Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.

Ball mill is the key equipment for re-crushing 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 non-ferrous metals, and glass ceramic industry.

Ball mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding. Besides, it is mainly applied in many industries, such as ferrousnon-ferrous metal mine, building materials, chemical, electric power, coal, traffic, light industry

Ball mill introduction: Ball mill, a type of Grinding Mill, is a cylinder-shaped device used to grind materials like ores, chemicals, ceramic raw materials and paints. The ball mills are the key milling equipment after material has been crushed. It is divided into two rubbing way---- the dry and the wet.

Ball mill is used to fine grinding the ceramic materials. It is suitable for large building ceramic, sanitary porcelain, electric porcelain, ceramic tile, clay roof tile, terracotta facade panel, ceramic plate industry. TQ-0.5T ball mill is small clay roof tile machine and ceramic tile machine use to grinding glazes. Main technical parameter as

For the mill with higher mill load and lower speed, the power draw of the mill differed slightly for the different lifters with the same face angles of 20o. Rail lifter drew higher mill power and lower power for Hi-Lo lifter. The Hi-Lo lifter relatively indicated improvement in the energy efficiency of the mill approximately 22%.

A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power.. The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to

Charge behaviour and power consumption in ball mills: sensitivity to mill operating conditions, liner geometry and charge composition. International Journal of Mineral Processing, 2001. This is consistent with a peak motor power rating of 3.3 MW that would commonly be used for a mill of this size.

Planetary ball mills with up to 650 rpm motor power are available in various models with one button settings, adjustable parameters optional aeration lids locking lamps for inert atmosphere grinding. Mills with single, twin four station capacities are also available with grinding chambers to prevent contamination of samples.

Mills. Figure 2 shows a cutaway view of a Babcock and Wilcox MPS Pulverizer. Ring-Roll and Ball-Race Mills A ball or roller between two races or rings provides the grinding surfaces on which pulverization occurs. One or both of the races may rotate against a ball or roll (in a Ring-Roll Mill the rolls may rotate while the ring is stationary).

The ball mill is powered by a fairly robust 12V DC motor salvaged from a junked printer. It had a pulley for a fine-toothed belt on it. It was left in place and it seems to drive the heavy round rubber belt well without slipping. The motor was mounted using screws on
