Example Embodiment
[0015] Example 1
[0016] Weigh 85kg of 80-mesh shell powder and 15kg of 80-mesh weathered coal, and mix them well.
[0017] First, transfer 50kg of the mixture to a disc granulator for granulation. The speed of the granulator is controlled at 30-45r / min, and water is sprayed intermittently. With the remaining material, the nuclei gradually grow up, and finally reach the desired particle (between 1.0-3.5mm); the control time of the granulation process is 15-25min. The granulated granular materials are directly sun-dried or transported to a dryer at 80-100°C for drying, so that the moisture content is not higher than 2.5%. Then the dried material is sieved through the screen, and finally the particle size of the finished product is controlled between 1.0-3.5mm, and the finished product rate can generally reach 80-85%. The unqualified products are crushed by the crusher and then re-granulated.
Example Embodiment
[0018] Example 2
[0019] Weigh 80kg of 80-mesh shell powder and 20kg of 80-mesh weathered coal, and mix the two well.
[0020] First, 40kg of the mixed material was transported to the disc granulator for granulation. The speed of the granulator was controlled at 30-45r / min, and water was sprayed intermittently. The remaining material makes the ball core grow gradually, and finally reaches the desired particle (between 1.0-3.5mm). The granulation process control time is 15-25min. The granulated granular materials are directly sun-dried or transported to a dryer at 80-100°C for drying, so that the moisture content is not higher than 2.5%. Then the dried material is sieved through the screen, and finally the particle size of the finished product is controlled between 1.0-3.5mm, and the finished product rate can generally reach 80-85%. The unqualified products are crushed by the crusher and then re-granulated.
Example Embodiment
[0021] Example 3
[0022] Weigh 82kg of 80-mesh shell powder and 18kg of 80-mesh weathered coal, and mix them well.
[0023] First, 60kg of the mixed material was transported to the disc granulator for granulation. The speed of the granulator was controlled at 30-45r / min, and water was sprayed intermittently. The remaining material makes the ball core grow gradually, and finally reaches the desired particle (between 1.0-3.5mm). The granulation process control time is 15-25min. The granulated granular materials are directly sun-dried or transported to a dryer at 80-100°C for drying, so that the moisture content is not higher than 2.5%. Then the dried material is sieved through the screen, and finally the particle size of the finished product is controlled between 1.0-3.5mm, and the finished product rate can generally reach 80-85%. The unqualified products are crushed by the crusher and then re-granulated.
