If the bigger steel balls take a larger proportion, the impact force generated by the steel balls falling causes more damage to the liners and the steel ball consumption is increased. While if smaller steel balls are more than bigger ones, the material gets more buffering effect. And the grinding efficiency is decreased.

Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force.In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear …
The load exerted by grinding balls on lignocellulosic biomass in a vibratory ball mill is significantly larger than the other mill types, resulting in the highest enzymatic hydrolysis yield. The glucose yields achieved were 95.2, 75.2, 61.0, and 52.8%, for vibratory ball mill, tumbler ball mill, jet mill, and centrifugal mill, respectively ...
Predicting Steel Media Consumption Grinding . The Amps in a mill are a derivative of the Kg/KWh, which is the ultimate most important indicator for steel balls consumption When one make the integration of Amps vs time one obtains the kWh, so those parameters are proportional, but also the kWh gives an indication of the mill efficiency The balls coating is an interesting …
For an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill, using the simple expression: where dr represents the diameter of the new make-up balls periodically charged to the mill.
Ball Mill Specifications All-Steel Shells and Heads. Ball-Rod Mills have heavy rolled steel plate shells which are arc welded inside and outside to the steel heads or to rolled steel flanges, depending upon the type of mill.
