Calcium Hydroxide Production Line Solution
The calcium hydroxide production line is also a mature and efficient lime hydration plant. Using high-quality quicklime as raw material, high-quality calcium hydroxide products are produced through crushing, calcination, digestion, dust removal, and packaging. You can choose an integrated production line that includes lime calcination. You can also choose a standardized production line that does not include lime calcination.
Calcium hydroxide is widely used in wastewater treatment, flue gas desulfurization, the chemical industry, and the pharmaceutical and food industries. Market demand is strong. Investing in a calcium hydroxide production line is a stable and profitable option.
Four Advantages of a Calcium Hydroxide Production Line
Good product quality
It uses an advanced automatic digestion machine. It can precisely control the water-cement ratio, reaction temperature, and time. It ensures that quicklime can be fully and uniformly converted into highly active calcium hydroxide.
High efficiency
The production line adopts automated production, achieving continuous operation throughout the entire process. It utilizes a PLC central control system, where parameters are monitored and adjusted in real-time. Reduce labor costs and improve operational stability.
Good economic benefits
The efficient digestion process enables the conversion rate of quicklime to exceed 95%. The dust recovery rate of the baghouse dust collector reaches over 99%. It can be directly converted into products, reducing the waste of raw materials.
Environmentally friendly
The entire system adopts a sealed design and is equipped with dust removal equipment. Ensure a clean and dust-free production process. Exhaust gas emissions meet national environmental protection requirements.
Calcium Hydroxide Production Line Process
- Limestone crushing and screening: Large chunks of limestone are coarsely crushed using a jaw stone crusher. Then use a hammer stone crusher to finely crush it. After crushing, use a circular vibrating screen or a linear vibrating screen to screen out uniform particles that meet the requirements. Ensure that the limestone entering the kiln has a uniform particle size.
- Calcination of limestone: Limestone of the appropriate particle size is fed into a vertical lime kiln or a limestone rotary kiln. At high temperatures of 900°C - 1200°C, limestone undergoes a decomposition reaction. This step is the core of product quality control. Precise control of calcination temperature and residence time is crucial.
- Quicklime digestion: After calcination, quicklime blocks are cooled. First, crush the material to a smaller particle size (e.g., <10mm), and then feed it into the digester through a quantitative feeder. The metered water supply system will spray a certain amount of hot water, which will react violently with quicklime. This produces highly active calcium hydroxide.
- Finished product processing: The material from the digester enters the air classifier. The qualified calcium hydroxide was separated. Calcium hydroxide powder in the baghouse dust collector is also efficiently recovered. The finished products are then stored in the finished goods warehouse. Finally, the packaging machine handles the packaging, making it easy to store and transport.
Key Equipment for Sale
—— AGICO guarantees to provide customers with high-quality original equipment.
- Core equipment: Jaw stone crusher, hammer stone crusher
The jaw stone crusher has a robust structure, strong processing capacity, and a large feed opening. Specifically designed for crushing large pieces of limestone, it can perform coarse crushing. Hammer stone crushers are used for medium and fine crushing, and can crush materials to the required fine particle size. Improve digestion efficiency.
Calcination equipment
- Core equipment: Vertical lime kiln, limestone rotary kiln
Vertical lime kilns offer high thermal efficiency, a small footprint, and excellent cost-effectiveness. It is suitable for small to medium-sized projects. Limestone rotary kiln has a high output, a high degree of automation, and high product activity. It is suitable for large-scale continuous production. The calcination equipment ensures the high activity of quicklime.
Digestive equipment
- Core equipment: Digester
The digester is the core equipment of the production line. By stirring and properly distributing water, quicklime and water can be thoroughly mixed. Quicklime is converted into calcium hydroxide. Its unique structural design ensures continuous and stable operation. The product activity can reach over 380mL.
Environmental protection equipment
- Core equipment: Baghouse dust collector
Baghouse dust collectors are used to capture dust-laden gases generated during production processes (crushing, calcination, digestion, packaging). The automatic pulse jet cleaning technology results in low resistance, low energy consumption, and a long service life for the filter bags. Dust removal efficiency >99.9%.
Integrated Production Line VS Standardized Production Line
——Two production line solutions are available for you to choose from!
Integrated Production Line
The integrated calcium hydroxide production line includes upstream limestone crushing and calcination, all the way to downstream finished calcium hydroxide packaging.
- Quality control: Control the quality of limestone and the calcination process from the source. Ensure the quicklime is highly active and has low impurities. This ensures the high purity and high activity of the calcium hydroxide product.
- Cost control: High initial investment, but low raw material costs in the long run. You need to invest in an expensive vertical lime kiln or limestone rotary kiln. However, by eliminating the intermediate step in purchasing quicklime, the cost advantage of raw materials is enormous.
- Technology management: It requires mastering two core technologies: calcination and assimilation, which place extremely high demands on the team.
- Suitable for businesses: Enterprises that own limestone mines. Large steel, calcium carbide, and chemical groups. An industry that pursues ultimate cost control and advantages across the entire industry chain.
Standardized Production Line
A standardized calcium hydroxide production line does not include lime calcination. It starts with purchasing quicklime, followed by digestion, refining, and packaging.
- Quality control: Product quality depends on the stability of the purchased quicklime. Differences in the quality of raw materials from different batches can lead to differences in the quality of the final product.
- Cost control: The initial investment is low, but the long-term raw material costs are high. No lime kiln is required, resulting in lower initial capital pressure. However, quicklime as a major cost item, is greatly affected by market price fluctuations.
- Technology management:The technology is simple; you only need to focus on digesting and refining the process.
- Suitable for businesses: A professional enterprise specializing in the deep processing of calcium hydroxide. Small and medium-sized investors or startups. Enterprises located far from mines.
