Description

Technical Field

[0001] This utility model relates to the field of cement pulverized coal technology, and in particular to a pulverized coal ash cement feeding device for a production line. Background Technology

[0002] Fly ash cement, also known as fly ash silicate cement, is a hydraulic cementitious material made by grinding silicate cement clinker, fly ash, and an appropriate amount of gypsum. Fly ash cement has many excellent properties, with a compact structure and low water absorption capacity. It is suitable for projects with certain requirements for corrosion and erosion resistance.

[0003] The fly ash cement feeding device is a cement production and material feeding equipment. Existing cement feeding devices usually feed cement ash directly through the silo and discharge pipe. However, the fine particles of fly ash cement have poor fluidity and are prone to bridging due to friction in the silo and discharge pipe, leading to feeding interruptions. At the same time, the material is prone to stratification or segregation due to factors such as the stacking angle and uneven humidity, resulting in fluctuations in the feeding speed and affecting feeding efficiency. In addition, a large amount of dust and impurities are generated during cement feeding. Dust entering bearings, gears and other parts will accelerate mechanical wear, shorten the equipment life, and the dust emitted into the atmosphere will harm the regional environmental quality.
