When you add water to the feed of the cyclone, the result is the overflow becomes lighter and the underflow becomes heavier. The heavier UNDERFLOW DENSITY will give the ball mill more work to do. This is reflected in a heavier density being fed back into the hydrocyclone feed pump box. Which again changes the hydrocyclone operation performance.
The ball charge typically occupies around 30%36% of the volume of the mill, depending on the mill motor power and desired energy consumption and production rates.

Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually times the shell diameter (Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...
The volume of pulp in some experiments was increased to mimic pulp filling in an overflow discharge ballmill. All the experiments in this phase were conducted using a silicate ore. The rate of production of material finer than 75 µm, when using a 25/75 mixture, was virtually identical to that of the corresponding ballmilling experiment.

Ball mill balls. Ball mill balls are a type of ball used in ball mills, usually made of highhardness materials such as steel, ceramics, hard alloys, etc. Ball mill steel balls is an important part of the ball mill, its main function is to carry out the grinding operation in the ball mill, and the material is crushed into the required size.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
Abstract. The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions.
The poor performance of the ball mill might have been due to higher circulating load and coarser feed coming from the SAG mill discharge (see Table 5). Hydrocyclones performance based on survey ...
IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of :1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).
04 Raw Mill Building. The raw material is finishground before being fed into the kiln for clinkering. This grinding is done using either ball mills or vertical roller mills (VRM). The raw material is simultaneously dried. Ball mills use impact with attrition principles for grinding the raw material.
Differentiation of KW with respect to V in equation (2) shows that power draw increases with charge level to peak at about Vp = .58. For rod, ball, or pebble mills the peak is usually near Vp = .50, while actual observations as low as V= .42 have bean made in some ball mills (Rowland, 1973). See Figure 2.

A planetary ball mill (Pulverisette 7, Fritsch, IdarOberstein, Germany) was used, in contrast to a vibratory ball mill in Bjorkman's protocol. The extracted sawdust ( or 2 g) was subjected to milling (at various times) at 600 rpm using ZrO 2 bowls and 9 or 17 ZrO 2 balls. Milling was performed at 600 rpm, pausing 10 min after each 30 min ...
