Synthetic rutile kiln rotary kiln carbon sticky bulk of the causes Detailed 0371-63650088 
 Also known as shifting sand sticky bulk material is calcined in rotary kiln rather special phenomenon, causes complex, great impact, fix red-hot kilns have the risk of a serious threat to safety. Produce sticky bulk material as long flame concentration of liquid-phase can not appear in the firing zone, the material is not easy to adhere to the original rotary kiln cured skin, contrary to the kiln at high temperatures, thin skin erosion, combined with first met when this lack of experience, burn-liter heavy force, burning the lining large, so quickly ablation occurred red kiln. 
 Rotary sticky bulk production, mainly in the rotary kiln under high temperature end, the material preheat over into the firing zone particularly vulnerable after the burn, there is no reasonable argument to adapt the control characteristics of the material, but still the normal way calcined, coal-relatively big wind, burned too far; or when the material thickness, not to pre-attack and slow method, but braved the wind to increase the coal burned, burned bright stick. Thick-skinned as the first kiln, the material point in time by fire, scattered sticky feeling less serious phenomenon, little change in skin of the kiln, the operator is not very attention. With the shifting sand material production, end grain is not good, burning zone temperature increased, tail temperature also increased accordingly. With time, the kiln gradually thinning skin, gradually long before the ring is high, the material in the rotary kiln residence time increased, prompting fCaO less sticky powder prominent. Petrographic observations that the sticky material in bulk is due to enter the firing zone, the intense heat, resulting in a large number of inclusions of A concealed mineral raw crack, break even, while the inclusions escape, with its original package A rapidly from the mine and adjacent part of the original structure, resulting in end grain surfaces of clinker powder, into shifting sand, the original structure into a porous loose. 
 Prone to the following sticky bulk materials: 
 1 clinker in the high alumina content, low silicate, rotary kiln speed benchmark slow, pull the wind is too large, the higher end of temperature control. 
 2 clinker minerals in the molten medium low, and EH, n is higher. 
 3 rotary kiln skin concave, the first circle of high or excessive burning of coal tube inserted into the ring post.
