Methodical approach to the development of regulations of maintenance and repair of crushing equipment of mining companies

Crushing equipment is one of the key for mining enterprises, as it provides ore preparation for subsequent mineral processing. Recently, the issue of increasing the productivity of the crushing site at existing enterprises without radical reconstruction is relevant. The solution is the installation of high performance crushers and the optimization of the maintenance and repair system in order to ensure maximum availability and utilization in time. The article presents the experience of developing a methodology for constructing a strategy for maintenance and repairs (MRO) for crushing equipment. The experience of developing technological routine MRO for crushers manufactured by PJSC Uralmashzavod was taken into account.The problem of the collection, processing of source data and their analysis is considered to obtain reliable statistics on the time between failures of parts and components of crushers.Reflected are the features of the analysis of data on the operating time of assemblies and parts for failure during the service life for various operating conditions.Differentiation of the operating conditions of crushing equipment at mining enterprises is considered, which made it possible to formulate standardized repair cycles for several groups of operating conditions.A technique has been developed to form the structure of repair cycles of crushing equipment.Options for choosing a strategy for building a repair cycle are proposed. The quantity, periodicity and composition of MRO are determined.
