MINERAL FEED ADDITIVE AND FEED ADDITIVE PRODUCTION METHOD Russian patent published in 2001 - IPC

FIELD: feed production. SUBSTANCE: mineral feed additive contains 60-80 wt. % of natural fractionated zeolite and 20-40 wt. % of ultradispersed pure mineral aspirated in the process of treatment of basic raw material - zeolite. Method involves grinding natural zeolite and performing pneumatic classification in aspirating equipment; cleaning aspirated air and exhaust from pneumatic classifier with hose-type filters to release pure ultradispersed mineral; mixing zeolite fraction by fraction in hermetically sealed mixer with ultradispersed mineral in mentioned ratio; exposing obtained mixture to electric field with intensity of 1-50 V/mm to obtain ready product. EFFECT: reduced production cost and provision for producing high-quality feed additive. 3 cl, 1 ex
