For a medium-sized recycling yard, the two most common choices are a 160-ton and a 250-ton scrap metal baler. Both can be bought for a single mixed-ferrous yard, and both are built around a 25 MPa hydraulic system, so the real decision is not a matter of “power” but of throughput, bale size and the cost of running the machine all day. This comparison uses verified Wanshida specifications to show exactly where each machine wins. Choosing the wrong scrap metal baler for a medium yard means either paying for capacity you never use or running a press flat out that must be replaced within two years.
The Technical Principle Behind the Number on the Nameplate
Both machines are a scrap metal baler built on the same principle. The figures “160 ton” and “250 ton” describe the cylinder pushing force of the ram, not the total weight of the machine. Because working pressure is fixed at 25 MPa on both machines, the extra force of the 250-ton unit comes from a larger hydraulic piston and, in practice, from a larger press room and motor. That is why a jumping from 160 tons to 250 tons does not simply add 56 per cent force: it also adds chamber volume and power draw, which changes what the machine can do in a shift.
Real Working Conditions: What a Medium Yard Actually Feeds
A medium yard typically handles a mix of steel offcuts, thin profiles, baled aluminium, copper wire and occasional HMS. Feed is inconsistent, so the machine must tolerate both light and heavy charges. A 160-ton front-out press handles this mix at 22 kW, while a 250-ton turn-out press handles the same mix with greater margin and produces a heavier, denser bale that buyers pay more for. Feed inconsistency is the main reason yards over-specify their scrap metal baler, so measure a week of real feed before committing. The table below sets the two against each other.
| Parameter | Y83Q-160 | Y83-250UA |
|---|
| Press force | 160 ton | 250 ton |
| Max working pressure | 25 MPa | 25 MPa |
| Compress room size | 1450×600×600 mm | 2000×1750×1200 mm |
| Bale dimensions | (400–600)×600×300 mm | (~700)×500×600 mm |
| Capacity | 2000–2800 kg/h | 4000–6000 kg/h |
| Motor | 22 kW | 74 kW |
| Max material thickness | Light and thin | Up to 6 mm |
| Bale discharge | Front out | Turn out |
Calculation Example: Output and Power per Tonne
Assume a 10-hour shift. At a mid-range 2400 kg/h, the 160-ton machine processes about 24 tonnes of mixed scrap. At 5000 kg/h, the 250-ton machine processes about 50 tonnes, more than double. But power scales too: 22 kW versus 74 kW. Dividing power by throughput, the 160-ton machine uses roughly 9 kWh per tonne, while the 250-ton unit uses a similar figure per tonne despite its larger motor, because it moves far more material per stroke. The 250-ton machine therefore wins on labour cost per tonne, while the 160-ton machine wins on capital cost and is easier to power from a modest supply.
Which Should a Medium Yard Buy?
If your daily tonnage is under about 25 tonnes, or your material is light and thin, the 160-ton scrap metal baler is the better value and easier to run. If your daily tonnage is 25–50 tonnes, or you must produce heavy, market-grade bales from HMS and thicker ferrous, the 250-ton turn-out machine pays for itself through lower labour cost per tonne and higher bale value. Because both machines share the same 25 MPa pressure, the decision is really about volume and bale density, not raw power.
Buying Advice
Weigh three numbers before you choose: peak daily tonnage, the maximum thickness of your heaviest material, and your available power supply. Match tonnage to the chamber sizes above, confirm the discharge method fits your loader, and ask for the bale mass in writing. Finally, check the optional extras, because a feeding conveyor, oil heater or oil cooler can make a mid-sized scrap metal baler far more productive in daily use. A hydraulic metal baler is a long-term asset, so it is better to buy one size up than to run a machine continuously at its limit.
How to Decide Without Guesswork
Write down three figures before you compare quotes: peak daily tonnage, the maximum thickness of your heaviest material, and available power. Then map them onto the specifications above. If two figures point to different machines, let tonnage decide, because throughput is what limits a growing yard. Whichever scrap metal baler you choose, verify the bale mass and the discharge method in writing before you order, and ask whether the same scrap metal baling machine can later be fitted with options such as an oil cooler for continuous operation.
FAQ
Is the 250-ton machine worth the extra cost for a small yard?
Usually not. Below roughly 25 tonnes a day, a 160-ton press delivers the needed throughput with a smaller motor and lower purchase price, and it is simpler to run.
Can both machines use the same power supply?
No. The 160-ton press draws 22 kW while the 250-ton unit draws 74 kW, so confirm your transformer and cabling before choosing the larger machine.
Does a bigger bale always sell for more?
Heavier, denser, more uniform bales usually attract a better price and lower freight cost per tonne, which is a strong reason to choose the 250-ton machine in a growing yard.
What is the most important spec to compare?
Capacity in kg/h and bale mass, not the tonnage figure alone, because throughput and bale density decide your cost per processed tonne.
