[0015] Now in conjunction with accompanying drawing, the present invention will be further described.
[0016] Such as figure 1 As shown, the method for making unfired ceramsite from this phosphogypsum is as follows: after drying the phosphogypsum with a water content of 20%-30%, it is sieved or crushed to form a powder, and the phosphogypsum powder and cement are measured and mixed evenly After that, it is transported to the pelletizing disk by the conveyor, and the pelletizing disk rotates clockwise. The phosphogypsum powder and cement move in the opposite direction relative to the pelletizing disk under the action of the scraper machine of the pelletizing disk, and simultaneously with the rotation of the pelletizing disk. Spray water mist, make phosphogypsum powder and cement into balls, and transport them to Pingku through a belt conveyor to stack for natural curing for 72-120 hours, and then make unfired ceramsite products. In the above method, the ratio of phosphogypsum...
