However, grinding balls are perfectly suited to the attrition of materials and powders. This is called a ball mill or grinding machine: the balls and the product to be ground are placed in a container, which is set in motion, in rotation. The attrition is then achieved by a mechanical grinding mechanism due to the friction of the balls on the ...
Jan 1, 2022 · 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 ...
