1. Introduction. Ball mill is one of the most commonly used mills for the crushing and grinding of mineral ore. It is generally used to grind material down to the particle size of 20 to 75 μm and can vary in size from a small batch mill up to a mill with outputs of hundreds of tonnes per hour.
o For ball mills, only 3 – 6% of absorbed energy is utilized in surface production, the heat generated can increase mill temperature to > 120⁰ C & causes excessive gypsum dehydration & media coating if mill ventilation is poor. Types of cement mills. There are basically 4 types of cement mills in use today: Ball Mill (BM)
