Sensors Free Full-Text Damage Detection for Conveyor Belt
The belt conveyor is an essential piece of equipment in coal mining for coal transportation, and its stable operation is key to efficient production. Belt surface of the conveyor is vulnerable to foreign bodies which can be extremely destructive. In the past decades, much research and numerous approaches to inspect belt status have been The dynamic characteristics of a belt conveyor are determined to a large extent by the properties of the belt. This paper describes experiments designed to establish the dynamic properties of belting material. The dynamic elastic modulus, viscous damping and rheological constants of the belt were measured. Several properties were studied as Dynamic characteristics of conveyor belts ScienceDirect

Belt Conveyors: Components, Types, Design, and
For applications that may require the “unorthodox” width greater than the length, type of conveyor, modular belt conveyors will achieve that feat much easier. Since they are non-metallic, easy to clean, and porous to gas and liquids, modular belt conveyors can be applied in: Food handling. Fluid handling.Large foreign object transporting by coal mine conveyor belt may lead to production safety hazards. To reduce safety accidents during coal mining, a large foreign object detection method based on machine vision is proposed in this paper.
