Ball Mill. The ball mill's basic concept dates back to prehistoric times when it was used to grind flint for pottery. A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell.
The working of a ball mill can be understood as follows: A powder mix is positioned in ball mill and is subjected to high energy collision by the balls (Figure 1). The ball milling process can be summed up as: a. It consists of stainless steel chamber and several small iron, silicon carbide, hardened steel, or
In the pharmaceutical industry, sometimes the cylinder is lined with rubber or porcelain. Figure 1: Ball Mill. The cylinder contains balls that occupy 30 to 50 % of the mill volume. The weight of the balls is kept constant. The ball size depends on the size of the feed and the diameter of the mill Balls are made of steel, iron, or stoneware.
Ball mills use a feed of about 15 mm (½ in.) or finer and product size is very fine with no actual grind limit indicated. Examples include use in mineral dressing processes, paints, pyrotechnics ...

When Kincaid lignite was pulverized utilizing inthemill drying at product moisture content in the range of 11 to 12 percent, the comparison factor was for pulverization in the ball mill and in the hammermill. Power requirements at these conditions were kwhr/ton in the ball mill and about 17 kwhr/ton in the hammermill.
A tumbling mill is a collective name for the generally known ball mills, rod mills, tube mills, pebble mills and autogeneous mills. For all these kinds of mills the mechanics can be dealt with together, there being no substantial difference in the grinding process. There are two kinds of grinding body movements: either they describe an ...
Conical Mill Grinding Tests. In the laboratory work described in the following pages, a 4 ½ft. Hardinge mill with three removable cylindrical sections, 16 in. each in length, was used. Fig. 1 shows the mill with three cylindrical rings in place. This combination allows a mill 4 ½ ft. by 0 in., 4 ½ ft. by 16 in., 4 ½ ft. by 32 in., or 4 ½ ...
The speed of mills depends upon their diameter; a ballmill of 3 feet revolves 35 times a minute, and one of 5 or 6 feet, 29 or 27 times. Tubemills run at a revolution or two faster (see Fig. 117). Some ores require much finer grinding than others to liberate the minerals, and this increases the milling cost. Ball Mill Product Classifying
Dry gringing Hardinge mill Several factors influence the efficiency of ball mill grinding. The pulp density of the feed should be as high as possible, consistent with ease of flow through the mill. It is essential that the balls are coated with a layer of ore; too dilute a pulp increases metaltometal contact, giving increased steel ...
