Abstract

The invention discloses a dispersion mill for preparing nanometer material modified cement. A cabin body is separated into a mixing and grinding cabin and a material collecting cabin by a grid plate;the lateral upper part of the mixing and grinding cabin is provided with two feeding openings; a stirrer is arranged in the mixing and grinding cabin; a plurality of metal blocks are arranged in the mixing and grinding cabin; the lower half part of the material collecting cabin is a funnel; the bottom of the funnel is provided with a discharging opening. The mixing and grinding cabin can effectively realize the simultaneous mixing and grinding of nanometer materials and cement; the nanometer ore powder agglomeration is broken; the sufficient and uniform mixing of nanometer particles and otherpowder can be realized. In the use process, a discharging opening at the lower part of the material collecting cabin is connected with a concrete stirring machine; a certain mass of composite materials are regularly discharged according to the concrete mixing ratio and the stirring machine process parameters; meanwhile, through the feeding opening of the mixing and grinding cabin, nanometer materials and cement are respectively and regularly added according to the production requirement proportion, so that the continuous production operation with the concrete stirring machine can be realized.

Description

technical field [0001] The invention relates to equipment for preparing nano-modified cement, in particular to a dispersing mill for preparing nano-material modified cement, which belongs to the technical field of cement and concrete materials. Background technique [0002] Improving the performance of cement concrete is the focus of research on cement-based concrete materials in the 21st century, and the modification of cement concrete with ultrafine minerals is one of the main ways for the evolution of concrete materials. Especially with the deepening of nanotechnology research and application fields, the research on the application of ultrafine mineral powders in cement-based materials is also in the ascendant stage in various countries around the world. The use of ultra-fine powder technology, especially the modification of cement by nanotechnology, will have practical significance for further promoting the development of high-performance cement and high-performance conc...
