Abstract
The utility model disclose a grinding disk and grinding roller structure of a vertical mill, which comprises a grinding disk, a grinding roller and a grinding disk lining plate surface, wherein the front part of the grinding disk lining plate surface is a plane of which the length is 150-250mm; the rear part of the grinding disk lining plate surface is a slope of which the length is 500-400mm; the front-part panel of the grinding disk lining plate surface is parallel to the plane of the grinding disk; and a free gap between the grinding disk lining plate surface and the grinding roller is 8-12mm. According to the grinding disk and grinding roller structure of a vertical mill, limit contact between the grinding disk lining plate surface and the grinding roller is changed into linear contact from point contact when the grinding disk lining plate and the grinding roller work, thereby greatly enlarging the area of the contact surface, bringing the convenience for stably forming a material layer, improving the operation stability of the vertical mill, reducing the vibration of the vertical mill, and improving the grinding quality and the yield of the vertical mill.
Description
Technical field
The utility model belongs to the Vertical Mill technical field, relates in particular to a kind of mill and grinding roller structure of Vertical Mill.
Background technology
Vertical Mill mainly is made up of transmission device, hydraulic means, powder concentrator and mill, grinding roller etc., and the grinding roller of rolling is relatively partly made in groundwork for mill and on mill.Material in the feeding Vertical Mill is under action of centrifugal force; On mill, form annular material bed; Material is embedded between mill and the grinding roller when mill and grinding roller roll relatively; The bulk materials effect of at first being squeezed is pulverized, and the grinding roller applied pressure passes on time one-level bulk materials subsequently, and so raw meal particle size reduces step by step.Under the roll extrusion effect, pulverized big and small granule materials is tightly packed in very little space, transmits pressure thereupon each other and slide relatively to produce shearing force, so just further with the fine grinding of smaller particles thing.Mill liner plate and grinding roller roller shell combine angle determined grinding machine fineness of grind and operation steadily whether, be the deciding factor that improves Vertical Mill Grinding Quality and output.
Mill liner plate angle of the prior art and size; When Vertical Mill work is in limiting condition, form point and contact, cause local pressure to concentrate, make grinding roller produce high vibration with the grinding roller roller shell; The head working face large tracts of land that causes the grinding roller roller shell drops; Shorten the life cycle of grinding roller roller shell greatly, increased equipment failure rate and maintenance cost, and caused the damage of a series of miscellaneous parts.
The utility model content
The purpose of the utility model is to provide a kind of mill and grinding roller structure that reduces the Vertical Mill vibration, increases the Vertical Mill of Vertical Mill smoothness of operation, raising grinding machine Grinding Quality and unit-hour output.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:
A kind of mill of Vertical Mill and grinding roller structure; Comprise grinding roller, mill and mill liner plate face; Portion is the plane of length 150～250mm in face of the said mill liner plate; The rear portion is the inclined-plane of length 500～400mm, and the anterior plane parallel of said mill liner plate face is in the plane of said mill, and the free clearance between said mill liner plate face and the said grinding roller is 8～12mm.
The preceding facial planes length of said mill liner plate face is 200mm, and the rear ramped surface length of said mill liner plate face is 450mm.
Free clearance between said mill liner plate face and the said grinding roller is 8mm.
The mill of the Vertical Mill that the utility model provides and grinding roller structure; The limit contacted by a contact and becomes the line contact when mill liner plate was worked with grinding roller; Increase the contact-making surface area greatly, helped the stable formation of the bed of material, improved the smoothness of operation of Vertical Mill; Reduce the vibration of Vertical Mill, improved the Grinding Quality and the output of Vertical Mill.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the working condition sketch map of the utility model.
Among the figure, 1-grinding roller, 2-mill, 3-mill liner plate.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing thereof the present invention is described further.
As depicted in figs. 1 and 2, a kind of mill of Vertical Mill and grinding roller structure comprise grinding roller 1, mill 2 and mill liner plate face 3.The front portion of mill liner plate face 3 is the plane of length 200mm, and the rear portion is the inclined-plane of length 450mm, and the anterior plane parallel of mill liner plate face 3 is in the plane of mill 2, and the free clearance between mill liner plate face 3 and the said grinding roller 1 is 8mm.
The inclined-plane of the whole 600mm length of former mill liner plate face two parts in plane and inclined-plane have been become.The front portion of mill liner plate face 3 is changed into by intrinsic inclined-plane after the plane, can the free clearance between mill liner plate face 3 and the grinding roller 1 be shortened to 8mm by intrinsic 16～20mm.Like this, the output of Vertical Mill is brought up to 52～55 tons/hour by intrinsic 45 tons/hour, and the specific area of product is by 420m
2/ kg brings up to 450 m
2More than/the kg.
Mill liner plate and grinding roller roller shell are the rotation working parts of grinding machine, are the movable bodies of a pair of relative rolling, also are the root places that grinding machine produces high vibration.Mill liner plate face has determined Vertical Mill fineness of grind and traveling comfort with the angle that combines of grinding roller roller shell, is the key factor that influences grinding machine quality and output.
The mill of the Vertical Mill that the utility model provides and grinding roller structure; Grinding roller contacts (being the zero clearance contact) and becomes the line contact on the present 50mm length by intrinsic some contact with the limit of mill liner plate; Increased the contact-making surface area between grinding roller and the mill liner plate greatly, helped the stable formation of the bed of material, especially when operating troubles such as the instantaneous fracture of Vertical Mill take place; Owing to increased the limit contact area between grinding roller and the mill liner plate; Instantaneous contact pressure reduces greatly, more can embody the protective effect to grinding machine, has well improved the smoothness of operation of grinding machine.
Above-described only is the preferred embodiment of the utility model, does not limit to the utility model.Should be understood that for the person of ordinary skill of the art, under the teachings that the utility model provided, can also make other equivalent modifications and improvement, all can realize the purpose of the utility model, all should be regarded as the protection domain of the utility model.
