HLM series vertical mill is a large-scale advanced,high-efficiency and energy-saving grinding product developed by China Henan Fote Group using the world's advanced material bed grinding and partial external circulation technology,combined with more than 40 years of experience in mill production and manufacturing of China Henan Fote Group.Grinding,grading,drying and conveying are integrated,with independent intellectual property rights,and the core technology and economic indicators have reached the international advanced level.
1.Clean and environmental protection
The whole system operates under complete negative pressure,with reliable sealing,no dust spillage,and clean environment.The collection of finished products adopts a bag-type dust collector,and the dust removal efficiency is as high as 99.9%,which is higher than the latest national environmental protection standard;
The limit device of the HLM mill ensures that the grinding disc and the grinding roller do not contact during the working process,with low vibration and low noise.
2.High efficiency and energy saving
High grinding efficiency,low energy consumption,30% 50%less power consumption than ball mills,excellent roller disc structure design,long grinding curve and large grinding area;
Equipped with a hydraulic loading system,the grinding pressure can be flexibly adjusted according to the change of grindability,which is highly efficient and energysaving.
3.High degree of automation,simple operation and maintenance
The automatic control system is adopted,which can realize remote control,which is simple and convenient;
The limit device prevents the direct contact of the grinding roller and the grinding disc,and can be started without load,without the need for distributing materials before starting the machine;
External independent thin oil lubrication station is installed to facilitate oil replacement.Both the reducer and the roller bearings are lubricated with forced thin oil,which takes away a lot of heat while lubricating and improves the service life of the reducer and roller bearings;
The hydraulic maintenance device can easily tum the grinding roller out of the machine,and the replacement of the grinding roller sleeve and the maintenance of the grinding roller are convenient and quick.
4.High quality,low cost
4.1Product quality is stable and reliable
Adopt dynamic and high-efficiency powder separator,with concentrated particle size distribution,good particle shape, frequency conversion speed regulation,and easy adjustment of product fineness;
At the same time of grinding,the finished product is selected in time,which reduces the residence time and cycle times in the material mill,and the finished product has less pollution and high quality.
4.2 Low comprehensive investment cost
Due to the integration of grinding,grading,drying and conveying,the process is simple,the layout is compact,the floor area is small,and it can be arranged in the open air, reducing the construction cost;
With drying function,it can be ventilated with hot air,and it can be directly and repeatedly contacted with powdery materials for drying in the mill,saving a set of drying equipment.By adjusting the hot air temperature,it can meet the drying requirements of materials with different humidity, and can meet the drying requirements of materials with humidity up to 15%.
