Ball Mill's History
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."
