A. Hardinge mill, the variant of ball mill consist of a hollow cylinder with conical end B. Rods and bars can also be used in place of balls as grinding medium in ball mill C. Ball mill is an open system, hence sterility is a question D. Fibrous materials cannot be milled by ball mill. 10. What particle size can be obtained through ball mill?
The Chilean mill diagram has been superimposed upon that of the ball mill, the excess area of the latter measuring the excess of work done, based upon equal capacity. The great, advantage of the Hardinge ball mill is in its simplicity, reliability, and low operating charges, as Mr. Franke has so clearly shown, and most operators are

A Hardinge mill is a type of ball mill that was around in the days of pan mills. I give you a link to 2 old research papers answering your question in detail when there compare test results of a Hardinge ball mill and a Chilean or pan mill. The ball mill consumes around 30% less power.

Hardinge Mill 59. Hardinge Mill The mill has an advantage over the compound ball mill in that the large balls are raised to the greatest height and therefore are able to exert the maximum force on the feed. As the size of the material is reduced, smaller forces are needed to cause fracture and it is therefore unnecessary to raise the smaller
Harlow Hardinge noticed that rocks of different sizes move at different rates down an inclined surface. This observation led to his development of conical ball mills, wherein the grinding media organized from coarse to fine within the mill, creating grinding efficiencies previously unknown.

In order to get the most economical consumption of power, the ball load in a Hardinge Mill should be kept up to the level of the trunnions. The capacities, power requirements, etc., of the various sizes of Hardinge Ball Mills are given in Table 12. It should be noted that the two figures describing the size of a mill represent the diameter of
Figure 2.27. Cut-away view of the Hardinge conical ball mill showing how energy is proportioned to the work required is about 0.3 kg/Mg of material for dry grinding, and 1-1.5 kg/Mg for wet grinding. The normal charge of balls is about 5 Mg/m3. In small mills where very fine grinding is required, pebbles are often used in place of balls.
In other words, the Hardinge mill gives 76.7 per cent, of its total feed as a product from which the maximum amount of copper can be extracted, while the Chilean mill gives only 36.3 per cent, between the same limits (through 20-mesh and on 200), as is shown in the upper half of diagram.
