The Basic Working Principle Of Ball Mill

The ball mill is mainly composed of cylindrical barrel

, cover, bearings and big driving gear ring and etc.

1. Cylinder: mm in diameter which 150mm in for the steel ball -- or steel bar, called grinding medium, and its load quantity of effective volume for the entire cylinder of 25% -- 50%.

2. Cover: the cylinder cover, using the screws on both ends with a cylinder body ends flanges connection, with a hole in the middle of the housing, called the hollow shaft neck.

3. Bearing: hollow in the bearing, trunnion supporting cylinder body to turn.

4. Big gear circle: in barrel at a fixed.

Grinding process is introduced

Grinding operation is performed within the ball mill simplified, cylinder grinding interface with the rotation of the cylinder body was brought to a certain height, weight and whereabouts, medium due to install in the cylinder body ore are medium heavy wallop; On the other hand, because in the cylinder body grinding interface along the axis of revolution and the cylinder body rotation, and in between grinding interface cylinder body contact area and produce the extrusion and grinding of minerals, which strip force grinding ore.

The ball mill ball (grinding medium) when the cylinder rotate namely was taken up and rise to a certain height, because the gravity ball itself along certain track, at last fall. In the area of steel ball of the two force by: one is the rotation since the force was tangent direction; As a side and ball diameter with relative says the forces opposite force, the force may be caused by gravity and ball itself caused by the downward slide. These two forces, ball will constitute a pair for ball was, because couples exerting on the annular in cylinder and adjacent squeezing the middle, so couples exerting on the annular ball will vary in size between the ball with cylinder of friction, made in revolution axis movement within the region since last fall in the area fell, thrown on the cylinder body in the ore produce powerful impact, will ore broken. Can say, the grinding ore main cylinder body is influenced by grinding strip force, impact and the role of extrusion pressure by grinding.Belt conveyor : http://www.best-crushers.com/belt-conveyor.htmBall mills : http://www.ore-machine.com/ball-mill.htmlby: jocelyn
