ASTAR’s single-shaft shredder with push drawer is a robust, yet versatile size-reduction equipment capable of shredding a large range of material including plastics, wood, paper, textiles, tires, packaging, biomass, and more. These machines are specially designed to shred thick materials that are highly resistant to cutting such as plastic blocks and sheets, plastic buckets and drums, various types of timber, extruded polymer pipes, etc. You will find our heavy-duty shredders being commissioned in tough industries such as in municipal solid waste processing plants, material recovery facilities (MRFs), and recycling facilities dealing with commercial and industrial waste.

 

Our single-shaft shredders use unique, square knives that are bolted securely onto a large, closed rotor in a staggered array. As the square rotor knives are mounted with the corners protruding, jagged-teeth knives are mounted within the cutting chamber that act as the stationary knives. Unlike granulators that spin at high speeds, single-shaft shredders are relatively quiet, slow cutting machines that spin between 60-100 rotations per minute. As material is fed into the shredder, a hydraulic assisted drawer pushes the material against the rotor where it will be continuously cut until it reaches the desired size as designated by a screen filter that is fitted beneath the cutting chamber; The material will continue to be shredded until it is small enough to fall through this screen filter.

 

As our single-shaft shredders are often times placed in front of the most demanding jobs, the frame and structure of our shredders use high-thickness sheets and tubular. The square knives are treatment strengthened and use only the highest quality SKD11 steel (D2 equivalent) to ensure against dulling. Depending the capacity you require, we offer a variety of standard single-shaft shredders for your choosing.

All ASTAR’s recycling machinery are made with usability in mind, our single-shaft shredders are no different. You will find our single-shaft shredders to offer motorized access to the cutting chamber as well as motor assisted screen changes as standard equipment.
