Longitudinal tear mine conveyor Analysis and Prevention
The traditional structure of conveyor belt, between the cover and the addition of a different frame structure, the tear layer of different materials to meet different environmental requirements. In the skeleton on the cover layer and into the high-strength nylon rope between the steel mesh or wire rope to increase the strength of the conveyor, so that debris is not easy to pierce, even if punctured or torn, the conveyor belt in a horizontal reinforcement resistance cumulative effect. When the resistance increased to a certain limit, will cause motor over-current shutdown. Tear, compared with an ordinary belt,
MBTシューズ 販売店, impact strength, tear resistance, and some other physical properties have improved significantly. 3 tear-resistant conveyor belt (1) tear tear steel cord conveyor belt conveyor belt structure is a complex production process, high-tech products. The vertical conveyor is a galvanized steel wire rope for the matrix material, the band added to the body as the tear layer of horizontal reinforcement, the layer structure is divided into two kinds: the use of hanging plastic mesh (steel mesh or fiber mesh cloth ); the use of horizontal rope (rope or synthetic rope). As the only common around the vertical steel cord conveyor belt arranged alternately twisted wire rope as a skeleton, did not enhance horizontal layers, so prone to use the process of vertical tearing. To further strengthen the steel cord conveyor belt tear, impact resistance, added in with the body as the tear layer of horizontal reinforcement,
knock off oakleys, theoretical and experimental tests prove that transverse tensile strength and tear resistance, as a horizontal wire rope enhancement layer is superior to synthetic ropes, synthetic ropes, but flexibility is good, there is a certain superposition of the role, impact resistance is better. Horizontal wire mesh and different structures, the enhancement layer mesh structure due to the formation of network structure, mesh structure on the conveyor belt tear strength, impact strength have some cumulative effect. (2) tear-resistant conveyor belt performance indicators to measure the performance of key indicators: Nominal tensile strength, abrasion resistance, tear strength, impact strength. For steel cord conveyor belt, the main carrier for the vertical stretch the rope,
ed hardy canada, the tensile strength of different nominal conveyor select a different diameter, different structure for the skeleton of steel wire rope wire rope; wear resistance is mainly determined by the performance and plastic cladding thickness; and transport with tear strength, impact strength of many factors. Such as the transverse diameter and spacing of wire rope; plastic cladding performance and thickness; longitudinal wire spacing and so on. With the main purpose is to tear through the body without adding buffer or enhance the parts,
true religion outlet, to enhance the tear strength, while improving its impact strength. 4 Conclusion a vertical conveyor belt tear through the analysis of the reasons put forward some measures to solve. Conveyor belt to prevent tearing the accident result in tearing the scene apart from eliminating all risks, and improve all aspects of facilities, to strengthen the operation and maintenance worker safety education,
Salvatore Ferragamo outlet, the implementation of personal responsibility and improved management structures, strengthen site management , to prevent tearing accident that these measures can also lead to better delivery through the use of tear-resistant conveyor belt to solve the problem of tearing in order to better serve the coal mines to improve coal mine production safety.

The system is a device for the production department of a large number of records management work and development. According to production manager requirements for device management of all aspects of the file. Basic overview of the table by an input device, equipment procurement program management table, table equipment, inventory management, information management table manufacturers, equipment maintenance records and other basic information table, the system itself generates the appropriate types of statistical reports for production managers query, print; In addition, the production manager can also basic information on these regular updates, and deletes. Parallel way, so that a smooth hand-account, switch to the development of reliable mechanical and electrical equipment to computer management system. In addition, because the system needs information on the Internet and business inquiries contact manufacturers, software running on the system environment requirements accordingly.
