THE OPTIMAL BALL DIAMETER IN A MILL

2012-5-15  The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

Optimum choice of the make-up ball sizes for

2013-9-1  gives the optimum composition of 40% 50.8 mm ball and 60% 25.4 mm balls for a 1 m diameter mill, and 27% 50.8 mm and 73% 25.4 mm for a 2 m diameter mill when grinding from a 90% passing 9.5 mm feed to an 80% passing 150 μm product. The portion of 50.8 mm balls decreases as the feed size or the product size decreases. However, this can be a good starting point for determining the optimum composition of the make-up balls

Ball Mill - an overview ScienceDirect Topics

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. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Why use Different Size Balls in a Mill

2017-7-3  Finally, a cylindrical mill with a grid was used. The grid was 1 foot from the feed end of a 2- by 3-foot cylindrical mill. Balls of 2.5 inches to 1 inch were placed in the feed-end sections and 0.75-inch balls in the discharge end. The grinding was moderately better than without the grid.

Ball Mill Loading - Dry Milling - Paul O. Abbe

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball

British Cannonball Sizes

2021-7-16  The difference in diameter is termed "windage". The final bore diameter and hence the windage of earlier 16th and 17th century guns was a matter for the skill of the gunfounder. A value of 0.2 to 0.25 inches was typical. Albert Borgard specified that along with the weight of cannonballs the windage of the guns should be standardised.
