The front end face and the rear end face of the ball grinding barrel body 1 are provided with a feed inlet 5 and a discharge outlet 6, and lining plates are arranged inside the ball grinding barrel body and are used for placing grinding balls. Which breaks up the material by rotation. In this embodiment, the ball mill is a horizontal ball mill, and therefore the ball mill cylinder 1 is axially and horizontally disposed in a normal crushing state.

Since the ball mill barrel 1 needs to be rotated, a slewing bearing structure is required, and in this scheme the mounting mechanism 3 is used for bearing the rotation of the ball mill barrel 1 and comprises a pair of annular guide grooves 7 and a mounting frame 8. The annular guide grooves 7 are respectively and fixedly arranged at the front section and the rear section of the ball grinding cylinder body 1. The mounting frame 8 is in the form of a pair of hexagonal annular frames 17 and four connecting beams 16 connecting a pair of the annular frames 17. As can be seen from the attached drawings, the annular frame 17 is of a double-layer structure and is divided into a left half part and a right half part which are detachable, the guide wheels 10 are arranged on the inner side of the

annular frame

17, and 3 guide wheels 10 are respectively arranged on each half part. Half left side is connected through connecting piece 18 with half right side, and connecting piece 18 can adjust the elasticity degree of annular frame 17, consequently sets up to lead screw and nut complex structure, and the lead screw is half left side and half right side of spiro union annular frame 17 respectively for annular frame 17 can stably embrace ball mill barrel 1. The connecting beam 16 connects a pair of annular frames 17 in front and rear, and a horizontal rotary shaft 9 is provided at the rear section of the connecting beam 16 to extend outward in the left and right direction. The ball mill cylinder 1 is axially pivotally arranged in the mounting frame 8 by means of a sliding connection of the guide wheel 10 with the annular guide groove 7.

The power component 2 is used for driving the ball mill barrel 1 to rotate, because the ball mill barrel 1 needs to be inclined to drive powder and grinding balls to gather and discharge in the scheme, the power component 2 needs to be set to be in a form convenient to combine, particularly, the power component comprises an outer gear ring 13 arranged in the middle of the ball mill barrel 1, a gear 14 arranged right below the ball mill barrel 1 and a speed reduction motor 15 driving the gear 14 to rotate, and when the ball mill barrel 1 is axially horizontal, a circle center connecting line of the outer gear ring 13 and the gear 14 is perpendicular to the horizontal plane. In the device, the front section of the ball mill cylinder body 1 needs to be lifted and inclined towards the discharge hole 6, so the rotating shaft 9 is arranged behind the outer gear ring 13. During the lifting adjustment, as shown in the drawing, the external gear ring 13 and the gear 14 can be separated and can be meshed.

The lifting mechanism 4 can turn over the mounting mechanism 3, so that the ball mill barrel 1 can be driven to incline, and comprises a pair of shaft seats 11 for mounting the rotating shaft 9 and a pair of lifting oil cylinders 12 arranged at the front section of the ball mill barrel 1. Wherein, the shaft seat 11 provides a slewing bearing for the rotation of the rotating shaft 9, and the lifting oil cylinder 12 is used for lifting the front section of the ball milling barrel body 1.
