A comminuting apparatus has a housing and a crushing area. The housing includes left and right bearing plates, left and right reinforcing, bearing and holdback plates, each with clearing and crushing prongs. The crushing un it includes left and right crushing shafts which are rotationally supported by the housing are interconnected to rotate in opposite directions, synchronously. Each crushing shaft includes a number of radially-extending tool carries having tool heads which carry clearing devices and front and rear wear inserts, in seats within the tool heads. The crushing unit can be configured to provide cleari ng spacing between adjacent clearing devices of adjacent tool carriers, or to provide an overlap thereof. The clearing and crushing prongs are arranged between each of the tool carriers. An intermediate crushing area is formed between t he left anti right crushing shafts. The tool carriers can include relatively hi gh and low tool heads to provide differing peripheral rates of rotation for the too ls which define inner and outer spheres of actions.
