Their construction allows for increased electrical efficiency when a low speed is required (as in ball mills and similar apparatus). 1.1.1 Basic construction and operating principle Three phase AC synchronous motor are commonly used in industrial applications. This type of motor has three main parts, rotor, stator, and enclosure.

Schematic drawing of an attrition ball mill. The attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media, usually 12 mm or larger, and run at low rotational speeds of 10–50 rpm.

In case of continuously operated ball mill, the material to be ground is fed from the left through a 60° cone and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to the feed), from near the top of the shell.

A Van de Graaff generator can produce extremely high potential differences (voltages). A small school version can pump a huge charge onto the top dome so that the potential difference between the dome and the earth can be 200 000 volts yet the total charge is so tiny that you only receive a small shock when you touch it. This makes possible dramatic demonstration …
