Description

Technical Field

[0001] The utility model relates to the technical field of limestone crushing, and more specifically, it relates to a limestone crushing device for building cement production. Background Technique

[0002] Cement is a powdery hydraulic inorganic binder. After being mixed with water and stirred, it becomes a slurry, which can harden in the air or in water and can firmly bond materials such as sand and stones together. Cement is mainly made of limestone and clay. After being crushed, proportioned, and ground into raw materials, it is then fed into a cement kiln for calcination into clinker, and then the clinker is ground with an appropriate amount of gypsum (sometimes mixed materials or additives are also added). During the production process of cement, large pieces of limestone need to be crushed into granular form, then the limestone is ground into powder, and finally various powdery aggregates are evenly mixed.

[0003] However, the existing limestone crushing equipment has the problem of uneven crushing after crushing. Usually, a filter screen is used to filter it, so that the unqualified limestone is crushed again. However, the existing crushing equipment is not convenient to automatically convey the unqualified limestone into the crushing equipment for crushing, and it is inconvenient to use.
