ASGCO® Engineering Design, Point Cloud Scanning Technology, Chute Fabrication, Syntron Feeders and Product Installation Provide Complete Turnkey Service at This Eastern Coal Fired Power Plant.

Challenge:  The older existing feeder was clogging and not producing enough product flow to
supply the operation. The objective was to restore and control the material flow from an above
ground surge to the underground conveyor belt that feeds the power plant. The conveyor
descended down an incline into a narrow underground tunnel making movement difficult.
The existing heavy feeders and knife gate needed to be removed but getting over the obstructions
(such as existing equipment, detouring around piping and railings) was extremely challenging.
In addition, five to six layers of stainless steel liners in the surge pile that feeds into the hopper
had to be trimmed and cut in order to fit the new hopper against the ceiling.
The need for accuracy in the design and prefabrication of the feeder system and chutes
to fit the existing structures was extremely important to meet the plant’s capacity
flow of 300 TPH of 2” minus coal.

Solutions:  ASGCO® engineers would provide an onsite Point Cloud Scanning survey to provide
accurate measurements of the facade and structures. A 3D model would then be developed of the hopper,
chute and vibratory feeder system and then overlaid into the Cloud Point Scan to check for interferences.
On this project an XPMF-200 Syntron Direct Drive Electromechanical Feeder with VFD Controller
in a Nema 4/12 enclosure, would be designed and installed to replace an older existing feeder and meet
the capacity needed. Also a Remote Control Box with manual potentiometer and start/stop buttons in a
Nema 7/9 enclosure would be provided for remote mounting. ASGCO®’s Fabrication shop would then
fabricate the new hopper and chute and line it with Nitronic SX™ wear liners to create a surface
that would work harden and have a low coefficient of friction. A Safe-Guard® Conveyor Chute Inspection
Door installed on the chute would offer safe inspection and clean out. 

Results: ASGCO®’s installation crew of four (4) people, was able to remove the old feeder and knife gate
and install the new Syntron Vibratory Feeder and fabricated chute and hopper. The customer is now
experiencing the desired rate of material flow to supply their operation and they no longer have to stop
operations due to blockages.
