A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

ball mills, but also from our comprehensive scope of services, ranging from maintenance and OEM spares procurement to the optimization of existing plants. The grinding unit most commonly used for grinding brittle materials, such as cement, is still the ball-filled ball mill. The following types can be found: • single-compartment mills,

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills over

cement plant, the kiln. Based on their design, it is critical to keep the kiln in motion at all times when heated. The inching drive for this application is designed to operate whenever main power is lost for the rotation of the kiln. The second cement application for inching drives is the rotation of the horizontal grinding mills for maintenance.
