1.Description
GNJ thickener is a large-scale High-rate thickener that we have developed by absorbing international updated technology and adopting peripheral rubber-tire drive, with structure of central lifting rake. It has a simple structure and big torque; mainly used to concentration of finished ores and ore tailings; adopting leading automatic control technique ensures random checking of the running resistance and various parameters, adjusting running status and achieving stepless speed control (hydraulic or frequency control), so as to meet pulp density operation of various specific gravity and concentration.
