| 1 | Single-Shaft Shredder | A rotating rotor works against a screen and hydraulic pusher to reduce material to a controlled size. | Plastic lumps, film, wood, packaging waste, and production scrap. | Plastic recycling, wood-waste processing, and preparation of materials for further sorting or granulation. | Screen openings influence output size; inspect material thickness, toughness, and the need for a consistent product. |
| 2 | Dual-Shaft Shredder | Two counter-rotating shafts use intermeshing cutters to tear and shear bulky material. | Mixed municipal solid waste, bulky waste, tires, drums, and selected industrial scrap. | Waste volume reduction, pre-shredding, and preparation of mixed or bulky feed for downstream processing. | Usually produces a coarse, less uniform output; confirm feed restrictions and the required downstream size. |
| 3 | Four-Shaft Shredder | Multiple cutter shafts shear material, with sizing screens used in some designs to control discharge size. | Plastics, electronic scrap, light metal scrap, and mixed industrial waste. | Recycling lines that need staged cutting and a more controlled output than coarse pre-shredding. | Screen and cutter configuration should match the target particle size and the material’s metal content. |
| 4 | Hammer Mill | High-speed hammers impact and break material; screens help determine the discharged particle size. | Wood waste, selected biomass, brittle plastics, and other materials suited to impact reduction. | Biomass preparation, wood-waste processing, and size reduction of suitable brittle feedstocks. | Check moisture, abrasiveness, and the risk of sparks or dust; unsuitable feed can increase wear and operating risks. |
| 5 | Jaw Crusher | Material is compressed between a fixed jaw and a moving jaw. | Concrete, masonry, bricks, and other hard, brittle construction and demolition debris. | Construction and demolition recycling, where large rubble is reduced before screening or secondary crushing. | Best suited to hard, brittle feed; remove reinforcing steel and other uncrushable items as required by the system. |
| 6 | Impact Crusher | Rotors or impact elements accelerate material against impact surfaces to break it by impact. | Concrete, asphalt, masonry, and other mineral construction waste. | Secondary reduction and aggregate production in construction and demolition recycling operations. | Feed hardness, abrasiveness, and metal contamination affect wear; a suitable separation process may be needed. |
| 7 | Roll Crusher | One or more rotating rolls compress or shear material through a controlled gap. | Relatively brittle materials, selected mineral waste, and some dry process residues. | Controlled size reduction where a comparatively uniform product and limited fines are important. | Confirm that the material is suitable for compression or shear and that the roll gap meets the output requirement. |
| 8 | Plastic Granulator | Rotating knives cut plastic against stationary knives; a screen controls the granule size. | Plastic sprues, runners, rejected molded parts, and pre-shredded plastic. | In-house plastics recycling and preparation of plastic regrind for subsequent processing. | Match rotor and screen configuration to polymer type, part thickness, and the desired regrind size. |
| 9 | Tire Shredder | Heavy-duty cutters shear whole or sectioned tires into smaller pieces, often in multiple processing stages. | End-of-life tires, subject to the machine’s accepted tire sizes and feed requirements. | Tire recycling and preparation of tire-derived material for further separation or processing. | Steel reinforcement and tire construction create substantial wear; downstream wire and fiber separation may be required. |
| 10 | Mobile Crusher | A crusher mounted on a mobile chassis processes feed on-site; the crushing mechanism may be jaw, impact, or another type. | Concrete, asphalt, masonry, and other suitable construction and demolition materials. | On-site recycling at demolition projects, quarries, and temporary material-processing locations. | Choose the crushing mechanism for the feed and review site access, mobility, dust control, and material-separation needs. |
