1. Capacity: One of the most important batch mixing system considerations for dry goods is capacity. When working with a ribbon or paddle mixer, the total capacity cannot exceed swept volume (space occupied by the ribbon mixer). Over and under filling can increase the variation in the mix and may also increase the mix time.

As the retention time in ball mills is 20 to 30 times greater than in vertical roller mills, the cement is exposed to the hot gas atmosphere for much longer. In addition, ball mills use much more energy than vertical roller mills in order to grind the same amount of cement, with this additional energy heating the material even further.

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 energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

The principle of the new generation of vertical mill was to direct higher pressure from the grinding element to the material bed using hydraulic systems. From this approach the roller press, CKP (pregrind vertical rollers) and Horomill ™ all developed. Raw milling. The gasswept vertical mill quickly became the raw mill of choice.
