WhatsApp: +86 18203695377Ball mill drums offer an efficient and inexpensive way to grind materials down to a more usable size, often as fine as 2575 microns. Both continuous and batch style ball mills use centrifugal force, gravity and hard media to break up industrial materials into fine pieces or powder. Ball milling systems grind dry material and wet slurry alike.
WhatsApp: +86 18203695377The Drum Mill TM 500 is a laboratory ball mill suitable for grinding large sample volumes of up to 35 l. This mill accepts initial feed sizes of up to 20 mm and can achieve grind sizes down to 15 µm by the friction and impact. Hard, brittle or fibrous samples are pulverized in the 150 l drum filled with 80 kg grinding balls.
WhatsApp: +86 18203695377The grinding process in the ball mill is due to the centrifugal force induced by the mill on the balls. This force depends on the weight of the balls and the ball mill rotational speed. At low speeds, the balls are at a fall state (Figure 9(a)). As the operating speed increases, the balls reach a higher helix angle before falling and repeating ...
