Novel mineral powder produced by using sludge and preparation method of novel mineral powder
The invention relates to novel mineral powder produced by using sludge. The novel mineral powder produced by using sludge is prepared from the following raw materials in percentage by mass: 40-60% of sludge and 40-60% of slag. The invention further provides a preparation method of the novel mineral powder. The preparation method comprises the following steps: firstly, uniformly mixing and stirring the sludge and slag weighed in a mass ratio by machinery for hydration reaction; then feeding the mixture into a drying kiln to be dried at 200-400 DEG C to form a novel hydrated mineral composition and a novel mineral powder product of an active vitreous body; and finally pulverizing the dried mineral powder product to form a novel mineral powder product. According to the novel mineral powder provided by the invention, the output can be improved by 50%, the electricity can be saved by 50%, and the cost can be lowered at a rate of 150 yuan/ton. The novel mineral powder provided by the invention provides a novel technical process for sludge treatment, so that the sludge is massively used, the mineral resources are saved, 90% of CO2 emission is reduced, the environment is prevented from secondary pollution, and a novel technology and a novel method for resource utilization of solid wastes are realized.
