Summary: This standard specifies the minimum drum diameter conveyor belt calculation method. This standard applies to fabric or metal core with rubber or plastic conveyor belt. The tape cores of these tapes have different thicknesses and materials and are used under any desired tension, but can not exceed the maximum belt tension (RMBT). This standard does not apply to light conveyor belts specified in HG/T 4601.1. This standard does not apply to the core with a thickness of more than 20mm conveyor belt and fabric layer of rubber or plastic sandwich thickness of more than 0.8mm conveyor belt. This standard does not apply to the delivery of high temperature products over 100 �� heat conveyor belt and the ambient temperature below -40 �� conveyor belt. When the drum diameter is too small with respect to the core structure, it will lead to premature belt damage.

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses redrafted Law Amendment uses ISO 3684.1990 "Determination of minimum drum diameter conveyor belt" (in English). This standard compared with ISO 3684.1990 there are technical differences, the provisions of these differences have been passed in the outer margin of the page margin Set the vertical single (|) were marked, technical differences and the reasons are as follows. --- On normative references, this standard made a technical difference with the adjustment to the application of China's technical conditions, adjust the situation Concentration reflected in the second chapter "Normative references", the specific adjustments are as follows. ● Replace ISO 3.1973 with GB/T 321 equivalent to international standards (see chapters 2 and 4); ● Replace ISO 7590-1988 (see chapters 2 and 3.1.2) with GB/T 5753 equivalent to the international standard; ● Replace ISO 583.1975 with GB/T 32331 equivalent to international standards (see chapters 2 and 3.1.1); ● Replace ISO 21183-1 (see Chapter 1) with HG/T 4601.1 equivalent to the international standard; ● Remove the ISO 1536.1975 code (see Chapter 2); --- Modify the title of Chapter 3, the addition of terms and definitions of lead (see Chapter 3); --- Modify the letter indicating the thickness of the fabric layer and the thickness of the rope (see 3.1). This standard also made the following editorial changes. --- Incorporation of International Standard Amendment (ISO 3684.1990/Amd.1.2006), at the same time in the modified terms of the margin outside the margin page Set with vertical double line (‖) mark; --- Removed the first chapter "Note 3"; --- Correct "Belts" in the ISO 1536 standard name to "Beltpuleys"; --- Number of the formula. This standard proposed by the China Petroleum and Chemical Industry Federation. This standard by the National Belt and Belt Standardization Technical Committee Conveyor Belt Technical Committee (SAC/TC428/SC1) centralized. This standard was drafted unit.

1 Scope

This standard specifies the minimum drum diameter conveyor belt calculation method. This standard applies to fabric or metal core with rubber or plastic conveyor belt. The tape cores of these tapes have different thicknesses and materials at Use under any anticipated tension, but not exceed the maximum belt tension (RMBT). This standard does not apply to light conveyor belts specified in HG/T 4601.1. This standard does not apply to the core thickness of more than 20mm conveyor belt and fabric layer of rubber or plastic interlayer thickness of more than 0.8mm Conveyor belt. This standard does not apply to the delivery of high temperature products over 100 ℃ heat conveyor belt and the ambient temperature below -40 ℃ conveyor belt. When the drum diameter is too small with respect to the core structure, it will lead to premature belt damage. Note 1. The values given in this standard are the minimum values used in the absence of the corresponding values provided by the conveyor manufacturer. Note 2. The minimum drum diameter calculation method given in this standard applies to all general conditions of use. Conveyor belts manufacturer may be used under special conditions It is permissible to use rollers of a diameter less than the minimum diameter determined in accordance with this standard.
