Abstract
The invention discloses a vertical mill. The vertical mill comprises an abrasive disk, grinding roller frames, grinding rollers and grinding roller shafts. The grinding roller frames are installed on transverse shafts. The grinding rollers are installed on the grinding roller frames through the grinding roller shafts. The angle of 5 degrees to 30 degrees is formed between the axes of the grinding rollers and the connecting lines of the centers of the grinding rollers and the center of the abrasive disk. Due to the fact that the angle of 5 degrees to 30 degrees is formed between the axes of the grinding rollers and the connecting lines of the centers of the grinding rollers and the center of the abrasive disk, friction force in the direction of the edge of the abrasive disk is generated while the grinding rollers grind materials, and the materials slide towards the edge of the abrasive disk in an acceleration manner. The materials cannot be ground into cakes through the double functions of grinding and friction force, and the powder grinding efficiency is improved.
Description
Technical field the present invention relates to extrusion type grinding machine, is specifically related to a kind of Vertical Mill.
The existing extrusion type grinding machine of background technology, shaft of grinding roller its direction of motion vertical, the evolute of grinding roller is overlapped with its direction of motion, and only have extruding to material, material is not easily pulverized, and on the contrary partial material is pressed into pie, and therefore mill efficiency is low.
Summary of the invention, in order to overcome defect and the weak point of prior art, the invention provides a kind of Vertical Mill.
Technical scheme of the present invention is:
A kind of Vertical Mill, comprise mill, grinding roller frame, grinding roller, shaft of grinding roller, transverse axis is arranged on grinding roller frame, and transverse axis is connected with shaft of grinding roller, and shaft of grinding roller is equipped with grinding roller, and grinding roller axis and grinding roller central point become the angle of 5 °-30 ° with the mill line of centres.
Described grinding roller axis and grinding roller central point become the angle of 5 ° with the mill line of centres.
Described grinding roller axis and grinding roller central point become the angle of 30 ° with the mill line of centres.
Described grinding roller axis and grinding roller central point become the angle of 10 ° with the mill line of centres.
Advantage of the present invention: because grinding roller axis and grinding roller central point to become the angle of 5 °-30 ° with the mill line of centres, the frictional force to mill edge is produced while grinding roller rolls material, accelerate material to mill boundary slip, material is rolling under the double action with frictional force, can not be pressed into cake, mill efficiency improves.
Description of drawings 1 is grinding roller frame inclination plan structure clockwise schematic diagram;
1, grinding roller; 2, shaft of grinding roller; 3, the grinding roller direction of motion; 4, transverse axis; 5, bearing; 6, mill; The direction of F, frictional force; 7, grinding roller frame.
A kind of Vertical Mill of detailed description of the invention, comprises mill 6, grinding roller frame 7, grinding roller 1, shaft of grinding roller 2, transverse axis 4 is arranged on grinding roller frame 7, transverse axis 4 is connected with shaft of grinding roller 2, shaft of grinding roller 2 is equipped with grinding roller 1, and grinding roller axis and grinding roller central point become the angle of 5 °-30 ° with the mill line of centres.
As shown in Figure 1, during work, rotated by transmission device band movable grinding disc 6, grinding roller 1 presses to mill 6 under external force, grinding roller 1 encloses shaft of grinding roller 2 rotation under the drive of mill 6, and material falls into mill 6 central authorities, because grinding roller axis and grinding roller central point to become the angle of 10 ° with the mill line of centres; Produce the frictional force to mill edge while grinding roller 1 pair of material rolls, accelerate material to mill boundary slip, material, rolling under the double action with frictional force, can not be pressed into cake, and mill efficiency improves.
