Multifunctional wet ultrafine grinding device

Abstract

The invention provides a multifunctional wet ultrafine grinding device. The multifunctional wet ultrafine grinding device comprises a transmission device, a rack, a stirring shaft and a stirring barrel, wherein the stirring barrel is arranged below the rack; the transmission device is fixedly connected to the upper part of the rack; and the top end of the stirring shaft is connected with the transmission device and extends into the stirring barrel, the stirring shaft comprises an upper section and a lower section, a scrubbing section stirring shaft of the upper section and an ultrafine grinding section stirring shaft of the lower section are arranged in an inner and outer double-layer jacket manner, the scrubbing section stirring shaft is provided with a scrubbing impeller along the radial direction of the stirring barrel, and the ultrafine grinding section stirring shaft is provided with an ultrafine grinding impeller along the radial direction of the stirring barrel. The multifunctional wet ultrafine grinding device is a multifunctional vertical stirring mill, has ultrafine grinding and scrubbing functions at the same time, can achieve ultrafine grinding and scrubbing of powder at a time, and is small in particle sizes of products and good in dissociation effect, and convenient and efficient wet ultrafine grinding equipment is provided for mineral separation of refractory minerals.

Description

technical field [0001] The invention belongs to the technical field of ultrafine grinding devices, and relates to an ultrafine grinding device, in particular to a wet ultrafine grinding device, in particular to a multifunctional wet ultrafine grinding device. Background technique [0002] Grinding is one of the most critical processes in the beneficiation industry and a necessary prerequisite for mineral separation. In recent years, with the increasing consumption of domestic high-quality mineral resources, there are more and more refractory ores with low grade, poor quality and fine intercalation characteristics, and ultra-fine grinding is the best way to realize low-grade, fine intercalation characteristics and other refractory ores. One of the important means of beneficiation and separation. At present, the powder wet ultrafine grinding equipment mainly includes stirring mill, ball mill, sand mill, vibration mill and so on. [0003] Taking the stirring mill as an exampl...
