Nov 14, 2019· What are coal feeders? Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace).. The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.
The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.

MERRICK Coal valves are utilized as material shutoff gates located at the bunker (silo) outlet. These valves provide "off-on" control of the material of varying sizes. They are designed to cut through a standing column of material.
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 low-grade coals.
Our rotary airlock valves are used in a wide range of applications where there is need to minimize system air loss while transferring material between vessels with differing pressures. They are used as feeder valves to meter the flow of material between vessels with equivalent pressures. You will also find them doing double
on 70% of the coal passing through a 200 mesh screen. Mills are capable of grinding harder coal with higher percentage moisture content and can reduce the product fineness in excess of 90% passing a 200 mesh screen at a reduced output capacity. The feed size of the coal to the mill should be pre-crushed to 1" top size. Available capacity size
