Different applications of power plant desulphurisation mill in desulphurisation process

Limestone desulphurisation is currently the more mature international desulphurisation process, effectively removes the sulphur dioxide produced by coal in the combustion process, and gypsum ore resources, so in our country is also a project strongly supported by the government, but in the process of desulphurisation Raymond mill plays a different role in completing the process of different production processes.

Can be used for power plant desulphurisation of limestone not for two kinds, one is calcium carbonate, one is calcium oxide, compared to calcium oxide desulphurisation effect is better, the two minerals by raymond mill grinding into fine powder used in different production stages of desulphurisation use. Such as calcium carbonate powder with water to make a slurry and then pumped to the absorption tower and coal combustion flue gas mixing, after mixing the flue gas in the sulfur dioxide, calcium carbonate, air together with the reaction of calcium sulfate, sulfur dioxide at this time from the flue gas separated from the calcium sulfate in the continuous generation of calcium sulfate at the same time to reach saturation state of calcium sulfate will be crystallised to generate dihydrate gypsum, after dewatering, concentration treatment and discharge with the conveyor out to become the Gypsum ore resources. In the desulphurisation process, calcium oxide is mostly used for furnace desulphurisation, calcium carbonate is mostly used for flue desulphurisation, so Raymond machine in the grinding process to grind two different materials for different production stages of desulphurisation process.

Although calcium oxide desulphurisation effect is better, but the generation of calcium oxide needs to be formed by high-temperature calcination of calcium carbonate, calcination process requires a large amount of capital investment costs, consider the capital investment problem, many manufacturers may choose to use calcium carbonate desulphurisation directly, in this way, from the mine to the limestone ore only after crushing, grinding can be used, compared to reduce the cost of a lot of money, and sulfur removal effect is also Good, so for different manufacturers of desulphurisation process to choose a slightly different way. For thermal power plant desulphurisation or choose calcium oxide, calcium carbonate combined with more, while some steel mills, large machinery and equipment processing plants may be in the consideration of cost issues when choosing a slightly different, but regardless of calcium carbonate or calcium oxide, the general mill can complete its grinding process.

For a small amount of manufacturers Raymond mill to play a benefit, but if the required daily output of lime powder is large, we recommend that you can choose high-pressure mill, European version of the mill grinding and processing, especially European grinding equipment is not only a large output, high efficiency, the production of finished products of excellent quality, good specifications of the user's power plant desulphurisation effect is better.
