摘　　要：本试验以膨润土和循环流化床飞灰为主要原料,添加黏结剂和改性剂,采用圆盘造粒法制备了循环流化床飞灰猫砂。结果表明,当飞灰质量分数为50%时,猫砂吸水率为225.98%,团聚质量为23.4 g,团聚长度为33.54 cm。循环流化床飞灰猫砂的吸水率和粉碎率均低于商品猫砂,且成团质量较差,但是仍满足企业标准,且降低了膨润土猫砂的生产成本,避免了飞灰的二次污染。为改善循环流化床飞灰猫砂的色泽,降低其含尘量,在循环床飞灰猫砂中添加增白剂和涂层剂,以提高消费者的接受度和市场竞争力。In this paper,using bentonite and circulating fluidized bed fly ash as main raw materials,adding binder and modifying reagent,the circulating fluidized bed fly ash cat litter was prepared by disk granulation.The results showed that when the mass ratio of fly ash was 50%,the water absorption rate was 225.98%,the mass of agglomeration was 23.4 g,and the length of agglomeration was 33.54 cm.Although the water absorption rate and pulverization rate of circulating fluidized bed fly ash cat litter were lower than that of commercial cat litter,and the clumping quality was poorer,it still meet the enterprise standard,reduced the production cost of bentonite cat litter,and avoided the secondary pollution of fly ash.In order to improve the color and reduce the dust content of circulating fluidized bed fly ash cat litter,brightening agent and coating reagent were added to improve consumer acceptance and market competitiveness.
