Now we much select aBall Millthat willdrawthispower. Theball mill motor power requirementcalculated above as 1400 HP is thepowerthat must be applied at themill drivein order to grind the tonnage of feed from one size distribution. The following shows how the size or select thematching millrequired todrawthispoweris calculated from known tables ‘the old fashion way’.
Chat OnlineThe ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Details+Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
Details+Ceramic sand kiln is one kind of calcining kilns which is a rotary cylinder machine used for calcining all types of materials.
Details+But as themillspeed approaches the critical value more number of balls start to stick on themillshell, the effectiveballmass reduces and thus, themilltends todrawlesspower. In this context, one should realize that the peak of the curve would depend upon friction betweenmillshell and grinding media.

More DetailsIt was reported that fora ball millwith 5 m diameter and 7 m length, thepower drawcan be between 2.5 and 3.5 MW, only 1–5% of this energy uses for the size reduction as an actual duty of milling . Therefore, estimationof power-drawcan be considered as an indicator for amillperformance , , .
