WELCOME TO THE CONVEYOR BELT GUIDE!
Dear Conveyor Belt User,
The intention of this site is to provide practical information about heavy duty conveyor belts, which normally is not found on commercial web sites.
The ConveyorBeltGuide is permanently growing and improving. You are kindly invited to send your comments or questions. With your support this guide will become better for the benefit of all who are working with this great product.
The ConveyorBeltGuide was launched in September 2003, and it got a facelift in July 2016, after 13 years.

Pathbreaking belt monitoring
Nonstop conveyor belt monitoring based on X-ray technology is about to revolutionize long distance conveyor belt performance. Virtually every cubic millimeter of a conveyor belt is scrutinized. It is the perfect part of Preventive Maintenance and Industrial Internet of Things. More...
New requirements in China's coal industry
Subsequent to a decree of May 2013, according to which main steel cord conveyor belts have to be equipped with a belt and splice health monitoring device, a further tightening is coming into force: As of October 2016, all belt conveyors must be equipped with a rip detection device.
China is by far the world's largest consumer of conveyor belts.
Contitech has stopped their conveyor belt production in Volos, Greece (the factory was also known as "Imas") in March 2016. 138 employees were laid off. The inventory is for sale.
The same fate strikes their plant in Bowmanville, Canada.
Their steel cord belt plant in Brazil is for sale.
An Australian standard for the indentation rolling resistance is under development and expected to be published early 2017.
ISO 7623, published in October 2015: Steel cord conveyor belts - Cord-to-coating bond test.
In November 2015, revision of EN DIN 12882, and in October 2015, revision of DIN 12881-1 have been released.
A new record length belt at a project in South Africa has been commissioned in 2015. The single-flight conveyor is 27 km long. It is a 1200 / St 2000 7/5 belt. More...
Revision of DIN 22129 part 4, splicing, published in August 2015.
Revision of AS 1755
In 4Q15, Australia's current conveyor safety standard AS1755 will be superseded by a series of new standards under AS4024, where part 3611 will cover belt conveyors for bulk material handling.
Germany's Continental/ContiTech has taken over US based Veyance Technologies, effective on 30.Jan.2015, creating world's biggest conveyor belt manufacturing group, eliminating Goodyear/Veyance from the conveyor belt market.
The new 7th edition of the CEMA handbook has adapted the calculation principle of DIN 22123.
We have added a video on so-called "man-riding", practiced in Germany.
The revised DIN 22102 for textile conveyor belts has been published in January 2014.
First standard for indentation rolling resistance of conveyor belts - DIN 22123
This first-time standard has been published in October 2012. More about IRR...
One component adhesive
A new kind of adhesive for cold splicing and repairing of conveyor belts has been launched. This one-component glue makes warehousing and dispatch easier, no activation is necessary, errors by wrong dosage of activator are eliminated, there is no vulcanization in the tin.
Draft revised standards published
E DIN 22109-1 (2013) - Solid woven textile conveyor belts for hard coal underground mining
E DIN 22109-2 (2013) - Two-ply textile conveyor belts for hard coal underground mining
E DIN 22109-4 (2013) - Two-ply textile belts for hard coal above ground use
E DIN 22110-3 (2013) - Dynamic splice test
E DIN 22121 (2013) - Textile belt splices for hard coal underground mining.

Are booster drives the way to go?
For decades, intermediate drives in long conveyors - so-called booster or TT drives - have been used to bring down the peak belt tensions, subsequently allowing for smaller belt ratings.
Just recently, some papers promoting this old idea have been published. We also see several new conveyors employing such extra drives.
However, the negative side of additional drives are higher investment, lower availability, more maintenance and faster belt wear.
A smarter way resp. the first choice could be to design the conveyor belts as per DIN 22101 (2002 or 2011 issues) employing state-of-the-art dynamic splice efficiency, reducing the belt rating and bring down costs, also for other conveyor parts, substantially.
A paper called "State-of-the-art long distance conveyor belt design" published in Coal Asia Magazine describes this.
