Abstract
The present invention discloses a method for producing portland cement clinkers by using wind blown sand for replacing clayey raw materials. The original production process does not need to be changed. The method of the present invention has the advantages of resource and energy source saving, adverse effect (caused by wind blown sand) reduction, etc., changes harmful materials into useful materials, improves the cement quality and the economic benefit, and is suitable for the generalization and application to cement enterprises in northwest regions in China.
Description
Technical field:
The invention belongs to building material field, relate to a kind of production method of silicate cement.
Background technology:
The silicate cement raw materials for production are generally Wingdale, clayey raw material (clay, sandstone, shale), and unburned coal gangue, iron powder etc., wherein except that a small amount of be to utilize the waste as coal gangue, other is Mineral resources.Along with developing rapidly of Cement industry, resource and energy consumption are more and more, and production cost improves, and is unfavorable for Sustainable development; And China's vast the Northwest sandstorm is on the rise, and yellow sand is engulfed ten thousand incline good farmland, grasslands, fills up the bridge opening, and danger side of body railway, highway communication influence people's productive life.Drift-sand also is a kind of siliceous material, SiO
2Content is 70%-80%, in sand industry development today of forming as yet, the utilization of drift-sand is still insignificant, domestic to drift-sand the application on manufacture of cement still do not have report.
Summary of the invention:
The purpose of this invention is to provide a kind of clayey raw material that utilizes in the drift-sand place of cement raw materials for production, produce the method for Portland clinker.
Technical scheme of the present invention is: with the clayey raw material in the drift-sand place of cement raw materials for production, the raw material weight percent is: Wingdale: drift-sand: unburned coal gangue: iron powder=82-88: 8-14: 2-6: 1-4.By above-mentioned raw-meal ingredient preparation raw material, levigately tail over percentage composition≤13% to the 0.08mm square hole sieve, go into kiln and calcine, obtain Portland clinker.
Advantage of the present invention is: 1, saved the consumption of clay and mineral wealth, the energy, helped Sustainable development.2, reduced the influence of drift-sand, turned bane into boon physical environment and human being's production life.3, this method does not change original production process, because drift-sand is through the wind natural selection, and fineness and quality height, it is convenient to adopt, and has reduced production cost, has reduced firing temperature, energy-saving and cost-reducing.4, improve clinker quality, improved economic benefit.
Embodiment:
The invention will be further described with production instance below:
Example 1: cover western cement company limited in February, 1999 production instance:
The raw material weight percent is a Wingdale: drift-sand: unburned coal gangue: iron powder=84.37: 10.60: 2.67: 2.12.The grog three ratio is KH=0.929; N=2.00; P=1.59.3 days=34.9/6.3 of grog ultimate compression strength/folding strength (MPa); 28 days=61.4/8.9.
Example 2: cover western cement company limited in April, 1999 production instance:
The raw material weight percent is a Wingdale: drift-sand: unburned coal gangue: iron powder=85.23: 10.32: 2.28: 1.98.The grog three ratio is KH=0.931; N=2.12; P=1.48.3 days=33.7/6.1 of grog ultimate compression strength/folding strength (MPa); 28 days=61.1/8.9.
Repeatedly finding that the raw material weight percent is a Wingdale: drift-sand: unburned coal gangue: iron powder=83-86: 9-11: 2-5: 1-3 in experiment and the production practice.
Provable by above example, drift-sand instead of clay raw material can the stably manufactured high-quality portland cement clinker.
Claims (2)
1, a kind of method of producing Portland clinker is characterized in that: with the clayey raw material in the drift-sand place of cement raw materials for production, the raw material weight percent is: Wingdale: drift-sand: unburned coal gangue: iron powder=82-88: 8-14: 2-6: 1-4; By above-mentioned raw-meal ingredient preparation raw material, levigately tail over percentage composition≤13% to the 0.08mm square hole sieve, go into kiln and calcine, obtain Portland clinker.
2, the method for production Portland clinker as claimed in claim 1 is characterized in that: the raw material weight percent is a Wingdale: drift-sand: unburned coal gangue: iron powder=83-86: 9-11: 2-5: 1-3.
