FIELD: grinding equipment used in agriculture, chemical, construction and other branches of industry. SUBSTANCE: milling member has hollow metal casing made in the form of body of rotation. Insert positioned within cavity of metal casing is made in the form of piezo element of quartz plate withstanding impact acceleration of up to 50 g. Quartz plate is positioned on two electrodes mounted on board and connected to amplifier. Annular groove on outer surface of milling body casing is adapted for receiving antenna whose input end is extending through opening in casing of milling body and is connected to additional amplifier. Milling body is provided with independent power member. EFFECT: increased efficiency by providing optimum mode of operation, reduced power consumption and improved quality of ready ground product. 2 dwg
