The scrap rebar granulator (automatic double‑end scrap rebar cropping machine / heavy‑duty scrap rebar cutting and cropping machine) can quickly cut waste threaded rebar into short segments. It improves the bulk density of materials for easier collection, transportation, and remelting in steel mills. The machine can handle rebar with a maximum diameter of 32 mm. Its double‑head cutting reaches a peak efficiency of 120 cuts per minute.
This model is specially optimized for common pain points in the scrap‑steel recycling industry. These include low manual cutting efficiency, vibration‑caused damage from weak machine frames, insufficient power for thick rebar, and frequent breakdown‑caused shutdowns. It is built with 60 mm thick steel plates and weighs 4.2 tons in total. Fitted with a 37 kW pure‑copper winding motor and heavy‑duty chain drive structure, it features rigid construction for long‑hour high‑intensity continuous operation.

- Steel mill raw‑material pretreatment workshops and construction‑waste processing factories.
- Overseas purchasers of metal recycling equipment.
Three Key Highlights of Scrap Rebar Granulator
Heavy‑duty reinforced structure for high‑intensity scrap steel processing
Constructed with 60 mm‑thick steel plates, the scrap rebar granulator machine weighs around 4.2 tons for robust frame performance.
The thickened frame and optimized transmission structure resist heavy impact and vibration generated during rebar cutting, improving operational stability.
A heavy‑duty integrated chain connects the reducer and gearbox to avoid loose connections in power transmission, making it suitable for long‑term heavy‑duty scrap steel cutting.
Heavy‑duty chain drive shaft for heavy‑impact scrap rebar cutting conditions
Utilizes a heavy‑duty, integrated chain to transmit power between the speed reducer and the gearbox. It effectively buffers the strong impact force generated during high‑frequency rebar shearing.
This design delivers a robust and stable power connection, reduces risks of chain breakage and transmission slippage, and guarantees reliable long‑term heavy‑duty operation of the whole machine.
37 kW pure‑copper motor for sustained cutting power
Equipped with a 37 kW 100% copper‑winding motor rated at 1450 r/min, it delivers stable power for cutting high‑strength threaded rebar.
Matched with an 850# reducer, it ensures reliable power transfer to the cutting mechanism.
How Does the Scrap Rebar Granulator Work?
- 喂养: Feed waste threaded rebar and round steel into the double‑side inlets; materials can be loaded from both sides simultaneously.
- High‑frequency cutting: The motor drives the reducer and heavy‑duty chain to actuate the cutting mechanism, which reciprocates at high speed to cut long rebars into short segments.
- Automatic discharging: Cut rebar granules are discharged from the bottom outlet. A hopper or conveyor can be connected for direct transfer and stacking.
- Continuous operation: Keep feeding materials to realize large‑volume continuous cutting of waste rebars.

Key Selection Tips for Purchasing Scrap Rebar Granulator
- Rebar Diameter: Choose heavy‑duty Model 850 for 28‑32 mm thick threaded rebar. Light‑duty models work for rebar under 20 mm. Small machines shall not be used for thick rebar to avoid stalling, gear damage, and frame cracking.
- Daily Capacity: Double‑head model (120 cuts/min, dual‑port feeding) for high output, higher efficiency than single‑head type. Single‑head is fit for low‑volume processing.
- Machine Build: Avoid low‑cost thin‑frame units prone to vibration‑induced cracking. This 4.2‑ton machine adopts 60 mm thick steel plates for heavy‑load service.
- 发动机: A pure-copper motor is preferred. Aluminum‑wound motors easily burn under heavy load. This unit is fitted with a 37 kW full‑copper motor for long‑time continuous operation.
- Transmission Parts: Heavy impact occurs during cutting. Heavy‑duty integrated chain plus heavy‑duty reducer improves shock resistance and reduces downtime.
- Site & Auxiliaries: A hardened cement floor is required. Feeding racks and discharge conveyors are optional to cut manual labor.
常问问题
What size of rebar can it cut? Can it cut threaded rebar?
Model 850# cuts threaded rebar and round steel up to 32 mm in diameter. Common 12‑32 mm waste construction threaded rebars are fully applicable.
How many cuts can the scrap rebar granulator make per minute? What about output?
Max. 120 cuts per minute for double‑head cutting. Actual output varies with rebar size and feeding continuity. Double‑side feeding doubles efficiency compared with single‑head machines.
The machine weighs 4.2 tons. Is a foundation required for installation?
A hardened cement floor is recommended. A simple concrete base is preferred if conditions permit to reduce vibration and extend service life.
Are wearing parts such as chains and blades easy to replace?
Blades and chains feature simple structure and good part compatibility. Original spare parts are continuously available from the manufacturer.
Can heavily bent waste rebar be processed?
Slightly bent rebar can be processed directly. Heavily knotted or twisted rebar needs pre‑treatment to avoid material jamming.
Can the machine run 24 hours non‑stop?
As a heavy‑duty industrial model, it supports long-term continuous production. Regular lubrication and wear inspection for chains and blades are required.
