1250 Ton Scrap Metal Shear: The Production Class
The 1250-ton class is where a scrap operation becomes a production business. Below it, machines are judged on what they can cut; at it, machines are judged on how consistently they cut it, load after load, as the feed varies week to week. The Q91-1250 is a production machine, and this article covers what that means: the published figures, the consistency question that decides the purchase, the material profile this class is quoted against, and how plant operations evaluate a shear at 160 to 200 tons a day.
For the framework that applies to every class, the general buying guide is the starting point; this piece is about what changes at production scale.
The Published Figures for the Class
| Specification | Q91-1250 |
|---|---|
| Rated force | 1250 ton |
| Typical output | 160–200 tons per day |
| Continuous cutting | 120 mm plate |
| Occasional cutting | 150 mm plate |
| Bale capability | Specified capability for baled scrap |
| Duty | Heavy-plate production lines, mill feeders |
The output band is the first clue: 160 to 200 tons a day is a production figure, not a yard figure. The second clue is the duty row — heavy-plate production lines and mill feeders, operations whose downstream customer has a charging specification and verifies it. The third is the bale capability row, because production intake includes baled material as routine rather than exception.
Consistency Is the Product
Mill and foundry buyers pay for specification compliance rather than tonnage on a scale. A production machine at 160 to 200 tons per day is judged less by what it can cut than by how consistently it cuts it — the same charge size, the same cleanliness, load after load, as the feed varies week to week. That consistency is the product, and it is what the class is specified to deliver.
Consistency comes from three places, and all three are in the specification conversation:
The build. Frame rigidity, blade alignment and hold-down specification decide whether the cut geometry holds as the material varies. At production duty those are specification items, not quality aspirations.
The clearance discipline. Blade gaps held to specification and edges rotated on schedule are what keep the cut uniform. A drifting gap produces a drifting cut, and the drift shows up at your customer’s furnace before it shows up in your maintenance log.
The feed. Sorted, oriented, charged to the band. Production lines sort at the gate because the specification they sell depends on what reaches the box — and at this tonnage, every unsorted piece is a specification risk with a handling cost attached.
Tell us the specification your downstream expects and the configuration and clearance specification are confirmed against it in writing at quotation. That sentence is the difference between a machine that produces a spec and a machine that produces scrap at a known rate.
The Material Profile at Production Duty
This class is quoted against a specific intake: heavy plate to 120 mm as a daily diet, occasional work to 150 mm, baled material as a routine fraction, and section steel that arrives at plant scale. Three questions map your operation against it:
- What proportion of your intake is baled? The bale capability specification follows the answer — density, wire type, and how cold the bales arrive.
- What is your heaviest routine piece? Not the heaviest ever — the heaviest in a normal month, measured. The blade configuration and hold-down follow that list.
- What specification does your buyer verify, and how? Charge length, piece size and cleanliness, and whether compliance is checked by sample or by load. The answer decides how much of the operation is a specification check rather than a production rhythm.
Downtime Arithmetic at This Scale
At 160 to 200 tons a day, downtime is not measured in hours — it is measured in furnace terms. A production line running at this tonnage loses the day’s plan when the shear stops, which is why the buyers at this class ask different questions than yards do. What is the seal specification? How long does a wear-part replacement take? What spares should be on the shelf before the first production shift?
Those questions are the reason the duty declaration happens at quotation rather than after delivery, and the reason the spares kit ships with the machine. The build answers the first; your inventory plan answers the rest — and both are part of the specification, not afterthoughts.
Where the Class Sits
| Class | Output band | Continuous / occasional | The operation it fits |
|---|---|---|---|
| Q91-1000 | 100–120 t/day | 100 mm / 130 mm | Mid-size plants, high-throughput yards |
| Q91-1250 | 160–200 t/day | 120 mm / 150 mm | Heavy-plate production lines |
| Q91-1600 | 200–240 t/day | 150 mm / 190 mm | Steel mills, three-shift continuous |
Below it the 1000 is the plant entry class, pairing with balers in staged lines. Above it the 1600 becomes a three-shift mill machine where downtime is priced in furnace terms. The 1250 is the production middle — and most operations that outgrow the 1000 land here rather than skipping a class.
The Duty Declaration at Production Scale
At 160 to 200 tons a day the duty declaration is not paperwork — it is the specification. Frame, hydraulics, cooling capacity, wear-liner strategy and the spares kit all follow the shift pattern and material mix you declare, and the differences between a two-shift build and a three-shift build are structural rather than optional. A machine quoted for the duty you wish you had fights the operation in year two; a machine quoted for the duty you run disappears into the production plan.
The same discipline applies to the material list at this class. Plate at 120 mm as a daily diet, baled material as a routine fraction, the occasional 150 mm piece when the week allows — the blade configuration, hold-down specification and bale capability detail are all quoted against that list. Send the three heaviest pieces from a normal month with the inquiry and the build is specified against reality rather than against a brochure average.
Presets and the Seasonal Mix
Production lines sort at the gate because the specification they sell depends on what reaches the box — and at this tonnage, every unsorted piece is both a specification risk and a handling cost. The PLC presets are where the specification becomes real: cut length set from the buyer’s charge spec, verified against the material, and re-checked when the mix changes seasonally. Demolition feed in one quarter and plate offcuts in the next are different operations sharing one machine, and the presets, rotation intervals and sorting gates all need review when the mix turns.
The Heavy Tail, Counted
One measurement decides the production class more than any other, and it is rarely taken: the frequency of over-class pieces in a normal month. A 130 mm piece in a 120 mm-continuous class is a bite the machine takes when the week allows — but if those pieces arrive weekly, the class is wrong, and no amount of blade discipline fixes a specification error. Count them for a month before the order. Weekly over-class pieces size for the next class; monthly ones keep this one with the right blade configuration. The count takes an afternoon and it is the difference between a production machine and a machine that fights its feed.
The Mill Buyer’s Verification
Mill buyers verify compliance on arrival, and the verification method shapes the operation. A buyer who samples occasionally lets you plan maintenance windows around production; a buyer who checks every load turns blade discipline into a contractual matter. Neither is better — they are different operations, and the difference belongs in the quotation conversation so the machine that arrives is configured for the verification your buyer actually performs. Tell us the method and the cut length, piece size and cleanliness specification are confirmed against it in writing at quotation, which is the last cheap moment to align the machine with the commercial reality behind it.
The Class You Did Not Ask About
One honest outcome of the production-class conversation deserves stating: sometimes the right answer is the class below. An operation at 120 tons a day of plate to 100 mm is a 1000-ton operation, and quoting it a 1250 because the budget allows buys force the material cannot use. The quotation names the class your numbers support, and at production scale the discipline to quote down is the same discipline that quotes up — the material decides, in both directions. Send the measurements and the written recommendation will reflect them, including when it is the class you did not ask about.
Buyer FAQ
What is the 1250’s daily capacity?
160 to 200 tons per day, with the position inside the band set by plate proportion, bale proportion, loading efficiency and running hours.
How is this class different from the 1000?
Duty and judgment. The 1000 is the plant entry class; the 1250 is a production machine judged on cut consistency against a downstream specification rather than on what it can cut.
What plate does it handle?
120 mm as the continuous daily diet, 150 mm as the occasional rating. Plate past 150 mm as routine points at the 1600-ton class instead.
Can it process baled scrap as routine intake?
Yes — bale capability is specified for this class. Send the bale density and wire type your intake produces and the configuration is confirmed in writing at quotation.
What commissioning support is available?
Test runs on your material, operator training across shift teams, and the first-month schedule around your production plan. On-site installation by our engineers can be quoted where the site requires it.
