subject: Ball Mill's History [print this page]

Ball mill appeared in the early 19th
Ball mill appeared in the early 19th

century; 1870 in the mill, based on the development of a uniform size marker rod mill; in

1908 it created a self-mill without grinding media. 30 to 50 years the twentieth century,

the United States and Germany have developed a roll bowl mill, roller mill and other

vertical type disc pulverizers. This year is mine mineral processing equipment as an

essential part of the ball is more rapid development of the.

Ball mill is the material being broken, and then smash the key equipment. It is widely used

in cement, silicate products, new building materials, refractory materials, fertilizer, ore

dressing, and black glass ceramic and other non-ferrous metal production industries, and

other various ore grindability of materials for the dry and wet grinding.

Ball mill is a horizontal rotating device, outer gear, the two positions, lattice-type ball

mill. Material from the feed device into the compound by air evenly into the mill screw

shaft first warehouse, the warehouse there are ladder liner or corrugated liner, built in

different specification steel balls, cylinder to convey ball into the action must generate

centrifugal force After the fall height, produce severe impact on the material and abrasive.

To coarse grinding of materials in the first position after the board by the single

compartment into the second warehouse, the warehouse lined with flat lining, steel ball

inside, the material to further grinding. Powder discharged through the discharge grate

plate to complete the grinding operation.

Structural characteristics of ball mill from the feeding part, discharging Department,

Rotary Department, Transmission Division (reducer, small transmission gear, motors,

electrical control) and other major components. Hollow shaft with steel casting, lining

Replaceable, slewing gear hobbing by casting process, the body inlaid cylinder liner wear,

has good wear resistance.

Ball mill energy consumption in the course

of work accounted for the majority of the whole process of cement production, including

power consumption, integrated power consumption of cement accounts for about 60% -70%, so

how big the energy consumption of "downsizing" is a cement technology workers unremitting

goal. Grinding equipment selection, based on cement and concrete properties (performance,

mechanical properties, durability) as the core, not just the pursuit of the production

process of reducing power consumption, but also to meet the needs of building energy saving.

"Standard density is low, a good additive compatibility, well age, high strength, help to

improve the durability of concrete is the quality of cement concrete." At the same time,

also ensures the development of admixtures industry view, "admixture of cement industry can

reduce the required particle bound to improve the performance of cement plays an important

role."
