With the demand for more and more large-scale milling technology growth, vertical roller mill is also the industry constantly fling, with a good performance, in large slag, cement, power plants and other industries irreplaceable important position, relatively speaking vertical mill operation is quite strict, especially to the majority of readers of this article describes nine points before the slag vertical mill started operations.

① lubricants inspection and adjustment vertical roller mill lubrication system. Lubrication equipment to ensure long-term stable operation of the equipment plays a key role, on the one hand, the amount of lubricant neither too much nor too little. Lubrication excessive heat will cause the oil equipment. too little oil, equipment damage due to lack of oil on the other hand, to regularly check oil change, oil varieties, label can not be wrong, can not have impurities and oil, lubrication equipment oil check must be fully exhaustive manner, including air lock lubrication, roller lubrication, gear box lubrication and hydraulic oil, oil, valves, etc., all the moving parts, so that the moving chain, couplings should refuel.
② vertical milling machine to check the cooling water cooling water is essential for equipment protection, should be checked before starting the main gear and roller lubrication, cooling water on the road hydraulic valve lock valve is open the cabinet and controls appropriate traffic.
③ vertical milling machine air compressor, tank and pipes and valves checked. Compressed air compressor station is to start checking whether each according to the provisions of the sewage tank pressure reaches the rated pressure, compressed air piping and valves without leakage phenomenon, there are problems in time, hand valves on the gas pipeline should be in the open state.
④ debris off the inside vertical milling machine raw materials warehouse, internal equipment, the Confucian, check to check the door. Should be removed before installation or maintenance feeding raw materials warehouse, the warehouse mouth to prevent clogging or metal objects into the raw mill in before starting on the inside of the machine should also conduct a comprehensive inspection, installation or maintenance clearing out debris inside the device to prevent loss stuck or broke device equipment running.
⑤ vertical milling machine check valve positions under various raw bar open all valves or gate valve to the appropriate position; All manual valves before starting the device should hit the proper position; all electric, pneumatic valve system at the scene confirmed flexibility action, the valve shaft and connecting rod is loose, and then remotely operated by the central control room, control and confirm the opening and closing scene in the same direction, check the opening and labeled accurately, if the valve has to drive upper and lower limit switches, and the control room will have to check whether its limit signal returns.
⑥ fastening vertical milling machine inspection equipment. Mills, fans, compressors, etc. can not bolt loose, easy to loose pieces of equipment, such as to be movable link stringent checks should be carried out, hoist Satoko and also check the connection between the chains.
⑦ vertical milling machine raw material warehouse inspection. Recognizing the raw material storage bin accurate, level meter to accurately indicate the positions of material means, and with the control display consistent positions within the material produced during the test should not be too full, usually Mancang 60% to 70%.
⑧ vertical milling machine raw mill and ancillary equipment inspection apparatus according to strict check and confirm its integrity.
⑨ vertical milling machine raw meal silo checking raw material reservoir bottom breathable layer without damage, the library and the inflatable chamber without water, there are problems and timely treatment;. Library roof, the library side of the water intact; pipe connections accurate resistance pressure test without leakage; library free of debris; library must be dried before feeding raw material base for the first time, after drying raw material library, all the holes closed.
