subject: Fortune: Mineral Processing Operations In The Mill Working Principle And Function - Dressing, Ball [print this page] Ore mining to go through such a process: start with jaw of iron ore mining Crusher Preliminary crushing, to a reasonable fineness in broken through after Hoist , Even into the feeder Ball Mill By the ball on the ore crushing, grinding. Developed through the mill ore fines into the classification process. Spiral Grader The proportion of solid particles with different speed in different liquids are often the principle of classification of the ore mixture. Let the following Zhengzhou Xinhai Machinery Manufacture company's technical staff to us about the processing operations in the mill working principle and function.
Grinding operation is carried out in the mill cylinder body, cylinder body with grinding media. Grinding media as the rotating cylinder was taken to a certain height, weight and because the whereabouts of the medium. Then mounted in the cylinder body of ore on the role of impact by the media; the other hand, as grinding medium in the cylinder body along the cylinder axis of revolution and rotation, in between grinding media and this resulted in the contact area with the cylinder extrusion and grinding of the ore stripping force, which will grind ore.
Ball machine because Ruiguang between ball and cylinder friction, when the cylinder rotates, steel balls are taken from and to rise to a certain height, as Ball's own gravity, and finally along a certain Track Road whereabouts. In the region (Ball was put on) the ball by the role of two forces: one for the cylinder from the tangential direction of rotation of the force applied on the ball; the other corresponding to the diameter with the ball with the side force opposite force, the force generation is due to its own dead weight ball caused by sliding downwards.
Therefore, these two forces, for any ball will form a pair of force couple. As the ball is being squeezed and the cylinder and the adjacent ball in the middle, so Couple will exist between the size of steel balls ranging from friction, and thus each layer with the cylinder axis ball will turn for the public sports (of course, not all levels of ball speed and cylinder are synchronized, while levels of public revolution speed ball not the same). In the region since last fall into the falling ball, which in regions of the cylinder body of ore crushing impact that a strong role. As the ball when the whereabouts of an impact, and hence in the region have an extremely strong ball movement without order.
Including: (1) of the strong line side ball rolling; (2) points along the line of fast moving ball; (3) of line with the ball mill shell following the rapid movement; (4 ) between the conflicting layers of steel balls. Visible region that is grinding the role of the strongest areas. Most of the coarse mineral particles are ground here.
Can see from the above, the main ore body in the tube mill is subject to impact, grinding force and the squeeze pressure stripping the role of being grated.
