Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a raw material feeding device. Background Art

[0002] Cement raw materials are made of lime raw materials, clay raw materials and a small amount of correction raw materials. Sometimes mineralizers, crystal seeds, etc. are added. Coal is also added in proportion during vertical kiln production. The materials ground to a certain fineness are called cement raw materials. Their chemical composition varies with the type of cement, the quality of raw materials and fuel, the production method, the type of kiln and other production conditions. Raw materials have the form of raw material slurry, raw material powder, raw material balls and raw material blocks depending on the cement production method. They are respectively suitable for the requirements of wet, dry, semi-dry and semi-wet production. Regardless of the form of raw materials, they are required to have stable chemical composition, fineness and moisture to meet the requirements of different production methods, so as not to affect the calcination of the kiln and the quality of clinker. In the process of cement production, a conveying device is needed to transport the cement raw materials to the cement raw material roller press equipment.

[0003] When the existing raw meal feeding device is feeding, some agglomerated raw meal will be mixed in the raw meal, which can easily cause feeding blockage, thereby leading to uneven feeding of the cement kiln, making it difficult for the material to flow out smoothly and the feeding stability is poor. Therefore, those skilled in the art provide a raw meal feeding device to solve the problems raised in the above background technology. Utility Model Content
