At low speeds, the balls roll over each other, and attrition (rub bing action) will be the predominant mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Construction of ball mill. The construction of a ball mill is shown in Figure 1. A ball mill consists of a hollow cylinder, which is ...
I guess I have been duped, but I bought a solid iron ball that the seller said is a 12 pound cannon ball. When I got home, I found that it weighs 16.4 pounds, and has a diameter of 4.8 inches. I can see a faint mold seam, and it has some moderate pitting. I bought this item for my grandson to...
Abstract: To solve the problem of mill current fluctuations caused by sudden input changes in the cement combined grinding system, this paper built a mathematical model of the ball mill load and designed a sliding mode control for ball mill load based on prescribed performance. The prescribed performance formula is introduced into the ...
