Double Shaft Shredder is a powerful primary shredding machine engineered to process bulky and difficult waste materials into smaller, uniform pieces for efficient recycling. It is widely used for shredding scrap metal, steel drums, waste tires, plastic containers, wood, agricultural waste, and various industrial wastes.

Equipped with two counter-rotating shafts and durable alloy blades, the machine delivers strong tearing and shearing force with high torque and stable performance. This design ensures consistent output size, low noise, and reliable operation even under heavy-duty working conditions. 

Kowloon Machinery is a professional double shaft shredder Manufacturer in China, provides customized shredding solutions based on different material types, capacity requirements, and output sizes to help customers improve productivity and reduce operating costs.

Tire shredder is a low-speed, high-torque twin-shaft machine designed to tear whole tires into rubber chips for recycling. It is a core machine in automatic waste tire recycling systems, designed to efficiently process whole tires, such as truck tires, car tires, and even large OTR tires into uniform tire pieces. The shredded rubber output is ideal for further processing into rubber granules or crumb rubber. The finished products are used to produce reclaimed rubber, modified asphalt, rubber bricks, pyrolysis oil, sealing strips, insulating rubber materials, waterproof materials, drainage pipes, paving of roads and runways, road coverings, TDF, TDA, etc.

Equipped with high-strength alloy steel blades, a robust gearbox system, and intelligent overload protection, the machine can easily cut through steel-belted tires and ensure reliable long-term performance. It delivers powerful tearing, shearing, and cutting performance while maintaining stable and continuous operation under heavy-duty conditions.

Kowloon Machinery provides Complete Automatic Waste Tire Recycling Line, which can process waste tires into rubber granules or rubber powder, the output size can be adjusted according to customer needs.

Our metal shredder is designed to process a wide range of scrap materials, including car bodies, steel drums, paint buckets, home appliances, aluminum cans, iron sheets, and mixed metal waste. With a low-speed, high-torque dual-shaft design, it delivers stable shredding performance and handles both light and heavy scrap efficiently, with capacities ranging from 5 to 30 tons per hour depending on the model. As the core equipment in a complete scrap metal recycling line, this metal shredder prepares materials for magnetic separation, crushing, and sorting, improving recycling efficiency and maximizing material value. The metal shredder is widely used in scrap yards, recycling plants, steel mills, and waste management facilities. As the first key piece of equipment, it is responsible for shredding the bulky scrap metal into suitable sizes that are easy to sort and classify in the subsequent process, and has become an indispensable part of modern scrap metal recycling operations.

Metal Crusher can effectively break large materials into small pieces or particles for subsequent recycling, smelting or reuse. It is driven by a high-speed and high-torque motor, the hammer on the rotor of the crusher hits the metal in the crushing chamber in turn. Under strong impact, the metal is torn, hammered, lumped,  crushed into small particles. The scrap metal hammer crusher can peel off the surface dirt such as rust and paint on the surface of the scrap steel during the crushing process, and then under the action of the magnetic separator, high quality and high purity metal particles can be obtained.

Metal Crusher can break metal scraps like metal barrels, broken bridge aluminum, shredded car, etc. Widely used in steel plants, metal smelters, metal foundries, scrap metal recycling stations, metal recycling resources companies, metal products factories, metal processing plants, automobile manufacturers, other industries and fields.

Raw Material: Plastic, wood, cardboard, aluminum, etc.

Available Blade Materials: D2 / SKD-11 / Cr12Mo1V1 / Cr12MoV / H13 / 55SiCr / 9CrSi / M6V etc.

Single shaft shredder is an efficient industrial machine designed to reduce the size of various waste and recyclable materials. It is widely to recycle solid wastes, such as plastic, wood, rubber, light metal, municipal solid waste, industrial waste, etc. It is an ideal machine for the size reduction of a wide range of different materials, the qualified size will discharge from the screen mesh, the oversize material will be send back for re shredding. The final product size can be adjusted by changing the final product size. It can be used alone or in a recycling line.

Biomass Straw Shredder is an industrial shredding machine designed for efficient processing of agricultural biomass materials such as rice straw, paddy straw, wheat straw, sugarcane bagasse, hay, crop stalks, corn stalks, palm fiber, coconut husk, and other organic waste. The machine reduces bulky biomass materials into smaller and more uniform sizes, making them easier for transportation, storage, composting, biomass fuel production, and further recycling applications.

Equipped with high torque shredding technology and wear-resistant blades, the Biomass Straw Shredder delivers stable performance and continuous operation in biomass recycling plants and agricultural waste processing facilities. The equipment can be integrated into biomass pellet production lines, RDF production factory, livestock forage making system, organic fertilizer plants, and biomass power generation projects.

Kowloon Machinery supply complete biomass straw recycling line with customized solution depend on your requirements. Contact us now for the best solution and price!

Kowloon heavy-duty industrial tub grinder is engineered to maximize volumetric throughput, transforming bulky, irregular wood waste into high-value biomass feedstock or premium mulch. Driven by high-torque power configurations and featuring an extra-wide, deep-flared rotating tub with a disc inlet exceeding 3 meters, the system allows massive tree stumps, roots, branches, forestry residues, and stubborn bark to be directly dumped into the continuous-feed grinding chamber.

Available in both stationary and mobile configurations, our tub grinders deliver a high-capacity processing throughput of 10 to 50 tons per hour (TPH) depending on material density. By integrating advanced knife-cutting technology, this system completely replaces traditional, energy-intensive wood splitting and chipping machines, significantly lowering operational and labor costs. Equipped with a heavy-duty folding hydraulic discharge conveyor for flexible material stockpiling, Kowloon tub grinders are widely utilized in biomass power plants, paper mills, sawdust manufacturing facilities, charcoal processing lines, wood-based panel factories, and commercial wood processing hubs worldwide.
