Embodiment 1

[0081] The method for making cement clinker by using artificial slate wastes comprises the steps of:

[0082] In step 1, 80 parts of artificial stone calcium-aluminum board waste and 13 parts of quartz stone board waste are mixed, dried, and ground, and the obtained waste mixture is sieved with a sieve with an aperture of 0.080 mm, and the sieve residue is 13%. Sieve through a 0.20mm sieve, and the remaining 0.8% is sieved;

[0083] In step 2, the steel slag is ground with a mill, sieved with a sieve with an aperture of 0.080mm, and the sieve residue is 12.8%, and then sieved with a 0.20mm sieve with an aperture, and the sieve residue is 0.75%;

[0084] Step 3 Take 7 parts of ground steel slag and mix them evenly with the above-mentioned waste mixture to obtain cement raw meal. The cement raw meal is sieved with a sieve with an aperture of 0.080mm, and the sieve residue is 13%, and then passed through a sieve with an aperture of 0.20mm Sieve, the sieve residue is 0.4%;

Embodiment 2

[0109] In this embodiment, the steps of the method for producing cement clinker from artificial slate wastes are the same as those in Embodiment 1, except that the ratio of raw materials is changed.

[0110] The proportion of artificial stone calcium aluminum plate waste, quartz stone plate waste and steel slag is:

[0111] Artificial stone calcium aluminum plate waste: 84.1 parts;

[0112] Quartz slab waste: 10.3 parts;

[0113] Steel slag: 5.6 parts;

[0114] The parts are parts by mass.

[0115] In the present embodiment, the artificial stone calcium aluminum plate waste, its component content percentage is as shown in table 7:

Abstract

The invention relates to a cement clinker production method by utilization of artificial slabstone waste. The artificial slabstone waste is used as raw materials, cement is fired through a drying method preheater, the artificial slabstone waste can be thoroughly processed, part of natural raw materials can be replaced, and energy-saving and emission-reducing purposes are achieved. The method includes the following steps: mixing artificial stone calcium aluminum plate waste, artificial quartz stone waste and steel slag according to a mixing ratio, drying, grinding, screening, and evenly mixing the mixed materials to obtain cement raw materials, and calcining the cement raw materials to obtain cement clinker by adopting a calcining process of an existing novel drying method kiln which is provided with a precalcining kiln. Cooled cement clinker is grinded through a mill, and the cement clinker meeting production requirements is obtained.

Description

technical field [0001] The invention relates to a method for producing cement clinker by using artificial slate waste. technical background [0002] Artificial stone, as a new type of healthy and environmentally friendly product in line with the national sustainable development strategy, was introduced into the domestic market in the 1980s. Although my country's artificial stone industry started late, after more than ten years of rapid development, it has become the preferred material for cabinet countertops. The industry presents a very gratifying situation, and a consumer market with huge potential has been cultivated, ranking among the top in the world in terms of market size and application penetration rate. According to incomplete statistics, there are nearly 10,000 large and small artificial stone slab manufacturers in the country. In 2010, the total sales of artificial slate enterprises in the country exceeded 12 billion yuan, and the export was nearly 200 million US...
