Abstract
The present invention relates to a pulverizing method, in particular it is used for cement raw material pulverizing mill, cement clinker pulverizing mill and pulverizing slag, belonging to the field of industrial pulverizing technology. Said pulverizing method is mainly characterized by that it includes a grinding roll, said grinding roll is axially passed through a drum body, said grinding roll and drum body are eccentrically arranged. Said invention also provides its working principle and concrete steps for pulverizing cement raw material cement clinker and slag.
Description
Technical field
The present invention relates to a kind of grinding method, be used for the novel method of cement slurry grinding, the whole grinding of cement and grinding slag etc. specifically, belong to industrial grinding technology field.
Background technology
At present, what known cement grinding and slag milling adopted is ball grinding method, utilization be collision, tribology principle, the steel ball that utilizes the various granularities in rotary barrel and material collision, friction and reach the purpose of grinding material, but this kind grinding method exists noise pollution to weigh, temperature rise, the time that grinds is long, and efficient is low, and equipment is huge, power consumption is big, takes up an area of problems such as many.Developing a kind of novel method at the existing problem of existing technologies is very necessary to overcome the problems referred to above.
Summary of the invention
In view of above-mentioned existing in prior technology problem, the present invention adopts a kind of different grinding method, and it is heavy that this grinding method has not only overcome the noise pollution of ball milling principle, temperature rise, efficient is low, and equipment is huge, the shortcoming that power consumption is big, occupation of land is many, and the grinding quality is improved.
A kind of eccentric internal-cutting type powder griding method of the present invention; Its structure is that grinding roller axially passes cylindrical shell, and grinding roller and cylindrical shell arranged off-centre, cylindrical shell is with certain speed rotation during work, the passive rotation of grinding roller, the material that enters the cylindrical shell from feeding end during grinding forms the annulation bed of material under action of centrifugal force, apply the needed pressure F of grinding material at the two ends of grinding roller, form the relative motion between cylindrical shell and grinding roller.
The dimension scale of the internal diameter of cylindrical shell of the present invention and the external diameter of grinding roller is 2～2.5: 1.
Cylindrical shell of the present invention is an active rotation, the material motive power that bed forms is provided, and energy is provided when grinding; Grinding roller is passive rotation, does work to material by apply adjustable pressure F at its two ends.
System pressure F of the present invention is 20～30MPa.
The ring of cylindrical shell of the present invention week inner surface and the ring week outer surface of grinding roller is all inlayed or the build-up wear-resistant material to form wearing layer.
The invention has the beneficial effects as follows: grind material energy-saving and environmental protection such as cement, slag, grinding quality height is compared with ball milling method, takes up an area of minimizing 50%, energy consumption reduction by 50%.
Description of drawings
The present invention has two accompanying drawings, wherein:
Fig. 1 is a kind of fundamental diagram of eccentric internal-cutting type powder griding method.
Fig. 2 is the side direction view of Fig. 1.
Among the figure: 1, cylindrical shell, 2, the cylindrical shell wearing layer, 3, grinding roller, 4, the grinding roller wearing layer, 5, the annulation bed of material, the power that F, grinding roller two ends apply.
The specific embodiment
In the embodiment shown in fig. 1, cylindrical shell 1 is with certain speed rotation, and material enters cylindrical shell 1 from feeding end and forms the annulation bed of material 5, applies power F at grinding roller 3 two ends, the annulation bed of material 5 between cylindrical shell wearing layer 2 and the grinding roller wearing layer 4 by grinding after, export from discharge end.
The technical solution adopted for the present invention to solve the technical problems is: it is to utilize the eccentric inscribe grinding material principle of cylindrical shell and grinding roller to carry out grinding.Grinding roller axially passes cylindrical shell, the two arranged off-centre, the grinding surface of cylindrical shell and grinding roller inlay or the build-up wear-resistant material to form wearing layer, make cylindrical shell with certain rotating speed rotation during grinding, the material that enters the cylindrical shell from feeding end forms annular material bed under action of centrifugal force, apply the needed power of grinding material at the two ends of grinding roller, so just form the relative motion that cylindrical shell and grinding roller are asked, and exert pressure work done by the material of grinding roller in cylindrical shell and reach the purpose of grinding material, material behind the grinding is Powdered, exports from discharge end.
For coordination, the unification that reaches mill efficiency and effect, the optimal proportion of the internal diameter of cylindrical shell 1 and grinding roller 3 external diameters is 2～2.5: 1;
This grinding method system pressure belongs to the mesohigh category generally at 20～30MPa, and sealing is reliable, and is easy to maintenance;
This grinding method has automatic unloading protecting function, meets with an accidet state and when causing system pressure and load to exceed setting safety value, grinding system unloading is automatically protected, to avoid damaging critical component when grinding.
