The device used in the plant is selected from coal gangue, coal materials, and preliminary dewatering cycle, and the role of both the transport and the height compensation device configuration. Usually, the receiving box is connected to the washing machine, and sometimes it can be placed in the pyramid concentration tank. The water-containing material is loaded with a dewatering bucket, and the water is self-extracted from the bucket during the lifting and transportation process. The equipment can be used as the final dewatering equipment for coarse material with low density (specific gravity); for fine material, it is generally used as preliminary dewatering. In order to adapt to the dewatering operation, the installation angle of the hoist is generally 50 ° ~ 70 °. The two buckets should be separated by a traction chain. Practice has shown that the lifting height of the dewatering hoist should be at least 4 meters above the water level, 5 to 7 meters for coarse materials, and 6 to 8 meters for fine materials to ensure sufficient dewatering time. According to the granularity of the material to be transported, the speed of the bucket movement is 0.25 to 0.270 m/sec and 0.15 to 0.17 m/sec, respectively. The dewatering effect of the dewatering bucket hoist is related to the particle size and properties of the material. The structure of the dewatering hoist is shown in the figure below. The production capacity of the dewatering bucket hoist when transporting dry materials is: Where Q———the production capacity of the dewatering hoist, t/h;

I—the volume of each bucket, L;
υ———The speed of the bucket movement, m/s;
a———the pitch of the drag chain of the bucket, m;
Ï———the bulk density of the material, t/m 3 ;
————The filling rate of the bucket is generally 0.5~0.75 when calculating the traffic; when calculating the power, it is generally 0.9 (considering the control and fluctuation).
The specific selection specifications and motor power of the dewatering bucket hoist should be combined with the object of use, and the combination of the equipment samples can be calculated one by one.
