how to design a ball mill

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs.

Please find below two calculators for sizing mills using the Bond and Rowland methods: Ball mill sizing: Calculator for ball mill(s) in a single stage circuit. Rod ball mill sizing: Calculator for rod mill(s) as first stage of the circuit and ball mill(s) as second stage of the circuit.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

DESIGN OF A BALL MILL TYPE ATTRITOR FOR THE PRODUCTION OF MECHANICAL ALLOY ... a cannonball mill for the production of mechanical alloys with technology and materials available in .

Ball mill. A typical type of fine grinder is the ball slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

The High Energy Ball Mill Emax combines highfrequency impact, intensive friction, and controlled circular jar movements to a unique and highly effective size reduction mechanism. The grinding jars have an oval shape and are mounted on two discs respectively which move the jars on a circular course without changing their orientation.

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 mill is the key equipment for recrushing the materials after they are primarily crushed. Ball mill is widely used for the dry type or wet type grinding of all kinds of ores and other grindable materials in cement, silicate product, new building material, refractory, fertilizer, black and nonferrous metals, and glass ceramic industry.

Working Principle: Laboratory Ball mill consists of cylindrical shell rotating on a horizontal axis mounted on a sturdy mild steel frame. the ball mill shell is designed to withstand the rotational load of the mill charged with the grinding medium and the material to be processed.

Steel mill liners with optimized design. The large mills of today process high tonnages, and every minute of production counts. Proper material selection, optimized liner design and constant design improvements are the keys to successful grinding. offers steel liners that keep your mill .

3 The design offers such benefits as: xElimination of castings and the structural risk associated with them. xFeed and discharge designed to process requirements rather than to restrictions imposed by trunnion bearings. xMinimised risk of feed blockage through short trunnions. xQuick accessibility to mill interior. xLighter weight and lower number of flanges for ease

With applications such as lime slaking or limestone grinding, smaller capacity ball mill systems are often required. In these instances, a cost effective option, when compared to larger trunnion mounted mills, is a roller mounted ball mill. This design uses heavy duty support rollers to drive the rotation of the mill .
