Iron equipment for manganese ore mining, which used to the largest number of iron ore and iron ore crusher crusher. Mixing mill is the use of stirring device makes the motion of grinding media and impact, shear, grinding effect, thus the crushing equipment. Conventional mill is on the cylinder motion to drive the motion of grinding medium stirring mill, power input directly mixing mechanism for rotating, makes the movement of grinding medium and the crushed material, so the energy efficiency is higher than that of the conventional mill. Classification of stirring mill are as follows: (1) according to the way of placement simplified. Divided into vertical stirred mill and a horizontal stirring mill. (2) according to the working mode. Consists of intermittent, cyclic and continuous stirring mill. According to the structure of the form (3). Divided into disc, rod type, screw type and ring type stirring mill. (4) according to the working environment. Is divided into dry and Wet Stirred mill. The structure and characteristics of stirred mill: mixing mill is mainly composed of a filling of grinding cylinder grinding medium and a rotating stirrer (stirring device) form. Because the grinding media initially used is glass sand, therefore sometimes called sand mill. Stirring mill through a stirring shaft rotation, stirred grinding media impact (grinding media asked the mutual impact force and impact force to the medium stirring device) and shear (shear force produced rotating grinding medium) and friction (the friction force between grinding media and materials) function makes the material superfine crushing, mixing and dispersion. Grinding speed mixing by centrifugal force and rotating radius limits. The circumferential speed of stirrer under normal circumstances is about 4 ~ 20 m / s. Grinding of medium generally spherical medium, type of hardness than the best grinding materials is greater than 3, to increase the grinding strength, improve the efficiency of crushing. Medium stirring mill has vertical and horizontal. Vertical agitate mill stirrer shapes are mainly perforated disc type, shaft disc type and radiation shaft type.
