The optimal retention time depends not only on the feed material and the desired comminution result but also on the ball charge filling ratio and particularly on the L/D ratio. On the basis of the present results and considerations, a specific optimisation of ball mills in semi-finish-grinding plants can be done.
OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. This means that a lower degree of dehydration of the gypsum must be anticipated. This may not be a problem if the gypsum is sufficiently reactive to control the setting reactions, which is normally the case. If in special
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different ...

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
retention time of 10 minutes at a full rated capacity. This means that from the ... Ball mill slakers are an adaptation of ball mills, which originally were designed for wet and dry grinding, to lime slaking. Two types of ball mills are used for slaking, horizontal and vertical. Ball mill
Feb 15, 2019 Diameter and length of the mill, maximum ball size, ball filling ratio, design of the mill liners, and critical speed of the mill are the main factors affecting the grinding forces. Mill retention time is also another parameter that should be taken into consideration.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
oratory mill results to full-scale. 2. Theoretical background Let’s consider a mass of material M in a ball mill that after breakage needs to be divided, by using x i screens, into i + 1 narrow size classes. Normally, for a size class i bounded between two successive screens x i and x i+1 con-taining a mass fraction i(t) at time m t, it is ...
mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of nes present being ﬁ ﬁ ner than 650 μm. These ﬁ nes proceed to the ball mill improving the ball mill efﬁ ciency. Also, the plotted rod mill P80 value, as shown in Figure 1, is 2900 ...
The data shown in column 4 is the recycle rate to the ball mill, vectored down for the provided 16 iterations during a typical retention time T such that the column 4 indication is the ore material recycle rate leaving the spiral classifier and returning to the inlet of the ball mill grinding device.
Grinding Mills: Ball Mill Rod Mill Design Parts. Characteristics of the long mill: Longer retention time per particle and the production of a higher percentage of fines in the micron sizes. This is an important consideration in cement clinker grinding. Capacity per unit of mill weight is greater, with a corresponding reduction in mill cost.
The ball mill is the most common ore grinding technology today, and probably more than 50% of the total world energy consumption for ore grinding is consumed in ball mills.
MATERIAL RETENTION TIME IN A BALL MILL 11.08.2010 The retention time, also called residence time, is the ratio (M/Q) [h]. The flowrate Q could be measured from the production P [tons/h] and the circulating load C and given by Q [tons/h] = C P [tons/h].
