Abstract

The invention relates to a three-screw planetary transmission vertical medium stirring mill, and belongs to the field of ore dressing and grinding fragmentation. The three-screw planetary transmission vertical medium stirring mill comprises a motor, a motor support, an outer tooth ring, a plant rack, a gear box, a shaft coupling I, a material outlet, a cylindrical shell, stirrers, a material return tube, a cylindrical shell liner plate, a material inlet tube, a roller needle, a planetary gear, a sun gear, a short shaft and a shaft coupling II. The three helical stirrers are ingeniously combined with planetary transmission, and the advantages of the planetary transmission are fully used to make a transmission structure compact, greatly improve the transmission efficiency and the power density and realize a direct deceleration effect; and the revolution and rotation motion of the three helical stirs increases the motion complexity of materials in the cylindrical shell and effectively reduces the central dead zone phenomenon induced by material centrifugation, so the effective grinding area in the mill is increased. The three-screw planetary transmission vertical medium stirring mill has the advantages of superior grinding mechanism, reliable transmission, compact structure, low energy consumption, high efficiency, small occupied area, wide application range, and simple and convenient use and maintenance.

Description

technical field [0001] The invention relates to a three-screw planetary transmission vertical medium agitation mill, which belongs to the technical field of ore dressing, grinding and crushing. The invention can be applied to many industries such as metal, paint, mine, dyestuff, smelting, and chemical industry. Background technique [0002] With the large demand for fine grinding and ultra-fine grinding in the industry, more and more attention has been paid to the media stirred mill, and more and more researches have been done on the media stirred mill. Compared with the traditional ball mill, the media agitated mill has the advantages of high efficiency and energy saving, superior grinding mechanism, simple structure, convenient installation and maintenance, and effective prevention of over-grinding. [0003] The medium-stirred mill is generally composed of a cylinder, agitator, support device, drive and transmission device, classifying device and so on. The working princi...
