Abstract
The utility model discloses a vertical mill grinding structure. The structure comprises a grinding disc and a grinding roller, wherein a grinding disc lining plate is arranged on the grinding disc; grinding gaps are formed between the grinding roller and the grinding disc lining plate; the grinding gap positioned on the inner side of the vertical mill is larger than the grinding gap positioned on the outer side of the vertical mill. Through the vertical mill grinding structure provided by the utility model, materials can be ground efficiently and adequately; when a grinding machine is used for grinding materials, the gap at the feeding end of the inner part of a roller surface is larger while the gap at the outer part of the roller surface is kept constant, and the pressure of the grinding roller and the shearing force effect generated through the relative motion between the grinding disc and the grinding roller can be fully utilized for improving efficiency and saving energy.
Description
Technical field
The utility model relates to the structure of grinding roller and mill in Vertical Mill.
Background technology
Vertical Mill is when carrying out former abrasive lapping, need grinding roller and mill to cooperatively interact, fully grind raw material, but use at present the grinding roller of Vertical Mill and mill structure can not make full use of structure space and the structural behaviour between it, and being subject to the shearing force effect that between the pressure of grinding roller and mill and grinding roller, relative motion produces can not make full use of simultaneously, and the energy consumption while reaching product requirement while causing producing is too much.
Utility model content
Technical problem to be solved in the utility model is to realize a kind of Vertical Mill abrasive structure of guaranteeing that material can high-efficient grinding.
To achieve these goals, the technical solution adopted in the utility model is: a kind of Vertical Mill abrasive structure, comprise mill and grinding roller, described mill is provided with lining board for grinding discs, between described grinding roller and lining board for grinding discs, have grinding gap, the grinding gap that is positioned at Vertical Mill inner side is greater than the grinding gap in outside.
Described grinding roller is tyre type grinding roller, and its abradant surface cross section is arc, and described lining board for grinding discs cross section is the arc matching with tyre type grinding roller.
The outer of described lining board for grinding discs is provided with and is fixed on annular blocking material ring on mill.
Described grinding roller tilts fixing.
By the Vertical Mill abrasive structure of this patent, can carry out efficiently, fully material grinding, when grinding machine grinding material, roller flesh side portion's feeding splaying is large, the outside constant clearance of roller skin, can make full use of the shearing force effect that between the pressure of grinding roller and mill and grinding roller, relative motion produces, improve efficiency, saved the energy.
Accompanying drawing explanation
Below the content of every width accompanying drawing expression in the utility model description and the mark in figure are briefly described:
Fig. 1 is Vertical Mill abrasive structure schematic diagram;
Mark in above-mentioned figure is: 1, blocking material ring; 2, lining board for grinding discs; 3, mill; 4, grinding roller.
The specific embodiment
Known referring to Fig. 1, Vertical Mill abrasive structure mill 3 and grinding roller 4, wherein grinding roller 4 is tyre type grinding roller, and skin is provided with roller skin, and its abradant surface cross section is arc; Mill 3 is provided with lining board for grinding discs 2, and lining board for grinding discs 2 cross sections are the arc matching with tyre type grinding roller 4, and has grinding gap between grinding roller 4 and lining board for grinding discs 2, and the grinding gap that is positioned at Vertical Mill inner side is greater than the grinding gap in outside.Can carry out abundant high-efficient grinding to grinding material like this, the multiple grinding between roller skin and lining board for grinding discs 2 is portion in grinding roller mainly, and rubbing is mainly in grinding roller 4 outsides, thereby reach, reduces the power consumption effect of producing product.
In order further to improve grinding effect, grinding roller 4 tilts to be fixed in Vertical Mill, the outer of lining board for grinding discs 2 is provided with and is fixed on annular blocking material ring 1 on mill 3, this device is by the grinding roller 4 of tyre type, and between lining board for grinding discs 2, produce the multiple grinding near mill 3 centers, with near mill 3 outsides, have the rubbing of homogeneous space, after material is extruded, on mill 3 tracks, form material bed (material bed thickness is highly determined by mill blocking material ring 1), and expect that mutual extruding and friction between bed material particles cause peeling off of corner angle and edge, played the effect of further pulverizing, material is fully ground, and then enhance productivity in a process of lapping.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
