Follow-up belt tensioning in mining conveyors – selection and design solutions

Wójcicki Waldemar, Wójcicki Michał

Mining Machines

2021

no. 4

12--24

The article discusses the basic dependencies of the selection of the tensioning force that guarantees the operation of the belt conveyor drive without slippage between the belt and the driving drum. The static characteristics of various tensioning systems were presented, the required forces for the given systems were determined and the influence of the tensioning method on the belt durability was determined. The paper discusses the follow-up stations in long belt conveyors operating in low inclined galleries, ensuring the reduction of belt loads in all conveyor operating conditions. Examples of solutions of follow-up stations currently operating in underground mines and their principles of operation are also presented.

The Analysis of Effectiveness of Conveyor Belt Tensioning Systems

Kulinowski Piotr, Kasza Piotr, Zarzycki Jacek

New Trends in Production Engineering

2020

Vol. 3, Iss. 1

283--293

The publication presents the evaluation of the effectiveness of belt tensioning systems based on the results of model laboratory tests. The types of tensioning devices most commonly used in industry were selected for testing: winch, gravity, pneumatic and follower. The evaluation of the efficiency of belt tensioning devices is complex, as the tensioning system is not autonomous and is only part of the belt conveyor equipment. Therefore, the publication presents the impact of belt tension force on the durability of basic conveyor components such as the belt and its joints, and drums. The characteristics of the tested belt tensioning devices are presented and the construction and research capabilities of the laboratory model of the belt conveyor are described. Measuring systems mounted on the conveyor are described in detail, enabling recording of variable conveyor operating conditions, measuring belt speed, driving force and belt stress. The results of the research are the experimental static characteristics of the most commonly used tensioning devices, which show the relationship between the drive moment and the belt tensioning force. Obtained characteristics will allow the development of guidelines for the design and selection of the most effective belt tensioning devices.
