FIELD: agricultural engineering, in particular, grinding equipment.
SUBSTANCE: knife is manufactured from strip steel by rolling at least one longitudinal edge of steel strip for producing prismatic blade with rounded cutting edge having demanded sharpening angle. Grinder knives are rigidly fixed on rotating drum of grinder or knives may be fixed for rotation thereon. If necessary, dented fluting may be provided on longitudinal edge of knife. At least one prismatic cutting edge has rolled texture extending along at least part of length of longitudinal edge, said texture having prismatic arrangement of rolled surface zones. During operation of grinder, counter knives are inserted into intermediate gap between knives, said counter knives being similar to grinder knives.
EFFECT: prolonged service life, increased flexural and twisting resistance of knives.
