This accurate scale up is different than scale up for ball mills or other stirred milling technologies. in ball mill laboratory tests 25mm balls in a small laboratory ball mill have different trajectories and interact differently with the shell lifters and ore particles than in a large production ball.
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball.
When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. new feed entering at one end of the mill causes the rod charge to spread at that end. this produces a series of wedge shaped slots tapering toward the discharge end. the tumbling and rolling rods expend most of their crushing force on the.
[introduction]: a ball mill with simple structure and auto-flowing pulp discharge. [capacity]: 0.17～170t/h [improvement]: overflow type ball mill is equipped with slow transmission system.when the ball mill starts, the low-speed slow transmission runs first, and the high-speed main motor drive system runs later, which not only saves energy, but also reduces the impact on the ball mill.
