Aug 25, 2014· Also the ball mill diameters has reached limiting proportions. Hence AG mills came into picture in a large way and were very quickly modified to SAG mills and depending on the hardness of ore the crushing too was included in the circuit, though of course ABC circuits are not that common.
In many grinding plants mills which have metallic or rubber liners suffer from bolt breakage. Our technicians come across broken mill bolts at many sites around the world, to the operators of the mills it is an almost normal occurrence, but if you have breaking bolts there is an underlying problem which needs to be fixed.

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 …
and ball mills, have almost become obsolete in the move to higher milling rates required to process lower metal grades. Grinding circuits with fully autogenous (AG) or semi-autogenous (SAG) mills, often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades.
Difference Between Rod Mill And Ball Mill Difference Between Sag Mill vs Ball Mill mech4study Today we will learn about difference between sag mill vs ball mill A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding crushing or cutting.
A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills.

ρ b = ball density (t/m 3) 9.4. AG/SAG Mill Power. In designing crushing–grinding flow sheets, correct estimations of mill power draw are important as it serves as one of the deciding factors for selecting an option between AG/SAG mills. In most cases, the circuit with the least or optimal power consumption is the preferred choice.
Sag is an acronym for semiautogenous 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 128m in dia,Difference between sag mill and ball mill.
Sag Mill Balls. Difference between sag mill and ball mill solution for ill grinding wikipedia, the free encyclopedia sag mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill sag mill is generally used as a primary or first stage sag millhat online.
The crushed pebbles fall directly onto the SAG mill feed belt and return to the SAG mill. SAG mill product feeds two parallel ball mills of 6.6 m×11.1 m (internal diameter×length), each with a 9.7 MW twin pinion drive. The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

The apparent difference between ball mill and AG/SAG mill efficiency is an artefact of Bond's implicit assumption that the particle size distributions can be defined by one point, the 80% passing size. In fact, Bond noted that this convenient assumption was valid only in cases where the cumulative particle size distributions were roughly parallel
