A series of Primary Hook Shredder?had been extensively used in the Waste-To-Energy (WTE) plants, for size reduction of municipal wastes before incineration, in recycling plants for sorting of metals, inorganic solids, combustibles, and etc.

Hydraulic driven hook / primary?shredder?feature in low speed and high torque, and have advantages in high throughout and excellent suitability for various wastes.

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.

Primary Hook Shredder Features

1. Combines up to 500 kW total power to process bulky, compacted, or fibrous waste, ensuring continuous operation without stalling.

2. Blade gap adjustable between 50–200 mm, allowing optimization for different material types and downstream requirements.

3. Cutting hooks and rotor shafts made from hardened alloy steel, achieving up to 10,000 operating hours under typical industrial waste conditions.

4. Individual hook and rotor modules can be replaced within 2–3 hours, minimizing downtime.

5. PLC-controlled forward-reverse operation, overload protection, and jam detection reduce unplanned shutdowns and operator risk.

Primary Hook Shredder Applications

1. Municipal Solid Waste Pre-Processing: High-torque hooks shred bulky household and commercial waste, producing uniform pieces that improve sorting efficiency and reduce clogging in conveyors and separators.

2. Industrial Waste Reduction: Adjustable blades and robust rotor design handle plastics, rubber, and compacted industrial materials, reducing storage and transport costs while preparing waste for recycling or incineration.

3. Bulky Waste Handling: Efficiently breaks down large items such as furniture, packaging, and appliances, facilitating further processing or volume reduction for disposal.

4. Waste-to-Energy Feedstock Preparation: Produces consistent particle sizes (50–200 mm) suitable for rotary kilns, gasifiers, or fluidized bed systems, enhancing combustion efficiency and stable energy output.

5. Material Recovery Facilities (MRF): Prepares mixed waste streams for downstream sorting, increasing throughput and reducing contamination rates.
