1. A bucket crusher, comprising a box-shaped bucket body defining a loading compartment and an unloading opening, said bucket crusher comprising at least one crusher unit configured to crush sheet material,
said at least one crusher unit comprising:
a cylinder, rotatable about a rotation axis and forming a cylinder wall,
a plurality of crusher teeth connected to the cylinder wall, wherein each crusher tooth of the plurality of crusher teeth extends between a proximal end and a distal end, wherein the proximal end faces the cylinder wall and the distal end is opposite to the cylinder wall, wherein each crusher tooth defines a tooth angular dimension,
wherein the plurality of crusher teeth comprises at least one high crusher tooth and at least one low crusher tooth,
wherein a distance between the cylinder wall and the distal end of the at least one high crusher tooth is greater than the distance between the cylinder wall and the distal end of the at least one low crusher tooth,
wherein the crusher teeth positioned on the cylinder wall define a plurality of axial units of crusher teeth, each said axial unit defined by a plurality of crusher teeth following one another in an angular direction with reference to the rotation axis, wherein an angular distance between each crusher tooth and a previous crusher tooth or a successive crusher tooth is less than the tooth angular dimension, so as to define on the cylinder wall a plurality of empty spaces without crusher teeth, said empty spaces having an angular extension equal to at least one tooth angular dimension and extending along an entire length of the cylinder wall.
