Characterization of machines for processing of waste materials

The paper presents the machines for processing of waste materials in agriculture. There are many waste materials from which it is possible by means of suitable machines to obtain the product which can be favourably used. The aim of crushing of waste materials is to reduce their volume and to use them favourably. For crushing small waste wood and branches into matchwood, small tractor-driven machines and electric motor machines are used. Larger machines for the biomass preparation are more capable and more expensive; they have their own drive and a motor output of more than 200 kW.The paper discusses testing of the new crushing machine Terminator 5000S-181024 of Komptech make for different materials to be crushed. The test includes crushing of different types of materials of different densities by means of new crushing rolls. Capacity of the machine and the required split clearance for the individual type of material on the crushing roll are indicated.Further, the Terminator 5000S-181002 and the Crambo 5000 were mutually compared concerning capacity of waste wood crushing.
