Description

Technical Field

[0001] The utility model relates to the technical field of integrated crushing machines, in particular to an integrated feeding and crushing machine for coal gangue. Background Art

[0002] Gangue is solid waste generated during coal mining and washing. It contains certain elements such as carbon and sulfur and has certain utilization value. With the improvement of environmental awareness and the advancement of comprehensive utilization of coal resources, the utilization value of gangue has gradually been paid attention to. In order to achieve the purpose of recycling and processing gangue and converting it into valuable resources, such as using gangue for brick making, it is usually necessary to crush the gangue and perform other processing operations to break larger particles of gangue into smaller particles. When performing crushing operations, a corresponding integrated crusher is usually required.

[0003] There are many types of integrated crushers on the market. Since the integrated crusher has a certain height, in order to facilitate the loading, a corresponding loading mechanism is usually installed on the integrated crusher. Common loading mechanisms include scraper conveyors, which are used to realize loading operations.

[0004] However, most integrated feeding and crushing machines lack corresponding dust treatment components on the top when in use, and cannot achieve dust treatment operations. Since dust is generated during the crushing process, the dust will pollute the surrounding environment. Some integrated feeding and crushing machines use spraying to complete dust removal operations, but spraying dust removal requires more water, resulting in a waste of water resources. In view of this, we proposed an integrated feeding and crushing machine for coal gangue. Utility Model Content
