Production process of alpha-alumina micro powder for microcrystalline high-alumina ballstone and lining bricks
The invention discloses a production process of alpha-alumina micro powder for microcrystalline high-alumina ballstone and lining bricks. A cyclone preheater is vertically arranged and is fixedly arranged on a plurality of brackets; an outlet end of a feed hopper is connected with a rotating dryer; one end of the rotating dryer is connected with an additive adding pipe; the other end of the rotating dryer is connected with a grinder; an outlet end of the grinder is connected with a preheating chamber; the bottom of the preheating chamber is connected with an elevator; the upper end of the elevator is connected with a cyclone preheater; the lower end of the cyclone preheater is connected with a calcining kiln; one end of the calcining kiln is connected with a drum-type cooling machine; a hot air pipe is connected to the side wall of the drum-type cooling machine; and the tail end of the hot air pipe is connected with the preheating chamber. The obtained product not only can be used forglaze, but also can be used in the whole process of ceramic production, the application range is wide, the conversion rate of alpha-alumina obtained in production is high, the wear resistance of theproduced ceramic product is good, and the whole process can be used for continuous production.
本发明公开了一种微晶高铝球石和衬砖用α‑氧化铝微粉生产工艺，所述旋风预热器竖直设置，且旋风预热器固定设置在若干根支架上；进料斗出口端连接回转式烘干机，回转式烘干机一端上部连接添加剂添加管，回转式烘干机另一端连接研磨机，研磨机的出料口端连接有预加热室，预加热室底部连接提升机，提升机上端连接旋风预热器，旋风预热器下端连接煅烧窑，煅烧窑一端连接滚筒式冷却机，滚筒式冷却机侧壁上连接有热气管，热气管末端连接预加热室。得到的产品不仅可以用于釉料，还可以用于陶瓷生产的整个过程中，适用范围广，且生产中得到的α‑氧化铝转化率高，生产的陶瓷产品耐磨度好，且整个工艺可以连续生产。
