The grinding room comprises an airflow inlet 1, a material inlet 2 and a grinding room cavity wall, wherein the grinding room cavity wall is provided with a composite lining material 4, the composite lining material 4 is formed by tightly connecting a ceramic lining layer 42 and a shell 44 from interior to exterior, the ceramic lining layer 42 is formed by multiple small ceramic chips, an organic material coating 41 is covered on the outer surface of the ceramic lining layer 42, and the ceramic lining layer 42 is tightly connected with the shell 44 through an organic material coating layer 43. According to the utility model, by adopting the composite lining grinding room capable of combining the ceramic lining layer 42 and the shell 44, the structure is simple, a high-purity alumina material used for the ceramic lining layer 42 is wear resistant and anti-corrosive, and is free of pollution on a crushing material in a grinding cavity, the quality of a processing product is effectively ensured, the ceramic lining layer 42 is formed by multiple small ceramic chips 3, and the grinding room has the advantages of easy processing, difficulty in crack and the like.
Description
Technical field
The utility model relates to the grinding chamber of airslide disintegrating mill, particularly a kind of composite ceramics liner grinding chamber of airslide disintegrating mill.
Background technology
The fluidized bed type airslide disintegrating mill is to utilize high velocity air to realize the equipment of dry solid material ultra-fine grinding; Main workpiece is a grinding chamber in the airslide disintegrating mill, is provided with the high pressure admission nozzle in the grinding chamber cavity, forms high velocity air through purifying with dry compressed air from the nozzle entering; Solid material is under the drive of high velocity air; In grinding chamber, pulverize through severe impact, collision, friction, to grading wheel, coarse granule quilt under centrifugal action is thrown to the grinding chamber barrel to air-flow with the powder conveyance of pulverizing; Falling back to pulverizing chamber continues to pulverize again; The powder that meets fineness requirement is delivered to separator through grading wheel, so moves in circles, and material constantly grinds in grinding chamber and attenuates.
The grinding chamber cavity wall washes away through gas-solid mixing high velocity air repeatedly, can wear and tear in the surface, and the particle diameter of solid material is big more; Hardness is big more, and is also big more to the wearing and tearing of grinding chamber cavity wall, and corresponding stream pressure is big more; It is big more that gas-solid mixes back kinetic energy, also big more to the wearing and tearing of grinding chamber cavity wall, the above situation; The used material material of grinding chamber cavity wall can form pollution to material because of wearing and tearing get into the material the inside, causes product quality to descend, and increases production cost.
The utility model content
It is a kind of simple in structure, wear-resisting that the purpose of the utility model is to provide, and comminuting matter do not produced the composite ceramics liner grinding chamber of the airslide disintegrating mill that pollutes.
A kind of grinding chamber of airslide disintegrating mill contains air-flow air inlet 1, material inlet 2 and grinding chamber cavity wall, on the grinding chamber cavity wall, is provided with composite lining material 4, and this composite lining material 4 is from inside to outside closely connected to form by ceramic member inner liner 42 and shell 44.
Said ceramic member inner liner 42 outer surfaces cover coating of organic material 41, are connected with coating of organic material 43 between ceramic member inner liner 42 and the shell 44, and said organic material can be an epoxy resin.
The thickness of said coating of organic material 43 is 2mm～4mm, and said coating of organic material 41 upwards extends below at two ends, and 42 liang of end surfaces of ceramic member inner liner and shell 44 seam crossing outer surfaces are covered.
Connection between said coating of organic material 41, ceramic member inner liner 42, coating of organic material 43 and the shell 44 adopts vulcanization to combine closely.
Said ceramic member inner liner 42 is made up of the small-sized potsherd 3 of polylith, and potsherd 3 employing alumina contents are 98.0%～99.9% ceramic material, and this kind material hardness is big, wear-resistant and impact.
Said shell 44 material therefors are stainless steel.
The utility model is employed in the grinding chamber that cavity wall is provided with the ceramic member inner liner 42 and the composite lining material 4 of shell 44 combinations, and is simple in structure, shock-resistant; And the high purity aluminium oxide material that ceramic member inner liner 42 uses; Have performances such as wear-resisting, corrosion-resistant, can the comminuting matter in the mill chamber not polluted, can effectively guarantee the quality of converted products; Ceramic member inner liner 42 adopts the small-sized potsherd 3 of polylith to form, and can solve problems such as large-size ceramic liner difficult processing and easy be full of cracks.

Connection between said coating of organic material 41, ceramic member liner 42, coating of organic material 43 and the shell 44 adopts vulcanization to combine.
Said coating of organic material 41 and 43 used organic materials are epoxy resin.
Said coating of organic material 41 upwards extends below at two ends, and 42 liang of end surfaces of ceramic lining and shell 43 seam crossing outer surfaces are covered.
The thickness of said coating of organic material 43 can be 2mm, 2.5mm, 3mm or 4mm.
Said ceramic member liner 42 adopts alumina material, and its content can be 98%, 98.5%, 99.5%, 99.9% or 99.95%.
Said shell 44 can adopt stainless steel material to make.
