What type of mill is suitable for the production of alumina ultrafine powder?

The competition is increasingly severed in milling industry. Guilin Hong Cheng launches a type of vertical mill with excellent performance which is the best choice for alumina ultrafine powder producing enterprises.

Alumina is important raw material in industry, alumina industry’s healthy development is crucial to the economy. Alumina ultrafine powder producing enterprises usually pay much attention to the output grain size of alumina ultrafine powder, now the environmental protection &energy consumption are paid equal attention to .The reason for this is not only because enterprises respond to national energy saving and consumption reduction initiatives, but also because it is an opportunity for industrial transformation, environmental protection performance is a new reference standard for mill choosing.

Guilin Hong Cheng launches a type of vertical mill with best performance in milling industry, it has the following advantages: high output, easy adjustment of grain size, equipped with new type roller sealing device pulse powder collector which contribute to 99.9% powder collecting rate and zero dust emission workshop, energy consumption 40-50% lower than common ball mill, its energy consumption standard is much higher than national standard for energy saving and consumption reduction.

Guilin Hong Cheng alumina vertical mill: HLM vertical grinding mill

Feeding material grain size: 0-50mm

Millstone median diameter: 800-5600mm

Feeding material moisture : <15%

Finished product moisture : <=1-6%

Capacity: 5-700t/h

Application areas: nonmetallic minerals with Mohs hardness below 7,moisture below 6%,widely used in the areas of: electric power, metallurgy, chemical industry，rubber, coating material, printing ink, food, medicine etc.

Performance features: an integration of drying ,grinding, classifying and conveying, with the advantages of high efficiency, low energy consumption, large grain size, easy adjustment of fineness, simple process flow, space saving, low noise, less dust emission, easy maintenance, low running cost, less consumption of wear parts etc.

The working principle of alumina vertical mill:  the motor drives the reducer to rotate the millstone, the materials which are pushed to the space between rollers and millstone by centrifugal force are crushed, ground and smashed. Then the blower blows the powder to classifier , the large grain size powder falls down to be reground and the fine powder goes into pulse powder collector and is blown out through the pipes as finished product, the purified air is blown out through the pipes  above the pulse powder collector.
