Abstract
The utility model relates to a roller finishing machine used for grinding dry abrasive grit, wet abrasive grit, and suspended liquid state abrasive grit, which comprises a machine frame, a barrel body provided with an abrasive grit inlet and an abrasive grit outlet and fixedly connected with the machine frame, a grinding rotor positioned in the barrel body, and an electric motor used for driving the grinding rotor, wherein, the grinding rotor is a rotating shaft sheathed with axially arranged rotating disks, the outer circle of each rotating disk is provided with a U-shaped axial direction groove with a semicircle sectional plane, each axial direction groove is provided with a cylindrical roller in a loosening way, and the cylindrical roller is in rolling contact with the inner wall of the barrel body. The utility model has the advantages of high grinding efficiency, narrow grain size distribution of grinding product, no problems of difficult isolation between grinding medium and grinding material in a successive grinding process.
Description
The utility model relates to a kind of roller grinder that is used to grind dry grinding material, wet-milling material and suspension abrasive material, and is particularly a kind of with the roller grinder of cylindrical roller as abrasive media.
Existing medium grinder, the overwhelming majority adopts the spherical grinding medium.Mill ball is deposited in the grinding cylinder, and its freedom of motion is unrestricted.Make the mill ball motion by the stirring action of dispersion disk in the grinding cylinder or the rotation or the vibration of cylindrical shell self.Mill ball is at the volley because the difference of its direction of motion and speed produces shearing and effect of impact, thereby pulverizing is clipped in grinding charge material therebetween.Typical milling apparatus such as ball mill and sand mill.Since in process of lapping between the mill ball with mill ball and barrel between contact and be a contact, and the interaction force size between the mill ball has randomness, so grinding efficiency is low, the abrasive product particle diameter distributes also than broad.And, in the continuously grinding process abrasive media be difficult problem separating of grinding charge material.
The purpose of this utility model is the roller grinder that a kind of grinding efficiency height, abrasive product particle diameter narrow distribution is provided, can solves abrasive media and grinding charge material separation problem in the continuously grinding process.
For achieving the above object, the utility model adopts following technical proposals: the utility model is the same with prior art to include frame, be fixedly connected on having cylindrical shell that abrasive material imports and exports, being placed in the grinding rotor in the cylindrical shell and the motor of driving grinding rotor of frame.It is characterized in that grinding rotor is the rotating disk that suit 1-40 axially-aligned in the rotating shaft, the axial groove of 4-500 cross section for semicircle or " U " shape arranged on each rotating disk cylindrical, cylindrical roller of loosening configuration in each axial groove, cylindrical roller rolls with cylinder inboard wall and contacts.This roller grinder with cylindrical roller as abrasive media.When rotating disk rotates with rotating shaft, cylindrical roller is because the inertia force effect is thrown toward cylinder inner surface, and roll along cylinder inboard wall with the frictional force effect of cylinder inboard wall, cylindrical roller rotation in the axial groove of rotating disk, thereby make abrasive media produce two kinds of pulverizations to the grinding charge material: the one, the pulverizing that rolls that cylindrical roller rolls and forms along cylinder inboard wall; The 2nd, the shearing between cylindrical roller time rotational and axial groove is pulverized.The orderly motion of cylindrical roller makes the grinding charge material be subjected to thick-and-thin active force in process of lapping, pulverizes the particle diameter narrow distribution of back finished product.Because cylindrical roller is the line contact with contacting of cylinder inboard wall, cylindrical roller contacts between line contact and face contact with the rotating disk axial groove, and its effective abrasive areas substantially exceeds existing medium grinder, has therefore improved grinding efficiency.This roller grinder also makes in the continuously grinding process separation problem of original more scabrous abrasive media and grinding charge material not exist.
Selection scheme best in the utility model is the rotating disk that is set with 2-10 axially-aligned in the rotating shaft, and 10-100 axial groove arranged on the annual rotating disk cylindrical.At the rotating disk two ends back-up ring that prevents the cylindrical roller axially-movable can be housed.The axial groove diameter can be than the big 0.05-0.3 millimeter of cylindrical roller diameter.The chuck that has import and export can be equipped with in the cylindrical shell outside, can lead to people's heating or cooling medium, thus the temperature of control grinding charge material, to satisfy the different process requirement.Grinding rotor can directly connect a variable-speed motor or connect motor by a variable transmission, thereby can change the grinding rotor rotating speed, regulate cylindrical roller to the radial pressure of cylinder inboard wall and the relative shear speed between cylindrical roller and axial groove, reach the finished product grain size of control grinding charge material.The material of cylindrical shell, rotating disk and cylindrical roller all adopts wear-resisting hard material, as engineering ceramics, carbide alloy or hardened steel.Certainly, general structure of the present utility model can be vertical structure or horizontal type structure.
The utility model compared with prior art, have following conspicuous advantage: the grinding efficiency of this roller grinder is higher, abrasive product particle diameter narrow distribution, the problem that does not exist the abrasive media difficulty to separate with the grinding charge material in the continuously grinding process.This roller grinder not only is applicable to and grinds dry grinding material and wet-milling material, also is applicable to grinding suspension shape abrasive material.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the profile at A-A place among Fig. 1.
An optimum implementation of the present utility model is: referring to Fig. 1 and Fig. 2, this roller grinder is vertical roller grinder.The abrasive material that has that it includes frame 15, be fixedly connected on frame 15 is imported and exported 3,13 cylindrical shell 5, is placed in the grinding rotor 6 in the cylindrical shell 5 and driven the motor 16 of grinding rotor 6.Grinding rotor 6 is rotating disks 7 that suit 2 axially-aligned in the rotating shaft 10, and it is semicircular axial groove 1 that 12 cross sections are arranged on each rotating disk 7 cylindrical, cylindrical roller 8 of loosening configuration in each axial groove 1.Axial groove 1 diameter is bigger 0.2 millimeter than cylindrical roller 8 diameters.The back-up ring 9 that prevents cylindrical roller 8 axially-movables is equipped with at rotating disk 7 two ends.Cylindrical shell 5 outsides are equipped with to have and are imported and exported 2,11 chuck 4.The material of cylindrical shell 5, rotating disk 7 and cylindrical roller 8 is hardened steel.Motor 16 is a variable-speed motor, and the output diameter of axle shaft coupling of motor 16 directly connects the rotating shaft 10 of grinding rotor 6, and rotating shaft 10 is supported to outstanding thumb structure, rotating shaft bottom suit rotating disk 7 and back-up ring 9 by 2 bearings 14.
