Abstract

The utility model discloses a grinding plate of a raw material grinding mill, which is fixed onto a speed reducer. A grinding surface of the grinding plate is annular, a grinding roller is fixed onto the grinding surface of the grinding plate, the grinding surface of the grinding plate matches with the grinding roller, and a grinding gap is reserved between the grinding surface of the grinding plate and the grinding roller. The grinding plate is characterized in that gradient is arranged on the grinding surface from outside to inside. The grinding plate with the structure is high in abrasion resistance and hardness, raw materials are uniformly distributed in a grinding area during grinding assuredly, accordingly, safety and reliability of a grinding plate device are improved, simultaneously, materials are saved, and energy consumption is reduced.

Description

A kind of raw material mill mill

Technical field

The utility model relates to building materials, metallurgy, electric power and chemical field, in particular, relates to the device of a kind of cement raw material and other material grinding or the double grinding of oven dry.

Background technology

In the industrial processes production process, usually need carry out milled processed to raw material, in the Cement Production process, need be to the processing of milling of the raw material of cement, and the cement raw material mill is the requisite device of technology of milling, it has critical role in cement company.Because cement slurry is seen cement raw material off after being added the processing of milling in the mill continually more endlessly in the mill processes, so its each modular construction must be sturdy and durable, the degree of wear is high; Mill as one of raw material mill vitals; Because it be a direct abrasive action mechanism, need to require higher for its wearability, but the manufacture of cement manufacturer mill structure of using raw material to grind is cast-in-block plane mill at present; There are following two problems in it: 1) when operate as normal along with the rotation of mill; The influence that raw material receives centrifugal force disperses on mill, but owing to be the plane mill, and raw material skewness on this mill causes that the thickness of feed layer at each position differs on the mill; Cause motor load big easily, cause whole raw material mill to quit work; 2) the grinding track of grinding roller is vertical with mill, makes that the gap is less between grinding roller and the mill, under the situation of bed of material skewness, has strengthened the contact-making surface aggravation mill of grinding roller and mill and the wearing and tearing of grinding roller.

The utility model content

The technical problem that the utility model will solve is that realization is a kind of firm wear-resisting, can be evenly distributed in the mill of the raw material on the abradant surface.

To achieve these goals; The technical scheme that the utility model adopts is: a kind of raw material mill mill; This mill is fixed on the reductor and the abradant surface of mill is annular; Be fixed with grinding roller on the mill abradant surface, described mill abradant surface matches with grinding roller, it is characterized in that: there is the gradient in described abradant surface in extroversion.

The cross section of described mill abradant surface is the cambered surface that highly inwardly reduces gradually.

Described mill comprises the abrasive disk seat that is fixed on the reductor; Be fixed in the annular mill liner plate on the abrasive disk seat; Be fixed in the blocking material ring of mill liner plate outer ledge; And the pressing plate that is arranged at mill liner plate inside edge, described mill liner plate is an abradant surface, the mill center is provided with the taper cover plate that raises up.

Described blocking material ring inward flange stretches out in outward flange to the mill liner plate of mill liner plate.

There is the fixing gap of grinding between described grinding roller and the mill abradant surface.

Described grinding roller is the wheel the form of the foetus.

The advantage of the utility model is that this mill structure scuff resistance is high, and hardness is big, can guarantee that raw material is evenly distributed in abrasive areas in process of lapping, thereby has promoted the security reliability of mill device, has practiced thrift material simultaneously, has reduced energy consumption.

Description of drawings

Facing the content of the every width of cloth accompanying drawing expression of the utility model specification and the mark among the figure down briefly explains:

Fig. 1 is the mill structural representation;

Fig. 2 is a mill partial enlarged drawing shown in Figure 1;

Mark among the above-mentioned figure is: 1, blocking material ring; 2, abrasive disk seat; 3, mill liner plate; 4, pressing plate; 5, cover plate; 6, grinding roller; 7, reductor.

The specific embodiment

Can know that referring to Fig. 1,2 the raw material mill mainly comprises: mill, grinding roller 6 and reductor 7, wherein mill is made up of blocking material ring 1, abrasive disk seat 2, mill liner plate 3 and pressing plate 4; The abrasive disk seat 2 of mill is fixed in reductor 7 tops by high-strength bolt, drives whole mill rotation thereby drive abrasive disk seat 2 rotations by reductor 7, and abrasive disk seat 2 tops are mill liner plate 3; Mill liner plate 3 is the abrasive areas of this mill for annular, and mill liner plate 3 adopts the built-up welding mode to make and forms, thereby hardness is high; Scuff resistance is high, has reduced the maintenance frequency of raw material mill, effectively raises production capacity; Mill liner plate 3 outer ledges of annular are provided with blocking material ring 1, and blocking material ring 1 is by being bolted on the abrasive disk seat 2, and the outer ledge of mill liner plate 3 is stretched out in its inside edge; Because blocking material ring 1 is wide and highly low, thereby has effectively controlled thickness of feed layer, one circle is provided with pressing plate 4 along mill liner plate 3 inside edges; Grinding roller 6 is fixed in the mill top for the wheel the form of the foetus; Grinding roller 6 matches with mill and has fixing grinding gap, and is low high all around in the middle of the annular abrasion face of mill, in extroversion, has the gradient; Say so the more specifically cambered surface of cross section for highly inwardly reducing gradually of abradant surface; Grinding orbit-shaped in process of lapping between abradant surface and the grinding roller 6 at an angle rather than vertical, thereby the contact-making surface that has just effectively improved grinding roller 6 and mill abradant surface has reduced the wearing and tearing of parts, is provided with one at the center of mill and is provided with the taper cover plate 5 that raises up.

During operate as normal; The raw material mill hangs down the formation radiation through feed system feeding in mill around high in the middle of 5 one-tenth tapered structures of the cover plate above the mill, the center abradant surface of mill can evenly sent into and be distributed to this structure raw material under centrifugal action; Such structure also guarantees the no backup in the blanking centre position; Thereby mill center uniform distribution, and what adopt is the arc mill, and it forms a fixing grinding gap with wheel fetalism grinding roller 6 and forms abrasive areas; The bed of material can grind and the lapping degree height after getting into abrasive areas uniformly fully, finally accomplishes the overall process of former abrasive lapping.This mill diameter is than the little 500mm of conventional mill simultaneously, and its rotating speed can increase 1-2rpm, thereby economical with materials has reduced energy consumption.
