The GRMR5341 type raw material vertical mill designed and manufactured independently by GREAT WALL was put into operation in a line of Henan Meng Eletric Group Cement production line expansion project successfully, and every index of it has reached international advanced level.
With advantages of low energy consumption, high grinding efficiency, strong drying capacity, simple system flow, large-scale production capacity, and so on, the vertical mill system has become the core equipment in the grinding system of the cement industry. Although the European suppliers have dominated the supply of such large-scale equipment for a long time, under the background that China's industry is growing from greater to stronger, vertical mills made by Chinese manufacturers have been developing rapidly today. With long-term commitment to research and development of new technology, Great Wall is also making great efforts to develop vertical mill.
The grinding table diameter of GRMR5341 is 5300mm, installed power is 3800 ~ 4100kW, hence it can support the 5000 ~ 6000t/d clinker production line in its raw material preparation system. After the GRMR3641 raw material vertical mill supporting 2500t/d clinker production line put into operation successfully, GRMR5341 raw material vertical mill began feeding operation in November 2009, and with the fineness of product being 80μm at 12%~15% sieve residue, the production capacity of the system kept stable above 460t/h. Up to now, this raw material preparation system of vertical mill has been running smoothly with easy operation, and its vertical and horizontal vibrations are both less than 1.5mm / s. The Owner praised the outstanding performance of this vertical mill, and it's also the largest vertical raw mill made by Chinese manufacturer that has been put into operation.
Vertical mill researched and manufactured independently by Great Wall for slag and cement clinker grinding has been put into operation soon as well in 2011.
With our specialized technical team and wealthy practical experience, we have developed successfully the GRMR series vertical raw mill and vertical mills applicable for cement and slag grinding, which has greatly promoted the development of grinding technology for the cement industry globally. It has great significance and far-reaching impact on domestic fabrication of large core cement equipment, the structure adjustment and further promotion of energy saving in China's cement industry.
The picture shows the GRMR5341 type raw material vertical mill is running in Henan Meng Eletric Group 5000t/d clinker production line.
