S3-600 Single Shaft Shredder, 650 x 600 mm Chamber, 30 HP

The side-feeding hopper opening is 600 × 1000 mm and the cutting chamber measures 650 × 600 mm, so most purgings, dead-heads, FRP sheets and planks go in whole, without pre-breaking. Whole large pallets are halved first, a minute’s work with a saw. If your pieces are unusually large, full-barrel purges from very big presses, for example. Send us photos with rough dimensions and weight, or bring a sample to our Mumbai works for a trial run before you decide.

Density. A solid lump or thick FRP board has no edge for dual-shaft blades to grip and tear, the way a drum or a bag does. The single-shaft design works differently: the slow 80 rpm rotor presses the material against fixed blades and shaves it down pass by pass, which suits dense, solid mass. Raj Electricals supplies both single and dual shaft machines, so the recommendation is honest. For hard lumps, composites and timber, the S3-600 is the machine we put forward, and for higher volumes of rigid engineering plastics, the S3-800 and S3-1000 take 400–600 and 600–800 kg/hr.

If you want extruder-ready regrind, yes. The S3-600 is the first stage: it turns pieces no grinder can swallow into smaller ones. An RE-series grinder then reduces those to uniform regrind sized by mesh. Many plants run the pair as a line, shredder feeding grinder, and convert lump waste back into material they can reuse or sell at regrind rates instead of lump-scrap rates.

Glass fibre is hard on cutting tools. That is precisely why this machine is specified the way it is. The blades are hardened to HRC 55–60, the chamber walls are 20 mm plate, and the rotor turns at a slow 80 rpm so the blades shear the laminate rather than smashing through it. Like any machine on abrasive duty, blades need periodic attention. The S3-600 is designed for easy cleaning and lubrication, and we provide installation and maintenance service on site.

Yes, incidental nails and staples pass through, at the honest cost of faster blade wear. Plan sharpening accordingly. Strip bulk hardware like hinges and brackets first, and keep other metal objects out of the cutting chamber. Output chip is good for biomass boilers, particle-board feedstock and composting bulk carbon.

The S3-600 is rated for continuous 24-hour operation. Construction is all metal with no plastic parts, the chamber walls are 20 mm plate, and the blades are hardened to HRC 55–60. Maintenance is mainly blade care and lubrication. Both designed to be easy, which is what keeps a continuously-run shredder healthy over the years. We provide installation and on-site maintenance service across India.

Every machine is quoted to the job. What moves the number is capacity, throat size, motor rating, MS or SS construction and the automation you add, a blower, a conveyor, a control panel. Our guide to what drives machine cost walks through each of those. Send us your material and daily volume and we will size the machine and quote it, usually the same day.

The standard drive is a 30 HP (22.07 kW) motor on 415 V, 50 Hz, 3-phase supply, normal Indian industrial power, with TP44 thermal protection. The hydraulic pusher adds a 2.2 kW oil pump motor. For export orders we provide a motor built for your country’s specific voltage and frequency, and we pack the machine for sea or air freight. Raj Electricals machines already run in Dubai, the UK, Egypt, Mauritius, Nigeria and Kenya. And before any purchase, you can bring your actual material to our Andheri East works and watch it processed.
