Abstract (en)
Provided is a method for replacing a choke ring of a vertical shredder including a feed hopper, a shell, a shredding mechanism, a discharge ring, and a choke ring disposed between the shell and the discharge ring and forming a gap between it and the shredding mechanism, the gap allowing shredded fractions to fall therethrough, the feed hopper, the shell, and the discharge ring forming a hollow space therein, the vertical shredder including a spacer forming an extended space that extends the hollow space along a direction of an axle. The method includes: a clamping pressure reduction step of reducing or releasing clamping pressure between members clamping the spacer; a spacer detachment step of removing the spacer after the clamping pressure reduction step; and a choke ring replacement step of replacing the choke ring by pulling it radially outward using a space ensured by the spacer detachment step.
