Abstract
The utility model discloses a kind of crushing auxiliary of raymond mill, comprise bull ring and grinding roller, in the longitudinal section of described bull ring, the wall profile line of inner wall surface thereof is the camber line of evagination, and in the longitudinal section of described grinding roller, the lateral profiles line of its outside portion is the camber line of evagination.Described wall profile curvature of a curve is less than lateral profiles curvature of a curve.This crushing auxiliary products obtained therefrom granularity is comparatively thin, and be applicable to the production of super fine, crush efficiency is high, can improve output.
Description
Technical field
The utility model relates to the crushing auxiliary of raymond mill.
Background technology
Raymond mill is nonmetallic mineral processed and applied one of equipment the most widely, the basic structure of existing raymond mill is as follows: comprise support, the end face of support is connected with cylindrical shell, support is built with bull ring, support is rotatably connected to the main shaft stretched in cylindrical shell, main shaft is connected with plum blossom frame, hinge dress many covers grinding roller assembly on plum blossom frame, described grinding roller assembly comprises the grinding roller that hinge is contained in the shaft of grinding roller on plum blossom frame and is contained on shaft of grinding roller, grader is equipped with at the top of cylindrical shell, and the grading rotor of grader is positioned at cylinder lumen top.
Mainly there is following defect in the existing raymond mill of said structure: mostly crushing auxiliary (being made up of grinding roller and the bull ring) profile of raymond mill is the face of cylinder or taper seat, the main centrifugal force attrition crushing material produced by grinding roller revolution, its powder particles produced is comparatively large, and the shortcoming being not suitable for producing super fine is also more and more obvious.
Summary of the invention
The technical problems to be solved in the utility model is for above-mentioned defect, provides a kind of crushing auxiliary of raymond mill, to reach the less powder of acquisition, improves the object of crush efficiency.
For solving the problems of the technologies described above, the utility model provides a kind of crushing auxiliary of raymond mill of following structure, comprise bull ring and grinding roller, its design feature is: in the longitudinal section of described bull ring, the wall profile line of inner wall surface thereof is the camber line of evagination, and in the longitudinal section of described grinding roller, the lateral profiles line of its outside portion is the camber line of evagination.
Described wall profile curvature of a curve is designed to be less than lateral profiles curvature of a curve; One is to make material more easily enter between crushing auxiliary, and two is to increase distance of milling, to obtain better milling efficiency.
In each point on described wall profile line, apart from bull ring axial line farthest, the two-end-point of wall profile line is equal and nearest apart from bull ring axial line apart from the distance of bull ring axial line for the mid point of wall profile line; In each point on described lateral profiles line, apart from grinding roller axial line farthest, the two-end-point of lateral profiles line is equal and nearest apart from grinding roller axial line apart from the distance of grinding roller axial line for the mid point of lateral profiles line.
The crushing auxiliary of the raymond mill of said structure, because in the longitudinal section of bull ring, the wall profile line of inner wall surface thereof is the camber line of evagination, the camber line of this evagination rotates can go out ball annuli arrangement by envelope around bull ring axis, therefore the internal face of bull ring is ball face, and the lateral profiles line of its outside portion is the camber line of evagination in the longitudinal section of described grinding roller, the surface of revolution of grinding roller is equally also made to be ball face.There is the bull ring of ball annuli arrangement and the crushing auxiliary of grinding roller formation, not only be squeezed when material can be made to be broken power, also can be subject to the grinding forces produced because each point linear velocity on ball face is different, the granularity of product can be made greatly to reduce, the fineness of product is highly improved, is therefore applicable to super fine and produces.Above-mentioned crushing auxiliary has ball annuli arrangement because of it, and the contact area of bull ring and grinding roller increases thus increases pulverizing area, can improve crush efficiency and increase yield.
In sum, the utility model has the advantage of: products obtained therefrom granularity is comparatively thin, and be applicable to the production of super fine, crush efficiency is high, can improve output.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is the structural representation of raymond mill;
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Detailed description of the invention
As shown in Figure 1, existing raymond mill comprises support 1, the end face of support 1 is connected with cylindrical shell 2, support 1 is built with bull ring 3, support 1 is rotatably connected to the main shaft 4 stretched in cylindrical shell 2, main shaft 4 is driven by mair motor 13, main shaft 4 is connected with plum blossom frame 5, plum blossom frame 5 top is hinged with many cover grinding roller assemblies, and described grinding roller assembly comprises the grinding roller 7 that hinge is contained in the shaft of grinding roller 6 on plum blossom frame 5 and is contained on shaft of grinding roller 6; Be connected with multiple perching knife 12 for scooping up material bottom plum blossom frame 5, the quantity of perching knife 12 is identical with the quantity of described grinding roller assembly.Support 1 is provided with the fresh air inlet 14 of air intake in machine, and cylindrical shell 2 is provided with feed hopper 15, feed hopper 15 is equipped with and closes air-valve 16.The top of cylindrical shell 2 is provided with grader 11, and the grading rotor 8 of grader 11 is positioned at cylindrical shell 2 inner cavity top.Described bull ring 3 and grinding roller 7 form crushing auxiliary.
The utility model is the improvement that the crushing auxiliary formed for bull ring 3 and grinding roller 7 is made, as depicted in figs. 1 and 2, in the longitudinal section of described bull ring 3, the wall profile line 9 of inner wall surface thereof is the camber line of evagination, in each point on wall profile line 9, the mid point of wall profile line 9 apart from bull ring 3 axial line farthest, the two-end-point of wall profile line 9 is equal apart from the distance of bull ring 3 axial line, and the two-end-point of wall profile line 9 is nearest apart from bull ring 3 axial line.Wall profile line 9 rotates can go out a ball face by envelope around the axial line of bull ring 3, and that is the internal face of bull ring 3 is ball face.In the longitudinal section of described grinding roller 7, the lateral profiles line 10 of its outside portion is the camber line of evagination, in each point on described lateral profiles line 10, the mid point of lateral profiles line 10 apart from grinding roller 7 axial line farthest, the two-end-point of lateral profiles line 10 is equal apart from the distance of grinding roller 7 axial line, and the two-end-point of lateral profiles line 10 is nearest apart from grinding roller 7 axial line.Equally, lateral profiles line 10 also can go out a ball face by envelope around the axial line rotation of grinding roller 7, and therefore the surface of revolution of grinding roller 7 is also ball face.The curvature of above-mentioned wall profile line 9 is less than the curvature of lateral profiles line 10.The longitudinal section of above-mentioned bull ring 3 and the longitudinal section of grinding roller 7 refer to along the orthographic projection view after the axial line cutting of bull ring 3 and grinding roller 7.Outer in the camber line of above-mentioned evagination is relatively respective axial line, and the direction of abaxial line is outward, in the direction of axial line is.
