Suitable grinding equipment is essential. To test materials of a low to medium ou content, the ordinary coffee or attrition mill will suffice. To test materials of a high oil content, it is sometimes necessary to use a small flouring mül, with 6 by 6 inch corrugated rolls running at a differential of 1J^ to 1. These rolls should be corru-

components include grinding rollers, rocker arms, pedestals and spring assemblies. The principle behind this structure was patented in 1970 and is employed for coal grinding mills and mills in the cement and industrial minerals industry. 2, 3, 4 or even 6 grinding roller con-figurations for a single grinding table can be realised.
Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
