Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotationa portion of the charge is lifted along the inside perimeter.
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.
May 222019 The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotatedthe grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.
involve grinding). With Lloyds ball milling book having sold over 2000 copiesthere are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyds researchwhich was obtained from the commercial ball milling industryand explains some of the key design criteria for making your own ball mill.
Short Cylinder Ball Mill: The ball mill with the cylinder length (L) less than 2 times of the cylinder diameteri.e. the ball mill with L 2D is short cylinder ball millwhich is usually of single bin structuremainly used for rough grinding or primary grinding operationand can realize the wide use of 2-3 ball mills
Jul 182016 Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
The overall design of ball mills and rod mills are compactwith simple operation and easy maintenance. But the both are different in performance and applications. In this articlethe similarities and differences between ball mills and rod mills are analyzed from 9 aspectsand suggest how to choose ball mill or rod mill.
