Nowadays, for the desulfurization process of power plants, the quality, fineness, particle distribution and reactivity of limestone powder have a direct impact on the desulfurization effect. So how do you prepare limestone powder suitable for power plant desulfurization process in the industry?

Raymond mill

The equipment required for the preparation process of desulfurized limestone powder mainly includes vibrating feeder, jaw crusher, grinding mill, bucket elevator, belt conveyor, regulating silo, control cabinet and so on. After the large-sized limestone is crushed to the required particle size by the jaw crusher, it will be sent to the storage hopper by the bucket elevator, and then uniformly and continuously fed into the grinding mill by the vibrating feeder, and the limestone powder after grinding It is blown by the wind and graded by the classifier; the limestone powder conforming to the fineness enters the cyclone powder collector through the pipeline and is separated and collected. The collected limestone powder product is sent to the stone powder bin by the conveying device for use in desulfurization. The unqualified particles are smashed to the wall of the cylinder after being separated by the separator, and are returned to the grinding mill for grinding. The whole system is operated under negative pressure, and the dust does not overflow to achieve a clean effect.

Founded in 2003, Guilin Hengda Mining Machinery Co., Ltd. has been engaged in R&D, manufacturing, technical solutions and supporting products for large-scale equipment required for national infrastructure construction projects such as construction, energy, and transportation.
