With than 100 years of experience in ball mill technology, Metso 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.The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed.
The process plant long lead items have started to arrive on site, with the ball mills scheduled to arrive in mid 2020. The initial shipment for the first line includes a 7,800 kW primary ball mill 21 ft by 31.5 ft and a secondary ball mills of the same power rating and size.The present mill inlet chute can be used for the two compartment ball mills only in which primary and finish grinding both are takes place. It may be a closed or open circuit grinding systems. In recent days, the Ball mill grinding systems are used with the Roller press and it is developing very fastly.
In a SAG and Ball mill circuit where there is no scope for storage capacity between milling stages and throughput is normally limited by a bottleneck at one stage or the other. In this case any ore with a high BWi value will have reduced . throughput due to the ball mill despite the capability of the SAG mill.We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.

Keywords Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.Conical Ball Mills Used wet or dry, closed or open circuit, conical ball mills provide a classifying action within the body of the mill due to particles of greater size tending to reside at a point of greater diameter. This characteristic delivers increased efficiency and lower power consumption. Conical mills may also be air swept when run dry.
Aug 29, 2018 Karara Mine has decided to shift the comminution workload from the primary ball mill to the TowerMill circuit by bypassing the 100 m fine screen in between the ball mill and TowerMill circuits. This action has increased the circuit feed particle size distribution with a top size close to 1 mm.Mathematical modelIn a series of open circuit tests reported by Dorr and Anable (1934) limestone was ground at various feed rates in a 3 ft ball mill. The production of fine material (final product) increased with increased feed rate, and the relationship is a straight line in log log space.
