Don Suverkrop has been involved in a number of incidents where out of court settlements exceeded $20,000,000 each. (Not a word appeared in the newspapers. These deals are contrived in confidentiality agreements worked out on court house steps.)

Belt conveyors must operate under wide variations of load, temperature, stopped, acceleration, running, deceleration, fatiqute, etc. Belt tension under all these conditions must be sufficient to convey yet avoid the momentary lapses that result in spillage that invites the taking of a life, limb or causes the overstressing of a component that precedes a system shutdown.

WINBELT HAS BEEN ATTACKING THESE PROBLEMS WORLDWIDE SINCE 1985.


Existing Belt Conveyors Require Fine Tuning.

The “belt conveyor engineer/technician” performing “fine tuning” must be well grounded
in the causes and effects of belt conveyor defects.

A dam contractor was faced with a looming $27,000,000 penalty charge.

Don Suverkrop was retained to recommend improvements that by increasing the conveying rate would enable the contractor to avoid this charge.

Don made a video of his “walk around”.  This video has become both a learning tool and a test for grading “belt conveyor technicians”.  Join him for a “walk around”. 

View the videos on the right and the supplemental videos and rate yourself.   See how many defects you can identify that are  reducing conveyor capacity and yet can be expediently adjusted or altered to increase conveying rate.

How  many of these defects did you identify?

a) When loaded the belt is not centered on the  troughing idlers.  This is evidenced by seeing more troughing idler roll exposed on one side when compared to the other side.   This reduces the cross sectional area of the material being conveyed.

b) Unsymmetrical material transfer points.  Material striking the belt at angle applys lateral force to belt.   (contributing cause of a)

c) Center of material mass not centered in material width.  An effect due to a previous transfer imperfection. (No conclusion)

d)  Splice failures.  See DVD 100.  These caused several total shutdowns. 

e) Return belt  off side as it approached the tail pulley.   (Not visible in DVDs.  This was observed by crawling under the conveyor)

 f) Installed troughing training idler(s), training effect insufficient.

h) Hydraulic takeup controlled by  booster drive T2 tension. Unknown training effect.  (Conventional VGTUs tend to train return belt. )

Conclusion:  The writer assumed  that b) caused the condition a) that was not rectified at  e)  and that  a  powerful training effect was required to ensure the belt was properly centered at the loading point e). 

Reconstructing chute work was not an option in view of the time required
to do so.

Recommendation:

1-Tilt all troughing idlers toward head pulley with one flat steel washer  under each side farthest from head pulley.

2-Install 200 feet (or an extensive number of) return side training idlers near tail.

With these recommendations  the spillage problem was sufficiently corrected that the contractor was able to increase the conveying rate. The project was completed on  time.  $27,000,000 was thus saved!

How well did you do on the test?  Did you save the $27,000,000?
