The element that causes system of rotary kiln of new-style cement working a way to written guarantee the skin jams is very much and complex, accordingly from craft, former light system of material, equipment, hot industry, operation and management to go up serious and careful analysis research. According to the manufacturing experience of company of a few cement, the main reason that causes knot skin to jam has the following sides roughly:
1. writtens guarantee the skin is caused jam
Knot skin is high temperature stock is in smoke room, ascendant conduit, various (basically be 3, 4 class) of the felt on wall of tornado canister cone one layer upon layer and crustaceous, serious place shows circularity to shrink mouth. Block up of stock move normally, felt and burn frit alternant, make cerebral cortex amount and ply increase gradually, affect the ventilated, changed the stock inside intake air heater and air current traversal speed inside kiln and way, bring about after jam. The main reason that creates this kind of appearance has 3: The influence; local high temperature that winds grey influence, harmful element causes knot skin to jam.
2. air leak causes jam
Air leak is the star of one big gram that kiln decomposes outside kiln, it reduces efficiency of tornado canister depart not only, raise hear rate, it is a when cause a system to jam main factor more. Air leak causes inside jam the air leak outside mixing causes jam.
3. operation is undeserved cause jam
(1) is cast makings is not seasonable.
(2) opens the platoon when stopping kiln wind force is undeserved.
(Quantity of the makings below 3) and kiln fast different situation.
(Control of 4) platoon wind force is undeserved.
(Wind force of 5) kiln, furnace allocates not all, the operation is not harmonious.
4. exotic causes jam
Inspection door brick of the system sets build by laying bricks or stones not fatigue breaks down fall; tornado canister, decompose furnace coping and liner material to flake the canister inside; tornado canister or spillage board burn out drop; discharges grey a powerful person to burn out or roll is ineffective the firebrick when; is overhauled or ironware.
5. design is undeserved, congenital inadequacy causes jam
Systematic design should create good condition for production, cannot design because of certain place unreasonable, cause congenital inadequacy, influence production. The system that congenital inadequacy creates jams, aborning is very unmanageable, avoid. Be like: The level joins conduit grows too, join conduit angle crosses small; aspect ratio of air inlet of various intake air heater slants the canister inside small; of angle of small; cone grows; to answer ash too cannot even mix into is entered wait to will affect production.
