[0002] Shaft kiln raw meal granulation is an important link in the calcination operation of the shaft kiln. For a long time, the shaft kiln raw meal granulator of the shaft kiln enterprise mainly uses the ball forming disc to form balls, which uses the raw material to be naturally rolled into balls in the ball forming disc. , the amount of water added to the raw meal is relatively large, generally greater than 12%, and the particle size of the balls formed is different, and there are a small amount of powder and large balls, which leads to an increase in the heat consumption of the shaft kiln (because the water is large, the heat of vaporization required for water evaporation The ventilation resistance of the shaft kiln is uneven, the ventilation resistance of the shaft kiln increases, and it is impossible to operate with full wind, which affects the improvement of the production quality of the shaft kiln

Embodiment Construction

[0007] Referring to the accompanying drawings, the structure is that a filler device 4 is provided below the hopper 2, the filler device 4 is connected to the female mold 5, the female mold 5 is respectively connected to the mold ejection device 3, and the mold repair ring 6, and the stripping module 9 on the female mold 5 is located on the Above the vibrating screen 8, the female mold 5 is provided with a ball mold bottom pin, and the speed reducer 11 is respectively connected with the female mold 5, the mold ejection device 3, and the mold repair ring 6 through bearings.

[0008] work process

[0009] The hoist 1 installed on the side of the main machine sends the material into the hopper 2 under the control of the first motor, and the material enters the filling device 4 working under the control of the second motor through the hopper 2. Before that, the mold ejection device 3. The bottom pins of the ball mold on the mother mold 5 discharge the empty mold of the material ba...
