Problems solved by technology

[0003] However, because the traditional cement products currently used for home decoration contain more harmful substances such as sulfur, their environmental protection performance can no longer meet people's requirements.
In addition, in the manufacturing process of traditional cement products, the cement clinker is ground by using metal grinding bodies such as high chromium, so the color depth of the final cement product will be increased, thereby affecting the color aesthetics of the cement product. Not suitable for home improvement applications

Embodiment 1

[0028] This embodiment provides a masonry cement suitable for home decoration and a manufacturing method thereof. Specifically, the manufacturing method of the masonry cement includes the following steps:

[0029] S1. Weigh 0.8t of limestone, 0.13t of coal gangue, 0.06t of copper slag and 0.01t of silica, and set aside.

[0030] S2. Mix the weighed limestone, coal gangue, copper slag and silica together, and grind until the sieve residue after passing through an 80 μm square hole sieve is 5%, to obtain raw meal.

[0031] S3. After homogenizing the raw meal, it is placed in the five-stage cyclone pre-decomposition system of the existing dry-process cement kiln system, and preheated and decomposed by high-temperature oxygen-poor combustion technology; the temperature control of the pre-heated decomposed process At 860°C, specifically, the outlet temperature of the first-stage cylinder of the five-stage cyclone pre-decomposition system is controlled at 360°C, and then the compreh...

Embodiment 2

[0036] This embodiment provides a masonry cement suitable for home decoration and a manufacturing method thereof. Specifically, the manufacturing method of the masonry cement includes the following steps:

[0037] S1. Weigh 0.9t of limestone, 0.079t of coal gangue, 0.02t of copper slag and 0.001t of silica, and set aside.

[0038] S2. Mix the weighed limestone, coal gangue, copper slag and silica together, and grind until the sieve residue after passing through an 80 μm square hole sieve is 20%, to obtain raw meal.

[0039] S3. After homogenizing the raw meal, it is placed in the five-stage cyclone pre-decomposition system of the existing dry-process cement kiln system, and preheated and decomposed by high-temperature oxygen-poor combustion technology; the temperature control of the pre-heated decomposed process At 890°C, specifically, the outlet temperature of the first-stage cylinder of the five-stage cyclone pre-decomposition system is controlled at 370°C, and then the comp...

Embodiment 3

[0044]This embodiment provides a masonry cement suitable for home decoration and a manufacturing method thereof. Specifically, the manufacturing method of the masonry cement includes the following steps:

[0045] S1. Weigh 0.823t of limestone, 0.12t of coal gangue, 0.05t of copper slag and 0.007t of silica, and set aside.

[0046] S2. Mix the weighed limestone, coal gangue, copper slag and silica together, and grind until the sieve residue after passing through an 80 μm square hole sieve is 10%, to obtain raw meal.

[0047] S3. After homogenizing the raw meal, it is placed in the five-stage cyclone pre-decomposition system of the existing dry-process cement kiln system, and preheated and decomposed by high-temperature oxygen-poor combustion technology; the temperature control of the pre-heated decomposed process At 880°C, specifically, the outlet temperature of the first-stage cylinder of the five-stage cyclone pre-decomposition system is controlled at 365°C, and secondly, the...

Abstract

The invention discloses masonry cement applicable to home decoration and a production method therefor and belongs to the technical field of cement production. The production method for the masonry cement comprises the following steps: firstly, blending limestone, coal gangue, copper ore slag and silica together, and carrying out pulverizing, so as to obtain a crude material; then, subjecting the crude material to homogenizing treatment, and then, carrying out pre-pyrolyzing treatment by a high-temperature lean-oxygen combustion technology; then, subjecting the crude material subjected to the pre-pyrolyzing treatment to high-temperature calcination treatment, and subjecting high-temperature clinker to quick cooling, so as to obtain cement clinker; and finally, mixing the cement clinker, desulfurized gypsum and admixtures, and then, carrying out pulverizing with a ceramic grinding body, thereby obtaining the masonry cement. The masonry cement product prepared by the method is low in content of harmful ingredients, has relatively high color attractiveness and is very adaptable to home decoration.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to masonry cement suitable for home decoration and a manufacturing method thereof. Background technique [0002] Today, with the increasing awareness of environmental protection, users have also put forward safety, green and environmental protection requirements for family house decoration. Therefore, the choice of home improvement materials has begun to shift towards environmentally friendly, safe, and pollution-free green materials. [0003] However, because the traditional cement products currently used in home decoration contain more harmful substances such as sulfur, their environmental protection performance can no longer meet people's requirements. In addition, in the manufacturing process of traditional cement products, the cement clinker is ground by using metal grinding bodies such as high chromium, so the color depth of the final cement product will be increase...
