Plastic Granulator Crusher

Description

ASG’s plastic granulator, sometimes referred to as a “crusher,” cuts whole PET plastic bottles into small, uniform pieces, more commonly known as PET flakes.

Within our PET bottle recycling line, a wet granulator is utilized where an integrated waterline continuously sprays water into the cutting chamber. This feature serves two important purposes:

• The PET flakes undergo partial cleaning within the wet granulator.

• The water acts as a lubricant, reducing friction and heat within the cutting chamber. By adding water to the cutting chamber, we can decrease the frequency of knife sharpening by two to three times.

How It Works

To explain briefly how granulators work, at the core of this robust cutting machine is an open rotor mounted with knives in either a double-angle or v-shape array. This rotor, powered by a powerful electric motor, spins at high speeds within a cutting chamber where stationary knives are mounted.

As the PET bottles enter the cutting chamber, the spinning rotor knives come into contact with the stationary knives, creating a “scissor cutting” motion. As the rotor continues to spin, the PET bottles are cut into progressively smaller pieces until they fall through a sizing screen located at the bottom of the cutting chamber.

Models & Specifications

Our standard wet granulator houses 15 rotor and 4 stationary knives. Given the significant wear and tear on the knives, it is crucial to use only the highest quality knives available on the market today. Therefore, all ASG granulator knives are made from SDK11 (equivalent to D2 in the United States) high-carbon, high-chromium steel, which ensures extended usage times before requiring sharpening. Additionally, all knives are easily adjustable with hydraulic-assisted access to the cutting chamber, making knife exchange or sharpening straightforward and less time-consuming.

We offer a variety of granulator models for you to choose from, depending on the capacity requirements of your PET bottle washing line. Below are specifications of our standard granulators.

*Larger, more powerful granulators are available based on your request.
