Description

Technical Field

[0001] The utility model belongs to the technical field of powder material feeding, and in particular relates to a powder material feeding device. Background Art

[0002] Cement: a powdery hydraulic inorganic cementitious material, which becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly bond materials such as sand and stone together. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been widely used in civil construction, water conservancy, national defense and other projects as an important cementitious material. A feeding device is needed in the processing of cement powder to perform metering and feeding processing. However, due to the small bulk density and good self-flowing property of cement powder, it is very easy to cause material impaction and dust, which makes it difficult to control the feeding flow rate, and it is easy to feed too much or too little. Too much feeding is easy to cause blockage and poor feeding, while too little feeding leads to uneven feeding, which leads to unstable and inaccurate metering, causing great hidden dangers to the quality of cement products.
