What is the logical utilization of lime slag?

Rational utilization of lime slag: how to deal with lime slag with a moisture content of 50%? We Lime Slag Mill Factory understands that a large amount of lime slag will be produced in the lime production process, and the lime slag contains chemical components that will have a great impact on the soil if it is directly buried. Under the call of environmental protection utilization of solid waste, lime enterprises in many places reprocess and utilize lime slag. After years of accumulation of experience in lime slag treatment technology, the technology of lime slag treatment and utilization is very mature, and the market demand for lime slag treatment and reuse is also increasing.

Due to the high moisture content of lime slag, the moisture content varies from 50-60%. The processing of lime slag with high moisture content requires drying of lime slag first. It can be dried by natural stacking and drying, or it can be equipped with a dryer for drying. The wet lime slag is dried before processing. Lime slag is widely used after processing, such as: the application of phosphate rock tailings and lime slag in the production of phosphate compound fertilizer. Phosphate ore tailings and lime slag in the production of phosphate fertilizer are wastes in the process of phosphate compound fertilizer production. The stacking not only takes up a lot of land, but also seriously damages the ecological environment and causes environmental pollution if the stacking is handled or managed poorly. Therefore, it is necessary to explore a scientific and effective way to comprehensively utilize phosphate rock tailings and lime slag to achieve the purpose of turning waste into treasure so as to realize the sustainable development of the phosphate fertilizer industry; in addition, the use of waste lime slag to produce potassium carbonate and calcium hydroxide: The chlorohydrin method waste residue is put into the sedimentation scrubber, stirred, washed with water, and then left to stand, so that the solution becomes an emulsion mainly composed of calcium carbonate and calcium hydroxide; it reacts with the neon potassium amide solution on the alkali-resistant enamel React in the container, stir and heat, carry out chemical reaction, generate potassium carbonate and calcium hydroxide mixed solution, obtain potassium carbonate crystal product. The invention can turn waste into wealth and create considerable economic benefits for enterprises.

Because lime is widely used in many industries, the composition and use of lime residue produced by lime in each industry are different.
