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’.
The 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.
A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.
The sand washer is a kind of highly efficient sand washing plant, taking the advanced techniques and the domestic physical conditions together into consideration.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
Ceramic sand kiln is one kind of calcining kilns which is a rotary cylinder machine used for calcining all types of materials.
Raymond mill adopts advanced structure of the same types of products in domestic and foreign market and is upgraded and improved on the basis of traditional Raymond mill.
The following equation is used todeterminethepowerthatwet grinding overflow ball millsshoulddraw. Formillslarger than 3.3 meters (10 feet) diameter inside liners, the top size of theballsused affects thepower drawnby themill. This is called theball size factorS.
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.

Mill Power Draw(Bond Method) Based on a large number of observations,power drawwas determined to be: Directly proportional to themilllength; A function ofmill speed; A function of the total mass of the grinding media and rock charge; A function of the feed characteristics; A function of …
In terms of supporting data, total mass content,ballfilling, slurry density, load orientation,power draw, and material transport through themillwere measured under various conditions.
CalculatingPower Drawwhen sizingBall MillsGrinding I believe that as circulating load ina ball millincreases beyond a critical point themill power drawbegins to fall so there is an adverse effect on grinding efficiency (apart from the obvious physical problems it causes like high scats rates, balls discharged frommill, sumps overflowing, cyclones clogging up etc.).
Calculation of thepower drawof dry multi-compartmentball millsMay 6, 2004 In this paper, a new approach for the calculation of thepower drawof cement grindingball millsis proposed. For this purpose, cement grinding circuit data including the operational and design parameters were collected from 14 industrialball mills, ranging in ...
