Technology And Application of Lime Calcium Powder Production Line|What Is The Best HCM Lime Calcium Grinding Mill Machine?

Lime calcium powder, mainly composed of calcium hydroxide Ca (OH) 2, has the characteristics of good whiteness, high fineness, non-toxic and tasteless. It can improve the adhesion, water resistance, scrub resistance, mildew resistance and moisture absorption of coatings, and reduce costs for coating enterprises to improve product quality. HCMilling(Guilin Hongcheng), as the manufacturer of lime calcium grinding mill machine production line, our calcium hydroxide equipment has been widely used in the lime calcium powder production line, with an hourly capacity of 5-20 tons. The following is a brief introduction to the process and application of the lime calcium grinding mill production line.

Application of lime calcium grinding mill production line: From the material point of view, lime calcium powder is a 325~600 mesh white powder that is grinded by selecting and processing lime. At present, the coatings produced with lime calcium powder have passed the inspection of the National Testing Center, and meet the inspection requirements of GB18582-2008 Limit of Harmful Substances in Interior Decoration Materials and Interior Wall Coatings. So far. Lime calcium powder is widely used in putty powder, OK powder, thermal insulation mortar and even plastic, rubber and food fields. Take putty powder as an example. The main raw materials are calcium lime powder (30% of which is added), heavy calcium powder and glue powder binder. The product is made by mixing with a dry powder mixer. The product is environmentally friendly, non-toxic and tasteless. It is divided into interior wall and exterior wall. Exterior wall putty shall be resistant to wind and sun, so it has high adhesive property and high strength. Interior wall putty, good comprehensive index, environmental protection, non-toxic and tasteless. In recent years, environmental protection has been attached great importance by the state. In addition to being an applicable filler in traditional manufacturing, lime calcium powder has also been applied in sewage treatment, industrial desulfurization, agricultural production and other fields.

Process of lime calcium grinding mill machine production line: lime calcium powder is mainly composed of calcium hydroxide, so limestone is an indispensable raw material for processing. The basic process of the preparation process is as follows: select burnt lime, partially digest, remove dust, and crush to make white dry powder (fineness 325 mesh). According to the difference of calcium oxide content and metal impurities in limestone, the color and use of calcium ash powder are also different. The raw material of limestone is high quality, and the whiteness is high. The quality of burnt lime is good; The ash production equipment adopts dry digestion process, with accurate water control, and the fineness of the ash calcium powder produced is uniform. In the production process, the generated calcium carbonate and calcium hydroxide cross coexist in the lime slurry to form a tight crystal network, which significantly improves the strength of calcium lime powder.

Generally speaking, fine processed calcium lime powder can be used in plastics, coatings, food, metallurgy, environmental protection and other fields, but the specific production process and indicators are different due to different application fields, so different additives, mineral powder and auxiliary equipment and process parameters are required. HCMilling(Guilin Hongcheng)'s lime calcium grinding mill production line uses a five stage digester to produce lime calcium powder with higher purity and better quality. For the undigested lime slag, the lime slag material mill can also be configured for grinding processing to achieve waste free production.
