Novel mullite formula
The invention relates to a novel mullite formula which comprises the following raw materials in parts by weight: 50% of alpha Al2O3, 45% of coal gangue and 5% of dolomite. The process flow is as follows: burdening the three raw materials through an electronic belt scale, feeding into a grinding head bin, and crushing into 325-mesh powder through a vertical mill; adding water to 7%-9%; feeding themixture into a primary double-shaft stirrer and then feeding the mixture into an aging bin; adding water to 14%-16%, and feeding the mixture into a secondary double-shaft stirrer; sequentially feedingthe mixture into a strong stirrer, a bipolar vacuum extruder and a slitting and blank cutting machine; loading the formed object by a robot; and drying the formed product, calcining the formed product at 1600 DEG C, and crushing and packaging the product . The preparation method has the beneficial effects that a complete crystal structure is obtained by proportioning coal gangue and alpha Al2O3,no cristobalite exists in the internal structure of the product, and 5% dolomite is added to increase the mullite content and form a small amount of magnesium aluminate spinel.
本发明涉及一种新型莫来石配方，包括以下重量份的原料：阿尔法Al2O3：50％,煤矸石：45％，白云石：5％。其工艺流程为：将上述三种原料通过电子皮带秤配料入磨头仓‑立式磨粉碎成325目‑加水7％‑9％入一次双轴搅拌‑陈化仓‑‑加水14％‑16％‑入二次双轴搅拌机‑强力搅拌机‑双极真空挤出机‑切条切坯机‑机器人装车‑干燥‑1600度煅烧‑破碎‑包装。本发明的有益效果为：通过煤矸石与阿尔法Al2O3配比，取得完全的晶体结构，保证了产品内部结构没有方石英存在，加5％白云石增加莫来石项和形成少许镁铝尖晶石。
