Cement and mineral powder mixing homogenization process and equipment with efficient powder homogenization function

Abstract

The invention relates to a cement and mineral powder mixing homogenization process and equipment with high-efficiency powder material homogenization function, wherein the cement and mineral powder mixing homogenization equipment with powder material high-efficiency homogenization function includes cement storage tanks, mineral powder The powder storage tank, the mixing tank and the mixer, the outlets of the cement storage tank and the mineral powder storage tank are all connected to the inner cavity of the mixing tank, and the outlet of the mixing tank is connected to the inner cavity of the mixer through a pneumatic conveyor. Connected, the mixing tank is equipped with a first stirring device; the mixer includes a mixing box and a second stirring device installed in the mixing box, the bottom of the mixing box is provided with a slag discharge port, and is connected with the pneumatic conveyor through a feeding pipe There are a number of lower feed ports, and a side discharge port is opened on the upper part of the side wall of the mixing box. The present invention realizes three-stage stirring through the first stirring device, pneumatic conveying and second stirring device, which improves the uniformity of mixing materials; dries the falling mineral powder by hot air, which reduces the water content of mineral powder; Flow, dredge the clogged leakage hole.

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...

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
