Cement and mineral powder mixing and homogenizing process and apparatus with efficient powder homogenizing function

Abstract

The invention relates to a cement and mineral powder mixing and homogenizing process and apparatus with an efficient powder homogenizing function. The cement and mineral powder mixing and homogenizing apparatus with the efficient powder homogenizing function comprises a cement storage tank, a mineral powder storage tank, a mixing tank and a mixer. Discharging ports of the cement storage tank and the mineral powder storage tank are both communicated with an inner cavity of the mixing tank, a discharging port of the mixing tank is communicated with an inner cavity of the mixer through a pneumatic conveyor, and a first stirring device is arranged in the mixing tank. The mixer comprises a stirring box and a second stirring device installed in the stirring box, the bottom of the stirring box is provided with a slag discharging port and a plurality of lower feeding ports communicated with the pneumatic conveyor through feeding pipes, and the upper portion of the side wall of the stirring box is provided with a side discharging port. According to the cement and mineral powder mixing and homogenizing apparatus, three-stage stirring is realized through the first stirring device, the pneumatic conveyor and the second stirring device, so that the mixing uniformity is improved; falling mineral powder is dried through hot air, so that the water content of the mineral powder is reduced; and blocked material leaking holes are unblocked through the flowing of hot air.

Description

technical field [0001] The invention relates to the technical field of powder mixing, in particular to a cement and mineral powder mixing homogenization process and equipment with high-efficiency powder homogenization function. Background technique [0002] In recent years, with the continuous development of building materials technology, new technologies in the building materials industry continue to emerge. As a technical highlight of the cement industry, high-fine slag powder has attracted the attention of the whole industry. Due to the development of its deep potential, it is rapidly changing the original grinding process. Technologies such as compounding high-fine powder technology in cement, clinker powder and high-fine powder blending technology came into being. New technology must be guaranteed by new technical equipment, so various cement mixers have begun to appear. [0003] However, the uniformity of the existing cement mixer is low, which affects the homogeneit...

AI Technical Summary

Problems solved by technology

[0003] However, the uniformity of the existing cement mixer is low, which affects the homogeneity requirements of cement and mineral powder, and because the production standard of mineral powder is low, the water content often exceeds the standard, so the water is brought in after mixing. As a result, the water content of the mixed cement and mineral powder exceeds the standard, which is prone to poor fluidity and arching
