Rotary kiln basically is used at iron ore of deficient of factory of metallurgy industry iron and steel to magnetize roast, roast of oxidation of mine of chromic, ferronickel, wide application is won in the industry such as building materials, metallurgy, chemical industry. Of rotary kiln it is normal to its to jam locomotive production can produce serious effect, SBM machine brings a few small doohickey that prevent rotary kiln to jam for everybody.
1. opens examination of the system before kiln
After overhaul of system of intake air heater ends, must have serious and careful comprehensive examination to the system, will clear clean inside each conduit. Liner of examination intake air heater is firm. Before opening pit, the examination that pursue course discharges grey a powerful person, whether does roll have neatly die without card or damage.
2. system is sealed
The place such as each aperture of will all inspection door, flange, side, grey valve shaft answers to close before opening pit tight, the air leak outside preventing. After processing jams, cannot pursue save trouble and those who ignore inspection door is sealed. Answer to use firebrick to be sealed dead inside the door first when inspection door is sealed, shut inspection door to use next fresh water glass of raw material mix into seals all crack severe.
3. stable operation, strengthen responsibility heart
The temperature after attending a meeting kiln every time rises gradually, should casting makings around period of time is diligent the activity discharges grey a powerful person everywhere, device of actuate hair drier in case canopy makings. When normal production, should mix strictly according to each regulations system operating rules operation, maintain temperature pressure reasonable distributing; Add decrease makings should seasonable, wind, coal, makings wants reasonable cooperate, feed makings quantity and kiln fast want synchronism. When because short or other reason are forced to decrease,expecting, platoon wind is not decreased substantially come down, because use wind,prevent small and form indigestion makings. Requirement post class wants diligent observe connection, frequently examination, frequently, diligent activity.
4. improves the quality of raw material and fuel
Should make sure raw material and fuel part are stabilized equably, tie-in and reasonable. Adopt optimize burden, adjust clinker to lead a value, maintain fluid photograph quantity to be in 24 ～ 27% . Improving coal fines quality is to prevent coal fines to burn to create a measure that knot skin jams not completely, alleged improve coal fines quality, ask to reduce fineness to arrive namely 10% the left and right sides, reduce coal fines moisture to arrive 1.0% the left and right sides, avoid to use inferior coal and tall sulfur coal.
Do good above seriously when, SBM machine believes to be able to reduce a lot of troubles for you, save a large number of time, thereby better faster catch production, stimulative enterprise produces beneficial result.
