The
UCC commitment to quality is backed by thousands of hours of development,
testing and evaluation. United Conveyor Corporation has one of the
world's most advanced research laboratories and conveyor test loops to simulate
ash and reagent handling applications and validate design parameters. Our
knowledge and experience in material behavior, product innovation and system
development for challenging applications is unmatched in the industry.
UCC works closely
with our global customers to test and verify conveying performance before
deployment at the plant to effectively manage risk.
Technology
Our test lab provides
UCC’s NPD team with the capability to engineer prototypes and continually test
new products and equipment to enhance existing designs. This ability
enables our engineers to develop state-of-the-art technology, providing our
customers with superior products and custom solutions they’ve come to expect
from us.
Material Testing
Hundreds of ash and
reagent samples have been tested and analyzed in our 10,000 sq. ft. lab to
ensure material performance and reliability. This testing environment
allows for complete analysis of physical, chemical and conveying
characteristics of material.
Testing
Includes:
- Bulk Density
- Particle Density/Specific Gravity
- Fluidizability
- Sieve Size Distribution
- Laser Diffraction Analysis for particle size
distribution of powders
- Microscopic Examination with Digital Photography
- Setup/Conditioning
- Pick Up Velocity
- Arching/Rat holing Index
- Permeability/Deaeratability
| - Moisture Content
- LOI or Unburnt Carbon
- Thermo Gravimetric Analysis (TGA) for analyzing
chemical compounds
- Scanning Electron Microscope (SEM) Analysis/Photography
- Energy Dispersive Spectroscopy (EDS)/X-Ray
fluorescence (XRF) for analyzing elements
- Rheology of low/high density slurry
- Free-lime test
- Water tests – Langelier’s index, Ryzner stability
index, Aggressiveness Index

Test Loops
Our facility contains
six complete test loops which are used to simulate the behaviors of material in
conveying lines under various conditions. Control systems are used to
examine and control the conveying environment, and comprehensive data is
collected and provided to verify determining design parameters.
