MVR vertical mill with conventional drive: economical solution for small to medium output rates

For the preparation of cement raw material, cement, and granulated blast-furnace slag with small to medium output rates, the MVR mill with conventional drive is the right choice. This mill type is by the way the core piece of our modular ready2grind system. High plant availability and optimized maintenance concepts are the features that make sure the mill meets the ever rising requirements of the industry. In combination with the conventional drive, the MVR mill ensures small to medium output rates, reliably and on the long term.

ADVANTAGES OF THE MVR MILL WITH CONVENTIONAL DRIVE

Grinding roller system with active redundancy

Up to six grinding rollers may be swung out separately, using only one hydraulic unit for maintenance and operation. This system is actively redundant meaning that operation continues while two or several opposite grinding rollers are taken out of the system.

Optimum utilization of process heat

The thermal energy of process gases can be used on MVR mills.

Homogeneous compaction of the material to be ground

Thanks to the geometry of the grinding rollers in combination with their specific suspension, there is always a parallel grinding gap, ensuring a homogeneous compaction of the material to be ground. Moreover, due to the symmetric shape of the grinding roller tires, these can be turned when worn.

Highest availability

Thanks to low specific wear rates, high-quality wear materials and sophisticated service concepts, maintenance times of the MVR mill are reduced to minimum which is additionally supported by the active redundancy of the grinding rollers.

Low capital expenditure

MVR mills need only few peripheral machinery, no or little walled-in space, their operation is dust-free and they have a low noise level.

Favorable control behavior

High drying capacity, short dwell time of the material to be ground, and remote control of grinding pressure and classifier rotor speed ensure a fully automatic operation of the MVR mill even with varying raw material characteristics.

Low electric energy consumption

The grinding principle and the high efficiency classifier ensure the reduction of electric energy consumption by up to 40% as compared with conventional ball mills.

Increase of output rates by installing a MultiDrive®

The Pfeiffer MVR mill may also be equipped with the patented MultiDrive®.
