About This Product
A ball mill is a standard size-reduction machine in engineering laboratories. Material and steel balls are loaded into a horizontal drum. As the drum turns, baffles lift the balls and they fall back, breaking the material by impact. Students vary the drum speed and note the power drawn on the energy meter, then sieve the product to judge grinding efficiency. The revolution counter records the turns of the drum.
Frequently Asked Questions
Q1. How does the Ball Mill reduce particle size?
Baffles in the rotating chamber lift the steel balls, and size reduction happens by the impact of the balls as they fall back.
Q2. Which experiments can be done on it?
The effect of rpm on the power consumption of the mill and the grinding efficiency for a material. A set of sieves with a sieve shaker is needed for analysis.
Q3. What are the feed and product sizes?
The feed size is about 6 mm and the product size is about 200 mesh.
