a)Mill Geometryand Speed – Bond (1954) observedgrinding efficiencyto be a function ofball milldiameter, and established empirical relationships for recommended media size andmill speedthat take this factor into account. As well,millswith different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for high reduction ratios, and the …Email:[email protected]

Ball milllinerefficiencybased on liner geometry and its influence on kW-hours/ton, total tons/life cycle, and P80 transfer to cyclones.Ball millgrind is based on different principle; it has some attributes similar to SAGmilloptimization.
High classifyingefficiencymeans that those qualified grains can be discharged timely and efficiently, while low classifyingefficiencymeans that most qualified grains are not discharged and sent to theball millfor re-grinding, which is easy to cause over-grindingand thus affecting the separating effect.
Ball Mill EfficiencyCalculations .Ball Mill Ball millis the key equipment forgrindingafter the crushing process which is widely used in the manufacture industries such as cement silicate new building material refractory material fertilizer ferrous metal nonferrous metal and glass ceramics and can be used for the dry and wetgrindingfor all kinds of ores and other grind able materials
Climax converted 70% of primarymill grindingcapacity to mixed size, rationed charges of 50% 76 mm + 50% 51 mm martensitic alloy steel balls in January, 1981, and plans to complete the conversion to rationed charging of martensitic steel balls whenballhandling and charging modifications in the older part of the plant are complete.
The more control you have over themill, the better yourgrinding efficiencyis likely to be. Ourball millsinclude monitoring systems to continuously measure the material and air temperatures as well as the pressure at themillexit. The venting of themillis adjusted by a damper in the inlet to themillfan.

Rodmillsare less common thanball millsforgrindingminerals. The rods used in themill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater thegrinding efficiency. Autogenousmill.
Dec 26, 2017· Several factors affect theefficiencyof aball millfor cementgrinding. In this article, we shall be looking at some of these factors that have been proven to influencegrinding efficiency:MillGeometry And Speed. According to Bond (1954), thegrinding efficiencyof amilldepends on theball milldiameter, size of the media andmillspeed.
