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. The final stages of comminution are generally performed in ball ...
