The main function of the equipment is to squeeze the bulk materials and large-diameter drum metal materials that are not convenient for transportation through the shear of the shredder, and shred them into sheets that meet the requirements. The main structure of the double-shaft shredder is a feed hopper, a knife roller, a driving device, a bearing, a hydraulic system, and an electric control box system. Working principle: All kinds of waste materials enter the shredding chamber through the feeding hopper. The double-knife rollers do relative rotation to shred and cut the materials, and then the materials are discharged from the shredder to achieve the shredding of large pieces of materials. Lhodpevn D I Nsfx Amtoi Applicable materials and fields Double shaft shredder is one of ethential equipment for waste recycling in following fields and materials: +Bulky Waste: Sofa,Mattress,Chair, Funiture,Windows,etc +Industrial Waste: Textiles,Leather,Rubbers, Leathers ,General industrial waste,etc +Hazardous Solid waste: Medical waste,Paint sludge,Radioactive waste,Hazardous waste oil drum,Jumbo bag,etc +Paper waste: Carton,Cardboard,Book,Newspaper,Document,Brochure,Packaging paper,etc +Garden waste: Branch, Wood pallet, Trunks, Boards,etc +Domestic waste +Biomass straw: Straw, Bamboo, Corn, Sorghum straw, Bean straw, Fruit shell, Palm shell, etc +Scrap metal: Car Shell, Aluminum casting, Household appliances, Scrap light metal,Automobile hub,etc +Paper mill waste: Paper mill slag, Paper mill rope, Paper mill offcut,etc +Wood pallet, scrap furniture, waste chair, tree roots recycling, etc. Double shaft shredder main body: The main body is welded with excellent steel plate to ensure the stability of the equipment under heavy load for a long time. Bearing: The bearing seat is split and easy to disassemble, and the movable knife, fixed knife, bearing and other parts can be quickly removed, and it is easy to maintain and replace the knife. The sealing structure can avoid the contact of broken materials and grease, and can also protect bearings and gears when handling liquid materials.
