Analysis of the Separating Plate of Ball Mill

There are ladder liner or corrugated liner , built with different specifications of steel balls in the ball mill warehouse . Liner has a high impact fatigue durability, resistance to impact certain intensity ; has a lower wear rate during use of shape and not broken. This paper describes the principles of hierarchical classification mill liner .

The mill axis , in order to make the ball mill by grinding the end of the small segment from a hit , in order to process the material is adapted to the particle size , often using classification liner.

Grading mill liner in an axial cut surface slope , the tail end in the mill , grinding toward the low end . Ball liner is graded on a slope , gravity in the axial section which can be decomposed into two components , one of which is perpendicular to the slope bevel support , and the second is a lateral force parallel to the slope and its base point . Under the force of the ball with the cylinder for the partial circumferential standard operating , but when the ball enters the falling point of the liner in the classification effect , the ball will be in the form of a helix running direction of the grinding head . Thus, all graded liner contact grinding balls have flocked direction , subject to friction and wear in the space between the ball so that the ball mill to form a stacked face head tilted slightly lower Takao . As the big ball inertia than small ball , so the ball is more conducive to the accumulation of large occupies a point you want to occupy a small ball gave way to the big ball , enabling the ball descending arrangement .

In addition , the separation active role in making the small ball mill to run the ball from the big tail . Because the falling process, the cross-sectional area is proportional to the wind action with the ball , the ball is inversely proportional to the inertia force . The cross-sectional area is proportional to the square of the ball diameter ; inertial force is proportional to the quality of the ball , that is proportional to the cube and sphere diameter . Therefore , the impact with the ball diameter is inversely proportional to the wind , the greater the degree of force that the smaller the diameter of the ball end mill running .
