3. The ball mill is very noisy machine, particularly if the casing is of metal, but much less so if rubber is used. 4. Relatively long time of operation. Critical speed of ball mill: The faster the mills are rotated the further the balls are carried up inside the mill and the greater the power consumption and capacity of the mill.

A fluid energy mill is also known as a pulverizer, micronized, or jet mill. It is used for fine grinding and close particle size control. The reduction of the particles takes place by the attrition and impact mechanism by the air or inert gas introduced through the nozzles present in the chamber. This mill is mainly used to grind heatsensitive ...

During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.

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 have been designed in standard sizes of the final products between mm and mm in diameter. Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls.
