CONTROL OF STARTING MODES OF AN APRON CONVEYOR MULTI-MOTOR ELECTRIC DRIVE

Abstract

The practice of operating an apron conveyor at mining enterprises has shown that, due to their design features, they can be successfully applied in various industries for transporting a wide range of goods. Starting a multi-drive chain conveyor of large length is a rather difficult task, since this process can be accompanied by excessive relaxation of the traction body. Especially unfavorable are the conditions for starting an apron conveyor, the belt of which has sagging sections, as a result of which the rigidity of the working body, which is a function of its tension and load on it, is relatively small. In this regard, ensuring a smooth start of a multi-motor chain conveyor is an important practical task and is undoubtedly relevant for managing and maintaining a workable dynamic state of the main an apron conveyor structure operated in difficult mining and geological conditions.A method of controlling the starting mode of a multi-motor electric drive operation of an apron conveyor to ensure its smooth start and to reduce dynamic loads, to increase the service life of the traction belt and to reduce maintenance costs was developed.
