plastic granulator machine with conveyor 01

These heavy-duty plastic granulator machines, sometimes called plastic crushers, are essential machines for plastic recycling. These specially designed granulators are extremely durable and have the unique ability to quickly and efficiently cut a stream of plastic scrap into small uniform flakes or regrinds.

At the core of our plastic granulator machine is an open rotor mounted with heavy-duty knives in either a double-scissor cut or v-shape array based on your requirements. As the rotor is spun at high speeds, the rotor knives come in contact with stationary knives that are mounted within the cutting chamber. The material is continuously cut until they are small enough to pass through a screen filter.

Our standard plastic granulator houses 12 rotor and 3 stationary knives. All knives use only ultra durable D2 (equivalent to SDK11) high-carbon, high-chromium steel which ensures the longest usage times before requiring sharpening. All knives are easily adjustable with hydraulic assisted access to the cutting chamber.


Depending on your application, we provide both dry and wet plastic granulator machines. Wet granulators have an added water hose attached allowing a constant stream of water to be sprayed while the plastic is cut. This helps clean the plastic scrap while keeping the blades cool during operation.

As one of our most sold type of plastic recycling machine, these granulators are packaged in many of our complete recycling solutions including our popular PET bottle washing lines, plastic film recycling lines, and more.

Plastic recycling granulators are high-speed machines capable of cutting smaller-sized, thin plastics into flakes and fine regrinds. Due to it’s fast rotation speeds, the operator must be careful not to have hard contaminants such as metals or rocks in the input stream. Metals such as nuts and bolts will easily damage the machine including very easily chipping the cutting blades. To ensure metals are not not present, we suggest adding a magnetic suspension separator above the conveyor system.

Plastic shredder machines while also used in size reduction in plastic recycling are low-speed, more robust machines capable of cutting large pieces of plastic. They are also more forgiving with contaminants. Therefore, plastic shredders are often used in conjunction with granulators to precuts large pieces of plastic into suitable sizes.
