For to being played castering action by the material of ball milling and steel ball, the inwall of described cylinder is provided with rib, and described rib is along the axial distribution of cylinder.Rib can adopt modes such as welding or screw riveted joint to fix, and is suitable evenly to be distributed as.
In order to increase steel ball and by the probability of mutual collision, friction, extruding and shearing between the milling material, described stirring tool is one group of stirring rod, described stirring rod is staggered on rotating shaft; The angle of described stirring rod and rotating shaft is 15 °～90 °.
The cross section of described rib is a rectangle or trapezoidal, and perhaps the bottom is a rectangle, and the top is an arc.
The quantity of described rib is 3～12.
Beneficial effect: horizontal high-speed compound ball mill of the present utility model compared with prior art, has the following advantages:
1, by the reverse rotation device is set, can eliminate the centrifugal force of steel ball in cylinder, overcome the restriction of ball mill critical speed, can greatly improve the operating efficiency of ball mill;
2, along with the raising of drum's speed of rotation, also be further enhanced by the quality of milling material, good by the granularity uniformity of milling material;
3, the raising of drum's speed of rotation can be shortened the ball milling time, and effectively saves energy reduces cost of labor;
4, the utility model only is that the reverse rotation device is installed in the cylinder of common horizontal ball mill, thus simple in structure, be easy to realize, help enlarging and produce and promote the use of.
