It is shown that mechanical treatment in a ball mill leads to a decrease in the defects level, an increase in the Curie point and a demagnetizing factor of ferrite ceramics. The growth of the demagnetizing factor is associated with an increase in the porosity of ferrite ceramics samples pre grinded in ball.

An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a khd humboldt wedag ball mill on grinding and classification performance of a hybrid high pressure grinding roll hpgrmulticompartment ball mill cement grinding circuit mass balance.
The ball millliner and grinding medium are directly contacting with the ore particles which affects the movement state of the grinding media and the ore particles and affects the grinding effect. Among the influence of the ball mill lining on the grinding effect the most important one is the influence of the material and the liner’s shape on grinding effect.
The important of crushing your ore and rock fine and properly is often forgotten. The finer you crush, the higher your ball mill tonnage and capacity will be. The effect of ball mill feed size and how it affects circuit throughput can be hard to estimate. Here we described a method of designing a crushing plant using power drawn and power rate to define reduction ratios in each stage of.
Ball mill is the key equipment for grinding after the crush process, and it 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 ball mill also can be used for the dry and wet grinding for all kinds of ores and other grind able materials.

Effect of Slurry Density on Load Dynamic and Milling Performances in an Iron Ore Ball Mill On line Estimation of In mill Slurry Density April 2012 DOI 10.13140 2.1.4625.8561.
Dec 01, 1989 The effect of slurry density on the dynamics and grinding behavior of a batch ball mill was studied using quartz as a test material. It was found that slurry density determined the distribution of solid charge in the mill, with migration of particles from the tumbling zone to the mill periphery as solid concentration was progressively increased.
Overflow ball mills rotary speed influences the motion state of steel balls. Under the low speed circumstance, steel balls drop after rising to a certain level, with grinding as main acting force supplemented by the impact. If increasing the speed, steel balls are thrown and fallen, with impact as main acting force supplemented by grinding.
