Ball Mills vs Rod Mills - 911 Metallurgist

 — The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%.

 — A cement mill is a fundamental component of the cement manufacturing process, playing a vital role in breaking down and grinding cement clinker into fine powder. This finely ground powder, when mixed with other materials, produces the building material we commonly know as cement. To achieve this crucial transformation, a cement mill …

Neumann Machinery Company (NMC) ball mills have a long and proven history going back to the early 1900's. The first mill designs originated from EIMCO Company originally located in Salt Lake City, Utah.

 — For rod, ball, or pebble mills the peak is usually near Vp = .50, while actual observations as low as V= .42 have bean made in some ball mills (Rowland, 1973). See Figure 2. Power draw is not significantly affected by the presence of the slurry in the mill. While the presence of the slurry will effect the charge density, the charge swelling ...

Media to media contact for rods mills is linear rather than point to point (as with balls) and are much heavier. ... This leads to a narrower size distribution and significantly less slime compared to ball mills. Lower …

The solutions offered by SMS group for wire rod mills are correspondingly versatile. Dimensions from 4.5 to 27 mm diameter in all steel grades can be efficiently produced on such lines. Single- or double-strand high-speed …

In addition, with same specificationthe, the cylinder rotating speed of the rod mill is lower than that of the ball mill. The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
