Abstract: The resources of oil shale is extremely rich in Huadian city and Nongan county, Jilin Province. The authors preliminarily introduced a new technique to produce ultra light ceramisite with the oil shale dregs as main raw material in Shifan Electricity Plant with a new experimental equipment developed by ourselves. This equipment can produce normal ceramisite with the similar quality as the products of the rotary kiln. In addition, small ceramic slag can be produced. The working efficiency is promoted by several dozens times than existing burnexpand experiment method but the labor intensity significantly decreases. A ceramisite factory crafts with annual productivity of 200 000 cubic meters using domestic ceramisite production equipment were designed here. The surplus heat of the rotary kiln two extremities were reused in a feasible way.The content of SiO₂, Al₂O₃, R₂O in oil shale are moderate and the content of C is very low. The ceramisite density can be controlled by adjusting the quantity of the froth agent. Ceramisite & ceramic slag range with density from 300 kg/m³ to 500 kg/m³ can be produced at the temperature ranging from 1 030℃ to 1 100℃.

Key words: oil shale dregs, ultra light ceramisite, burnexpand experiment, craft plan, utilizing surplus heat
