For heavy industrial machinery, it gives the impression of being bulky, whether in terms of volume or working principles and operating methods, it gives the impression of being very troublesome. So how to simplify the "heaviness" of a vertical grinder? Take a look at the following mnemonic!

　　1、 Vertical grinder structure:

　　The vertical mill consists of nine large blocks, with a frame, foundation, sealed pipe, grinding disc, grinding roller separator, and transmission lubrication tensioning rod. 2、 Working principle of vertical grinder:

　　The motor rotates with deceleration, and the force on the umbrella teeth is critical; The deceleration belt rotates with the grinding disc, and the grinding disc rubs against the grinding roller; The material is squeezed in the middle, and the force comes from the pressure frame; The work relies entirely on the tensioning rod, and the final output is the high-pressure pump; The lower support grinding disc and upper pressing frame rely entirely on this force to grind the powder; The fluctuation of material wave force is buffered by the accumulator; When the material is large, it absorbs; when the material is small, it returns; Seal the grinding roller and turn on the fan, and extract dust from the outer drum inside; Material drying nozzle ring, the wind speed is very important; Small materials to the upper part, coarse and fine adjustment separator; The material is transported to the middle and then enters the grinding disc for further grinding; The large material flows to the lower part and enters the grinding chamber for recycling. 3、 Operation essentials of vertical grinder:

　　The vertical mill operation involves three adjustments: adjusting the wind, seasoning, and speed; To ensure stable system operation, both the kiln mill and the air supply should be taken into consideration; To improve fineness, speed up the separator; Anti vibration, with multiple factors, the thickness of the material layer should be moderate; Generally, a thickness of sixty is controlled to ensure stable feeding without shaking; Large blocks of materials are not allowed to enter, and only materials below 90 are qualified; The air grinding vibration is hard against hard, and the full grinding roller should bounce; The tension of the pull rod should be balanced, neither too high nor too low; The pressure difference inside the mill should be stable, and the ventilation should be sufficient without imbalance; There is a reason for the large amount of slag being ejected, such as small air flow at the nozzle and excessive material feeding; Control the hydraulic tension force and select the middle of the oil pump pressure; The load is too high to operate, and the current should not exceed the rated value. The sealing pressure should not be too low, even as low as 5000 Pa.

　　4、 Start stop procedure for vertical grinder:

　　Prepare for the start-up of the grinder, and ensure that the oil level valve is in place; The bedding materials need to be laid sufficiently and checked when they are ready; The oil and water circuits are blocked, but the oil station filter is not blocked; Is the tension pressure sufficient? Can the gate pressure be adjusted; The grinder looked at the system and found that the front and back of the host should be coherent; The raw material warehouse is not full, and the raw material warehouse is not empty; Notify the inspection team to inspect the site, and ensure that the front and rear auxiliary machines are functioning properly. Once checked, it can be turned on, and the startup sequence should be clear; Follow the logistics in the opposite direction, and start the auxiliary machine after grinding first; After grinding, the auxiliary machine is normal, and then start the vertical grinding of the main machine; How to start the grinder, first turn on the oil pump; First low pressure, then high pressure, and then open the sealing fan; Ten minutes later, the wind turbine will be turned on again after surpassing the clutch; Assist the motor to transition, then turn on the main motor; Keep up with the fast transportation of raw materials to prevent the danger of insufficient air grinding; Observe the startup normally and monitor the data carefully; Keep various parameters in mind, compare and analyze them in a regular manner; Be calm in the face of things, there is no need to panic. Only by dealing with things calmly can we handle them properly; The shutdown sequence is exactly the opposite, following the logistics to the end; Don't worry if the host stops, the oil pump will stop slowly for three to five minutes; After the circulating fan stops, the seal stops after ten minutes; Cut off the power and water sources, make a record of cleaning completion.

　　How about it? After reading the seven character proverb above, do you feel relaxed? From the structure of the vertical grinder to the operation method, it can be easily mastered with just a simple memory.
