AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG

Mar 10, 2010 Ball mill grinding circuit is essentially a multivariable system with couplings, time delays and strong disturbances.

Apr 08, 2021 In this episode you can find the questions and answers about the grinding circuit. For example why the pulp density is an important parameter for grinding, what the function is of the ball mill and cyclone, why it is important to control the particle size and where in the grinding circuit you need to measure the density.

Grinding Ball Fragments in the milling circuit impact on two critical areas. One is the crushing circuit where companies have observed damage to crushers, unscheduled downtime and loss of production. The other is the grinding circuit where companies have discovered wear to pumps, sumps, piping, hydrocyclones, mill liners as well as inefficient

Advanced process control for grinding circuits White paper 3 Introduction Depending on the ore characteristics and the targeted plant capacity, the design of the grinding circuit may vary significantly. Typically, the circuit consists of several mills (rod, ball, SAG, AG) in series and/or parallel with a number of classifiers and

Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today’s global markets, expanding mining groups are trying

• The ball mill feed is 60 percent plus 106 µm. • The ball mill discharge is 50 percent plus 106 um. • The circuit CSE is (60 percent + 50 percent)/2 = 55 percent. This is the estimated percentage of plus 106 µm solids in the ball mill, and also the percentage of the ball mill

The grinding circuit consists of a conventional SAB circuit with a 7.93m x 3.73 m 3,356 kW SAG mill and a 5.49 m x 8.84 m 4,474 kW ball mill in closed circuit with 6 hydrocyclones (4 operating and 2 on standby). SAG mill throughput typically ranges from 473
