Read OnThe sample below 3350 μm (d 80 = 2100 μm) was ground in the laboratory scale stirred mill and ball mill. The d 80 sizes of the products at the end of grinding periods of 0.25, 0.50, 1 and 4 min in the stirred mill were determined as 190, 102, 78 and 28 μm, respectively. For this purpose, the stirred mill was used at a stirring speed of 360 ...

Read OnIn this study, we used a planetary ball millin laboratory scale. The powders dis-tribution, the balls distribution, and the wear were modeled using DEM. The simulations of dry mill were conducted by using a standard coefficient of restitu-tion of 0.3 and a friction coefficient of 0.75 (ball-ball and ball-liner collisions) [20].

Read OnThe vertical milling machine is a precision tool used for shaping and fabrication by the removal of stock typically from metallic work pieces. Plastics and other materials can also be machined on the mill depending upon tooling and material. Mill controls may be manually operated, computer numerical controlled (CNC), or a combination of both.

Read OnThe aim of this study was to investigate the grindability of solid fossil fuels from a thermal power plant by using a vertical stirred mill and conventional ball mill. The solid fossil fuel sample was obtained from the Zonguldak Catalagzi thermal power plant in Turkey. The sample below 3350 μm (d80 = 2100 μm) was ground in the laboratory scale stirred mill and ball mill.
