Low-thermal-conductivity mullite brick for rotary kiln and preparation method of low-thermal-conductivity mullite brick
The invention relates to the technical field of hot mullite brick processing, and discloses a low-thermal-conductivity mullite brick for a rotary kiln and a preparation method thereof.The preparation method comprises the steps that raw materials including 10-15 parts of mullite, 3-6 parts of special aluminum oxide and 5-10 parts of kaolin are prepared, coarse crushing is conducted through a crusher, one part of the raw materials enter the crusher to be crushed and screened, and the other part of the raw materials enter the crusher to be crushed and screened; the raw materials enter different stock bins after being screened, the raw materials with the particle size larger than 3 mm return to a crusher to be crushed, the other part of the raw materials enter a barrel mill to be processed into fine powder with the particle size smaller than or equal to 0.088 mm, the fine powder enters the stock bins, and sulfurous acid paper pulp waste liquid serves as a binding agent. Filtered air is jetted to semi-finished green bricks through the air jetting component, so that the interior of the dryer is kept at proper humidity, the dryer cannot rapidly suck away moisture of the semi-finished green bricks, the semi-finished green bricks are gradually and integrally dried slowly through continuous back-and-forth sucking and spraying, surface cracking is avoided, and the quality of the semi-finished green bricks is improved. And the internal wet and soft condition is avoided.
本发明涉及热莫来石砖加工技术领域，且公开了一种回转窑用低导热莫来石砖及其制备方法，制备方法包括准备原料，其中原料包括莫来石10‑15份、特种氧化铝3‑6份和高岭土5‑10份,通过破碎机进行粗碎，一部分进入破碎机进行破碎筛分，经过筛分后进入到不同的料仓，将粒度＞3mm的原料重新回到破碎机破碎，另一部分进入筒磨机加工成≤0.088mm的细粉料进入料仓,通过采用亚硫酸纸浆废液作为结合剂。本发明通过喷气部件将过滤的空气喷射至半成品砖坯上，以此让干燥器的内部保持合适的湿度，让干燥器不会快速的抽走半成品砖坯的湿气，而是通过不断的来回抽取与喷洒，逐渐让半成品砖坯整体缓慢干燥，不会出现外表开裂，内部湿软情况的发生。
