Introductoin of Calciuim hydroxide production line:
Calcium hydroxide is a traditional product of inorganic chemical industry, which is obtained by chemical reaction between calcium oxide and water. The equipment of calcium hydroxide production line mainly consists of crusher, vibrating screen, vibrating feeder, mechanical loading and unloading vertical environmental protection lime kiln, screw conveyor, box oxidizing digester (ash machine)/rotary digester, heat conducting oil heating drum continuous dryer, tail gas-air waste heat exchanger, stainless steel gas washer/PP gas washer, vibrating ash extractor, bucket elevator, etc.
Dry process flow of calcium hydroxide production line equipment:
Qualified raw lime is crushed to about 40mm by E crusher. Through bucket elevator, the lime is fed into the crushed calcium oxide storage tank. The lime in the silo is fed into the first-level lime mixer through a steady-flow screw conveyor or a quantitative weighing system. The lime is initially digested under the strong stirring of the stirring rod (divided into single, double and triple axes according to the output), and then into the second-level lime mixer (divided into single, double and triple axes according to the output) to complete digestion. Cheng.
The hydrated lime is then fed into the separator by a semi-finished screw conveyor to obtain qualified lime, which can also be graded. The refined lime is transported from the finished product to the bucket elevator and discharged into the finished product calcium hydroxide bin, and then packaged according to the user's needs. All pollution nodes of our company's environmental protection production line are completed by pulse precipitator, and the dust collection rate reaches 99.5%.
Systematic characteristics of Calcium hydroxide production line:
1. Innovative design of mixing structure: This machine adopts shear mixing with high-efficiency composite spiral curve structure. Under the action of the material, the shearing effect is produced between them to ensure the full mixing of water and material. At the same time, the blade surface is designed to have self-cleaning function when working, so as to ensure the continuous and efficient operation of the equipment.
2. Advanced PLC Control System: Advanced Auto-control Screen
3. Frequency conversion speed regulation drive system: This machine adopts frequency conversion speed regulation motor, which can automatically adjust the mixing speed and reaction time of materials with different properties. The famous brand vector frequency converter is selected for the frequency converter, which has large starting moment and stable and reliable operation.
4. Efficient and energy-saving environmental protection dust collection system: The dust collection system adopts special pulse bag filter with dust removal efficiency as high as 98%. The imported filter bag is durable and has a long service life, which ensures that the waste gas emission of enterprises meets the national environmental protection standards.
5. Superfine and efficient classification equipment: The system is equipped with air separation classifier, the fineness of finished products can be adjusted in 200-400 mesh.
6. Compact structure and high cost performance: The whole set of equipment has compact structure, small floor area, and reasonable production line process layout.
7. The ratio of lime and water is controlled by PLC and control valve, which can automatically adjust the raw materials of different properties and the finished products with different quality requirements, thus ensuring the quality of products.
