- length diameter ratio in ball mill

The cylinder length-diameter ratio of rod mill is generally 1.5-2.0, while the cylinder length-diameter ratio of ball mill is smaller, only slightly greater than 1. In addition, the cylinder speed of the rod mill is lower than that of the ball mill, so the grinding medium works in the cascading state. 2.

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

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.

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.

Jan 07, 2015· The difference between ball mill and tube mill is the ratio of the tube length to the tube diameter. Tube mills have a ratio of length to diameter of [3-6 : 1], for ball mill this relation is[<2 : 1]. Two different processes occur inside the mill: 1- Crushing: Breaking up of the incoming particles from a size of about 30 mm to a size of minus 2 ...

The hulls were crushed with the use of a Legend rod mill rotated by a US Stoneware roller. 24–26 A total of twenty-three rods were contained in the mill; nine of them had a diameter of 1.9 cm, eight had a diameter of 1.6 cm, and six had a 1.3 cm diameter.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
