Raw mills play a critical role in cement manufacturing. Here are some benefits of using a raw mill in a cement plant: Consistent raw mix quality: Raw mills produce a consistent and homogenous raw mix, which ensures consistent cement quality. Lower energy consumption: Raw mills use less energy compared to traditional ball mills, which …
For the past three decades the vertical roller mill has emerged to be the preferred choice for grinding raw materials. With the grinding capacity of a vertical roller mill and the ability to dry, grind and sort in a single unit, the vertical roller mill offers a definite advantage over the ball mill system [10].
The raw mill model of a company is ATOX50. The grinding condition of this vertical mill is stable since it was put into production in March 2008. By the summer of 2015, in order to meet more stringent environmental emission requirements, electric dust collector at the end of the kiln has been replaced with electric bag compound dust collector.
