Energy consumption and output. Cement mills are normally driven by electric motors. Modern installations draw power of 2-10 MW. The power (in kW) required to turn a ball mill is approximated by: P = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in …

Ball mills are most commonly used in cement factories to grind the raw material and finely grind the cement. The use of ball mills in cement grinding is due to several factors, among which are relatively simple design and high processing rate. However, these machines have certain limitations as well. It is known that only 2 to 20% of the energy ...

Type of feedstock, moisture content, and starting milling size also influence the energy demand. Knife and hammer mills are more economical with energy consumption between 1 and 130 kWh t − 1 in comparison to disc and ball mills (52). Extensive milling of lignocellulose also alters its physical structure and enhances its reactivity (53,54).

Due to the low mill capacity (kg/h) and high energy consumption, production of particles in ultrafine size range is an extremely difficult and expensive procedure. According to these facts, the optimal ratio (ratio of the gyration diameter to the mill tube diameter) of planetary ball mill for ultrafine grinding was intensively studied [ 7 ].
