Ball Mill Application Areas

1) Ball mill in cement grinding

Cement grinding is the final process in cement manufacturing, which cost the most electric power. Its main function is to grind cement clinkers into the required size. Ball mill can be used in this process.

2) Ball mill in silica grinding

Ball mill can grind silica into powder with the required size. Silica, also called silicon dioxide, is an oxide of silicon with a chemical formula of SiO2 and 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.

3) Ball mill in limestone grinding

Ball mill can grind limestone into powder. 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 cpainting industry to enhance the performance of quality paints.

The development of vertical mill

The first vertical mill is developed and manufactured by Germany in 1920s. It’s said that the first vertical works like grain grinding mill. Having overcome many disadvantage of ball mill, vertical mill has high efficiency and low power consumption. The roller compacted materials directly onto the millstone, so power consumption is low. Compared with ball mill, it saves energy consumption by 20% ~ 30%. Besides, vertical mill has many advantages like high drying ability, simple and reliable operation, the stability of product quality, occupation area, maintenance convenience, low cost and low noise.

In recent years, with the rapid development the R&D technology of grinding machinery, the technology of abroad vertical mill manufacturers has become very mature, and its technical advantages have become increasingly prominent. In this situation, the domestic grinding mill enterprises learn from the foreign successful experience, carry out major technological innovation and also re-launched their own new vertical mills with patented technologies. The vertical mill is gradually accepted in the domestic cement, power, chemical industry etc. become the industry preferred grinding equipment.


Ball Mill vs. Roller Mill: Advantages and Disadvantages

Ball mill is a traditional mill machine widely used for mining, cement, paints, pyrotechnics, and ceramics industry. High Pressure Suspension Mill (a kind of roller mill) is a kind of new type mill, improved on the basis of Raymond Mill, with five rollers, produced by Henan Liming Heavy Industry.

Some customers asked us what is the advantage and disadvantage of them two. I arranged some information following for reference.

Advantages of High Pressure Suspension Mill:

(1) Cost of high pressure suspension mill is much lower than cost of ball mill because of after you buy this mill, it is not necessary for you to buy more accessory equipments.

(2) Power consumption of high pressure suspension mill is lower.

Disadvantages of high pressure suspension mill:

(1) The mainly disadvantage is that it will add iron content for products during milling process. But you can use one magnetic separator to reduce the iron content in the final products

Advantages of Ball mill:

(1) Ball mill with ceramic liner and ceramic balls, the finished product size will not add iron content.
(2) Ball mill is commonly used for process quartz to sand.

Division of industrial mill machine by output size

Indsutry mill can divided to following stages by output size:

1. coarse grinding: raw material size in the range of 40-1500mm,the finished product size is 5-50mm
2. medium grinding: raw material size in the range of 10-100mm,the finished product size is 5-10mm
3. fine grinding: raw material size in the range of 5-10mm,the finished product size is under 100μｍ
4. super fine grinding: raw material size in the range of 0.5-5mm, the finished product size is under 10-25μｍ

Under the above division, you can choose the proper type grinding mill for your business requirement. Henan Liming Heavy Industry produces many types grinding mill for process limestone,barite,marble,granite,kaolin,calcite,and other hardness ore, the main equipment are raymond mill, super pressure suspension grinder mill, super fine grindier mill, super pressure trapezium grinder mill,vertical mill,ball mill,etc.

Trapezium Grinder Mill: output size in the range of 1.6-0.045mm,the fineness can reach0.038mm

Vertical Grinder Mill: output size in the range of 0.045mm(325mesh),the fineness can reach 1250mesh.

Raymond Mill: output size in the range of 613-440μｍ(1.613mm-0.44mm),100-425mesh.

High pressure suspension grinder mill: finished product size can be adjusted in the range of 80-425mesh(fineness can reach1000mesh.

Super fine grinder mill: output size in the range of 5-45μｍ(325-3250mesh)

Note :Pleae keep in mind hardness,humidity,toughness of material will influence the production capacity and output size.
