Bearings and Bushings Alloys for Mining Equipment

Materion alloy solutions provide greater uptime and wear resistance for use in bushings, bearings, wear plates and other sliding bearing applications. Our alloys are proven to provide extended equipment life and longer maintenance cycles, even when exposed to coal dust, salt, silica or other mineral particulate.

Rolling Bearings in ALSTOM Beater Wheel Mills

mills for pulverising coal in atmospheric steam power plants. These beater wheel mills are used to pulverise the crude lignite needed to generate steam. Hot flue gas is sucked into the beater wheel mill to dry the coal. While the coal is being pulverised, the coal dust is mixed with the flue gas, resulting in a high drying efficiency.

Construction & Mining Machinery Industrial Bearing

The bearings are easily mounted on the shaft with an adapter or un-mounting sleeve, and are used in many industrial machines for their high load capacity. Potential troubles include one row bearing no load when axial load is large, calling for attention to usage conditions.

Circular 891 Geophysical Logs as a Source of Coal Bed Data

Geophysical logs are also useful in studying the ancestoral sedimentary environments of coal beds. In the Appalachian coal region, Wanless and others (1963) used electric logs of oil and gas wells augmented by drill-hole and outcrop data to identify and map sedimentary environments of some coal-bearing rocks of Pennsylvanian age.
