It is commonly referred to as a SABC circuit, for Semi-Autogenous Ball mill Crusher (SABC). This circuit shows a semi-autogenous grinding (SAG)/ball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of ‘critical size’ material in the circuit.
A series of comminution tests was carried out to evaluate three multi-pass HPGR circuits and a jaw crusher- ball mill circuit. Combinations of HPGR units (1.0 m and 0.25 m diameter), jaw crushers and Bond ball mills were used to grind a 32 mm top size porphyry copper feed (BBWI = 12.1) to a product P80 size of about 150 m.
2009 and treats a sulphide copper-gold ore to produce gold in form of dor bars and a concentrate containing gold, copper and silver. The BGM comminution circuit includes a primary crushing stage with a gyratory crusher and a two grinding circuits using a Semi-Autogenous Grinding (SAG) mill and a ball mill. The SAG mill circuit also includes
26 ABB review 314 An example of an industry-standard comminution circuit providing high throughputs can be seen in 3. This cir-cuit, however, has a high specific energy consumption per ton of ore processed, driven primarily by the low efficiency of the ball mills and the need to use steel media for grinding. Ring-geared mill drive
The most energy efficient of the circuits tested was a three-pass HPGR circuit with a 1.0 m diameter roll on the first pass in closed circuit with an 8 mm screen followed by a second and third ...
7.5.2 Circuit Operation. Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12). Parallel ...
Apr 24, 2014 Metso PTI and Antamina staff also analyzed historical data, reviewed the current operating practices of the primary crusher, the SAG and ball mill grinding circuits, and conducted a number of audits and surveys. These data were used to develop mathematical models of the drill and blasting, crushing and milling operations.
(a semi-autogenous grinding mill, ball mill, and tower mill) in the processing plant that would progressively reduce the size of the rock. The finely crushed copper-enriched rock would then enter a flotation circuit where copper would be separated from non-copper bearing rock through chemical and physical processes.
copper-enriched rock mined would be hauled by articulated underground haul trucks either to the surface crusher or to the ore stockpile. Crushed copper-enriched rock would travel to a surge bin through a series of three grinding mills (a semi-autogenous grinding mill, ball mill, and tower mill) in the processing plant that would
