Which baler is right for your recycling yard depends on one variable above all others: your dominant material stream. Light mixed scrap and sheet need a compacting baler; car bodies and ELV fractions need a baler engineered for hollow, resistant shapes; long structural sections, pipe and plate need a shear baler that cuts as well as compacts; continuous industrial arisings need an automatic baler. Match the machine class to the material first — brand, size and options come after. This guide is that matching exercise, stream by stream.
Stream 1: light mixed ferrous scrap and sheet
Recommendation: a compacting baler (Roter RR series). If your intake is dominated by light mixed scrap, sheet offcuts, appliances and thin-gauge material, you need density, not cutting. RR series balers compact all kinds of ferrous and non-ferrous metal at 8–14 tonnes per hour on light mixed scrap, with three asymmetric cylinders per lid for fast box closure and processing. Configurations — fixed, semi-mobile, roll-on/off or three-axle trailer — fit the machine to the yard, and no foundations are required.
Stream 2: end-of-life vehicles and car bodies
Recommendation: an RR series car/ELV baler. A car body is engineered to resist crushing, which is exactly why generic compaction disappoints on ELV work. RR series machines process 15–20 tonnes per hour of end-of-life vehicles, and the no-foundation, semi-mobile options matter doubly here — many dismantlers grow yard by yard, and a machine you can redeploy protects the investment. Our dedicated guide to choosing a baler for automotive recycling goes deeper on depollution workflow and bale logistics.
Stream 3: long, heavy-gauge material — structural steel, pipe, plate
Recommendation: a shear baler (RR550.5, RR550.6 or RR715.6). When material must be cut to length as well as densified — demolition steel, long sections, mixed heavy scrap — the machine needs a guillotine. Roter shear balers deliver 550 tonnes of cutting force on the RR550.5 and RR550.6, and 715 tonnes on the RR715.6, with a 7″ colour touchscreen, radio remote, self-diagnostics and auto shut-off safety sequence as standard. If you’re weighing this class against a plain baler, our comparison of scrap baler vs shear baler settles the question in ten minutes.
Stream 4: continuous industrial arisings — turnings, cans, wire
Recommendation: an automatic baler (RA series). Where scrap is a by-product of production — machining turnings, canning offcuts, tyre-wire recovery — a continuous-feed automatic baling press converts the stream into dense bales with minimal labour, in a fully automated cycle of baling and ejection.
Cross-cutting factors that override the matrix
Mixed streams: most yards run more than one stream; size for the dominant one and confirm the machine handles the secondary streams acceptably — this is precisely what configurable machines are for.
Site constraints: if civil works are impossible or the yard may relocate, no-foundation and semi-mobile configurations move from nice-to-have to decisive.
Power: Roter machines run diesel as standard with electric motors on demand — grid availability and energy strategy may decide this for you.
The fifteen-year test: whichever class you land on, the machine will outlive several trends. Installation, operator training, technical assistance and guaranteed spare parts are what keep the recommendation true in year twelve — the full framework is in our procurement manager’s buying guide.
Frequently asked questions
Which baler is best for a scrap yard handling mixed light scrap?
A compacting baler sized to the stream — Roter RR series machines process 8–14 tonnes per hour of light mixed scrap, require no foundations, and configure as fixed, semi-mobile, roll-on/off or trailer versions.
Do I need a shear baler or just a baler?
If your material includes long sections, pipe, plate or anything that must be cut to length, you need a shear baler. If your material only needs densifying, a baler is the simpler, more economical machine.
What is the best press for end-of-life vehicles?
A baler engineered specifically for car bodies: Roter RR series machines process 15–20 tonnes per hour of ELVs, with semi-mobile, no-foundation configurations suited to growing dismantling operations.
How do I choose between baler brands once I know the machine class?
Compare force measured where the material resists, real throughput on your material, installation requirements, control systems, wear-part economics and the written after-sales commitment — then visit the factory of your preferred manufacturer.
