Heat Balance Grinding In Ball Mill. The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals.

hammers are also common in hammer mill designs. Hammer mills are recognized as technology capable of finely grinding the greatest variety of materials [3,13] and are noted for achieving high size-reduction ratios and yielding cubic-shaped particles [14,15]. Hammer mills have a wide application in biomass size reduction

Therefore, grinding is generally analysed using the energy-size relationship models such as the Bond, the Kick, etc. However, problems arise in the scale-up procedure due to the lack of information about grinding kinetics and mass transport in these models. Therefore, grinding can also be analysed using the kinetic (population-balance) models.
