Primary air provides the means to dry, classify, and transport the coal from the grinding zone of the mill through the classifier PF pipes to the furnace Two constraints for the PA flow are: Ability to maintain the minimum air velocity (1516 m/sec) to transport the coal To maintain the correct air .
Preliminary investigation on the effects of primary airflow to coal . mill at coalfired power plant in Malaysia. Coal flow distribution were sampled from the vertical straight PC pipes just after the pulverizer by using Dirty air pitot (DAP) and Pulverized Fuel Sampler (PFS) to measure the flow velocity and extract coal samples [8].
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.

INTRODUCTION TO BOWL MILLS: Coal is the one of the most dominating energy source because of its cost, availability and transportability. Pulverized form of coal has made modern steam generating units highly thermal efficient, reliable, safe and able to efficiently use of lowgrade coals.
The mill system consists of coal feeders, crusher dryers, standalone centrifugal static classifiers and a ball tube mill. Raw coal from the feeders is mixed with hot primary air and then fed to crusher dryers. After primary crushing and initial drying with the crushers, the crushed coal is fed into the mill .
