Product catalog summary
Product Overview
The Ash Moisture Analyzer (AMA-D) is a device developed by DFMC for on-line detection of coal flow on conveyor belts. It is designed to improve sampling representativeness and can be used in various coal-related industries for inspection and process control.

Product Principle
The AMA-D measures ash content using double energy γ-ray transmission and moisture content using microwave transmission. The calorific value is calculated based on the ash and moisture values.

Product Parameters
  • Accuracy:
    Clean coal: ≤ 0.5%
    Raw coal with low ash content: ≤ 1.0%
    Raw coal with high ash content: ≤ 2.0%
  • Moisture Measurement Accuracy:
    5%–10%: ≤ 0.5%
    10%–20%: ≤ 1.5%
    More than 20%: ≤ 2.0%
  • Thermal Value Reference Accuracy:
    Clean coal: ≤ 100Kcal/Kg
    Raw coal with low ash content: ≤ 150Kcal/Kg
    Raw coal with high ash content: ≤ 200Kcal/Kg

Product Characteristics
  • Real-time Analysis: Provides instantaneous and average values of coal ash in real-time.
  • Representative Measurement: Analyzes all coal on the belt, overcoming traditional sampling limitations.
  • Adaptability: Utilizes non-contact measurement through signal penetration.

Product Application
The AMA-D is applicable in coal mines, washery, blending, coking plants, power plants, steelworks, and coal wharfs for on-line measurement and process control.

Ash Moisture Analyzer-1

1. Produce Overview The Ash Moisture Analyzer (AMA-D) independently developed by DFMC is directly installed on the coal conveyor belt and directly performs on-line detection of the whole coal flow, avoiding the problem of poor sampling representativeness. It can be widely used in coal mines, thermal power plants, coal washery, coal blending plants and coal terminals for on-line inspection, and can also be used for automatic adjustment and control of the production process in coal preparation and coal blending processes. 2. Product Principle ■ Ash measured by double energy y-ray transmission ■ Moisture measured by microwave transmission ■ Calorific value calculated by ash/moisture value 3. Product Parameters ■Accuracy Clean coal < 0.5% Raw coal with low ash content < 1.0% Raw coal with high ash content

■Accuracy of moisture measurement 5%—10% < 0.5% More than 20% < 2.0% ■Thermal value reference accuracy (specific accuracy is given based on site conditions) Clean coal < 100Kcal/Kg Raw coal with low ash content < 150Kcal/Kg Raw coal with high ash content < 200Kcal/Kg 4. Product Characteristics ■ Real-time analysis: The detection of the coal flowing through the belt is totally real-time. The analyzer can give the instantaneous value and average of coal ash within any time period according to the needs. ■ Representative measurement result: The analyzer analyzed all the coal flowing through...
