Accurate Repeatable Primary Air and Coal Flow Rate Testing Airflow Sciences Corporation has performed extractive testing on hundreds of mills across the US. Utilizing the stateoftheart Advanced Coal Flow Measurement ACFM system, obtaining accurate and repeatable air and coal flow measurements is significantly simplified over manual extractive testing.
The primary air input to a ball tube mill performs a dual function. It is used for drying and as the fuel transport medium, and by regulating it the mill output is regulated. Governed by the pulverized fuel outlet temperature requirement, the cold air and hot air dampers are regulated to achieve the correct primary air .
2. This coal mill can reach your demand for grinding coal into flavour. 3. The primary air flow to the furnace is fed through the mill, with the purpose of heating and lift the coal particles out of the mill and into the furnace. If the the particles are too heavy they will drop to the bottom of the mill and will be pulverized once more. 4.
