The original cone mill was invented by Quadro ® in 1976. It consists of a cone-shaped mill screen with an impeller that is vertically mounted and driven from the top by a direct drive belt. The hand-fed product falls through the infeed into the conical screen chamber where the rotating impeller imparts a vortex flow pattern to the incoming ...

Micro ball-end milling is an efficient method for the fabrication of micro lens array molds. However, it is difficult to meet the machining quality of micro dimple molds due to the wear and breakage of the milling cutter, which presents large challenges for designing geometric structure and edge strength of micro ball-end mills. In this study, a …

Figure 2.27. Cut-away view of the Hardinge conical ball mill showing how energy is proportioned to the work required is about 0.3 kg/Mg of material for dry grinding, and 1-1.5 kg/Mg for wet grinding. The normal charge of balls is about 5 Mg/m3. In small mills where very fine grinding is required, pebbles are often used in place of balls.

The operating principle of autogenous mill is essentially the same as that of ball mill. Most remarkably, the crude ore from stope or the coarsely crushed ore can be directly fed into the grinding mill. The autogenous mill will grind the material to the extent that the content of the particles with particle size <0.074 mm accounts for 20–50% ...
