introduction

Steel cord conveyor belts are generally quite long, therefore it is necessary to connect the several sections of conveyor belt provided by the manufacturer at the application site. To ensure that the joints between conveyor belts provided by manufacturers have high dynamic performance, it is necessary to standardize certain characteristics, such as... Such as the thickness of the core layer, the spacing between the wire ropes, and the diameter of the wire ropes. Based on the specific circumstances of the domestic steel cord conveyor belt industry, steel cord conveyor belts include structural design, belt type, underground safety requirements, and The vulcanized joint consists of four parts, which are related yet independent. GB/T 28267 is proposed to be composed of four parts. ---Part 1.Design, Dimensions, and Mechanical Requirements for General Purpose Conveyor Belts. The purpose is to provide information to stakeholders of steel cord conveyor belts. Provide standardized structure and performance specifications to improve the interchangeability of steel cord conveyor belts and facilitate maintenance and replacement. ---Part 2.Optimal Belt Type. The aim is to facilitate mass production of steel cord conveyor belts and standardize downstream conveyor equipment. Standardization. ---Part 3.Special Safety Requirements for Conveyor Belts Used Downhole. The purpose is to standardize the use of wire rope core conveyors in special downhole environments. The safety features of the belt. ---Part 4.Vulcanized Joints of Conveyor Belts. The aim is to provide standardized joint requirements for stakeholders to improve the service life of conveyor belts. life. Steel cord conveyor belts, Part 2.Preferred belt types 1.Scope This document specifies the preferred belt types for designing steel cord conveyor belts. The preferred belt type series specified in this document is based on... The structural requirements specified in GB/T 28267.1. This document applies to steel wire rope conveyor belts.
