Abstract

The invention relates to oil shale slag haydites with light mass and high strength and the production method thereof, which belongs to constructional material. The invention is composed of oil shale slag, gas evolution materials, plasticizing materials and stable gas evolution materials according to the ratio of weight parts, grinding with materials, stirring with pre-watering, granulating by granulator after even agitation, then being sent into rotating kiln with double cylinders by belt conveyer for preheating, drying, roasting and cooling, the rotating kiln with double cylinders takes coal powders as the fuel, spraying the coal powders into the rotating kiln with double cylinders according to the speed and the dosage via speed variable motor driving screw conveyer and fan, controlling the preheating temperature between 450-850 DEC G and the calcination temperature between 1150-1250 DEC G. The invention has the advantages that utilizing the discarded oil shale slag to produce the haydite is an innovation. Further, the invention not only changes waste into valuable, but also is environment-friendly and has distinctive economic benefit and social benefit.

Description

technical field [0001] The invention relates to building materials, in particular to a light-weight high-strength ceramsite from kerogen shale slag and a production method thereof, especially to an ellipsoidal kerogen shale slag light-weight high-strength ceramsite prepared from kerogen shale slag as a raw material and a production method thereof. Background technique [0002] As we all know, with the development of the national economy, people's living standards continue to improve, the construction industry is developing rapidly, and the demand for new building materials in the construction industry is more urgent. Ceramsite is a kind of artificial concrete lightweight aggregate. Compared with natural aggregates such as gravel and river pebbles, it has a lower density, a honeycomb structure inside, and a closed and hard shell on the outside; the structure of ceramsite The characteristics make it low in density, and it also has high strength while maintaining heat insulation...
