High drying efficiency, Low running cost, Good environmental effect
LM Vertical Mill integrates crushing, drying, grinding, classifying and conveying together, and it is specialized in processing non-metallic minerals, pulverized coal and slag. Its coverage area is reduced by 50% compared with ball mill, and the energy consumption is saved by 30%-40% similarly.
Applications: Cement, coal, power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.
Large capacity, Low consumption, Environmental friendly
MTW European Trapezium Mill has a large market share in the grinding industry. Whether bevel gear overall drive, inner automatic thin-oil lubricating system or arc air channel, these proprietary technologies makes machine advanced, humanized and green.
Applications: Cement, coal , power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.
Little abrasion wear, Long service life
Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.
Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.
MILL STEAM INERTING SYSTEM REQUIREMENTS . In addition to the requirement by NFPA 85 for inerting a tripped mill system, coal mill OEMs usually recommend that a mill system be inerted during both the normal mill start-up and shut down process.

Jan 07, 2016 Indonesian coal is known to have low dust and sulphur contents and these are very desirable properties e.g., burning low sulphur steam coal produces less sulphur dioxide. However, lower rank coals have higher volatile contents and many Indonesian low rank coals have high resin contents both of which are undesirable.

The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from 1.75 to 2.2 with a typical value of 2.0. An air to fuel mass ratio of 1.8 produces a primary stoichiometric ratio of approximately 0.16, or 16% of the air necessary for complete combustion of the coal.

Properties of Coal • Coal properties are evaluated by different methods. • The most commonly used methods are Proximate and Ultimate analysis of the coal. • Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. • Ultimate Analysis gives the elemental composition of the coal. • Other methods like Macarel analysis is also used
