Spray inside of boiler calcium and limestone – gypsum flue gas desulfurization purification after combustion, is the world’s most mature technology, with the most widely used technology to control sulfur dioxide emissions. Wherein desulfurization with limestone powder or gypsum powder requires 250 mesh -325 mesh particle size.

Power 250 mesh and 325 mesh powder Limestone Limestone powder, the main production processes include: transport limestone, limestone storage, milling limestone, limestone powder storage and shipment.

250 mesh and 325 mesh powder Limestone powder production equipment includes crusher equipment and mill equipment, which selected according to the particle size of limestone ore, depending on particle size of about 1200mm, requires the use of crusher crusher, crushing to 30-40mm, can enter the milling machine for milling. Usually the final grinding particle size have an impact on its desulfurization effect, which is the need for power plant desulfurization limestone powder particle size of 250 mesh -325 mesh.

Preparation of 250 mesh and 325 mesh limestone powder, there are two devices, one is: MTW European version of the mill, and the other is LM vertical milling machine, vertical milling machine which yield than MTW European version of the mill powder machine will yield bigger, according to the plant selectable actually needed. MTW European version of the mill and LM vertical milling machine, in terms of powder preparation more significant than the energy-saving ball mill, a drying effect, small footprint, the advantages of civil engineering investment and, at present, most of the preparation plant desulfurization limestone pink vertical mill began using domestic programs, such as Wenzhou Power Plant, Changxing Power Plant, Xuzhou Tang Power Plant, Datang Power Douhe point to, Xiangtan power plant desulfurization systems are used domestically vertical mill program, the trend has replaced the ball milling limestone trend.
