What equipment is better for circulating fluidized bed desulfurization limestone grinding in power plant?

By using column mill, the particle size distribution of limestone grinding is the closest to that of desulfurization limestone in CFB circulating fluidized bed boiler in the world at present. The grinding equipment has the best particle size ratio, and the wearing parts are the most durable (3-5 years), with stable performance and energy saving and consumption reduction. Its manufacturer is Changsha Shenxiang General Machinery Co., Ltd., and the mill is its national patent product, which is the key product of the national torch plan. At present, nine out of ten thermal power plants in China use row mills as limestone grinding equipment.
