Ball Mill Alignment


Ball mills are rotary equipment with relatively high speed of operation commonly used at industry. In fact, due to this higher speed of rotation all the components: pinions, gears, main and auxiliary drives has to be set in a very precise way. Mutual, correct positioning of such elements guarantees their durable and long-term operation.

Even the equipment, which cause no problem with the operation, over time will show some higher or lower deviations in components position. Mainly due to: wear, vibration, support displacement etc. Frequent monitoring allow to detect even smallest misalignment at a very early stage. This preventive proceedings will reduce damages to the minimum.


Determining dynamic run-out at a gear station (axial and radial).

Specification of level of consumption of overlapping elements.

Specification of non-alignment deviations in a vertical and horizontal plane in relation to a specific reference line.

Proper placing of pinion(s) axis relative to the girth gear (drive wheel) - value of clearances between working teeth.

Alignment of clutch system, gears, gear boxes and drive motors regarding pinion's and mill axes.

Determining the level of displacement of supports over time.


Higher durability of machinery operation

Cost-efficiency - cost of components exchanged

Lower number of unplanned standstills

Stopping the process of damages progression - non-aligned components have a negative impact on devices located in direct neighbourhood.

Decreasing vibrations - longer longevity of individual elements of machinery and devices.

Hot kiln alignment - the main area of our actions shall be to conduct mechanical inspection and to specify activities (measurements, exchanges, repairs, modifications, etc.) which should be performed to attain and maintain high effectiveness of the rotary kiln's operation.


We hold a specialist hardware and software used for professional measurements. Application of relevant tools allows for effective diagnosis and monitoring of machinery and equipment operation.


We developed high precision measurement systems to allow to monitor current status of equipment and to plan maintenance activities. Hence, malfunctions and breakdowns can be reduced both in respect of their intensity and frequency.


We provide a wide scope of measurement services addressed to many industry branches. Highly precise measurements are the starting point for analyses and regulations supporting the work of machinery and equipment.
