High Stability Environmental Protection 80t / h Limestone Vertical Mill

Description

In the process of using limestone powder as a desulfurizer, the limestone powder needs to undergo a solid-liquid two-phase dissolution reaction, and the reaction rate is positive with the specific surface area of ​​the limestone particles. The smaller the particle size of the limestone powder particles, the larger the mass specific surface area, the better the dissolving performance of the limestone particles, and the higher the various related reaction rates.
However, the smaller the particle size of limestone, the higher the energy consumption for crushing. The sieving rate of limestone powder usually required to pass through a 325 mesh screen (44 microns) is 95%. At the same time, the particle size of limestone powder is related to the quality of limestone.
In order to ensure the desulfurization efficiency and the utilization rate of limestone reach a certain level, when the impurity content in the limestone is high, the limestone should be ground to be finer. Using traditional tube milling technology to prepare limestone powder has high energy consumption, low output, complex process flow, and difficult to control fineness and particle gradation. With the development of grinding technology, vertical grinding grinding technology is adopted, because it adopts the principle of material layer grinding, low energy consumption, stable product chemical composition, uniform particle gradation, and simple process flow.
