SVL 3 or 4 Shaft Rotary Shear uses a combined hydraulic and electric motor drive system, integrating the flexible adjustability of high-torque hydraulic drive with the high efficiency and energy-saving benefits of electric motors. It is designed for heavy-duty waste processing and applications requiring uniform particle size. The equipment is widely used for pre-processing industrial waste, medical waste, construction debris, metal scrap, and other materials, providing efficient solutions for subsequent incineration, compression, or recycling.

Note: The above data are standard configurations for typical models and can’t be taken as the only principle for type/model selection, and such facts as kind of wastes and their states, type of package, expected size after shredding etc. should also be taken into consideration, actual data are subject to adjustment according to specific requirements. More models and configurations are for inquiry and for face-to-face discussion.

Shaft Rotary Shear Features
1. Provides up to 400 kW total power, allowing the shredder to process heavy, compacted, or fibrous industrial waste without stalling, ensuring continuous operation in high-throughput lines.
2. Cutting width can be modified between 20–100 mm to match downstream requirements, reducing clogging and improving uniform particle output for combustion or recycling systems.
3. Rotor and knife assemblies use hardened steel alloys, extending service life up to 10,000 operating hours under typical industrial waste conditions.
4. Individual knife and rotor modules can be replaced within 2–3 hours, minimizing downtime and maintenance costs.
5. PLC-controlled operation with overload protection, emergency stop, and automatic reverse function for jammed materials, reducing risk of unplanned shutdowns.

Shaft Rotary Shear Applications
1. Industrial Waste Processing: High-capacity shredding with wear-resistant rotors reduces volume of plastics, rubber, and metal scrap, lowering storage and transportation costs, while ensuring consistent particle size for downstream recycling or energy recovery.
2. Medical Waste Handling: Adjustable cutting parameters and enclosed design safely process medical waste, minimizing operator exposure and ensuring regulatory compliance.
3. Construction Waste Pre-Treatment: Powerful motors and high-torque shear action break down bulky debris and building materials, facilitating subsequent crushing, incineration, or recycling.
4. Waste-to-Energy Feedstock Preparation: Uniform particle size improves combustion efficiency and reduces risk of blockages in rotary kilns, fluidized bed, or gasification systems.
5. Biomass and Organic Residue Processing: Handles fibrous or high-moisture biomass, producing consistent particle sizes suitable for pelletizing, biofuel, or composting operations, increasing plant throughput and energy yield.

How to Choose the Right Rotary Shear
When selecting between a 3-shaft and a 4-shaft rotary shear, consider your waste type, processing capacity, and particle size requirements.
3-shaft rotary shear is suitable for medium-capacity operations handling industrial, municipal, or moderately bulky waste. It offers a processing capacity of 3–8 t/h and produces uniform particle sizes between 30–80 mm. Its simpler maintenance, lower energy consumption, and lower upfront investment make it ideal for facilities with moderate throughput or softer, less compacted materials.
?
4-shaft rotary shear is designed for high-capacity or heavy-duty applications, including RDF/SRF feedstock, biomass, and fibrous or compacted industrial waste. With a processing capacity of 5–15 t/h and adjustable output sizes from 20–100 mm, it delivers higher torque, superior particle size consistency, and reliable performance in demanding conditions. Its robust design, wear-resistant components, and modular maintenance system make it suitable for continuous operation in energy recovery, recycling, or high-throughput pre-treatment lines.
