摘　　要：以钾长石和石灰石为原料,利用模拟水泥熟料生产的预热器窑进行了硅钙钾肥的半工业煅烧实验,对煅烧后硅钙钾肥的有效营养元素含量和矿物成分进行了分析。结果表明,采用带预热器的回转窑系统(预热器窑)生产硅钙钾肥是可行的,实验室石灰石分解后再参与煅烧,不会对最终土壤调理剂的性能产生不利影响。提出了预分解窑煅烧硅钙钾肥土壤调理剂生产线的烧成工艺设计方案。Using K-feldspar and limestone as raw materials, Si-Ca-K fertilizer is produced by semi-industrialization sintering in the preheater kiln platform, which is simulated the cement clinker production. The contents of available nutrient elements and mineral composition of this fertilizer after sintering are analyzed. The results indicates： the feasibility of using rotary kiln with preheater （preheater kiln） to produce Si-Ca-K fertilizer is feasible; Using calcined limestone to produce Si-Ca-K fertilizer in the experiments has no negative effects on the properties of ultimate product. The pyroprocessing design scheme of precalcining kiln is put forward for the production line of Si-Ca-K fertilizer soil conditioner.
