Testing Product Uniformity

Evaluation compositional product uniformity is always based on extensive sampling and sample analysis.

Sampling points:

for testing mix composition control for testing raw meal beneficiation

for testing mix composition control
for testing raw meal beneficiation

Testing Product Uniformity

Considerations before starting a sampling campaign

  • Define the characteristic to be used for judging product uniformity
  • Define the method for representative product sampling
  • Define the evaluation method

The Kiln Feed Uniformity Goals

  • Characteristics for product uniformity and   goals for excellence

Characteristics for product uniformity and goals for excellence

Product sampling

  • Considerations before starting a sampling campaign

Define the method for representative product sampling

  • Type of sample       (spot or combined)
  • Size of sample        (as a function of product granulometry)
  • Number of samples
  • Sampling frequency

Evaluation of Product Uniformity (1)

  • Possible methods of evaluation
  • Average and range
  • Standard deviation
  • Frequency response analysis

  • The Standard Deviation

Deviation from the mean are expressed in terms of the

Testing the Beneficiation Effect (1)

  • Testing the beneficiation effect of a blending/homogenizing process means comparison of the uniformity of the product fed to a process with the uniformity of the product reclaimed.

Testing the Beneficiation Effect (2)

The Blending Factor (1)

defined as the ratio of the incoming and outgoing product uniformities expressed as ratio of the corresponding standard deviations:

The Blending Factor (2)

defined as the Silo’s response to incoming compositional fluctuations expressed as frequency response of a spectrum of harmonic disturbances
