme cases, overfeeding results in maximizing the load capacities which cease the overall working of the plastic granulators.
