1.scope of application
mls vertical roller mill is mainly used for grinding cement raw meal, and can also be used for milling systems in construction, chemical, ceramic and other industries.
2.model and specification
model: mls1411～mls4531a
motor power (kw): 225～3600
3.product introduction
in december 1985, nhi signed a technology transfer contract for introduction of mps vertical roller mill with german company, which introduced all the design, manufacturing and inspection technologies of vertical cement mill for raw meal and clinker of 8 specifications, as well as a complete set of laboratory equipment for the test and selection of mps32 mill to meet the needs of the cement production line pulverizing system of 700t/d, 1000t/d, 1500t/d and 2000t/d.
based on the introduction and absorption of international advanced technologies, after nearly 30 years of continuous innovation and research, a series of high-efficiency energy-saving mls raw material vertical roller mills with complete independent intellectual property rights have been formed. the main technical indicators and economic indicators have reached the international advanced level, which can meet the needs of raw material preparation of cement production lines below 7500t/d, and have made great contributions to the localization of equipment cement industry in china.
technical characteristics
mls vertical roller mill is a major raw material grinding equipment in the new dry production process of cement clinker in china building materials industry. it adopts the internationally advanced laminated grinding technology, which integrates crushing, laminated grinding, rapid drying, efficient powder separation and other processes. it has simple process and small floor area, and is an efficient, energy-saving and environment-friendly product, at the same time, it is also a high-tech product integrating many world advanced technologies such as high-efficiency grinding and high-efficiency powder separation.
mls vertical roller mill is designed according to the principle of low speed and large roller diameter. compared with other types of raw material mills, it has strong adaptability to the change of raw material; the output of the grinding parts is stable during the service life, and the output of the grinding parts decreases only 5% in the later stage of wear; with hydraulic loading, heavy load start light load roll lift start can be realized, so that the mill can operate stably under the most economical conditions; adopt dynamic and static separator; according to different grinding materials, grinding roller liner and grinding plate liner are made of high chromium cast iron, hard nickel cast iron (ni-hard iv) or hardfacing cemented carbide and other materials to ensure long-term stable operation of the mill.
