Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
The grinding capacity of the coal mill is gradually reduced at 10 s, and the raw coal stored in the mill is gradually increased (Fig. 7(e)). Since the conversion efficiency of raw coal to coal powder is reduced, the coal powder stored in the mill is decreased in the initial stage of simulation (Fig. 7(f)).
3. The hot air and raw coal enter the mill through feeding device. When the dry grinding mill operates, raw coal is raised, scattered, and dried by hot air. 4. Additionally, our windswept coal mill is designed with steel balls inside. Raw coal is crushed and ground by steel balls and the fine powder are exhausted with the hot air. 5.
