How to Deal With the Poor Water Resistance of Plastic Granulator?

Jun. 29, 2020

Nowadays, the plastic particles made by some small plastic granulators will have poor water resistance. How should we deal with them? Sometimes these particles are caused by many problems such as cohesiveness and insufficient raw material content. How can we solve it? As a Central Granulator Suppliers, share with you.

Increase the compression ratio of the mold plate of the waste plastic granulator and improve the crushing fineness.

Adjust the formula to properly increase the starch content, reduce fat and crude fiber, and add binders if necessary.

Increase the moisture of plastic raw materials and adjust the angle of the blades of waste plastic granulators in order to extend the conditioning time and increase the conditioning steam.

For the conditioner of plastic granulator and steam heating, we can add post-curing and stabilizing equipment.

At the same time, we must also pay attention to choose the cooling time and cooling air volume suitable for the waste plastic granulator to avoid the hardness and anti-wear performance of the granules being affected.

I believe many people are familiar with plastic granulators, but when it comes to the development of waste plastic granulators, I believe many people do not know.

The twin-screw waste plastic granulator used for thermoplastic processing in the world originated in Italy in the 1930s, while screw injections were made in Germany.

In the 50's and 60's, mixed twin screw extruder and large single screw extruder granulator appeared.

In the 1970s, the “building block” twin-screw extruder appeared, which was mainly used in the granulation process.

In the 1980s, twin-screw plus gear pumps, twin-screw plus single-screw tandem combined extruded waste plastic granulators appeared.

A few days ago, the classification of waste plastic granulators is divided into three types: large, medium and small, but there is no unified opinion. The size of the application of waste plastic granulators is temporarily divided. The waste plastic granulators for large-scale installations are temporarily It is designated as a large-scale plastic granulator unit, and China has also introduced large-scale ethylene plants with an annual output of 35,000 tons to 300,000 tons, large-scale polypropylene plants with an annual output of 35,000 tons to 140,000 tons, and small bodies The annual output of polypropylene plant is only 20,000 to 20,000 tons.
