Here we will give you a complete guide on what is a ball mill vs SAG mill, how they are different, and how they are used. Let's get started! Operating Principle. The operating principle difference between a ball mill and a SAG mill is their specific energy consumption. Ball mills use an induced storage mechanism to grind materials.

If the SAG mill is not intended to be the rate-limiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere. Underground mines are an example: the hoisting capacity of the mine shaft is the rate-limiting step in the process, and the SAG mill must adapt to ...

cement industry. The GMD is also known as "wrap-around motor" or "ringmotor". Almost 25 years later, the first GMD with 12.0 MW power and 13.0 rpm was installed in the minerals industry. Since then, numerous GMDs for ball mills and SAG mills have been installed in the minerals industry. The main advantages are that the GMD is

Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These

With our SAG mill running at 65.4% critical speed (mill @ 8.7 RPM), the SER motor speed reference is 850 RPM or 85% of 1000 RPM. We are recovering approximately 1.2 MW of slip energy; the power ...

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.

High cost-effectiveness CITIC HIC grinding mills are recognized as China's Manufacturing Industry Single Champion Product. CITIC HIC is responsible for setting the national standards of semi-autogenous mills (SAG mills) and ball mils, supported by powerful database, optimized process technology, cutting-edge design concept, and 60 years of …

This makes the mill essentially a part of a synchronous .motor rotor with the stator in its usual position around the rotor. Inherent in this type of drive is limited speed variation. This has many interesting implications with regard to mill automation where ores are variable.

"wrap-around motor" or "ringmotor". The motor rotor is composed of individual poles mounted on the mill flange. The number of poles is based on the required speed of the mill. Thus, the SAG mill motor has 72 poles and the ball mill motors have 56 poles. • Excitation transformer and excitation converter with full wave control.

The SAG mill was sized with 746 kW to give a 25% contingency for power swings on the calculated power. The ball mill was sized at 1120 kW. Total installed power for comminution exceeded that required for conventional grinding by a …

(also called wrap-around motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive. The fuseless
