A scrap rebar granulator, also known as a rebar cropping machine or scrap steel bar cutting machine, is a heavy-duty industrial machine designed to crop used and waste reinforcement bars into short, uniform pieces for steel recycling.
Unlike standard rebar cutters used on active construction sites, a scrap rebar granulator is built specifically for recycling yards, scrap metal processing plants, and demolition waste facilities where large volumes of twisted, bent, and rusted rebar must be processed quickly.
Our flagship rebar granulator is powered by a 37 kW pure copper motor, features a double-head cropping system operating at 120 cuts per minute, and can process rebar up to 32 mm in diameter. The entire machine weighs 4,200 kg (4.2 tons), constructed from 60 mm-thick steel plate for maximum stability and durability under continuous heavy load.
Rebar Granulator Applications and Industries
Our scrap rebar granulator is designed for demanding industrial environments:
- Scrap metal recycling yards — process incoming construction and demolition rebar into furnace-ready granules
- Demolition waste processing — cut rebar recovered from demolished concrete structures
- Steel mill feed preparation — produce uniform scrap feed for electric arc furnaces
- Construction site waste recovery — process off-cuts and bent bars from building projects
- Scrap metal trading companies — add value to collected rebar before selling to mills
- Port and logistics scrap processing — prepare compact scrap loads for export shipping
The machine handles deformed rebar, round steel bars, and threaded bars up to 32 mm in diameter, including bars that are rusted, bent, or recovered from concrete.
Why Do You Need a Scrap Rebar Granulator?
The global ferrous scrap recycling market was valued at $264.1 billion in 2025 and continues to grow as steelmakers increasingly rely on recycled scrap to reduce carbon emissions. Processing 1 ton of scrap steel saves approximately 1.7 tons of iron ore and 350 kg of standard coal. For recyclers, the value difference between loose tangled rebar and clean cut granules can be significant — cut rebar granules command higher prices because they are easier to sort, transport, and feed into electric arc furnaces.
A dedicated scrap rebar cutting machine solves three problems for recycling businesses:
- Volume reduction: Cropping rebar into short pieces (typically 30–60 cm) reduces storage and transport volume by 60–80%.
- Higher selling price: Clean, uniform rebar granules are classified as premium scrap and sell at higher rates per ton than tangled loose bars.
- Faster processing: At 120 cuts per minute on a double-head system, the machine processes several tons of scrap rebar per shift — far beyond what manual or light-duty cutters can achieve.
How Does the Steel Bar Pellet Cutting Machine Work?
The rebar cropping machine operates on a mechanical double-head cropping principle:
- Feeding: Operators load scrap rebar — straight or mildly bent — into the feeding channel. The machine can handle multiple bars at once depending on diameter.
- Double-head cropping: Two cutting heads operate simultaneously on opposite ends of the bar, cropping it into uniform short lengths with each stroke.
- High-speed cycling: At 120 cuts per minute, the machine completes 60 cropping cycles per minute across both heads, delivering high throughput for industrial-scale recycling.
- Discharge: Cut granules fall into a collection bin or conveyor below, ready for sorting, weighing, and transport to the steel mill.
The heavy-duty chain drive and 37 kW motor ensure that each cut is clean and forceful, even on rusted or work-hardened scrap rebar.
Key Advantages of Our Rebar Chopping Machine
Reinforced Steel Body
The entire machine is constructed from 60 mm-thick steel plate, delivering exceptional durability, rigidity, and shock resistance. The total machine weight reaches 4.2 tons, ensuring that the cropping action remains stable even when cutting multiple bars simultaneously. This solid foundation minimizes vibration, protects internal components, and extends the service life of the machine.
Heavy-Duty Chain Drive Shaft
Power is transmitted from the reducer to the gearbox through a thickened, integrated heavy-duty chain. This design provides a robust and stable connection that can withstand high-torque loads during continuous cropping operations. Unlike belt drives that slip under heavy load, the chain drive ensures consistent cutting force delivery.
37 kW Pure Copper Motor
The machine is equipped with a 37 kW pure copper-winding motor running at 1,450 rpm. Using 100% copper windings, this motor delivers reliable high-power output with excellent heat dissipation and energy efficiency. A quality machine demands a quality motor — this is the powerplant that drives the double-head cropping system at 120 cuts per minute without strain.

Benefits of Using a Scrap Rebar Granulator
Increase Scrap Value
Rebar granules sell at a premium compared to tangled loose scrap. Mills prefer uniform short pieces because they melt more evenly and are easier to charge into furnaces.
Reduce Transport Costs
Cut rebar pieces stack densely in containers and trucks. Loose tangled rebar wastes up to 50% of container volume — granules fill nearly 100%.
High Throughput
With 120 cuts per minute on a double-head system, a single machine can process 4–5 tons of scrap rebar per shift, replacing the output of multiple workers with manual cutters.
Built for Continuous Operation
The 37 kW copper motor, heavy-duty chain drive, and 4.2-ton steel body are engineered for daily continuous use in harsh recycling environments. The machine does not need to stop between cuts — it cycles automatically.
Low Maintenance Design
The chain drive system is more durable than belt drives and requires less frequent replacement. The thick steel body resists deformation and cracking under stress.
Why Choose Our Steel Granule Cutting Machine?
Industrial-Grade Construction
Every component — from the 60 mm steel plate body to the 37 kW copper motor — is selected for heavy-duty continuous operation. This is not a light-duty site cutter; it is a recycling plant machine.
Double-Head Efficiency
The double-head design doubles the cropping output compared to single-head cutters. At 120 cuts per minute, it delivers the throughput that commercial recycling operations require.
Proven Drive System
The heavy-duty chain drive connecting the reducer and gearbox has been tested under continuous high-load conditions. It provides stable power transmission without the slippage and wear issues common in belt-driven machines.

Steel Fiber Cutting Machine Maintenance Recommendations
To keep the industrial rebar cropping equipment running at peak performance:
- Inspect the chain drive tension and lubrication weekly
- Check the cutting blades for wear and replace when cuts become rough
- Monitor the motor temperature during extended operation
- Keep the gearbox oil at the correct level; change according to schedule
- Tighten all mounting bolts periodically, especially on the cutting heads
- Clean the feeding channel and discharge area after each shift
With proper maintenance, the machine is designed for years of reliable service in high-volume recycling operations.
