    Jul 05, 2020 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

    Jul 05, 2020 Hammer mill is the most widely used grinding mill and among the oldest. Hammer mills consist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact. The materials to be milled are struck by these rectangular pieces of hardened steel (ganged hammer

    Dec 10, 2018 Dec 10, 2018 The difference between a roller mill and a hammer mill is: A hammer mill uses rotating hammers to pound grain through a screen and it requires a lot of horsepower. A roller mill uses cylindrical rollers that grind the grain when it goes through them, which requires less horsepower then a similar capacity hammer mill
