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.

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.
03/10/2002 RE: Suction Header Design. vanstoja (Mechanical) 29 Sep 02 18:44. To keep the velocity in the inlet header at the same 9.84 ft/sec inlet velocity to the three pumps you need a 13.86 inch ID header if the 8-inch pump inlet diameter is in fact the ID and not the OD of the piping. The magical equation is Velocity =Flow/Area.
get priceAn important aspect of pump hydraulic system design is the suction or inlet conditions. Disregard for proper allowances can result in vortices, cavitation, and loss of prime. Pumps do not force liquids through inlet or suction piping, but rather create lowered pressures at the suction nozzle which in turn in-duces the fluid to enter. Any design that impedes or lessens the efficient transport

Your suction pipe has a certain diameter which must consider the total flow of all pumps that can run in parallel in respect of fluid velocity. Your header should be of the same size
get priceThe suction tank fluid provides pressure energy to the pump suction which helps the pump. We want to know how much pressure energy the pump itself must supply so therefore we subtract the pressure energy provided by the suction head. The static head is then the difference in height of the discharge tank fluid surface minus the suction tank fluid surface. Static head is sometimes called total
