Outstanding Achievement Award :  Company founder  received the award from The University of Newcastle Key Centre for Bulk Solids and Particulate Technologies at the ICBMH 2013 conference.

120  The number of remote belt scans in the financial year 2013  to 2014 by Conveyor Technologies Pty Ltd. in USA.

ConveyorScience :  Develops software and algorithms for :

  a)   Noise removal from analog signals (all-usage software).

  b)   New fast-estimate algorithm for belt running tensions.

  c)   Safety Factor App for belts.

  d)   Software for Signal Conditioning (All-useage software).

  e)   Consulting support for Conveyor Technologies Pty Ltd.

Recent Papers :  

"A Force Balance Method" for establishing absolute  initial conditions for dynamics was presented at the 2013 Int. Conf. on Bulk Materials Handling.   The method stabilses belt dynamic simulation and prevents cumulative errors in models.

"Preventing Conveyor Belt Failure" was published in Dec. 2012 in the Australian Bulk Handling Review.   A new device to prevent splice failures, as used in USA, was described.  

"Eliminating Motor Noise from Remote Belt Scan Signals" was published in June 2013, in the Australian Bulk Handling Review.   The paper describes a new software algorithm to significantly improve data quality from remote belt scans.

24/7 Monitoring

Several companies offer 24/7 NDT montitoring devices to shut a belt down when damage is detected.  The problem is these devices offen mis-trigger regularly, or are too complex for practical protection.


Research in methods for reliable 24/7 belt control.  We are planning to trial new devices on critical conveyors using fabric and steel cord belts. 

 Watch this site for new developments.  The design will be applicable to fabric and steel cord belts.  The devices will connects to lanyard / pull-cord
systems or PLC drive controllers.   Devices will be broadly applicable and designed on a case-by-case basis.

NEWS from Conveyor Technologies Pty Ltd

Affilliated Company obtains New US and Canada Remote Scan Projects
In 2013, Conveyor Technologies Pty Ltd  added new remote scanning systems at mines in :
Ohio (84 inch belt), Wyoming (3 new scanner systems) , plus 2 more in Ontario Canada.  As of the first few months of 2014, another 2 new remote systems will be added to the Wyoming group.  A new client was added to the Wyoming list in 2015.

Underground and Drift Belt Projects :
Conveyor Technologies Pty. Ltd. (CTPL) has been non-destructively testing  (NDT)  a steel cord drift belt at Caledon's Qld mine on a monthly basis since mid-2012.   The scanning program  identifies the largest damage sites, and then in-laid cable repairs are implemented by the mine to raise belt safety factor.  The aim of the program is to ensure the drift belt continues to operate until it is upgraded to take longwall coal in 2014.

The mine will install new longwalls in 2014.   Conveyor Technologies has provided static and dynamic analysis design of the slope belt and numerous underground maingate and trunk belts.   As part of the mine upgrade, vendor proposals were scrutinized to help the mine select an EPC provider.   Conveyor Technologies provides the mine with independent engineering support and services.

In the USA
The US mining industry has been using CTPL remote NDT belt monitoring since 2001, where most large operations use the technology.  CTPL conducts approximately 100 tests a year in USA and a few in Canada.   Proven remote belt scanning technology used by USA mines over the past 15 years is also available to Australian mines   For more information  call  Paul on  +1 (307) 529-4177 or Kat on +1 {307} 529-4092.
