How is calcium hydroxide produced
Price:
Calcium hydroxide,as an important inorganic compound,has indispensable applications in many fields such as construction,environmental protection,chemical industry,agriculture,etc.Calcium hydroxide is produced using a calcium hydroxide production line,a complete production line that converts raw materials into high-quality calcium hydroxide products through a series of process flows and advanced equipment.
The main raw material for the production of calcium hydroxide is limestone,which directly affects the quality of the product.Excellent limestone should have a high content of calcium carbonate,usually requiring a calcium carbonate content of over 90%.At the same time,the content of impurities such as silica,alumina,iron oxide,etc.should be controlled,as these impurities may affect the activity,purity,and whiteness of calcium hydroxide.
Calcium hydroxide equipment
The selected limestone needs to be crushed and screened.Firstly,a jaw crusher is used to crush large limestone into smaller particles,typically ranging from 100-300mm in size.Then,the crushed limestone is sieved through a vibrating screen to remove particles that do not meet the particle size requirements,ensuring that the limestone entering the next process has uniform particle size and meets the calcination requirements.The suitable particle size range is usually between 50-150mm.
Calcination is a key process in the production of calcium hydroxide,and commonly used equipment includes vertical kilns and rotary kilns.Vertical kiln is a traditional calcination equipment with a simple structure and low investment cost,but relatively low thermal efficiency and limited production capacity,suitable for small-scale production.Rotary kilns have the advantages of high production capacity,high thermal efficiency,and uniform product quality.They can control the calcination process and are the primary equipment for large-scale production of calcium hydroxide.
The quicklime from the lime kiln enters the digester for digestion reaction.Common digestive systems include trough digesters and rotary digesters.The trough digester has a simple structure and easy operation,but the digestion time is relatively long and the digestion effect is not very uniform;Rotary digesters have the advantages of fast digestion speed and even digestion,which can better control the reaction process and improve product quality.
Calcium hydroxide equipment
在消化器中，将适量的水加入生石灰中，生石灰与水发生剧烈的放热反应，生成氢氧化钙。加水量的多少是影响产品质量的重要因素之一，一般生石灰与水的质量比为1：3-1：5。加水量不足，生石灰不能完全消化，产品中会残留大量生石灰，影响产品的纯度和活性；加水量过多，会导致氢氧化钙浆液过稀，增加后续脱水成本。
由于消化反应放出大量的热，导致反应温度升高，过高的温度会影响氢氧化钙的结晶过程，造成产品颗粒粗大，活性降低。因此，消化过程中需要采取适当的冷却措施，如采用夹套冷却或外循环冷却，控制反应温度在60-80℃。同时需要控制消化时间，一般为15-30分钟，以保证生石灰充分消化。
粉碎后的氢氧化钙粉采用自动包装机进行包装，通常采用塑料编织袋或纸袋包装，包装规格根据客户需求而定，常见的有25kg/袋、50kg/袋等，包装过程中需确保包装密封严密，
氢氧化钙生产过程中涉及高温、高压、强碱性物质，存在一定的安全风险，因此需要为生产人员配备必要的个人防护装备，如安全护目镜、防护手套、防护服等，同时在生产现场设置明显的安全警示标志，加强对生产人员的安全培训，增强安全意识，确保生产过程安全运行。
氢氧化钙生产工艺
一条完整的氢氧化钙生产线经过原料准备、石灰石煅烧、生石灰消化、产品后处理以及环保安全措施等一系列工序，将石灰石转化为高品质的氢氧化钙产品。随着技术的不断进步和环保要求的不断提高，氢氧化钙生产线也在不断优化升级，提高生产效率、产品质量和环保水平。
