Background In the working process of the rotary furnace, materials and fuel enter from different ends of the kiln respectively, namely, the materials enter from the high-end kiln tail of the barrel body, and the fuel is sprayed from the kiln head. With the tilting and slow turning action of the cylinder, the material rolls in the circumferential direction and moves in the axial direction from the high end to the low end. After the material enters the rotary furnace, the material gradually moves from the kiln tail to the kiln head due to the fact that the cylinder rotates at a certain speed and has a certain inclination. Because the rotary furnace is huge in volume, the rotary furnace is limited in rotating speed, different materials are different in required rotating speed, the materials are dispersed in the furnace when the rotating speed is too high, the situation of a large maraca is caused, the materials are easy to accumulate in the furnace when the rotating speed is too low, and the situation of the small maraca is caused.
