Abstract
PURPOSE: To prevent the fluctuation of the particle size distribution of powdered coke, by sampling the powdered coke crushed with a rod mill continuously, measuring the particle size of the sample, and controlling the rotational speed of the rod mill to adjust the measured size to the target value.
CONSTITUTION: Powdered coke in the tank 1 is fed to the sieve 3 through the belt feeder 2 and the belt conveyor 7-1, and e.g. separated into the coarse fraction having the particle size of ≥5mm and the fine fraction having the particle size of ≤5mm. The coarse fraction is fed to the rod mill 4 through the conveyor 7-2, crushed, and fed to the sieve 6 through the conveyors 7-3 and 7-4. In the course of the transfer, a part of the powdered coke is sampled with a belt sampler 5, and dropped to the conveyor 7-4. The falling powdered coke is watched with a high- speed TV camera 8, and the signal from the camera is transmitted to the particle- size detector 9. The data analyzed in the detector 9 is inputted into the arithmetic unit 10, which compares the data with the preset target value, and controls the rotational speed of the rod mill 4.
