A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size.

drive supplier (Siemens or ABB) before the mill vendor can start the FEA & basic design work which takes a further 6/8 weeks. This is not the case for mills with geared drive as engineering can commence immediately by the mill vendor. Gearless drive rotating elements are heavier in construction than an equivalent gear drive grinding mill.

Pre-assembled range of ball mills for smaller capacities with the following features and benefits: Bolt-on trunnion and drive shaft with integrated discharge ports; Single-piece fabricated mill shell with integral heads; Drive shaft arrangement. Drives mill centrally at discharge end – no girth gear/pinion required

Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼" to 1.5". The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.

All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific ...

With more than 100 years of experience in ball mill technology, 's ball mills are designed for long life and minimum maintenance. They grind ores and other materials typically to 35 mesh or finer in a variety of applications, both in open or closed circuits.

drive and design optimization towards specific customer requirements. Overview of a GMD System A GMD with a high power of up to 20 MW and more, as a result of today's requirements for ball and SAG mills for the minerals industry, has of course a certain complexity. It should not anymore be regarded as a simple single drive.

The time has come to re-think our approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services. This paper looks at the serviceability and economics of five different mill motor

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
