1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.

Since the 1970s, the semi-automatic grinding process has been diversified, from the initial single-stage semi-automatic grinding process to the semi-automatic grinding + ball milling (SAB) process and then to the semi-automatic grinding + ball milling + stone crushing (SABC) process. Compared with the traditional crushing and grinding process, the semi …

During front end engineering, these results were used to size the grinding mills ired to treatrequ 3000 t/d in 3 grinding mill configurations: namely SAB, SABC and Rod Ball. At the same time it was agreed by Fortune that more data should be gathered to ensure that the mill design conclusions were correct.

Mill (grinding) Wikipedia. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. get price

The circuits developed are: a crushing and ball mill circuit (CB), a SAG mill and ball mill circuit (SAB) and a single stage SAG mill circuit (SSSAG). For the SAB circuit, the use of pebble crushing is analyzed (SABC). An industrial circuit for 25 million tons of run of mine was developed for each route from tests on a pilot scale (grinding ...

SABC Grinding Circuit Operation & Optimization. When operating a grinding circuit (at Granny Smith ) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations.

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.

The main objective of this research was to advance the understanding of the potential benefits of the proposed HPGR stirred mill-based comminution circuits for low-grade, high -tonnage base metal operation. Samples and operating data were collected directly from the existing SAB/AGBC/SABC circuits to establish a base case for comparison.
