Apr 01, 2013· 1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).

Ball Mill Design Parameters. Size rated as diameter x length. Feed System. One hopper feed; Diameter 40 – 100 cm at 30 ° to 60 ° Top of feed hopper at least 1.5 meter above the center line of the mill. Feeder. Single or double helical scoop feeder or a spout feeder; Double helical feeders used in closed-circuit with classifiers

Youga Gold Mine utilizes Open Pit Mining Method followed by conventional Gravity-CIL circuit. Processing Plant consists of three-stage crushing, single-stage Closed Circuit Ball Mill with Hydrocyclone Batteries, where one-third of the underflow reports to Knelson Gravity Concentrator, and Cyclone Overflow reports to Carbon-in-Leach Circuit for cyanidation.

Air-Swept Ball Mill Used in dry closed-circuit grinding, air-swept ball mills allow fines to be extracted from the mill as soon as they are produced. The airflow temperature can be varied and limited drying can be achieved. Tube Mill A parallel mill of large length to diameter ratio, a tube mill is used for wet or dry grinding in open circuit.

PATTERSON Continuous Ball, Tube and Rod Mills are designed for open or closed circuit grinding under the most severe and exacting applications.
