Preparation method of lightweight ceramsite
The invention discloses a preparation method of lightweight ceramsite, and belongs to the technical field of ceramsite processing, fly ash is used as an inner core, a pulverized material is used as a shell, double-layer ceramsite green pellets are prepared, preheating and roasting are performed, natural cooling is performed, the powdery shell is screened out after cooling, and a ceramsite finished product is formed. According to the method, the roasting temperature is increased through the pulverization material shell with the melting point being 1300 DEG C or above, then the roasting time is shortened, the production efficiency is improved, and meanwhile the high-strength light ceramsite with the low water absorption rate and the high surface roughness is obtained.
本发明公开了一种轻质陶粒的制备方法，属于陶粒加工技术领域，以粉煤灰为内核，以粉化料为外壳，制备双层陶粒生球，预热和焙烧后自然冷却，冷却后筛除粉末状外壳形成陶粒成品。本发明通过熔点在1300℃以上的粉化料外壳提高焙烧的温度，进而缩短焙烧时间，提高生产效率，同时得到吸水率低、表面粗糙度高的高强度轻质陶粒。
