Nowadays, with the rapid development of the grinding industry, it is no stranger to the mining industry. It is a grinding processing equipment with simple structure, reliable operation and low failure rate. It is very suitable for the processing and production of blast furnace ash. At the same time, in addition to processing blast furnace ash, it can also be applied to the processing of a variety of materials. Then, let's learn how much fineness the lower blast furnace ash grinder can achieve and how to improve the fineness of the grinding equipment?

We should know that when the rotation speed of the ultra blast furnace ash mill is too high or too low, the coarse powder or fine powder will be transmitted to the powder outlet prematurely, which will affect the fineness of the material. Therefore, we need to adjust the rotation speed artificially by controlling the motor current of the blast furnace ash mill. This equipment is used for grinding blast furnace ash, and its finished products can reach 200, 500, 800, 1000, etc. it is found that the powder selection technology of this equipment is good in use.

In operation, the fan speed of the blast furnace ash mill determines the size of the wind. When the grinding material is light, if the wind is too strong, some powder that has not been completely ground will be blown into the powder collector; Conversely, if the proportion of materials is large and the wind force is too small, it will also affect the discharge, so it is also important to control the fan speed of the ultra-fine mill; During the normal operation of the mill, the grinding roller and the grinding ring will not be in direct contact. With the increase of the use time, the wear degree of the grinding roller and the grinding ring will also increase. If the materials are not fully ground, the fineness of the finished products will be affected and the coarse particles will increase.

To know how to improve the fineness of the blast furnace ash mill, we need to understand the following points: 1. The material problem of raw material hardness. Different materials have different hardness. This fixed factor determines that materials should be reasonably configured in crushing and grinding production. Under the condition that the fineness of the required materials is consistent, the materials with uniform size and relatively uniform shape are reasonably proportioned and sent to the crushing chamber for grinding production. If mixed for grinding, the production will be unstable, which will easily lead to uneven discharge fineness and different properties of finished powder and raw materials.

2. Improve the grinding particle size of materials in the blast furnace ash mill. Since different materials can be processed with different particle sizes, it is necessary to know the minimum value of materials that can be broken. It is not allowed to blindly ignore the properties of materials to meet the grinding requirements. In this way, the internal components of the blast furnace ash mill will also be damaged, the consumption of vulnerable parts will be large, the replacement cycle will be short, and the fineness of discharge will not be guaranteed.

3. Selection of screening device of blast furnace ash mill: the finished grinding products need to be screened by the screening device during the collection and concentration process. If they do not meet the fineness requirements, the secondary grinding process will be carried out. Therefore, the selection of screening equipment is the key to control the fineness of grinding.
