This slide is used to launch a ball, as shown in Fig. 4 (b). The ball is dropped from the slide, three times within a 10 s period, onto the inverted test plate. If any of the aggregate particles are not well adhered to the bitumen film on the plate, they will drop to the ground upon the impact of the dropped ball.

Ball mill. The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but ...

The three main mill options for phosphate ore are: Ring-roller mills: Vertical rollers rotate inside a fixed horizontal ring (Figure 1). Material fed between the rollers and the ring is ground to powder. Ball mills: A horizontal rotating cylinder contains a charge of steel balls. These balls tumble as the mill turns so that material caught ...

The size of the blind trommel and magnetic circuit can be varied to retrofit an existing ball mill and available space at the discharge. The magnetic circuit is designed to provide maximum strength for high slurry throughputs and up to 4 inch diameter grinding balls. The trunnion magnet can be configuration for reversing or bi-directional mills.

Increased mill capacity can be achieved by upgrading an existing classifier or replacing a current one with a high-efficiency classifier, such as the BLVT. Capacity improvements can be expected in the 15% to 17% range. The superior design provides controlled and guided material flow right up to and through the classifier.
