Industrial shredder

Essential machinery for material size reduction

We invite you to contact us to discuss your specific needs for a metal shredder machine for sale. Our team of experts is ready to assist you in selecting the best options available.

An industrial shredder is a crucial piece of machinery designed to breakdown materials for purposes such as recycling, reducing volume, and destroying products. They vary significantly in size and configuration based on the type of final particle size required.

These machines generally fall into a few designs categories: low-speed, high-torque shear shredders (available in single, dual, triple, and quad shaft designs), single shaft grinders (with single or dual shaft designs), granulators, knife hogs, raspers, maulers, flails, crackermills, and refining mills. Key components of an industrial shredder include the rotor, counter blades, housing, motor, transmission system, power system, and electrical control system.

Typical materials shredded include tires, metals, construction and demolition debris, wood, plastics, leather, paper, and general waste. These shredders are commonly employed to process materials into smaller pieces for easier separation and transportation, helping manage costs. They are instrumental in the treatment and disposal of municipal solid waste, radioactive waste, medical waste, and even hazardous waste.

Given the varying hardness of different materials, industrial shredder blades are designed accordingly to maximize efficiency and durability.

Industrial shredders can be specified for different applications, equipped with diverse cutting systems such as horizontal shaft design, vertical shaft design, and various shaft configurations (from single to four-shaft systems). These shredders can be either slow or high speed and are not defined by their speed or horsepower alone. Compact, budget-friendly portable shredders are also available, suited for personal or small-scale industrial use.

Highlighting notable examples, the world's largest scrap metal shredder, designed by the Schnitzer Steel Group of Portland, Oregon in 1980, boasts a power of 10,000 hp. The 9,200 hp (6,860 kW) Lynxs system at Sims Metal Management's Newport, Wales facility processes 450 cars per hour via road, rail, and sea access.
