A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
Ball mill design is rather simple. This grinding equipment is a drum filled with metal or cast iron balls (grinding media). It is used mostly for production of bulk construction materials, paints, pyrotechnical devices, ceramics and in other industries. The ball mill patent was sealed more than 180 years ago.
3.6.1.1 Ball Milling. A ball mill is a type of grinder used to grind and blend bulk material into QDs /nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.

• A thermistor in the form of bead is smallest in size of diameter 0.015 mm to 1.25 mm. Beads are sealed in the tip of solid glass rods to form problems which are easier to mount than beads. • Glass probes have a diameter of 2.5 mm and length varies from 6 mm to 50 mm. The probes are used for measuring the temperature of liquids. The resistance ranges from 300 Ω to 100 mΩ.
