工作原理

主電機通過減速機帶動磨盤轉動，物料經螺旋輸送機進入立磨主機內，受重力作用落到磨盤中央，同時風機產生的氣流從進風口進入主機。在離心力的作用下，物料從磨盤中央向邊緣均勻移動，經過磨盤上的輥道時，受磨輥碾壓，大塊物料直接被壓碎，細物料受擠壓后形成料層，進行粒間粉碎。粉碎后的物料繼續向磨盤邊緣移動，直到被磨盤外圍的風口環引導的強氣流向上帶走，較粗的物料由于自身重力原因重新落回至磨盤內，進行再次碾磨；較細物料則隨氣流上升進入主機上方的分級系統進行篩選分級，在分級轉子葉片的作用下，較粗的物料不能被通過，而被葉片重新打落活磨盤內再次碾磨，合格的細粉將隨氣流帶出分級系統，通過外部管路進入除塵系統，然后經除塵器將氣流與物料分離、收集后，即為成品。另外，物料中的雜物及大顆粒物料會在研磨時，被刮料板刮入排渣口，排出磨體，從而有效的保證了成品的質量。此外還可通過調節液壓系統的壓力，來調節磨輥的壓力，在一定范圍內可適應不同硬度的物料需求；通過調節多轉子分級系統的轉子轉速，來調節分級篩選細度，從而獲得多種不同規格的合格成品。

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.
