Are you using ball mill to homogeneously mix two typs of particles or you would like to refine the particles or you expect to have a chemical reaction inside the jars.
Feb 12, 2013· Ball mil design calculation?? – Yahoo! Answers. Apr 01, 2008 · Best Answer: A ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a . »More detailed
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 μm. If the rod mill fi nes are taken into account the rod mill product can be theoretically corrected to show a P80 of 1700 μm, .
Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.
Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.
involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from to
The second approach to ball diameter calibration is the socalled absolute method. In absolute measurement, temperature is a first order error, that must be held at 68 °F (20 °C) exactly, or any variations must be compensated for. A micrometer or threaddriven measuring machine is an example of the absolute concept.

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

Through the analysis of the interaction form between steel balls and the material in Microlevel, the primary form in different areas confirmed and the requirement of ball grading presented. The different methods of ball grading and the different influence on the interaction between steel balls and the material clarified. At last, a clear description of the calculation method of the ball ...
In tnis series tne original coarseness of the mill's feeding (d) and the sizes of the balls (D) were changed. The end fineness of of the material remained constant in all cases: d = 74 microns, that is, the pulverization was reduced as far as a 10 residue on a 200 mesh screen.
