Recognize important considerations in ball mill selection Reading & Lecture In ball mills, steel balls or hard pebbles to break particle based on impact and attrition A rotating mill charged with media and ore is lifted against the inside perimeter Some of the media falls and impacts the ore particles at the bottom of the mill

Mills with as many as four chambers, allowing a tight segregation of media sizes, were once used, but this is now becoming rare Alternatives to multi-chamber mills are: pairs of mills, run in tandem, charged with different-sized media use of alternative technology (see Roll-presses below) to crush the clinker prior to fine-grinding in a ball .

This is a dominant way that the ball mill mill shell) is not yet active and the avalanching segregation which grinds fine particl The fine material to be ground typically fills a is prevalent at low speed (and leads to finer material in the middle) reasonable fraction (70–100%) of the pore space between balls and has been inhibited

ball mill grinding media segregation fousw - aiasoin Ball Mills Our combined experience in ball mill design and process equipment development totals more than 60 years and allows us to put a unique spin on steel and lined mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back .

Ball mills are one of the many mixing vessels used in a mineral processing industry During grinding, the mill’s efficiency depends on particle presentation to the grinding media and the adequate utilisation of the applied forces to effect breakage of particles (ore) , observed to be affected by both the charge system used and segregation .

As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate The risk of underloading or overloading the mill is an additional factor A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
