Use realistic rotary pace, strengthen the Vertical Roller Mill degree of hammer fastly while in the early stages, improve grate framework to produce absolutely free of discharge; adjust the interval in between each and every components, and ensure the interval is inside the right variety, each of the above methods performed to reduce the wear of hammer. Through the analysis with the aspects influence the impact crusher wearable hammer, aims at unique influence elements, the different minimize wear measure need to be taken, which to prolong the support life of hammer head, reduce the supplies consumption and downtime, attain the target that lessen investment and boost enterprises economic benefit.
Aboard hammer and liner plate of Vertical Roller Mill are simple to put on, which want routine maintenance. At present, the aboard hammer and liner plate in our country mainly created from higher manganese steel. For the distinction of heat treating supplies, its services existence is distinct. Our country also designed a type of impact hammer produced from Minimal alloy white cast iron or substantial chromium iron, which has the options of large hardness, superior abrasive resistance, straightforward production, minimal investment, and has attain a fantastic result.
From the carbon steel aboard hammer, some producer use “up weld 64” and “up weld 64A” welding rod to surfacing a layer, or use High-manganese steel electrode to surfacing within the High-manganese steel electrode, these approaches can cut down dress in, and repair old aboard hammer or impact plate. The shape and fix approaches of aboard hammer is important to maintenance. The shape of aboard hammer needs to be convenient to dismounting, and make improvements to the metal utilization ratio. The weight of aboard hammer ought to be exact, and its error need to not be exceeding 0.5kg that for making confident the stable of machine. During Rotor static balance test, rotor ought to not rotate 1/10 circle when it stop in any point.
