220V/380V Scrap Can Shredder Machine Aluminum Door And Window Scrap Aluminum Sheet Shredder

The scrap aluminum shredder is a specialized crushing machine designed for processing various types of scrap aluminum products. Taking into account the characteristics of aluminum—soft texture, high ductility, and ease of deformation—it employs a dual-shaft shredding structure featuring "low speed and high torque."

• Specialized shredding design for aluminum products: Unlike shredders for mixed metals, the blade hardness and cutting angle are optimized for aluminum's ductility—the hardness is lower than that of steel shredder blades (to prevent excessive shredding and waste of aluminum shavings), and the cutting edge forms a 30° sharp angle (for precise cutting along aluminum product seams).
• Low loss and high recovery rate: Aluminum is prone to "cold welding" (aluminum shavings sticking together into blocks) during crushing. The equipment controls this through a precise 1-2mm gap between the blade shafts, combined with an anti-adhesive coating on the blade surface, resulting in smooth edges on the crushed aluminum blocks with no fine aluminum powder, achieving a metal recovery rate of over 99%.
• Strong energy efficiency: The crushing resistance of aluminum is only 1/5 that of steel, and the motor power of the equipment is 40% lower than that of similarly specified metal shredders.
• Oxidation prevention and cleanliness control: All components within the equipment that come into contact with aluminum (such as the feed hopper and discharge guide plates) are made of stainless steel and are equipped with compressed air blowing devices to continuously clean residual aluminum shavings from the blades during the crushing process, preventing the shavings from oxidizing and turning black in the air.
• Modular Compatible Design: Compatible with dedicated aluminum product sorting lines, the discharge port is equipped with a magnetic iron remover (to remove mixed iron impurities) and a density screening plate (to separate aluminum from plastic components, such as plastic lids from aluminum beverage cans).

• Recycling in the aluminum processing industry: Scrap aluminum from aluminum profile factories and scrap aluminum castings can be shredded and directly added as scrap material to the melting furnace.
• Recycling of aluminum packaging products: For scrap aluminum beverage cans, aluminum foil packaging, etc., after shredding and compression, they can be used as raw materials for aluminum foil recycling.
• Processing of construction aluminum waste: Aluminum alloy doors and windows, and curtain wall aluminum profiles generated during demolition can be shredded to separate aluminum frames from glass and rubber seals.
• Recycling of daily-use aluminum products: Scrap aluminum pots, pans, and other daily-use items can be shredded and used as casting raw materials to produce small aluminum products (such as hardware components and toy parts).
