Bidirectional rotating ball mill grinding mill principle

way rotating ball mill grinder is an advanced technology portable Crusher, new energy-saving ultra-fine crushing equipment. This paper analyzes the crushing principle.
ordinary ball mill, ball first brought to a certain height by the rotation of the cylinder, then the ball out of the cylinder due to gravity and the falling down due to the falling ball during a certain kinetic energy leaving the material to be crushed . Clearly, the rotational speed of the grinding cylinder has a critical value, the centrifugal force is too high will cause excessive ball and rotate together with the cylinder, so that the ball is too small to rise high enough, which is not conducive to grinding balls of material, and this Since only the outer cylinder mill kind of rotation, to be pulverized material force than a single, simple, and a small force of strength, therefore low grinding efficiency, if pulverized coal, pulverized time often up to several tens of hours, the average particle size of the product is 10um or less difficult to achieve. The two-way rotary milling mill is meet these requirements. Internal

way rotating ball mill grinder is provided a stirring device, the rotational direction of the outer tube and the inner agitator running in the opposite direction. This is a common ball mill grinding and grinding ball mill Vertical Roller Mill grinding Field Field combine to make the same grinding cavity can produce a variety crush force field, so that movement of balls for a variety of directions, in the process of crushing, outer cylinder (built with angled baffles) driven ball over the cylinder rotates, blender drive balls for reverse movement, so that ball in the cylinder body movement disorganized, and increased ball velocity, increasing ball big impact on the cylinder wall, greatly improved the crushing effect. In addition, this device within the outer tube and a stirrer equipped with water cooling device to prevent the process of crushing heat, grinding process to ensure safety.
