Anhui magnesium hydroxide production line

Advantages and principles of our three digesters are the following: 1. The ability to control CaO in the digester digestion reaction time, can reach 15 to 20 minutes of requirements, so that CaO fully digest. 2. The digester has good insulation properties, the unique design of the large amount of heat generated during the reaction of CaO conversion internal use in the digester, improve the internal temperature reaches about 60 degrees for 3-5 minutes, it is conducive to fully digest the CaO. 3. Feeding process control: After a propeller, the desired level of material fed into the digestion compartment. Advantages: CaO prevent contact with water instantly generate a lot of hot steam and dust reflux into the screw feeder weigher, affect the accuracy of the sensor signal. The three water distribution digestion: water distribution by hierarchical scientific way to make CaO full pre-digested through CaO and rational water ratio, in a later stage digestion, into the secondary digestion reaction process. In this case, the secondary digestion in vivo release of heat CaO and speed of digestion is the best time. In the secondary digestion when entering the tertiary digestion, CaO after digestion has entered the dry state. Finally, after three to really digest the CaO into fluffy powder, the whole digestive process about 15 to 20 minutes. Third, the device advantages of the device according to the environmental requirements, supporting the dust removal device, solving the problem of pollution hot steam and dust produced during the digestion of lime. At the same time, supporting the follow-up process equipment, such as lime pulp machine, pulp residue from the machine and filters, etc., prepared to meet the demand for high-purity concentration lime emulsion. Fourth, the parameters required Yield: 3-65 tons / hour effective calcium conversion rate: 95% dust emission concentration: ≤30mg / m3 (GB) Standard consumption (95% lime content, lime consumption: 0.75 tons / ton lime) water: 0.5m3 / tonne lime power consumption: 2.6kwh / tonne lime BET specific surface area: 18 +/- 2 residual moisture: ≦ 1 product fineness: 200 mesh sieve-pass filter 65% (effective calcium content of more than 85%) Purity: upgrade calcium content of 3-5 points
