subject: Output Increasing And Energy Saving Principle Of The Mill [print this page] In terms of the copper ball, forging, rolling, casting can be the way to forge a ball. The iron ball can only be cast, because the ductility of steel is far from good compared with steel, neither can be forged nor rolled. As for a fixed material, the cost of forged steel ball is the highest, while cast steel ball has the lowest cost and high production efficiency of the rolling ball. Forged steel ball dense, density, excellent comprehensive mechanical properties (Table 5.3), regardless of rough grinding or fine grinding effect is very good (Table 5.3-2); rolling ball, followed by the heat-treated forged steel rolling ball. The overall mechanical performance in the end how all manufacturers to use different production processes must be based on objective and subjective conditions for a reasonable choice. Multifunctional grinding balls. The shape of the grinding balls is different from the Shougang Mining Company and the Malanzhuang iron ore proposed in 1983, "Malan baseball, it tends to be more reasonable.
Pairs of spherical segments. Such ball from the appearance point of view, they both ends of the form of spherical, cylindrical or trapezoidal in the middle. By cylindrical and trapezoidal, it is divided into A and B type ball. Dual-plane segment. Such ball from the appearance point of view, they are at both ends were flat, the shape of cylindrical or frustum of a cone. Its biggest drawback is that for a period of grinding, due to its extremely sharp edge, upon heat treatment, the hardness can be improved. Mill operation, the edge of each cylinder is cut on the mill liner inter-chopping. The type of ball mill liner damage is great, and exacerbated by the consumption of grinding media; Another drawback of the round table is invalid contact between the two tables in the existence of such invalid contact, affect the grinding efficiency, must be fully aware , so as not to step misunderstanding. Multifunctional grinding balls increase energy conservation principle, between the ball and the ball point, line and plane contact, regardless of the impact mill stripping material efficiency is higher than the spherical shape of ball short columns. In some factories, mines are currently being widely used.
