Experimental furnace kiln speed size affects the size of the kiln feed rate, in short, the experimental furnace quick kiln and kiln feed rate is proportional to the relationship, the high temperature furnace so specifically, experimental furnace kiln speed affects the kiln feed rate.
The experimental furnace kiln speed gradually with the increase of feed rate of speed up. When the system is running normally, kiln speed should be controlled in general 3.0 r/min, but has a tendency to increase again in recent years, the highest reached 4.0 r/min, this is one of the important features of precalcining kiln.
Experiment of electric furnaces faster, furnace material thin layer, raw material with good heat exchange between hot gas, tubular electric furnace material is heated evenly, presintering well into the calcining zone of the material. But the beat circle, kiln or small collapse, a slight change of furnace thermal system, add a bit of feed coal, system will be able to return to normal soon.
Experimental furnace and kiln kiln speed feed rate of containment and influence the experimental furnace users friends can pay attention to, should according to own situation, correctly grasping the box-type furnace kiln speed, vacuum furnace atmosphere better operating and control our experiment furnace equipment.
If kiln speed too slow, preservation.the layer is thick, the material and heat tube furnace body heat exchange, presintering, raw shadow will approximation kiln head, a slight change of furnace thermal system, easy to run raw.
Then increase the feed coal, electric box furnace material layer thickness due to the stove, the temperature in the firing is very slow, it's easy to have a short flame forced to burn, producing yellow heart, clinker fCaO is high also, and at the same time a large number of not burning coal powder fell into the bed caused by incomplete combustion, also easy to occur in the rotary kiln big eggs or ring.
