Problems solved by technology

[0002] The use of industrial waste residues to produce cement not only conforms to the concept of protecting the environment and reducing pollution, but also has positive social effects of turning waste into treasure, reducing industrial waste disposal and production costs. At present, some cement companies have successfully used industrial waste residues to produce cement. Cement, however, it is not difficult to see that there are mainly the following deficiencies in the existing public technology of utilizing industrial waste production: the quality of cement is not stable, the strength is low, and it cannot meet the requirements of large-scale construction projects.

Embodiment Construction

[0008] The present invention will be further described below in conjunction with specific embodiment:

[0009] The process of utilizing industrial waste residue to produce high-strength cement, the process steps are as follows: 1. Production of cement clinker: according to the batching plan of high silicon rate N=3.10, high alumina rate P=1.80 and high limestone saturation rate KH=0.80, use a computer Select calcium carbide mud, white ash slag, quartz sand beneficiation sludge, iron powder ore beneficiation sludge, and fly ash as five raw materials for batching and control the feeding to carry out raw meal grinding and raw meal homogenization, and then make the raw meal enter the rotary calcination Carry out calcination in the kiln, and then produce cement clinker; 2. Production of cement products: use a computer to select six raw materials such as fly ash, stone powder, cement clinker, desulfurized gypsum, dicyandiamide slag, and metal magnesium reduction powder for batching a...

Abstract

The invention relates to a process of producing high-strength cement by using industrial waste residues. The process comprises the following steps: 1, producing a cement clinker, namely dosing four raw materials (microcomputer selected limestones, quartz sand beneficiation sludge, iron powder ore beneficiation sludge and coal ash) in percentage by weight according to a dosing scheme of high silicon rate, high aluminum oxide rate and high limestone saturation factor, controlling blanking to grind and homogenize raw materials, then feeding the raw materials into a rotary calcining kiln and calcining so as to produce the cement clinker; 2, producing a cement product, namely dosing five raw materials (microcomputer selected limestones, coal gangues, cement clinker, desulfurized gypsum and mineral powder) in percentage by weight and controlling blanking to grind and homogenize cement so as to produce the cement product. The process provided by the invention has the advantages of not only satisfying the environment-friendly idea of protecting the environment and reducing pollution, but also having positive social effects of turning waste into wealth and lowering the disposal and production costs of industrial waste residues. The produced cement is stable in quality and high in strength.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a process for producing high-strength cement by using industrial waste residue. Background technique [0002] The use of industrial waste residues to produce cement not only conforms to the concept of protecting the environment and reducing pollution, but also has positive social effects of turning waste into treasure, reducing industrial waste disposal and production costs. At present, some cement companies have successfully used industrial waste residues to produce cement. Cement, however, is not difficult to see from the existing disclosed technologies of industrial waste production that there are mainly the following deficiencies: the quality of cement is unstable, and its strength is low, which cannot meet the needs of large-scale construction projects. Contents of the invention [0003] The purpose of the present invention is to provide a process for producing h...
