SCIENTIFIC AND TECHNICAL SUPPORT AT THE DEVELOPMENT OF REGULATIONS FOR MAINTENANCE AND REPAIR OF CRUSHING ENGINES

Abstract

Over the past few years, Institute of Mining of the
Ural Branch of RAS has developed regulations for the
system of technical maintenance and repair of cone
crushers of small, medium and large crushing, as well
as jaw crushers with a simple cheek swing. Preparation of complex regulations for technical maintenance
and repair (TMR) for any type of equipment, taking
into account differentiation by operating conditions,
reflecting the structure of the repair cycle, reasonable
frequency and volume by type of TMR, the service life
of components and parts, as well as operational
standard technological maps of TMR performance, is
a complex task that requires the collection and systematization of large amounts of statistical data. It
also needs taking into account many factors that affect the operational reliability of equipment, the required frequency and volume of repair work. Such
regulations are developed for high-quality and timely
maintenance of crushers, for maintaining them in
good operating condition, and they allow us to reduce
TMR costs, to extend the service life of components
and mechanisms, to improve the skills of repair personnel, and to plan the consumption of spare parts.
Each regulation developed by Institute of Mining of
the Ural Branch of RAS reflects specific parameters
of the repair cycle, configuration of the technical
maintenance and repair system, and takes into account the operating conditions of crushing equipment,
including the properties of rocks, the spare parts and
materials used for repairs (in particular – locally
produced), the operating mode of equipment and the
intensity of its use, etc.
The article presents the main issues that arose during
the development of such regulations for TMR and
developed methodological approaches to their elaboration by the Institute of Mining of Ural branch of
RAS. The requirements for modern TMR regulations
for mining equipment, which should be taken into
account when developing them, are described.
