Calcination of calcium carbonate to produce calcium oxide gas suspension calcination process is a new process of calcium carbonate calcination. Calcium carbonate powder is ground into a powder of <125 mesh, and then enters the gas suspension calcination to generate calcium oxide after a few seconds of pyrolysis. Due to rapid calcination and uniform heat transfer, it is an advanced process for producing activated calcium oxide, and it is also an advanced process for decomposing caustic lime.
Calcium Carbonate Calciner Introduction:
A type of furnace that uses hot air to calcine powdery materials. It is mainly composed of preheating dryer, heat exchanger, calcining and decomposition furnace, trap, heat source and so on. The material can be quickly decomposed within a few seconds after entering the furnace. Because the powdery material is calcined, the calcined material is uniform, there is no raw burning and over-burning, and the calcining temperature can be accurately controlled.
The working principle of calcium carbonate calciner:
The material or mud cake-like calcium carbonate and calcium hydroxide are fed into the dryer or preheating machine, and the waste heat air produced by the calciner decomposition furnace to decompose calcium carbonate is used as the above-mentioned drying heat source. The dried calcium carbonate is sent to the calciner for calcination, and the decomposed calcium oxide is discharged from the discharge port.
Performance characteristics of calcium carbonate calciner:
1. The calcined material is uniform and sufficient, which can produce activated calcium oxide.
2. The equipment system is pollution-free and meets environmental protection requirements.
3. Compared with the shaft kiln, the energy consumption can be saved by 20-30%.
4. It is easy to operate and has a high degree of automation.
Calcium Carbonate Calciner Technical Specifications:
Annual output of sets within the range of series specifications: 20,000 tons, 50,000 tons, 100,000 tons, 150,000 tons, 200,000 tons
The use of activated calcium oxide:
Activated calcium oxide, also known as effective calcium oxide, refers to calcium oxide, which is obtained by decomposing calcium carbonate. It has hydration activity and can react with acidic oxides. Also known as superfine calcium carbonate, the standard name is superfine calcium carbonate. This is the main indicator of lime quality. Activated calcium oxide is refined by advanced technology and selected materials, and has the characteristics of high purity. This activated calcium oxide is widely used in the chemical industry and is an ideal filling material for adhesives and other industries.
1. The mature industry of activated calcium oxide is the plastics industry. (1)The plastisol used in the interior sealing of automobiles can improve the rheology of the plastic masterbatch and improve its formability. (2)As a plastic filler, it has the effect of toughening and strengthening, improving the bending strength, bending elastic modulus, heat distortion temperature and dimensional stability of plastics, and also endows plastics with heat retention.
2. activated calcium oxide is used in ink products, showing excellent dispersion, transparency, excellent gloss, excellent ink absorption and high drying. As an ink filler in resin ink, activated calcium oxide has the advantages of good stability, high gloss, no influence on ink drying performance, and strong adaptability.
3. the paper industry is a market with great development potential for activated calcium oxide. Activated calcium oxide is also mainly used in special paper products, such as feminine sanitary napkins, baby diapers, etc. Ultrafine calcium carbonate as a paper filler has the following advantages: high shading and brightness, which can improve the whiteness and shading of paper products; high expandability, activated calcium oxide can enable paper mills to use more fillers, greatly reducing raw material costs; small and uniform particle size, more uniform and smooth products; high oil absorption value can improve the pigment fastness of colored paper.
4. As a pigment and filler in the coating industry, activated calcium oxide has the advantages of fineness, uniformity, high whiteness, and good optical properties. Nano-calcium carbonate can suspend high-density lithopone in the formulation and play an anti-sedimentation role in paint making. After the paint is made, the whiteness of the paint film increases and the gloss is high, but the hiding power does not decrease.
5. The rubber industry is one of the main application markets of activated calcium oxide. Compared with ordinary calcium carbonate, rubber containing activated calcium oxide has higher elongation, tear performance, compression set and buckling resistance. After adding activated calcium oxide and treating it with resin acid, the tear strength of some rubber products increased by more than 4 times.
6. Activated calcium oxide can be used as a calcium supplement in the feed industry to increase the calcium content of the feed.
7. Used in cosmetics, because of its high purity, good whiteness and fine particle size, it can replace titanium dioxide.
