Description

Technical Field

[0001] The utility model relates to the technical field of grinding mills, in particular to a fly ash grinding mill capable of avoiding accumulation. Background Art

[0002] The main sources of fly ash are coal-fired power plants and urban central heating boilers, of which more than 90% is wet ash, which is less active than dry ash, and wastes water and electricity, pollutes the environment, and is not conducive to comprehensive utilization. In order to save energy and protect the environment and recycle waste, fly ash is often used in the construction industry as a raw material for concrete or made into bricks. Research and engineering practice have shown that the effect of fly ash on water and concrete is closely related to its fineness. The finer the fineness, the better the effect.

[0003] Announcement No. CN 219441806 U discloses a fly ash mill, which can effectively grind fly ash waste through the grinding device in the grinding box. Compared with the traditional fly ash mill, it not only reduces the production cost, but also has a simple internal structure, which is conducive to the user's cleaning of the mill, further reducing the processing waste of fly ash. The feed inlet is arranged inside the grinding box, further limiting the path of fly ash entering the grinding box, reducing the amount of fly ash at the corners of the grinding machine, and better grinding all fly ash, so that the ground fly ash is more uniform, which is conducive to improving the grinding effect. However, the patent still has the following problems in actual use:

[0004] Although the fly ash mill grinds the fly ash by means of a grinding device, no relevant screening device is provided to screen the ground fly ash. Some insufficiently ground fly ash will be produced during the grinding process, which requires subsequent screening for sorting, which not only wastes time but also increases the number of steps and the cost of grinding. No relevant anti-clogging structure is provided at the discharge port to prevent the fly ash from being blocked, thereby affecting the discharge speed of the discharge port.

[0005] A fly ash grinding machine for avoiding accumulation is proposed in order to solve the above-mentioned problems. Utility Model Content
