The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds.

Size Reduction. Tumbling Steel Ball Mills and Ceramic Lined Mills are one of the most precise, reliable and cost effective methods of fine grinding solids in either a wet or dry state. Ball Mills are referred to by many names including Pebble Mills, Tube Mills and Attrition Mills, but no matter what the nomenclature they all operate on the same

This approach has the added advantage in that different particle sizes can be effectively milled in a ball mill because each media size can effectively break a particular particle size during the size reduction process ensuring that the product fineness is optimized.

Size reduction merupakan salah satu operasi dalam dunia industry dimana komoditi pertanian dikecilkan ukurannya untuk menghasilkan suatu produk yang memiliki nilai mutu dan nilai tambah yang tinggi. Operasi pengecilan ukuran terbagi menjadi dua kategori yaitu untuk bahan padatan dan untuk cairan (Smith, 1955).

Rod and Ball Mills not so much however as their size reduction actions are hidden in the tube (mill). As for Rod Mills, the image above best expresses what is going on inside. As rocks is feed into the mill, they are crushed (pinched) by the weight of its 3.5” x 16’ rods at one end while the smaller particles migrate towards the discharge

Ball Size as Initial Charge. Commercial ball sizes 10 – 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d↓V = 0.40

The diameter of ball used will vary between 12 mm and 125 mm W o r k i n g The ball mill is used for the grinding of a wide range of materials and it copes with feed up to about 50 mm in size. The material to be ground may be fed in through a 60 degree cone at one end and the product leaves through a 30 degree cone at the other end.

Principle of Ball Mill : Ball Mill Diagram. • The balls occupy about 30 to 50 percent of the volume of the mill. The diameter of ball used is/lies in between 12 mm and 125 mm. The optimum diameter is approximately proportional to the square root of the size of the feed. The shell is rotated at low speed through a drive gear (60-100 rpm) and
