In this case problem was, Cement Mill was not performing as per its design parameters. It was a Vertical Roller Mill is designed for rated capacity 215 TPH but its
WhatsApp: +86 18203695377Another difference between ball mills and attritor mills is the milling atmosphere. In ball mills, the materials to be ground are placed in a container that is filled with air or an inert gas. On the other hand, attritor mills are operated under a controlled atmosphere. The materials are placed in the mill along with the grinding media and a ...
WhatsApp: +86 18203695377For the cement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials.
WhatsApp: +86 18203695377Ball mill machine has always been the main grinding equipment in wet cement production. In the early years, the rod mill was first used in cement raw meal grinding, which increased the output of the grinding section by 31%, saved energy by 27%, and reduced the consumption of grinding media by 47%.
WhatsApp: +86 18203695377One of the advantages of a rod mill is that it can handle a higher capacity than a ball mill of the same size. Additionally, the grinding medium in a rod mill is more uniform than that in a ball mill, and this can be beneficial for certain materials. Rod mills are also relatively lowmaintenance, making them a costeffective option for many ...
