The nature of the product in order to meet the needs of wastewater treatment lime lime, lime sales for a long time the sewage treatment, the production of metallurgical lime or lime main raw material of choice, and many more dense limestone-based sales wastewater treatment lime, limestone that is common. Because lime sewage treatment plant, the biggest feature is the performance of dense limestone in the crystal structure and texture Hardness smaller it has a dense fine particles are calcined lime ideal raw materials. Lime: for steelmaking, the particle size of the active lime requirement is to ensure that the requirements of steel-making process at the time of slagging speed and effectiveness. If the lime particle size is too large, the reaction time will lead to lime particles and molten steel is lengthened, so slow down and affect slagging slagging effect. Conversely, if the particle size is too small lime, at the time of steelmaking dust particles or splashes easily cause deteriorated operating environment.
