The rasper machine is the ultimate machine for mid-stream grinding and steelseparation. It is specially designed to process pre-shredded tires chips and produce between 12-25 mm (0.5" - 1") wire free rubber mulch. And the rasper can process up to 6 tons of input per hour. The main rotor housing is equipped with replaceable wear plates to increase the durability and longevity of the cutting chamber. Another unique feature of this machine is the ability to turn the knives once before having to send them to be sharpened or replaced, minimizing operating costs.
