The ball mill must be shut down separately. All equipment shutdowns are performed locally or from the MCC located in the mill control room.
ادامه مطلبVertical cement mill has high grinding efficiency and low power consumption (20 – 30 less than ball mill). The granularity of the feeding material is larger(VRM cement mill is 80mm-120mm, cement ball mill is less than or equal to 30mm). Cement vertical mill occupies less space and saves 30 of construction cost.
ادامه مطلبOne cement factory in China purchased GRMK53.41 cement vertical mill from CHAENG in 2012. This vertical mill is the largest cement vertical mill in China, adopting new efficient powder separator, easy to operate and operating stably. Its designed output is 220t/h, and the actual output is up to 260t/h.
ادامه مطلبThe difference between ball mill and vertical mill in cement grinding Over the last three decades the vertical roller mill has become the preferred ball mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system.
