Belt Design

The Low Rolling Resistance belt has a modified bottom cover rubber with less hysteresis energy loss which can reduce conveyor power demand by 10%~40% compared to the conventional belt The LRR conveyor belt is also named as Energy Optimized Belt or Energy Saving Belt by different belt

conveyor belt impact resistance and the description of damage caused to conveyor purpose of the conveyor belt testing is to determine their impact resistance Since indentation rolling resistance accounts for the major part of total resistance of belt conveyor it is important to compute it using a proper method during the

The IRR is measured on a practical test rig at the Hannover Institute of Transport and Automation Technology (ITA) and it became a DIN standard in 2012 Meanwhile it has also been transformed into a European Standard (DIN EN 16974 2016 Conveyor belts - Indentation rolling resistance related to belt width - Requirements testing)

References to researchers or organizations specifically investigating rolling resistance are reviewed Two of the most commonly used design methods for first order calculation of a conveyor's effective tension are the Conveyor Equipment Manufacture's Association (CEMA) method [2] and the Deutsches Instit Normung (DIN) Standard DIN 22101 [3]

Indentation Rolling Resistance of Conveyor Belts Based on Abstract The dynamic design of a large belt conveyor with horizontal curves was studied in this paper The method of calculating its running resistance was obtained by analyzing the orienting force and resistance on the curving parts of the belt conveyors

However studies and measurements of conveyor belt resistance to motion 3 4 5 6 showed that rubber indentation was the major contributor to belt tension for long horizontal overland conveyors This led to the development of specialized low rolling resistant pulley cover rubbers that reduce energy losses from rubber indentation on idler rolls

DIN 22101

DIN EN 16974 - Conveyor belts - Indentation rolling resistance related to belt width - Requirements testing Published by DIN on November 1 2016 This European Standard defines a method for the determination of the width related indentation rolling resistance of conveyor belts

reactions and are due to 1) rolling resistance 2) sliding resistance to lateral belt forces and 3) belt cover indentation Tension dependent loss is due primarily due to 4) bulk material motion as the belt sags In addition a calculation to limit the possibility of material liftoff
