Blast furnace slag micro powder compound type vortex superfine separator

Abstract

The invention discloses a blast furnace slag micro powder compound type vortex superfine separator which solves the technical problems of low production efficient, high energy consumption, serious air leakage and material collapse, low powder yield, low stability of specific surface area and the like of the field of micro powder separator relatively well by use of multiple innovative technologies such as vortex powder selection sealing, compound type superfine separation, micro powder cyclone separation, guide vane adjustment, snail-shaped direct air inlet, motor variable-frequency speed regulation and the like. The blast furnace slag micro powder compound type vortex superfine separator has the outstanding characteristics of simple structure, low price, high production efficiency, good powder selection quality, high powder yield and the like, is convenient to operate, avoids secondary pollution, is adapted to the technical transformation, equipment replacement and production capacity expansion, and improves the market demand of the product quality. The blast furnace slag superfine powder separated by the separator provided by the invention can replace cement clinker in a large proportion to be directly mixed in cement, and also can be used as fine powder component to be directly mixed in super-level concrete.

Description

technical field [0001] The invention relates to a building material machine, in particular to a compound eddy current ultra-fine separator for blast furnace slag micropowder used in cement production. technical background [0002] Cement is one of the most commonly used and most important building materials in the world, and cement clinker is an essential raw material for the production of cement. The production of cement clinker requires not only a large amount of raw materials such as limestone, clay, and iron powder, but also a large amount of energy resources such as raw coal and electricity; the production of cement clinker accounts for a large proportion of energy consumption in cement production and manufacturing. These are the main goals of saving energy in countries all over the world. [0003] Blast furnace slag is an industrial solid waste produced during the ironmaking process. The open-air storage of these blast furnace slags not only occupies a large amount o...

Problems solved by technology

However, on the one hand, the eddy current micro-powder separation machine has the disadvantages of large structure, high price, and large one-time investment, which is difficult for medium and small-scale mineral powder production enterprises; It reaches 75-85%, but there are still 15-25% of the ground micro-powders that cannot be selected, which not only wastes precious resources, but also wastes the completed grinding and powder selection energy.
