【正文】 me measure to leave the grinding disc, starts the main motor and the motor of the separator, and noload operates 6 hours, and pay attention to the whole operating process that there is no any abnormal sound or phenomenon. Else wise the machine should be stopped immediately. The rotary speed of the separator should be from the small to the big, before operating the main motor the switch should be started, and look the rotary direction of the motor if is right.d. The preparation before the operating equipment (1) Firstly examine the rotary parts if can normal operation and if the lubricating points have injected the suitable lubricant oil. (2) Next the clearance between the grinding disk and the grinding roller is 10mm through adjusting the limit device. (3) At last the accumulator should be charged the gas, its pressure can refer to the usage instructions of the accumulator. The hydraulic system is placed in to the normal working state.e. The order of the operating equipment The motor of the lubricating system(thin oil station) motor of the separatorraising rollermain motorfeed and fall roller off the motor of the hydraulic systemf. The illustration of the operation: After starting the mill, the material feed with a fixed value, operate the hydraulic system to make the grinding roller fall off, start the motor of the oil pump of the hydraulic station, adjust the working pressure of the hydraulic system, to make the system reach the balance, meanwhile the rotary speed of the rotor of the separator should be adjusted, and make the fineness of the products can satisfy the requirements.( firstly the rotary speed of the separator should be adjusted into the maximum, according to the fineness of the products adjust the rotary speed) 2. While carrying through the above operation, the current of the main motor should be noticed, the bush of the main reducer is less than 70 degree and the temperature of the bearing of the grinding roller is less than 100 degree. 3. According to the moisture of the material, the temperature of the feed gas should be adjusted, and the maximum can not be more than 350 degree. 4. The feeding capacity of the mill, the grinding pressure, the ventilation quantity in the mill, the rotary speed of the separator and so on should be considered together, and make them locate in the excellent cooperating state. g. The matters of the maintenance: after operating period of time, the connecting bolts and the fixed bolts should be examined if there is loose or damage。 the abrasion conditions of the seal parts and the wearing parts should be inspected。 the lubricant oil or lubricant grease should be provided for the lubricating points regularly。 the clearance between the lining board and the roller sleeve should be adjusted according to the abrasion conditions of the roller sleeve。 after the mill operated 500 hours, the oil in the main reducer should be exhausted and cleared out, then change the new oil, after then the oil quality should be examined in every 2000 hours, if the quality of the oil is not in accordance with the requirements of the standard, it can change。 the roller sleeve can turnover to use after the abrasion, if there is another abrasion, it should be changed. VI、List of main hydraulic lubricant equipment and lubricant oil products Install operation of hydraulic lubricant system for vertical mill scope of hydraulic lubricant for vertical mill：1） Hydraulic control station of main roller and assist roller。Lubricant control station of main reducer。 Spindle bearing lubricant control station of separating mill. 2） All pipeline install between control station and main parts of machine.3） Pipeline clean of hydraulic system and lubricant system.4） Each control station may be installed separately and put on the flat table or in the ground pit. of pipeline： Pipeline of hydraulic system and lubricant system all adopt seamless steel tube. They are connected with welded joint. Cleaning the pipeline with kerosene before install and then blow it with clean and dry air. Pipeline must be cold bending by bending pipe machine. It is not allowed bend with fire. Bending radius is no smaller than three times of pipe diameter. 3. System infuse oil：Before infuse hydraulic oil and lubricant oil,oil case must be cleaned with noodle the meantime must be passed by filter . Precision of filter is . It is not allowed infuse oil to oil case directly.PS：Hydraulic lubricant list of equipment1Hydraulic station of grinding roller load N46hydraulic oil proof grinding200L3 months Lack of plementary oil or oil dirty need to replace2 Main lubricant control station ISO VG3201500L3 months Lack of plementary oil or oil dirty need to replace3Lubricant station of separated device ISO VG320300L3 monthsLack of plementary oil or oil dirty need to replace4Grinding roller bearingISO VG320suitableVII、List of bearingsNoBearing positionModelQtyRemark1Grinding Roller deviceSphere roller 536484GB286642Spindle of separate device Taper roller 303191GB/T297943Spindle of separate deviceColumn roller NU2219E1GB/T283944Main oil cylinder Joint bearing GE110ES2RS4GB9163905Auxiliary oil cylinderJoint bearing GE50ES2RS4GB916390VIII. Services:1. According to the different conditions of the material, the technical skill and equipment for the plete set of the vertical roller mill should be provided.2. The installation and the debugging can be provided freely. (One mechanical engineer, one electrical engineer)25 / 25
