Vertical stirred mill refers to the mixing mill with the shell placed in the horizontal plane. The basic components contains a cylinder, a stirred device, a transmission device and a frame. Transmission device will transfer kinetic energy of the motor to the stirring device so as to make the rotation, and then the revolving stirring device drives the grinding media and material of the cylinder body to make the multi-layered rotation and displacement movement, therefore it will achieve the grinding, extrusion, collision, kneading and shearing effect of grinding media and material and then achieve the grinding and peeling mineral effect. Domestic and foreign researchers get a great achievement on the development of new type vertical wet stirred mill.
Combining the situation that less study on improving the energy utilization rate and optimum technology of different industrial mineral grinding, the domestic experts design a kind of superfine stirring grinding device called the vertical spiral rod type agitating mill after analyzing the advantages and disadvantages of the four superfine stirring grinding including tower mill, sand mill, rod type agitating mill and ring gap type stirring mill. The material of cylinder body device use alloy steel, stainless steel, polyurethane with a shape design of the special structure. The grinding process use a diameter of Ф1~10mm or finer grinding media with a suitable speed of 3~6m/s, which has the property of high energy utilization rate, convenient operation and maintenance. a tower mill and vertical sand mill are the widely used and typical vertical wet stirred mill.
In recent years, with the rapid development of domestic vertical sand mill, the overall design of equipment tends to be advanced and modularized, and the large scale equipment is also gradually mature, which is applied to the million tons calcium carbonate production line with the granularity requirements of d97≤5μm. Domestic scholars mainly focus on the structural optimization and improvement of vertical sand mill.
Zhengzhou Mining Machinery Co., Ltd. seize the opportunity, invest a lot of research funding, establish a prototype laboratory, put into a lot of manpower and material resources to optimization of the vertical sand mill development. after optimization design, the motor power consumption reduce to around half of the original, which saving 50% compared withthe same type of product model in the market.
