The capacity not only determines the mill equipment size, but also dictates how to operate the mill, whether continuous or batch operation is required, and whether the process can be performed in-house or if a tolling service is a better option. The required product size is an important grinding cost factor, especially for fine-size grinding.

A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for single-stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits.

Therefore, the basic cost of the conical bottom silo is more than 40% higher than that of the flat bottom silo with the same capacity. Conclusion. From the above analysis, it can be seen that when the steel silo has a large diameter and capacity, the different selection of the silo type could result in obvious construction cost difference.
