Abstract

One kind of superfine high speed ball mill operating on rolling bearing principle is disclosed. It has one static outer ring and one radially sliding inner ring with annular ball track each. The special steel ball with handle is used as the rolling body and its handle may be inserted into a holder capable of rotating freely and with rectangular chute. The superfine high speed ball mill is simple, reliable, convenient in maintenance, high in electric energy utilization rate, high material crushing speed and capacity of preparing micron level or even nanometer level material.

Description

The bearing mill

Technical field the present invention relates to a kind of efficient ultra-fine ball mill, and crushing metal ore deposit and nonmetallic ore are the desirable regeneration products of all kinds of cement plants ball mill to more than the micron order fast.

The current market supply of background technology no matter be vertical or horizontal ball mill, its disadvantage is heavy, complicated, the electric energy effective rate of utilization is low, and wearing and tearing are big, noise is big, labor strength height, not environmental protection.

Summary of the invention the present invention utilizes the rolling bearing principle, abradant surface is by interior, the ring raceway of outer ring is formed jointly, this ring raceway section shape can be straight line, also can be the curve of arbitrary shape, adapt with the raceway shape, rolling element is the revolving body along the rotation of self axis of respective shapes, this rolling element has a cylindrical handle, pommel has bearing, be inserted with in the rectangle chute retainer free to rotate, for having eliminated the stopping time rotation error, the inner ring that can radially slide has the spring pretension on (or outer ring), powerful centrifugal force and part spring power that the extruding force during grinding mainly comes spinning to produce.

The description of drawings material is entered by time material mouthful 1, power drives belt pulley 2, main shaft 3, key 4 through exterior motor and makes flower stand 9 rotations, and rolling element 8 is compressed in rotation and grinding material in the raceway that outer ring 7 and rolling element 8 profiles adapt under the centrifugal force acting in conjunction of the preloading spring 10 and the inner ring 6 that can radially slide.Handle drive by rolling element 8 simultaneously has 11 rotations of rectangle chute retainer free to rotate, and material is discharged from the discharging opening of frame 5 through successively grinding the back.Fig. 1 is a front view, and Fig. 2 is a vertical view.

Above-mentioned each parts of the specific embodiment are successively loaded onto main shaft successively from the bottom to top and are got final product.

Claims (4)

1, its basic principle is the rolling bearing principle.The abradant surface of this ball mill is made of jointly the Internal and external cycle that has annular steel ball rolling channel face, and a circle maintains static, and another circle can radially slide, and its power of radially sliding comes from centrifugal force or the spring force that rotation produces, and can vertical installation also can horizontally install.

2, rolling element---steel ball is a band handle steel ball, and steel ball is the revolving body of arbitrary resemblance.Be that horizontal section should be standard round, longitudinal profile be the axis symmetry face body or curved body directly, handle is cylindrical.

3, retainer is the empty rotary disk that is enclosed within band rectangle chute free to rotate on the main shaft.

4, the spring of pretension active force on movable inner ring (or outer ring) arranged.
