A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
The socalled micro coal refers to the coal powder meeting the standard of fineness after coal is ground by grinding mill. Through the technology of micro coal atomization, the fuel can mix with air fully to form a rotary vortex and then the fuel enters the industrial boilers and burns in suspension inside.
A Discreet Element Model (or DEM) of a tube mill. The DEM was done to determine the profile of the grinding balls and raw coal for a full tube mill CFD study. The profile will be mapped as a .
Then the coal is fed into the grinding cavity of LM130M vertical mill by quantitative belt conveyor. After being ground, the coal gets pulverized and enters to the antiexplosive impulse dust collector in the wake of powder separation. Then, the collected finished coal powder is sent to the storage hopper through pneumatic conveying system.
With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to % or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of .
Coal Mill. Coal mill, which is also known as coal grinding mill or coal milling machine, is used to pulverize and dry coal before it is blown into the power plant furnace in the coalfired power mill is an important auxiliary equipment for coalpowder furnace, it has three methods to crush the coal lump and grind them into powder,it is crushing, impacting and grinding.
Coal, lignite or petcoke are ground in the Pfeiffer vertical mill by using hot gases from a hot gas generator. The grinding plant can be inerted. The raw coal is dried while being ground in the mill even if feed moisture exceeds 25%. The feed size that can be handled is up to 100 mm, making twostep precrushing unnecessary.
This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coalfired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.
The series of benchmark testsvariation of classifier settings; variation of air rates; variation of feed rate and coal typeson the ball and race mill were continued. The wet ball mill grinding system was operated in open circuit, first grinding coal in No. 6 fuel oil and then grinding coal in water.
