Eccentric stirring ball mill

Abstract

The invention belongs to the technical field of milling equipment and particularly relates to an eccentric stirring ball mill. The ball mill comprises a rack, wherein first bearing holders are symmetrically arranged on brackets at two ends of the rack in the horizontal direction, a main shaft is arranged in first bearings in the two first bearing holders; one end of the main shaft extends out of one first bearing holder and is driven to rotate through a belt wheel; the belt wheel is connected with a motor; a cylinder body is arranged on the main shaft through a pair of eccentric blocks and second bearings; the main shaft is fixedly connected into the eccentric blocks; the axis of the main shaft is in parallel to but not overlapped with the central lines of the eccentric blocks; the eccentric blocks are fixedly connected onto the inner rings of the second bearings; the second bearings are arranged at two ends of the cylinder body; the central line of the cylinder body is overlapped with those of the eccentric blocks; a stirrer is fixedly connected onto the part, in the cylinder body, of the main shaft. The size and weight of the eccentric stirring ball mill are reduced, and the manufacturing and mounting costs are greatly lowered; product grains produced by the ball mill are good in shape and strong in adaptability; the speed and efficiency are high and the energy saving effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of milling equipment, and in particular relates to an eccentric stirring ball mill. Background technique [0002] In recent years, the great strides in the development of the powder industry have provided opportunities and challenges for milling equipment. At present, my country's milling equipment mainly includes ball mills, Raymond mills, stirring mills, vibration mills, vertical mills, and ring roller mills, but mill equipment with low technical content still occupies the main market share of the powder industry. Large size, high cost, high energy consumption, high pollution, and the shape of the finished product of the vertical mill is not ideal. The investment in grinding in the concentrator accounts for more than 30%, and the power consumption accounts for about 40%. Therefore, it is of great significance to improve the grinding efficiency of the grinding equipment. Contents of the invention [0003...
