3 vertical grinder3.1 vertical grinder working principle block diagram
vertical grinder working principle block diagram see Figure 1Figure 1 shows that every part of the system fails to affect the normal operation of the systemEvery small detail user should attach great importance to, timely exclusion, in order to ensure the stable and reliable work of the systemdepending on how the grinder works, what are the consequences of a failure of a part of the system during normal operation? First of all, the values of the three variables are constant, i.eoutput, feeding speed, and lead volume are constant:(1)dust cabinet leakage, working air volume↙, cyclone separation efficiency ↙, yield ↙, due to the constant feeding speed,the material in the main grinding cavity ↗, main grinding temperature ↗, main grinding motor current ↗, sub-grinding motor↗ current, if the long-term work or summer room temperature is higher, the secondary grinding or cooling phenomenon will occur(2)dust bag powder excessive breathability difference, working air volume↙, cyclone separation efficiency ↙, yield ↙, due to the feeding speed is unchanged, the main grinding cavity material ↗, the main grinding motor current ↗, the main grinding temperature ↗ , long-term work will occur sub-grinding shutdown or main grinding cavity curing phenomenon(3)the top cap cap plate of the cyclone separator leaked the wind, the working air volume ↙, the cyclone separation efficiency ↙, the ultra-fine powder ↗, the output ↙, the main grinding motor current ↗, the main grinding temperature ↗(4)discharge air leakage, working air volume ↙, cyclone separation efficiency↙ ultrafine powder ↗, output ↙
3.2 important notes
the main grinding steering according to the direction of the signIt is strictly forbidden to clean the main and secondary grinding with waterdust bag to be washed regularly with water, to maintain permeabilitythe first task before each shift is to open the oil-water separator and air compressor sewage valve, drain the oil and waterclose, and then start workSummer generally 2 to 4 times per class, winter generally 1 to 2 times3.3 clearance method(1) self-cleaning method: open the fan, move out of the cyclone sieve, with pure high-pressure air source clean need to clean the part(2) the use of high-power hotel vacuum cleaners, pipeline and other parts of the clean-up3.4 pulsed gas source configuration requirements
(1) the best choice of oil-free or semi-oil-free air compressor, oil lubrication can alsoThe exhaust volume is 0.6 to 0.9m3/min operating pressure 7cm2/kg
(2) must be equipped with oil-water separator device, the gas source by oil and water separation, in order to pass into the dust collector its specifications are: 1 to 2m3/min
(3) summer production, the drainage water valve at the bottom of the air compressor cylinder every shift to open, the storage cylinder memory water and water removal
