Thermocol Grinding Machine and EPS Grinder for Recycling

Yes. Thermocol is expanded polystyrene (EPS), chemically the same polystyrene used in rigid products. The working recycling chain in India is: grind the foam to beads, densify the beads into ingots or briquettes, and sell those to recyclers who convert them back into GPPS pellets for products like photo frames, skirting profiles and decorative mouldings. The chain breaks only when the foam stays loose: no recycler will truck air. That is why on-site volume reduction with a thermocol recycling machine is the step that makes everything downstream viable.

Because EPS behaves nothing like rigid plastic. A shredder or plain granulator needs material with mass that presses against the cutting edges. Foam is roughly 98% air, so it floats above the blades, feeds inconsistently and comes out as static-charged fluff, and measured in kilograms per hour the result is poor. EPS needs a grind-and-densify approach: a thermocol grinder with a blower breaks the foam into beads and blows them into bags, and a densifying step downstream compacts those beads into dense, saleable form. We say this plainly so you don’t buy the wrong machine, from us or anyone else.

We quote every thermocol recycling machine to your foam and your volumes, so there is no list price. The price depends on the grinder and its motor, the feed size your largest mouldings need, and whether a customised crushing system suits your stream better than a standard grinder. A densifier, if your buyer wants ingots, is a separate stage with its own cost. Our guide to plastic shredding machine price explains each factor. Send us your weekly thermocol quantity and largest moulding size and we will recommend a setup and quote it.

It depends on which thermocol machine you mean. Machines that make thermocol products, such as moulding machines for boxes and sheets, are a different category from recycling machines. On the recycling side, a thermocol grinding machine such as the RE12CB grinds foam waste into beads, and a densifier then compacts them. Raj Electricals builds the grinding stage and customised crushing systems, and quotes each one against your foam, your volumes and the feed size you need. Tell us what the machine has to do and we will quote the right one.

It depends on your buyer. If a local buyer takes bagged regrind for filler or void-fill uses, the grinder alone completes your job. If you intend to sell to polystyrene recyclers, who pay materially better rates, they generally want densified ingots, which means a melting/compacting stage after grinding. Raj Electricals builds customized machines to client requirements, so tell us your end buyer and weekly volumes and we will configure the right setup. Contact us to discuss your line.

Thermocol grinder sizing is quoted against your material and volumes rather than off a fixed chart, because EPS throughput depends heavily on moulding size and density, and the feed opening has to suit the boxes or inserts you handle. The RE12CB has a 12″ × 12″ throat, and its output on your foam is confirmed by a trial. See the RE12CB Grinder with Blower machine page for the machine, then send us your weekly thermocol quantity and largest moulding size for a recommendation.

Yes, and with EPS we strongly recommend it, because foam streams vary more than buyers expect (clean white mouldings, film-faced sheets and soiled fish boxes behave differently). Send or bring a sample lot and we will arrange a trial on your material. Contact us to arrange one.
