HISTORY

ConveyorScience.com  domain name was founded in the USA in 2001.

The website was originally formed under its parent company Scientific Solutions Inc. in USA.   Members consisted of  Conveyor Technologies Ltd LLC  and Dr. Alex Harrison as Organizer.

Scientific Solutions Inc (SSI)  owned and developed technology for the coal and ore mining industries, worldwide.   Founded in Denver, Colorado, USA in 1993,  SSI provided services wordwide and in the USA under Conveyor Technologies Ltd. LLC (CTL).   CTL serviced the North and South American mining industry.   In 2011, SSI and CTL's US operations reformed as Conveyor Technologies Pty. Ltd. (CTPL) owned by Dr. Harrison in NSW, Australia.

T
he original www.ConveyorScience.com was a website hosted by Network Solutions Inc. in 2001 in the USA until it was migrated to new Australian Domain Holders in 2011.   www.conveyorscience.com is owned by Dr. A. Harrison, resident in Australia after 25 years in Denver CO, USA.

Consulting on coveyor matters can be proviided through CTPL or CBMI.com.au, or via the Newcastle University company TUNRA Bulk Solids for collaborative projects in conveying and bulk handling.

Research Activity includes :

   O - Software development for conveyor design and design audits : Mechanical engineering analysis is developed in-house using software and algorithms written specifically to compute rolling and other losses in a conveyor so that belt ratings and installed drive torques are adequate to move the bulk material at the desired speed. Analysis of horizontal curve friction is available, as is the analysis of pipe onveyors.

 O - Dynamic analysis simulation of long conveyors.  Elastic and inertially driven belt stress waves are computed for a given design to determine the high and low belt tensions in the design, the take-up requirements and its location, and any other dynamic condition such as drive slip is studied in detail.

Some Conveyor ​Firsts

The 80's  -  Company founder invents worlds first non-destructive testing system for monitoring steel cord belts while working as an Experimental Scientist at CSIRO Division of Applied Physics in Lindfield, NSW (known as the Conveyor Belt Monitor or CBM).  The company founder left CSIRO as a Principal Research Scientist after 10 years, and was appointed Professor of  Engineering at Newcastle University in 1989.  In 1993  Conveyor Technologies Ltd. LLC was founded in the USA. 

1982  -  First publication of the S-curve optimisation for conveyor starting.  Developed the mathematical proof that an "S-Curve" cycloid for the starting (or controlled stopping) velocity of a conveyor belt resulted in the minimum dynamic stress based on the mathematical "Principles of Variation".   First publihed in South Africa 1982 (Beltcon 2),  titled "Minimizing Transient Stresses in Conveyor Belts". 

1983 - 1984  -  First derivation of the 4-th order Partial Differential Equations describing and predicting belt vibration modes and frequencies using an axially-tensioned orthotropic steel-cord and rubber plate composite.   The topic is used as a basis for all ongoing vibration analyses in idler supported belts.  Alex Harrison was awarded a PhD for the research in 1984 (Newcastle). 

1984 - 1986  -  Australian and US Patents on belt scanning by company founder. 

1986  -Company principal at CSIRO develops the Fabric Belt Monitor (FBM) to measure di-electric variances in non-steel belts.   Papers published. 

1986  -  Company founder was the first to derive the closed-form mathematical equations for  induced strains at a damage site in corded composites.  This was not a FE Finite Element method.  Paper published in the British Journal of Strain Analysis (1986). 

The 90's Onwards

1990  -  Company founder.develops non-linear vibration theory of belts, demonstraing some of the earliest-known concepts in Chaos Theory.   A paper on belt vibration and Chaos Theory was published by the Royal Society Phil. Transactions, England. 

2000  -  The first Remote Real-time NDT belt monitoring began using signal processing algorithms developed by Scientific Solutions Inc. in USA. 

2006  -  A new high-speed simulation algortithm developed for forward-prediction of convergent dynamic stress in belts.  A mechanical simulation model developed. 

2007 - 2015  -  R & D on NDT software, remote monitoring, noise reduction codecs.

2015 - :  CTPL operated independently from Dr. Harrison a nd has expanded its operations with cbmi Pty Ltd.
