What equipment is required for calcium hydroxide production line
Calcium hydroxide (Ca (OH) ₂) is an important chemical raw material widely used in various fields such as environmental protection, construction, and medicine. To ensure efficient production of calcium hydroxide, a complete set of production line equipment must be equipped. The equipment configuration of this production line needs to be comprehensively considered based on the properties of raw materials, production requirements, and process flow. The following are several common types of key equipment in calcium hydroxide production lines.
Firstly, the processing of raw materials is the foundation of calcium hydroxide production. The production of calcium hydroxide usually uses quicklime (calcium oxide) as raw material, which needs to be preliminarily crushed by a crusher to meet the particle size required for subsequent reactions. The crusher not only needs to have high work efficiency, but also strong wear resistance and stability to meet the needs of large-scale production.
Next, quicklime needs to react with water to produce calcium hydroxide. Rapid response and control of heat are crucial in this process. The commonly used equipment is a digestion tank. The digestion tank has the characteristics of high temperature resistance and corrosion resistance, which can ensure a strong reaction between water and quicklime, quickly producing calcium hydroxide. The digestion tank is usually equipped with a stirring system to ensure a uniform reaction process and prevent clumping or incomplete reactions.
The reacted calcium hydroxide slurry needs to be dehydrated and dried to obtain a solid product. Filter machines are usually used to remove impurities and moisture from the reaction solution, completing preliminary dehydration. The dehydrated material will be sent to a dryer for deep drying treatment to ensure that the moisture content of calcium hydroxide is controlled within a reasonable range. Drying machines often use fluidized bed drying technology or rotary kiln drying systems to ensure drying efficiency and product quality.
Finally, the finished calcium hydroxide needs to be cooled, sieved, and packaged. The cooling machine is used to cool down the dried calcium hydroxide to prevent high temperatures from affecting subsequent operations and product quality. The screening machine is used to separate materials with unqualified particle size, ensuring the uniformity of the product. The screened calcium hydroxide is sent to the packaging equipment for automated packaging, making it easy to transport and store.
These devices form the core of the calcium hydroxide production line, and by optimizing the equipment configuration of each link, production efficiency and product quality can be significantly improved to meet different industrial needs.
