The planned maintenance activities of the mining technological equipment are carried out on the principles of risk management and is done in order to prolong their duration of operation and to reduce the production cost. The quick possibilities of reducing production losses due to accidental stoppages of quarries and underground exploitation equipment, depend on the establishment and application of reconditioning methods of the subassemblies and spare parts that are frequently defects and replacement. The rotary a...

The rocks exploited in quarries have certain physical, mechanical and technological characteristics that favors the intense wear, especially by abrasion of the active surfaces of the subassemblies of the technological equipment. Some spare parts and subassemblies are subject to similar wear phenomena, as is the case with the excavators bucket teeth in the lignite pits and the loaders cup teeth in the basalt pits. In the case of the basalt aggregates which are the main raw material needed for the development of the...
