Ultrafine grinding mill techniques to make desulfurization calcium carbonate powder
calcium carbonate powder as desulfurizer FGD process required by the solid calcium carbonate - dissolving liquid two-phase reaction, the reaction rate is proportional to the specific surface area of the calcium carbonate particles. The smaller the particle size of calcium carbonate powder, the larger of mass ratio the surface area, better dissolving properties of calcium carbonate particles, the higher the rate of a variety of related reactions. However, the smaller the particle size of calcium carbonate, grinding mill grinding energy consumption is also higher. Usually requires calcium carbonate powder through a 325 mesh (44μm) sieved rate of 95%. Meanwhile calcium carbonate and calcium carbonate particle size quality related. To ensure the removal efficiency and calcium carbonate utilization reaches a certain level, when the high impurity content in calcium carbonate, calcium carbonate to some of the finer grinding.

The traditional tube grinding mill to make calcium carbonate powder, energy consumption, low yield, complex process, fineness and particle size distribution is difficult to control. With the development of grinding technology, the use of Ultrafine grinding mill desulfurization calcium carbonate powder preparation technology to become mainstream, because the use of the material layer Ultrafine grinding mill grinding principle, low power consumption (20 to 30 percent lower than the tube grinding mill power consumption), the chemical composition of the product stability, particle size distribution are homogeneous, the process is simple.

Ultrafine grinding mill desulfurization calcium carbonate powder preparation process Introduction
calcium carbonate goes into the Ultrafine grinding mill by a car or a forklift unloaded into the hopper, using a crushing calcium carbonate, calcium carbonate uniformly and continuously fed by the feeder crusher feed size is generally controlled at 400-500mm, the expected size of the control in about 15mm, crushed calcium carbonate into the calcium carbonate by the delivery device library, the library set up a stand-alone top precipitator dust. Crushed calcium carbonate from the bottom in the governor belt weigher batching, feeding the belt conveyor Ultrafine grinding mill, fineness of 250 mesh finished calcium carbonate. After grinding calcium carbonate powder through the conveyor into the finished products storage. Top with a single depot Library precipitator dust. Finished powder provided by the library at the end of bulk machine, into the bulk tank car transport factory.

Ultrafine grinding mill desulfurization calcium carbonate powder characteristics
Ultrafine grinding mill grinding process using material layer grinding principles, grinding pressure adjustable, low noise, low power consumption, small abrasion of materials adaptable, simple process, high system efficiency. System-wide vacuum operation, dust pollution. Vertical mill grinding process, and its products are homogeneous particle size distribution, product fineness adjustable (product fineness can reach more than 600 mesh), and the fineness of the product can be quickly measured, corrected.

Shanghai Clirik Machinery is the leader of calcium carbonate grinding mill supplier. Ultrafine grinding mill preparation desulfurization calcium carbonate powder production line process, using self-developed production equipment, process smooth, low investment start fast, easy production management. When selecting the production process solutions and equipment selection, mature, reliable new technology, new technologies, so technologically advanced, economical, practical and reliable, and attaches great importance to the comprehensive management of the environment, we can meet national standards.
