Calcium hydroxide equipment: 3 Critical dimensions teach you to choose the right equipment of different sizes
Small-scale calcium hydroxide equipment:
It occupies a small area, has limited processing capacity, and can produce only a few tons per hour, which can meet the needs of small enterprises or laboratories. Its process flow is simple, including raw material crushing, digestion, desulfurization, dehydration and other steps. The raw materials are crushed by a small jaw crusher, and then digested, desulfurized and dehydrated to obtain the product.
Large-scale calcium hydroxide equipment:
It occupies a large area, has strong processing capacity, and can produce tens or even hundreds of tons per hour. Its process flow is more complex and meticulous. Besides the basic steps of small-scale equipment, there may be multi-level reactions after the digestion stage. The separation stage adopts efficient separation technology and is also equipped with an advanced automatic control system.
Differences in the selection of calcium hydroxide equipment
Small-scale calcium hydroxide equipment:
Pursuing simplicity and efficiency, adopting standardized configuration, easy to purchase and replace, reducing costs and maintenance difficulty. Small jaw crushers and ball mills are commonly used in the raw material crushing and grinding process. Although they are compact, they are highly efficient in small-scale production. The operation and maintenance are simple. Operators do not need much professional training. Daily maintenance is easy, but safety issues should be noted. Safety operation procedures should be followed, protective equipment should be worn, and regular safety inspections should be conducted. Less investment is made in safety and environmental protection, and the protective measures are basic. Safety protection is only equipped with basic facilities, and the electrical part is routinely grounded for protection. The environmental protection measures are simple. Small bag filters are used for dust treatment and simple sedimentation tanks are set up for wastewater treatment, which are difficult to meet the environmental protection requirements.
Large-scale calcium hydroxide equipment:
To meet the demands of large-scale production, the configuration needs to be customized and designed. Large rotary kilns are often selected for the digestion stage, while large filter presses are used for the dehydration stage. The material and performance of the equipment are carefully selected. The parts in contact with the materials are made of corrosion-resistant and wear-resistant materials, and the performance is meticulously tuned. Operation and maintenance require professional skills and experience. Operators need to undergo strict training, be familiar with the equipment structure and operation procedures, and precisely control process parameters during operation. Daily maintenance and upkeep are of great importance. A comprehensive inspection, replacement of components, and cleaning, lubrication and anti-corrosion should be carried out. It has made significant investments in safety and environmental protection, and has a complete protection system. Advanced environmental protection measures are adopted. Desulfurization, denitrification and dust removal equipment are used for waste gas treatment. A complete system is established for wastewater treatment, and the wastewater is discharged up to standard or recycled.
Conclusion
Both small and large calcium hydroxide equipment have their own advantages. Small equipment is compact, flexible and has a low investment cost, making it suitable for small enterprises and laboratories. Large-scale equipment has strong processing capacity, high production efficiency, and complete safety and environmental protection measures, making it suitable for large-scale production enterprises. When choosing equipment, enterprises need to comprehensively consider factors such as production demands, site conditions, and economic strength to ensure the selection of the most suitable equipment and maximize production benefits.
