Wet Grid Ball Mill Capacity 0.5-500TPH Feed Size 25 mm. Grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. The size of ore shall not exceed 65mm and the best feed size is under 6mm.
The equation below shows the relationship between ball mill grinding efficiency and material fineness K d G 2 G 1 d 1 d 2 X 1 Note. K d the relative productivity of the mill G 1 amp G 2 respectively represent the mill output T h when the feed particle size is d 1 and d 2
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. The feed to ball mills dry basis is typically 75 vol.- ore and 25 steel.
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 K F dB ball size cm
Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mills output back to the ball mill for further size reduction. A typical closed system grinds the ore between two to three times.

Ceramic ball mill is the typical grinding equipment which us ball mill ceramics, greatly improves the grinding fineness. Compared with the traditional ball mill, such kind of ball mill has a great advantage in function, structure, and operation. This machine also has great capacity, high technology, and no noise, which plays an important role ...
Laboratory ball mills are scaled-down ball mills that use milling jars that are filled with grinding media and rotated using a jar rolling mill to reduce the particle size of the material. While they are commonly used for small size applications, options are available that
The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material feeders, and the system for discharging the output product.
Ball mill is mainly used for grinding in mining metallic minerals and non-metallic minerals, cement, refractories, chemical, power plant, aluminum ,building material, glass, ceramic, steel slag and fly ash, ect. It follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.
