Technical Evaluation and Practical Experience of High-Power Grinding Mill Drives in Mining Applications José R. Rodríguez, Senior Member, IEEE, Jorge Pontt, Senior Member, IEEE, Patricio Newman, Rodrigo Musalem, Hernán Miranda, Luis Moran, Fellow, IEEE, and Gerardo Alzamora Abstract—Grinding mill drives play an important role in the mining industry.
Where power exceeds this, drives become so large and motors become special, resulting in an uneconomical application. Generally the driven mill sheave is of split hub construction to facilitate field assembly. V-belt drives allow use of higher speed motors, generally low in initial cost. Motor speeds should be between 580 and 1160 rpm.
drive of a grinding mill is the crucial piece of equipment in the concentrator – and why it is subject to very high demands. High availability and reliability through-out the entire lifecycle are a must, while ... fies the requirements of all grinding motors. The revers-
Mill drives in the cement industry cover a wide range of mechanical drive and motor applications. This paper includes an overview of the various mill drive options with an emphasis on single motor drives. A more detailed review of the most recent drive development, the compact drive, is featured.
Grinding mill drives play an important role in the mining industry. Almost 60% of the electrical energy consumed by modern concentrator plants goes to grinding mill drives.

Ring-geared mill drive For mills with standard diameters or requiring less than 20 MW (approx.) of power, ring-geared mill drives (RMDs) offer the best solution. Three of the most common drive types for RMDs are low speed motors without a gearbox, high speed motors with a reduction gearbox, and variable speed drives (VSDs). No gearbox: The low speed motor is connected directly to the pinion. The rated speed …

• Gearbox. Because these drives are so heavy, their supports sometimes settle, causing substantial misalignment of the housing bores. Alignment is best evaluated by performing a detailed analysis. • Lubrication. Usually, all gear drives (and supporting bearings) in a …
Achieving motor system optimization requires careful consideration of the overall motor system and selection of the right equipment, including eficient motors and, where appropriate, drives. To ensure that motor-driven systems continue to perform optimally over time, it is critical to develop and maintain a motor management plan.
The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is …
For this purpose, Siemens supplied the gearless drives for a 36-foot SAG (Semi Autogenous Grinding) mill with a rated power of 15 megawatts and a 26-feet ball mill with 15.5 megawatts of rated power. The order was worth around 16 million euros
Our portfolio includes a wide range of low voltage drives, medium voltage drives, DC drives, scalable PLCs, motors, mechanical power transmission, and a selection of HMIs. From crushers to fans, from separators to kilns.
The specialized motors with synchronous technology have been designed to address industrial applications that demand a very application and industry specific design. Examples include high-speed compressor drives for compressors with up to 100 MW and higher, gearless ring drives for ore mills, gearless drives for excavators and POD drives for ships.
Typical mounting conditions for these reducers are.500 KNm Mill torque. the further development of the roller grinding mill and the industrial introduction of high pressure comminution have achieved energy savings in the grinding process of between 30 and 50%.
This paper presents a technical evaluation and practical experience of two different technologies used in high-power grinding mill drives. The analysis is focused on the static power converter and associated control scheme required to drive the motor.
For vertical mills, in the most confined spaces the highest power ratings are required as well as maximum availability, the gear unit being the central element. It has to transmit the power, reduce the motor speed to the required mill speed, and support the grinding table.
Modular high voltage synchronous motors, with power ratings extending up to 100 MW (or higher on request) and with speed ratings up to 7000 rpm, specifically designed for compressor applications with very high power and speed ratings.
A wide selection of lids and containers allows for adaptation of the mill to individual application requirements. The GRINDOMIX GM 200 meets and exceeds all special laboratory and analytical requirements and is a professional device superior to any commercial household mixer.
