Quantitative coal feeder mainly plays a great role in the production of coal, which is an essential measuring equipment in the pulverized coal production line. The raw coal in the coal storage yard enters the raw coal buffer bin in the production workshop through the underground transfer bin and the quantitative coal feeder and the raw coal belt conveyor.
Quantitative coal feeder product real picture
The original coal bunker is provided with a vibrator, and the lower part of the bunker is provided with a rod valve and a quantitative coal feeder, which is stably transported to the vertical mill feed port through the quantitative coal feeder.
The hot air inlet from the hot blast stove enters the vertical mill, the raw coal enters the vertical mill through the original coal bunker, and the hot air from the hot blast stove enters the vertical mill through the air inlet. When it passes through the mill roll area on the mill, it is rolled by the mill roll and the bulk material is directly crushed. The fine material is extruded to form a bed for intergranular crushing.
The material continues to move to the edge until it is carried away by the airflow, while the larger granular material falls back to the grinding tray and continues to be crushed. When the material in the air flow passes through the upper separator, through the blade, the coarse particles return to the mill for grinding, and the qualified fine powder is grinded along with the air flow.
