In Figure 7.35 shows the SAG mill closed with a crusher (recycle or pebble crusher). In SAG mill operation, the grinding rate passes through a minimum at a “critical size” (Chapter 5), which represents material too large to be broken by the steel grinding media, but has a low self-breakage rate. If the critical size material, typically 25–50 mm, is accumulated the mill energy efficiency

Semi Autogenous Design FactorsSag Mill Operation ExampleProcess Plant DescriptionSag Mill Design and SpecificationOperating Problems Since CommissioningDesign Changes and Future Operating StrategiesThe design of large mills has become increasingly more complicated as the size has increased and there is little doubt that without sophisticated design procedures such as the use of the Finite Element method the required factors of safety would make large mills prohibitively expensive. In the past the design of small mills, up to +/- 2,5 metres diameter, was carried out using empirical formulae with relatively large factors of safety. As the diameter and length of mills increased several critical problem areas were ident

The pebble crusher refers to the type of crusher used in the aggregate production line, such as jaw crushers, impact crushers, cone crushers, VSI crushers. Due to its hardness, the pebble crushing consists of two or three steps, usually the coarse crushing, secondary crushing, and fine crushing. However, different sizes of pebble have varied applications, if aggregate producers have particular

23/10/2019· Robustness of the crusher: Pebble crushing is the toughest of crushing applications, so a crusher needs to be robust. Our Trio® TC series cone crusher is typically 40-50% heavier than similarly sized machines in the market and provides a superior level of protection against fatigue. When pebble crushing, weight really does matter. Ability to handle variable feed: When a crusher has the

Oversize pebbles from the trommel are conveyed to a surge bin of 735 t capacity, adjacent to the pebble crushers. Two cone crushers with a closed side set of 12–16 mm are used to crush the pebbles with a designed product P 80 of 12 mm and an expected total recycle pebble rate of 725 t h −1. The crushed pebbles fall directly onto the SAG mill feed belt and return to the SAG mill.

SAG Mill Grinding Circuit Design

Adding pebble crushing as a unit operation is the most common variant to closed-circuit AG/SAG milling (instead of direct recycle of oversize material ). The efficiency benefits (both in terms of grinding efficiency and in capital efficiency through incremental throughput) are well recognized. Pebble crushers are effective at reducing the buildup of critical-sized material in the mill load. Critical-sized particles are

It is possible, however, for either SAG mill to be fed from either crusher, and for the circuit to operate with one SAG mill and one or both ball mills offline, depending on operating and maintenance requirements. The SAG mills are closed circuited with a pebble recycle circuit, and a pebble crusher was installed on this recycle line in the third quarter of 2018. The ball mills are close circuited with hydrocyclones, with

23/12/2017· calculations define the efficiency of a fine stage-crush ball mill circuit as 1.0 to 1.2 depending on ball mill feed size, and some SABC (SAG/ball mill/pebble crusher) circuits operating with an efficiency of 1.3-1.4 or higher on coarse feed. If the coarse feed size is reduced, the circuit efficiency will approach that of the stage-crush and ball mill circuit.
