Ball Mills The final stage in comminution are performed in ball mill. Balls have a greater surface area per unit weight than rods better for fine grinding. Length to diameter ratio (L/D) is to 1 and less. If L/D is 35, called tube mill or pebble mill. The grinding mediums are pebble or flints. It is widely used in ceramic raw material.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency [5]

Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power is not fully established. One area that is usually ignored is the relationship between

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.
Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include: Speed of mill rotation; Mill diameter; Mineral density;
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.

Apr 09, 2015· Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are more suitable for fine grinding. Balls are also lighter, so the kinetic energy of a single dropping ball is smaller than a rod.
Surface area, size distribution of the product power consumption and the following parameters: 1. Effect of time of milling, 2. Effect of the size of balls, 3. Effect of feed quantity, 4. Effect of feed size 5. Correlation for Specific Surface Area Effect of time of milling: The effect of time of grinding in a ball mill has been studied
Decreasing the rod size from 3 to 2½ inches (76 to 64 mm) at Tennessee Copper resulted in an increase of 22% in rod consumption, which can be directly attributed to the larger exposed surface area of the grinding media. This strongly supports the general practice of selecting large rods, but should be considered in conjunction with mill ...
