Embodiment 1

[0015] Take 10kg of sludge, 85kg of mining solid waste or metallurgical solid waste, and 5kg of additives. In the process of using it to make high-strength ceramsite, pretreatment is carried out first, that is, the sludge, mining solid waste or metallurgical solid waste is put into the pretreatment equipment for harmless treatment to eliminate odors. When all the odors are removed from these three materials After crushing, then mix the crushed three kinds of materials and add the above-mentioned additives to it. The additives can be bentonite or pottery clay or waste clay ore powder. The final material is input into the equipment for uniform stirring. Since the sludge, mining solid waste or metallurgical solid waste and additives all contain a certain amount of water, the uniformly stirred material is put into the drying equipment for drying, and the drying The moisture content of the final material is kept between 8-15%; then the three mixed materials are dried and put into t...

Embodiment 2

[0017] Get 20kg of sludge, 70kg of mining solid waste or metallurgical solid waste, and 10kg of additives, and make high-strength ceramsite according to the method in Example 1.

Embodiment 3

[0019] Get 17kg of sludge, 75kg of mining solid waste or metallurgical solid waste, and 8kg of additives, and make high-strength ceramsite according to the method in Example 1.

Abstract

The invention relates to a composition and a method for preparing high-strength ceramic particles. The composition is prepared from sludge, mining solid waste or metallurgical solid waste and an additive. A preparation method of the composition comprises the following steps: firstly carrying out innocent treatment on all materials of the sludge and the mining solid waste or metallurgical solid waste, then smashing the materials, adding the additive after mixing the smashed materials, feeding the mixed materials in a device, uniformly stirring and drying, then putting the dried materials in a pelletizing device, processing the dried materials into raw material balls, firing the raw material balls in a roasting device, and cooling after firing, thus preparing the high-strength ceramic particles. The high-strength ceramic particles prepared by utilizing the composition have higher strength, and the cost is very low; meanwhile, the problems of environment pollution, waste of land resources and the like can be solved.

Description

technical field [0001] The invention relates to a composition for making high-strength ceramsite and a method for making ceramsite using the composition. Background technique [0002] Ceramsite is ceramsite particles. Most of the appearance characteristics of ceramsite are round or oval spheres, but there are also some imitation gravel ceramsites that are not round or oval spheres, and are in the shape of irregular gravel. The shape is different due to different crafts. Its surface is a hard shell, which is made of pottery or glaze, which has the function of water-proof and air-retaining, and gives ceramsite a higher strength. In addition, ceramsite also has the characteristics of heat preservation, heat insulation, excellent fire resistance, strong shock resistance, high frost resistance and durability. In the prior art, ceramsite is usually made of light sand aggregate or ordinary sand, cement, clay, admixture and water. Sand aggregate or ordinary sand, cement, admixture...
