Description

Technical Field

[0001] The utility model relates to the technical field of mineral powder feeding, in particular to an ultra-fine mineral powder feeding and adding device. Background Art

[0002] Ultrafine mineral powder is the most widely used building material in the construction industry. Its main purpose is to improve the pore structure and cement stone aggregate interface structure, which can effectively improve the performance and practicality of concrete. Ultrafine mineral powder generally includes silica fume, ultrafine slag, ultrafine fly ash, ultrafine zeolite powder and ultrafine limestone powder, as well as different combinations of the above ultrafine powders. In the process of processing and making ultrafine mineral powder, various chemical materials are often mixed together. In the process of processing ultrafine mineral powder, because of its low density and large overall mass, it is often necessary to use a feeding device to complete the feeding work.

[0003] Among the existing feeding devices for ultrafine mineral powder, most of them can only complete a single feeding function. Due to the complexity of the substances contained in the ultrafine mineral powder, there is generally a mixing device to mix the various substances contained in the ultrafine mineral powder before continuing to the next stage of processing. In this case, the ultrafine mineral powder needs to be stirred in the stirring device and then discharged to the place where it needs to be processed. Such a processing method for ultrafine mineral powder is likely to lead to a situation where the ultrafine mineral powder is in short supply when there is a large demand for ultrafine mineral powder.

[0004] In this regard, a feeding and adding device is proposed which can mix the ultrafine mineral powder during the feeding process of the ultrafine mineral powder, which can not only effectively save time, but also effectively save a part of the processing cost. Utility Model Content
