To make ceramsite a qualified product, two points need to be done: one is to generate gas inside at high temperature, and the other is to melt the surface at high temperature, so that the gas can be wrapped so that it cannot escape from the surface, and after cooling, a certain amount of gas is formed. strength.

According to the experience of the ceramsite industry and the exploration and analysis of research institutions, in order to fire qualified ceramsite, its composition has certain requirements before entering the roasting process. It meets the requirements. Taking the raw material preparation of Chongqing Yongchuan project as an example, two materials are used, namely sludge and shale.

Through the preliminary treatment of the raw materials, the two raw materials should be measured and proportioned. The process flow is as follows: the sludge is sent to the sludge tank for storage, sent to the sludge receiving hopper through the grab crane, and subjected to the hopper and screw conveyor. After the weight loss scale is measured, it is sent to the double-shaft mixer by another screw conveyor; After the two materials are evenly mixed in the double-shaft mixer, they enter the aging bin for 7-15 days through the belt conveyor. The aged materials are taken out by the reclaimer and sent to the granulation section through the belt conveyor.

In this process, two aspects need to be considered at the same time, one is that the ingredients after mixing the two raw materials meet the requirements, and the other is that the moisture content meets the requirements, in which the ingredient requirements take precedence over the moisture requirements. Through the previous batching analysis, the ratio relationship between sludge and shale is determined. After measuring the two, they are stirred evenly and sent to the aging warehouse. The aging process is also called the homogenization process. The purpose is to pass the raw materials. A series of physical and chemical reactions between the raw materials achieve the refinement and mixing of raw materials in the microscopic field, so that the composition of the mixture before entering the kiln is uniform and stable, and the working conditions of the kiln can be stabilized.
