RFLM series vertical mill RFLM SERIES ULTRAFINE VERTICAL ROLLER MILL RFLM series fine powder vertical mill, is Ruifeng powder equipment co., Ltd. Relying on many years of experience, and through in-depth study of Germany, Japan and other foreign powder processing technology, fully understand the needs of users, Understand the pain points of the industry. With the professional design concept, through the deep cooperation research and development with domestic and foreign parts suppliers, introduced a number of powder grinding equipment, widely used in calcite, barite, talc and other large-scale fine powder processing fields.

Working principle the main motor drives the grinding disc to rotate through a speed reducer, the material enters the vertical grinding host through a screw conveyor, and the material falls to the center of the grinding disc under the action of gravity, and the air flow generated by the fan enters the main machine from the air inlet. under the action of centrifugal force, the material is uniformly moved from the center of the grinding disc to the edge, and when the material passes through the roller way on the grinding disc, the material is crushed by the grinding roller, the bulk material is directly crushed, and the fine material is extruded to form a material layer, and the granules are crushed. the crushed material is continuously moved to the edge of the grinding disc until the strong air flow guided by the tuyere ring on the periphery of the grinding disc is taken away, and the thicker material is returned to the grinding disc again due to the gravity of the grinding disc to be ground again; the fine material is screened and classified along with the air flow rising into the grading system above the main machine; under the action of the graded rotor blade, the coarse material cannot be passed, and the blades are re-milled in the movable grinding disc again, and the qualified fine powder will be taken out of the grading system along with the air flow, entering the dust removal system through an external pipeline, and then separating the air flow and the material through a dust remover, and collecting to obtain a finished product. in addition, the impurities in the material and the large-particle material can be scraped into the slag discharge port by the scraping plate when the material is ground, and the grinding body is discharged, so that the quality of the finished product is effectively ensured. in addition, the pressure of the grinding roller can be adjusted by adjusting the pressure of the hydraulic system, so that the material requirement of different hardness can be met in a certain range, and the fineness of the grading filter is adjusted by adjusting the rotor speed of the multi-rotor grading system so as to obtain a qualified finished product with a plurality of different specifications. Our performance advantages 1. The product diversity is strong, the RFLM series grinding host is equipped with a new type of multi-rotor classifier, the particle size range of the finished product can be large, the interval between 2 & mu; m is 30-60%, the D97 is 7-45 & mu; m, the specific surface area is 20000cm/ g, and the product of D97 = 7.0. mu.m can be directly produced by the host. 2. With reasonable design and matching, the mechanical system has higher transmission efficiency, and adopts Honeywell or Siemens high energy efficiency motor as well as high-efficiency customized fan. The characteristic curve of the fan is designed according to the actual working condition of the vertical mill. Therefore, the energy consumption of the RFLM series vertical mill is lower, and the long-term operation can lower the power consumption cost of the enterprise. 3. The grinding wheel, the grinding disc, the flow guiding system and the internal circulating system after the improvement of the Company have higher grinding efficiency, and the yield is 10-20% higher than that of the past vertical grinding products. 4. The mill after the Companyundefineds improvement can be operated at low vibration with lower vibration and noise. 5. The speed reducer has the advantages of high reliability, no need of frequent oiling and maintenance, low failure rate, long service life of the grinding roller system, long service life of the bearing and the oil seal, The torque and performance are higher than the commonly used Grisson spiral bevel gear, and the gear material adopts the steel of DIN standard to ensure the long service life. The small-sized speed reducer adopts German SEW or Japanese Sumitomo brand, and the heavy-load grinding roller part adopts the American TIMKEN bearing, and the high-speed classifier part adopts the FAG bearing of Sweden SKF and Germany to ensure the long-term stable operation of the part. The drive part of the motor is the frequency converter product of the Japan undefinedan Sichuan Electric Machinery Co., Ltd. 6. The wear-resisting property and the riffon grinding and grading wheel adopt the high wear-resistant material and the heat treatment technology, have a long service life, the cost of the wear-resistant piece replacement is saved for the user, and the downtime maintenance time is reduced. 7. Intelligent, with PLC control and touch screen operation, the system can realize the automatic operation of the vertical grinding production line, display and save the running data in real time, such as speed, temperature, pressure and pressure difference, and can adjust the pressure parameters and pressure difference parameters according to the pressure parameters and pressure of each point collected by the system, The current parameters and the like realize the automatic feeding operation, and the automatic operation makes the original complicated vertical grinding operation simple. and can be connected with the internet to realize remote control, remote fault analysis and processing and data analysis.
