Ball mills are fine grinders, have horizontal ball mill and vertical ball mill, their cylinders are partially filled with steel balls, manganese balls, or ceramic balls. The material is ground to the required fineness by rotating the cylinder causing friction and impact. The internal machinery of the ball mill grinds the material into powder and continues to rotate if extremely high precision

Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.

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. 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

The Best Ball Mill Maintenance Pdf In Chile. the-best-ball-mill-maintenance-pdf-in-chile As one of the worlds biggest copper ore operations the Chilean mining company Compa241237a Minera Do241a In233s de Collahuasi based in Las CondesChile commissioned Siemens to modernize the drive system of four of its ore mills The mine is located in the North of Chile around 180 kilometers

As well as ever larger SAG mills, ball mills are also expanding in size. In the late 1990s the trend moved towards using GMDs to power these larger ball mills, as well as using the drive to vary the speed. GMDs quickly moved from 20’ ball mills, expanding to 24, 25 and then 26’ mills. In early 2010 ABB commissioned the first GMDs for two 27’ ball mills in Chile with a rated power of 18.6

AG 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 done by a ball mill. AG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Lower lifetime cost

ball mills. These characteristics make SAG mills an excellent example of critical equipments whose continuous and stable operation is essential to guarantee mineral processing plant profitability [1]. To achieve improvements in the production capacity and energy efficiency of an industrial tubular ball mill, some researches were done such as monitoring level of coal powder filling in an

Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral

Difference Between Sag Mill vs Ball Mill mech4study. Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a S mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating

SAG mills mimic the same shortcoming. It follows that in order to obtain the speciﬁ c energy (SE) to achieve a certain transfer size, based on the 80 per cent passing value, an inefﬁ ciency factor must be applied to the SE of single stage ball mills, rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method. Rod mill and AG/SAG mill products are similar and

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 to optimize mill performances. Since comminution is concerned with liberating valuable minerals for recovery in the separation process, it is crucial to run the mills at the
