Plastic Grinder Machine, RE Series Granulators for Plastic Scrap (RE8–RE40)

A plastic grinder cuts clean plastic scrap into uniform regrind that goes back into production or sells as raw material. Molding shops grind sprues, runners and rejects beside the press. Recyclers grind PET, HDPE and LDPE bottles and containers. Plants with bulky waste shred it first and grind the shredded pieces. The screen under the rotor sets the granule size, so the regrind is even enough to feed a molding machine or an extruder.

In the Indian market the three words describe the same rotor-and-knife machine. “Granulator” is the technical term, “grinder” is the common name, and “crusher” usually appears with bottles. Whatever the name, the working parts are the same: rotating knives, fixed knives and a screen that fixes the output size.

Granule size is set by the screen (mesh) under the rotor, 12–15 mm standard on RE-series machines, customisable to your requirement. Material keeps recirculating in the cutting chamber until it passes the mesh, so output is consistently below screen size. Note that the RE16 CB and RE20 CB blower configurations produce an uneven shred size, stated faithfully on their pages.

Yes, the RE8 is our smallest plastic grinder: 3 HP motor, 35–45 kg/hr, 8″×8″ throat and just 150 kg. It grinds PET bottles up to 500 ml and small molding scrap, and fits beside the press in a small workshop. If your volumes grow, the same design scales up through the RE12 all the way to the 75 HP RE40.

There is no list price: every plastic grinder machine price is quoted to the job. What decides it is the model and throat size, the motor (3 HP on the RE8 up to 75 HP on the RE40), base or CB blower model, MS or SS construction, the screen you need and options such as a conveyor or control panel. A small plastic crusher machine beside one press and an RE40 for a recycling plant are very different purchases. Our plastic shredder machine price guide explains each factor. Send us your material and daily volume and we will size the machine and quote it in writing.

It depends on what the line has to do. For one plant a plastic recycling machine is a single grinder beside the press. For another it is a shredder, a grinder and the conveying between them. The price follows the machines in the line, their capacity and motors, and how the material is fed and discharged. Tell us your material, the form it arrives in and your daily volume, and we will recommend the line and quote each machine. Planning a whole recycling unit? Our guide to plastic recycling plant cost covers the rest of the plant.

Sharpen the blades periodically, keep the cutting head lubricated, and never let metal objects enter the cutting area, because they break blades. Abrasive material such as glass-filled scrap wears the edges faster, so check them more often. We give blade sharpening guidance and supply spares across India.

Yes. Bring your actual scrap to our works in Andheri East, Mumbai, and watch it ground on the model you are considering. For export orders we fit motors wound for your country’s voltage and frequency. Our machines already run in Dubai, the UK, Egypt, Mauritius, Nigeria and Kenya.
