conventional milling circuit of Palabora Mining Company by B.J. du Plessis* Synopsis Automation of the conventional grinding circuits of Palabora Mining Company (PMC) required that adequate instrumentation and a control system had to be put in place, after which extensive testing had to be done to evaluate different grinding control strategies.
Pebble mills are manufactured for long life and minimum maintenance. They are often utilized for secondary grinding in dry or wet applications. Pebble mills typically reduce ores and other materials to 35 mesh or finer, both in open and closed grinding circuits.
Development of Grinding and Classification Technology It was discovered that closing a grinding circuit with a classification device was beneficial to the comminution process. The first classifiers used in closed grinding circuits were mechanical rake and spiral classifiers and both were used effectively in early grinding circuits.
Apr 15, 2004 The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.
In essence, the circuit will reach an equilibrium product for a given ore type, grinding power and feed rate. The operator or control system can then focus on adjusting the new ore feed rate, mill density etc to achieve the desired grind, therefore always maximising throughput at the target grind for the ore characteristics and available power.
The aspect ratio (mill diameter/mill length) of autogenous and semi autogenous mills varies widely and can be as high as three or as low as 0.5. The literature on the subject of what effect aspect ratio has on grinding mill performance or energy efficiency is almost non-existent. However, at the design stage of many grinding...
secondary grinding circuits and secondary grinding circuit efficiency was improved [10]. Fernandes and Peres used process simulation by computer mathematical modeling, with the objective of implementing an optimized grinding. Classification circuit and the ball mill and hydrocyclones models were after calibrated in [11].
