With the tightening of environmental protection policies, the lime deep processing industry has attracted much attention in recent years. In addition to traditional construction, metallurgy, agriculture and forestry, lime is also widely used in environmental protection fields such as sewage treatment and flue gas desulfurization. Lime deep processing mainly refers to the processing and application from limestone to lime. In short, limestone is calcined into lime, which is mainly composed of calcium oxide, also known as quicklime. Quicklime becomes mature lime after being digested with water, and its main component is calcium hydroxide. According to the market development needs, Guilin Hongcheng has developed and successfully applied a high-intelligent large-scale environment-friendly calcium hydroxide production line, which is conducive to the high-quality development of the lime deep processing industry.

Technical Indicators

Lime Deep Processing Process Flow

Production Process Flow

Calcination: The selected limestone is sent to the environmental protection lime kiln for high-temperature calcination to become quicklime.

Production Process Flow

Grinding: quicklime can be directly crushed by Raymond mill or vertical mill, and processed from block ash to powder ash.

Production Process Flow

Digestion: quicklime can also be further processed, sent to the calcium hydroxide production line, and turned into mature lime.

Production Process Flow

Powder classification+collection: the slaked hydrated lime can be screened directly through the powder concentrator. After collection, it will be the refined calcium hydroxide product.
