Coating Approach to Prevent Agglomeration of Spherical Lightweight Aggregate (LWA) During Sintering
During lightweight aggregate (LWA) production through sintering process, formation of liquid phase captures emitted gas to form pores in the LWA and leads to successful bloating. As the LWA undergoes sintering in the kiln, the liquid phase starts to form on the LWA surface. Accordingly, in a rotary kiln where the LWA are continually rolling over each other, the touching surfaces of LWAs with liquid phase start to adhere together and form lumps of LWA exiting the furnace. This method prevents agglomeration of spherical LWA during sintering. The LWA can be produced from clay, slate, shale, and potentially other waste materials. This method results in production of discrete spherical LWA particles that can be coated with waste fly ash particles to form a thin layer on the surface of LWA that will not melt during sintering and will prevent touching surfaces of LWA particles from sticking together and forming lumps.
