Embodiment 1

[0028] see figure 1 , in an embodiment of the present invention, a method for preparing European-style interlocking tiles using high-silicon tailings, comprising the following steps:

[0029] Step 1), high-silicon tailings pretreatment: Extrude the high-silicon tailings with a moisture content of 25% into mud sticks with an impurity removal extrusion machine, place them in a horizontal dryer to dry, and reduce the moisture to below 15%. Make it finalized, and then send the tailings to the pre-homogenization shed for homogenization;

[0030] Step 2), batching: put the raw material in the feeder, and set it through the computer according to the proportion of the process formula;

[0031] Step 3), blending and homogenization: After the blended raw materials are evenly mixed by the mixer, they are transported to the transfer warehouse by the belt for homogenization, and the blended raw materials are homogenized again by sliding down through the cross section during unloading;

...

Embodiment 2

[0048] Repeat Example 1 according to the same steps, and the difference from Example 1 is: step 11), calcining: the embryo body after glazing is placed in a roller kiln for firing, and the temperature is controlled at 1350 degrees.

Embodiment 3

[0050]Repeat Example 1 according to the same steps, and the difference between Example 1 and Example 2 is: step 11), calcining: the embryo body after glazing is placed in a roller kiln for firing, and the temperature is controlled at 1400 degrees.

Abstract

The invention discloses a method for preparing European type interlocked tiles by using high-silicon tailings and relates to the technical field of resource utilization of dressing and smelting wasteresidues. The method comprises the following steps: step 1) pretreating the high-silicon tailings; step 2) preparing materials; step 3) mixing and homogenizing; step 4) grinding; step 5) homogenizingand granulating; step 6) fluidizing and drying; step 7) sieving and ageing; step 8) compressing; step 9) drying; step 10) glazing; step 11) calcining, and step 12) treating flue gas. The method disclosed by the invention has the advantages of novel design and simple technology; the high-silicon tailings are utilized as a main raw material, harmless and resourceful utilization of the high-silicon tailings is achieved, and sustainable development of the whole golden industrial chain is improved; bauxite, Laiyang clay and quartz are utilized as auxiliary materials, so that the whole performance of a product is better; by means of high-temperature calcining, FeS2 in the high-silicon tailing can be slowly decomposed; thus, the sulfur content in the European type interlocked tiles is reduced, and the product is ensured to achieve environmental friendliness and reach the standard.

Description

technical field [0001] The invention relates to the technical field of resource utilization of dressing and smelting waste slag, in particular to a method for preparing European-style interlocking tiles by using high-silicon tailing slag. Background technique [0002] As a new type of roofing material that has emerged in the past 10 years, European-style interlocking tiles have the characteristics of light weight, high strength, low water absorption, high impermeability, frost resistance, and good decorative effects. They have gradually replaced clay tiles and cement tiles. It has become a main roofing material and has been widely produced and applied. The market demand is large and the prospect is broad. [0003] However, the main raw material of the current European-style interlocking tiles is clay, which has high cost and low product performance. Therefore, those skilled in the art provide a method for preparing European-style interlocking tiles by using high-silicon tai...
