Spend time shredding, not on maintenance

qr shredder

A single-shaft shredder, the QR, developed by Untha.

How does it work?

The goal for the QR was to engi­neer a maximum performance machine with simplicity at its heart, so recyclers can spend less time on the upkeep of the shred­der and more time shredding.

There are variable drive settings for optimum outputs, it can be reconfigured to tackle different input wastes and low-mainte­nance pusher technology contributes to maximum yield and uptime.

The shredder is controlled via a simple touchscreen panel with remote diagnostics for efficient maintenance.

Where would it ideally be used?

It is ideal for handling plastics – lump, film, drums and mixed rigids – production waste, pallets and waste wood for biomass. It can process up to 30cu m an hour.

How is it different?

Recyclers are being placed under mounting pressures, which means margins are often difficult to maintain. The QR is designed to achieve impressive results with minimal effort.

A simple preventative maintenance plan is all that is required to preserve optimal operational conditions.

What benefits does it offer?

The QR includes a resilient drive for machine longevity, low-wear parts and integrated gears for additional maintenance simplic­ity. These all contribute to this being a robust shredder with low whole life running costs.

This means that affordability of the equipment extends long beyond the initial purchase price.

What about maintenance?

The QR is designed so that main­tenance efforts are minimal. Untha’s own engineers provide routine service support but, on a day-to-day basis, clients’ own operators are able to conduct the machine upkeep with ease – and importantly, in an upright, ergo­nomic position.

Where has it been used?

Developed at our Austrian head­quarters, in conjunction with recy­clers worldwide, the QR was recently installed at Riverdale Paper in Gateshead.

The business is now tackling around five tonnes a week of plas­tic waste, including polypropyl­ene, HDPE and pre-consumer material from the automotive industry.

The QR reduces this plastic to a <30mm fraction which is then sold to reprocessors for granula­tion and recycling.

Cost?

From £1,800 a month.

Any savings?

The essence of this machine is to save operators time and money. The QR’s easy-access door, for example, facilitates a fast change of cutters in as little as three hours, to allow clients to switch from shredding one material to another.

The same door also allows a quick machine cleandown, and foreign objects can be retrieved safely and with minimal disrup­tion.

What is its life span?

The QR is supplied with a three-year warranty, but the operational simplicity means this shredder is built to last, with minimal fuss.

How is it future-proofed?

Ease of configurability guarantees maximum application flexibility for this challenging business envi­ronment. For example, the shred­der can produce a high-quality fraction for woodchip, biomass or briquetting. But, as at Riverdale, it is being configured to suit dif­ferent plastic grades too. The idea is one investment, multiple uses.

Any future applications?

With interchangeable screens of 12-100mm diameters for varied fraction homogeneity, the options are multiple. The machine could be achieving a G30 or G50 bio­mass specification for one client while tackling product destruction for another.

How many have you sold and where?

There are already 32 QRs in oper­ation throughout Europe.
