Ball mill is a horizontal grinding mill and key equipment for grinding materials, widely used in ore flotation processing plant and powder-making production line. According to different materials and discharging methods, there are dry ball mills and wet ball mills for choice. Dry ball mill is mainly for producing mineral powder used in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry; Wet ball mill is a kind of continuous ball mill used in ore beneficiation plant. ...Learn More

Under the same air volume processing, it small volume, simple structure and low cost. 4. many set machines work together in parallel with same air volume processing, small volume, simple structure and low cost. 5. it can be resisted 400℃ high temperature, if adopts special high temperature resistance material, it will resist higher
The starting point for ball mill media and solids charging generally starts as follows: 50% media charge; assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space; add to this another 10%-15% above the ball charge for total of 23% to 25% product loading

Ball mill operation is often regarded as something of a mystery for several reasons. ball milling is not an art - it’s just physics. the first problem will ball mills is that we cannot see what is occurring in the mill. the other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results
Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. this paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor
