Steel slag can be used in construction, highway, railway construction, etc., especially the steel slag powder after crushing and grinding has better performance. According to different production processes, the common grinding equipment on the market at present are vertical roller mills and ball mills. Although both can be used to grind steel slag, in actual production, the difference is still relatively large. So for steel slag grinding, is a vertical roller mill or a ball mill more suitable?

The vertical roller mill is a vertical structure. During operation, the grinding rollers and grinding table grind the material under the action of the centrifugal force of the equipment rotation, so as to achieve the purpose of material crushing; The horizontal grinding table and the conical grinding roller of the vertical roller mill ensure that the material can form a stable material bed, and the energy consumption is low. Generally, the power consumption per machine does not exceed 30Kwh; and the particle size of the finished product produced by the vertical roller mill machine can be in the range of 200-400 mesh. It can be adjusted arbitrarily inside, and some materials can reach thousands of meshes.
The ball grinding mill is a horizontal structure. During operation, it mainly relies on the impact grinding and peeling of the grinding medium steel ball and the material to achieve the crushing of the material. The energy consumption of the ball mill is relatively high. According to statistics, the power consumption per ton of cement produced is not less than 70 kWh, and the finished product is 0.075-0.89mm.
When processing steel slag, when the specific surfa ce area of the vertical mill reaches 4500cm2/g, the average grinding capacity of each steel slag vertical mill is maintained at 90t/h. If a ball mill is selected, at least 6 sets of ball mill systems are required.
The above is the difference between vertical roller mill and ball mill when processing steel slag. When grinding steel slag, users can choose according to different requirements of steel slag processing technology, system power consumption and finished product particle size.
