The feed size for a ball mill varies depending on the size of the machine and the material being processed. In general, the feed size for a ball mill is usually less than 20mm or smaller.
Ball mills can be used for dry or wet grinding of various ores and other grindable materials. It has stable operation, reliable operation, large production capacity ... Feed size.: 25 mm. Output: 1-200 T/H. Applicable materials: various ores, gold-silver-copper-iron various metal beneficiation, cement, fertilizers, ...
By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling: while convenient, this has the ...
For each curve any point underneath represents all the possible output mass fractions that can be obtained from milling the two size classes under different conditions of ball match. The graphs show that for a courser feed a three ball mixture (50 + 20 + 10 mm) will provide the much required largest amount of size class of interest.
Ball mills can be equipped with motors ranging from 10 kW to 500 kW or more, depending on the size and desired output of the mill. - Speed: Ball mills are usually operated at speeds between 60% and 70% of the critical speed.
A standard Bond mill (Fig. 1) was designed to perform the work index tests and determine the energy consumption of various s minerals.The mill has a round internal housing at the corners, has no lifters, and is for dry grinding. The inner diameter and the length are 0.305 m, and the ball load is 19.4% of mill volume (equaling a total weight of …
The rod mill was needed to reduce feed size to the ball mill because crushing plant output was normally coarser than 80% passing 10,000 microns. Such feed causes power inefficiency if fed directly to a ball mill. ... As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day. The gain in …

When removing the ball mill liner, the personnel should pay attention to safety, pay attention to the position, and avoid being injured by the ball mill liner. 5. The size of the ball mill is large, and it is necessary to carry out lifting work during the process of replacing the ball mill liner.
Besides particle size reduction, ball mills are also widely used for mixing, blending and dispersing, amorphisation of materials and mechanical alloying [1, 49, 51].
55 known as the distribution function [45, 46]) describes the distribution of fragment sizes obtained after a breakage of particles of size xj.Thus, b1j, b2j, …, bnj are the mass fractions of particles in size classes 1, 2, …, n after a breakage of particles in size class j. The mechanism of breakage is illustrated in [23] by a diagram shown in Fig. 3.
