The Bulk Density Tester, Scott Volumeter, is described in USP Chapter Method 2 is designed for measuring the bulk density of fine powder and similar products. This Apparatus PEP-S-304 is used to determine apparent density of microcrystalline cellulose. The upper funnel contains a 1018 mesh wire support and uses a cylindrical or square 25.00ml 35.00ml+- 0.05ml stainless steel density cup.

The ball mill is used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out either wet or dry but the former is performed at low speed. Blending of explosives is an example of an application for rubber balls. For systems with multiple components, ball milling has been shown to be effective in increasing solid-state chemical reactivity. Additionally, ball milling has been shown effective for production of amorphous materials.
