How to Produce Desulfurized Limestone Powder for Power Plant| Desulfurization Grinding Mill For Sale

Limestone is a mineral resource with rich reserves and wide distribution in China. With the rapid development of limestone industry, limestone has been widely used in building materials and industrial raw materials, as well as limestone powder for desulfurization of thermal power plants. How to produce desulfurization limestone powder in power plant? As the manufacturer of the desulfurization grinding mill in the power plant, HCMilling(Guilin Hongcheng) will analyze and answer the following questions for you.

Limestone gypsum wet flue gas desulfurization process is a commonly used desulfurization process in power plants. More than 90% of domestic thermal power plants use this method. The principle is to use the power plant desulfurization grinding mill to grind limestone into stone powder, and then make limestone slurry as the desulfurization absorbent. The limestone is mixed with the flue gas entering the absorption tower. The sulfur dioxide in the flue gas reacts with calcium carbonate in the slurry and the air entering the slurry, and finally generates gypsum, The sulfur dioxide in the flue gas is separated to avoid the environmental pollution caused by a large number of emissions. How to produce desulfurization limestone powder in power plant? As the limestone slurry in the absorption tower in the desulfurization system needs to be replaced regularly to maintain its activity, a special power plant desulfurization grinding mill is required to process limestone powder to prepare active limestone slurry. Large stones shall be roughly crushed first. Large limestone materials shall be uniformly fed by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing. The coarse crushed materials shall be screened by the vibrating screen and then transported to the impact crusher by the belt conveyor; Secondly, the medium and fine crushing is carried out. After the coarse crushed materials transported to the counter impact crushing are subjected to counter impact crushing, the circular vibrating screen is used to screen the materials subjected to counter impact crushing, and the larger granular materials are returned to the counter impact crushing for re crushing; If finer products or shaping are required, the crushed materials shall be sent to the sand machine for further crushing and shaping; Finally, the crushed limestone small pieces are sent to the silo by the elevator, and then sent to the grinding chamber of the mill for grinding by the vibrating feeder.

The above is the production process of desulfurization limestone powder in the power plant.
