Processing method of natural scoria activity

Abstract

The invention discloses a method for stimulating the activity of natural volcanic cinders. The method realizes heat processing of volcanic cinders through the steps of crushing, delivery, heating and dust collection. A feeding device, a crushing device and a conveying device are arranged before a feed inlet of a rotary treatment machine so as to ensure regular grains of volcanic cinders are feed in the rotary treatment machine constantly and uniformly. An air heating furnace which uses coal as fuel is arranged at the feed inlet of the rotary treatment machine, the heat generated during coal burning is drawn in the rotary treatment machine by a fan arranged at rear side of the rotary treatment machine so the volcanic cinders are heated. The inside of the rotary treatment machine is provided with a raise plate to throw the volcanic cinders on a cross section of the rotary treatment machine uniformly to heat the volcanic cinders evenly and constantly, so the stimulation of the activity of the volcanic cinders is realized and the optimal stimulation of the activity of the volcanic cinders can be realized through temperature control. The volcanic cinders discharged from a discharge end of the rotary treatment machine are delivered to a storage cylinder by a conveyer. The dust containing gas generated in the rotary treatment machine is filtered by a bag dust catcher and discharged into the air. The method has the characteristics of high heat exchange rate, high heat transmission speed, simple operation, convenient maintenance, high operation factor, long service life and high activity of the treated volcanic cinders and can achieve the highest utilization rate of volcanic cinder resources.

Description

Technical field [0001] The invention relates to an unconventional treatment method, in particular to a treatment method used as cement admixture-volcanic slag activity. Background technique [0002] The existing domestic cement admixtures are generally natural volcanic ash, fly ash from power plants, slag from iron and steel plants, natural limestone, and cinder from production and life. Many admixtures, especially some natural waste residues, have not been treated in a targeted manner, and have not fully exerted their performance as cement admixtures, that is to say, they have not fully exerted their due activity, resulting in a serious waste of resources. In addition, because the activity of the admixture is not fully brought out, the amount of clinker in the cement has to be increased, and due to the increase in the amount of clinker in the cement, the waste gas discharged from the cement kiln increases, and the environmental pollution is aggravated. [0003] There is no...
