The working principle of ball mill
Therefore, in the rolling ball mill, the grinding efficiency is increased as the ball diameter decreases. It has been proven that the highest grinding efficiency can be obtained with a small ball of .mm diameter. However, the ball diameter is too small to wear too fast, and it is also difficult to discharge due to the small gap of the ball. Therefore, the ball used in wet-grinding the mixture

Ball mill
• Weight of the balls: With a heavy discharge of balls,we get a fine product.We can increase the weight of the charge by increasing the number of balls or by using a ball material of high density • Speed & rotation of Ball mill: low speeds,the balls simply roll over one another and little grinding is obtained while at very high speeds the balls are carried along the walls of the shell and

Ball milling pretreatment of corn stover for enhancing the efficiency
The optimum parameters for the milling process were ball speed of 350 r/min, solid/liquid ratio of 1:10, raw material particle size with 0.5 mm, and number of balls of 20 (steel ball, Φ = 10 mm), grinding for 30 min. In comparison with water milling process, alkaline milling treatment could increase the enzymatic hydrolysis efficiency of corn stover by 110%; and through the digestion process

Impact of ball filling rate and stirrer tip speed on milling iron ore
In addition, operational parameters such as ball filling rates, stirrer tip speeds and grinding time have been investigated in terms of the width of PSD and specific energy input. The results indicated that slight differences in the width of PSD could be observed at different ball filling rates and stirrer tip speeds. It was also found that increasing the ball filling rate and stirrer tip

Thus, an increase of σ r (t mill ≤ 2 h) and (BH) max (t mill ≤ 4 h) is observed at the initial stage of the milling process. Like an increase in the ratio m, a subsequent increase of t mill leads to a rapid decrease of the σ m, σ r, and (BH) max of powders milled with added surfactant due to a deterioration of the powder alignment.

Ball Mill
The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.
