Maxicrom®grinding ballYou can grind to the maximum with Maxicrom® grinderball. It revolutionizes coarsegrinding. It is used in the first chamber of rawgrinding millsand cement tubemills. It leads the way in processefficiencyand wears well with little deformation. Fewer top-ups will be needed which makes for less safety risks for ...
Grindingballs were selected as shown in Table 1 for these reasons: firstly, it was observed that only balls smaller than 40 mm may show significant effects of media ongrindingkinetics in small laboratorymills(20 cm diameters or smaller); secondly, to mimic the charge motion in industrialmill, the ratio ofmillcylinder’s diameter to maximumballsize should be at least 6, for instance ...
Also thegrinding efficiencyofball millwill reduce. If the steel balls are too small, even the collision probability is relatively high, but the energy of single steelballis very small, which cannot efficiently grind the ore particles, also leading to the reduction ofgrinding efficiency.

There is no doubt that vertical rollermillsoffer significant advantages overball millsin terms of their energyefficiency. The specific energy consumption of aball millis greater than a vertical rollermill(VRM) that performs the same operations by a factor of between 1.5 and 2, depending on the degree of optimization of theball mill.

1 Calculation ofball millcapacity. The production capacity of theball millis determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of theball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...

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.
Ball Millsare generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonableefficiencywithball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into themillto be reduced.
