The M&J PreShred 6000M is available with 9–16 rotating knives, depending on the required grain size.
The knife has a bigger diameter and 2 x 3 knife tips on each blade, providing a higher capacity.
The rotating knives are 80 mm thick and made of Hardox steel. Versions equipped with 2 shafts, and 9 knives per shaft, produce a coarse grain size. They are ideal for manual picking lines.
The version fitted with 16 knives produces a material < 100 mm, making it ideal as a secondary shredder for use in conjunction with Circulating Fluidized Bed (CFB) incineration or other applications requiring relatively small grain size.
