(1) Ball mill is an efficient equipment for grinding many materials into fine powder.

(2) The ball mill is used to grind many kinds of mine and other materials.

(3) Ball mill is widely used in building material, and chemical industry.

(4) There are two ways of grinding: the dry way and the wet way.

(5) Ball mill can be divided into tabular type and flowing type according to different expelling mine.

(6) To use the ball mill, the material to be grind is loaded into the neoprene barrel that contains grinding media.

(7) As the barrel rotates, the material is grinded between the individual pieces of grinding media that mix and grind the product into fine powder over a period of several hours.

(8) The longer the ball mill runs, the finer the powder will be.

(9) Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the ball mill runs.

Materials enter into the first grinding chamber through hollow shaft. There are liner of ladder type or curve type, and steel balls of different specifications in the first grinding chamber. The centrifugal force caused by turning of he barrel take balls into a certain height inside the chamber, and then balls fall down, have striking and grinding effect on materials. Materials after primary grinding in the first grinding chamber is fed into eh second grinding chamber through single layer chamber dividing plate. There are flat liners and steel balls in the second grinding chamber. The balls make further grinding effect on materials. Finished powder which meet requirement is discharged through discharge grade plate and the grinding work is finished.

1. Ball mill can be used in cement grinding

Invention of cement provides a material basis for the development of construction. From land engineering to water, underground engineering, and cement plays an important role. Cement has been invented for a hundred years and it has always been the most widely used the most consumed binder. In order to meet the needs of different construction, the increasing variety of cement has reached more than 200 kinds. Ball mill is an important equipment to grind cement.

2. Ball mill can be used to grind silica

Silica, also called silicon dioxide, has been known for its hardness since antiquity. Silica powder is widely used in the production of glass for windows, drinking glasses, beverage bottles, and many other uses. The majority of optical fibers for telecommunications are also made from silica. It is a primary raw material for many whiteware ceramics such as earthenware, stoneware, porcelain, as well as industrial Portland cement. Ball mill is an important equipment for grinding silica.

3. Ball mill can be used to grind limestone

Limestone often contains variable amounts of silica in the form of chert or siliceous skeletal fragment, as well as varying amounts of clay, silt and sand sized terrestrial detritus carried in by rivers. Limestone powder can be used as filler in painting industry to enhance the performance of quality paints. Ball mill plays an important role in grinding limestone.
