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.
2021-7-29 This is one of the disadvantages of AAC Blocks. Prevention: Due to the low compressive strength of AAC Blocks, the wall height should be limited to 1000 mm to 1200 mm. When we use AAC blocks, after every 1200 mm height of the wall, we must provide a “Band Beam” as shown in the figure. This band beam distributes the loads uniformly

2 天前 “What are the disadvantages of AAC blocks?”, AAC blocks are formed by pouring foam concrete into a mould then setting them until the desired strength is attained. To understand AAC blocks one must understand the basics of foam concrete. It is formed by adding a foam (something similar to the shaving foam we use) to a cement-flyash slurry.

The AAC blocks making ingredients are all inorganic and non-combustible. This means they will not produce poisonous gases and fire-resistant up to 1600°C. The fire resistance duration depends on the thickness of the wall, a 100mm thick wall can withstand up to 4 hours of direct exposure, thus meeting building codes for building fire protection.
