Ways of solving problems of abrasive effects of transported materials on technological lines for raw mineral processing

The article analyzes systems of transport tracks on technological lines for processing of raw materials on selected quarries of the Czech Republic and the Slovak Republic. It deals with the functionality of the technological equipment in relation to the movement of raw material within these technological lines, it introduces and compares various systems of raw materials transferred to the long-distance transport of raw materials between the technological department softening organizations. It brings different views on how to deal with the negative effects on the lifetime of individual parts of technological units. It deals mainly with the problems of abrasion on raw materials transported and the problems of abrasive influences of fine particles in the process of extraction of individual nodes of the technological line. The article provides possibilities for more efficient maintenance of this equipment, financial savings in subsequent pairs and a view of the application of modern materials such as UHMW-PE, polyurethane, teflon, wear protection rubber. By combining the anti-abrasion protection systems of the technological equipment, significant savings can be made in the maintenance of aggregate processing technology.
