Description
Technical field
The utility model belongs to medium-speed pulverizer accessory applied technical field, and in particular to is applied to thermal power plant middling speed
The metal ceramic compound wear resistant liner plate of coal pulverizer, wear-resisting, high temperature resistant, long service life, and be easily installed and demolition and maintenance.
Background technique
Coal pulverizer is by coal crusher and to wear into the machinery of coal dust, it is the important ancillary equipment of coal-powder boiler, is had vertical
The Multiple Types such as flour mill, high-pressure overhang roll mill, middling speed micropowder grinding, super-pressure trapezoidal mill, Raymond mill；Massage the revolving speed of coal workpiece
Three types, i.e. low-speed coal mill, medium-speed pulverizer and high speed coal mill can be divided into.
Low-speed coal mill, predominantly drum-type low speed coal mill, general abbreviation ball mill or ball mill, it is a rotation
Cylinder or both ends be taper roller, roller is provided with steel ball, and the revolving speed of roller is
15~25 revs/min, steel ball when work in cylinder constantly hits and squeezes coal cinder, and coal pulverizer coal cinder is ground coal-forming
Then coal is dried by the hot wind being passed through in roller and sends out coal dust by powder, after separator separates, the coal dust quilt of certain particle size
It is sent into pulverized coal bin or is sent directly into coal burner, ball mill bulky, power consumption are high, noise is big, but to the adaptation model of coal
Enclose it is wide, reliable for operation, particularly suitable for grinding hard anthracite.
Medium-speed pulverizer, revolving speed be 50~300 revs/min, type is more, common are square position mill, bowl shaped mill, E type grind and
Roller mill, their common feature are that component of milling is made of the milling body of two groups of relative motions,
Coal cinder is squeezed between this two groups of milling body surfaces, mills and is crushed, while being passed through the hot wind of coal pulverizer
Coal is dried, and coal dust is sent in the separator on area top of milling, the coal dust of certain particle size takes mill out of with air-flow after separation
Outside, the coarse grained coal dust backspace area that mills is refaced, have facility compact, take up little area, power consumption save (about the 50 of low speed coal mill~
75%), noise is small, the lighter remarkable advantages such as sensitive of operation control.
High speed coal mill, revolving speed are 500~1500 revs/min, are mainly made of high speed rotor and mill shell, common are fan
Mill and hammer swing sledge mill etc., in coal cinder in fan mill by mutual between the high speed impact of high speed rotor and the collision of mill shell and coal cinder
It hits and is grated, this coal pulverizer forms a whole with coal dust classifier, and structure is simple, and compact, initial cost saves, especially suitable
For grinding, high water content brown coal and volatile matter are high, are easy the bituminous coal ground.
In above-mentioned medium-speed pulverizer work, since coal charge etc. can all cause impact, mill to lining plate of coal grinder in work
Damage, so more demanding to the liner plate being mounted in coal pulverizer.But the liner plate of existing structure, high temperature resistant, impact resistance and resistance to
It is poor to grind performance, causes service life is short need to often shut down, detect maintenance, low, increase production cost of working efficiency etc. is caused to ask
Topic, has been unable to meet the work installation requirements of existing thermal power plant coal pulverizer, and this is current urgently to be resolved.
Therefore, based on the above issues, the utility model provides the cermet for being applied to thermal power plant medium-speed pulverizer
Composite abrasion-proof inner plate.
