A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher.

The rod mill media and ceramic ball mill media appearance ratio rod mill whose appearance is the same as that of the industrial ball mill the difference is that the ratios of cylinder shape are different for example the length ratio of the rod mill to the diameter is generally 15 20 and the inside lining plate on the end cap is the.
The mill was expected to produce a product of 80 passing 150 m.The feed rate to the mill was 300 th.The ball mill grindability test at 65 mesh showed 12 kwht.The internal diameter of the ball mill was 5.03 m and the length-to-diameter ratio was 0.77.The steel balls occupied 18 of the mill.The total load occupied 45 of the mill volume.
Design limitations on mill diameter have been exceeded. For example, the DL ratio for 32 ft dia. mills decreased from 3.001 to 2.171 over 35 years until the advent of 36 ft dia. mills in 1973. The DL ratio for 36 ft dia. mills decreased from 2.531 to 2.061 over 23 years until the first 38 ft dia. mill was purchased in 1996. The 38 ft dia.
The ratio of machine length to the cylinder diameter of cylindrical type ball mills range from one to three through three to one. When the length to diameter ratio is two to one or even bigger, we should better choose the mill of a Tube Mill. Grinding circuit design

As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used. The size of the step-over distance and the tool diameter will determine the scallop height between each step.

The ratio of cylinder length to diameter of rod mill is generally 1.5-2.0, and the inner surface of liner plate on end cover is vertical plane. In most cases, the ratio of the length to the diameter of the ball mill is only slightly greater than 1. In addition, with same specificationthe, the cylinder rotating speed of the rod mill is lower ...
Acid hydrolysis was then performed using sulphuric acid 47 wt for 90 minutes at 45 176C. The ball mill worked by cracking the cellulose microfibrils along their longitudinal axis leading to nanofibers with a shorter diameter and length when longer milling times were applied.
