Hydrated Lime Manufacturing Proces Asia
Slaked lime (ie aging) derived by the action of water with lime, reasonable industrial processing equipment, can be processed into high-quality calcium hydroxide (commonly known as slaked lime) can be used in a variety of industries. Hydrated lime production line energy than the traditional process saving of about 15%, greatly reducing the customer's operating costs, increase economic efficiency.
Hydrated Lime Manufacturing Proces Asia
Describe the production of high calcium or dolomitic lime hydrate based on the chemical reaction is as follows:
The reaction between the lime and water to form a hydrate lime is exothermic, and in which a relatively large amount of heat is released; e.g.g., when high calcium hydrated lime from lime production, 490 Btu / lb of calcium evolution. As a point of comparison, radiating from 1000 tons of high calcium lime is equal to about 35 tons of coal moisture evolution of gross calorific value.
Hydration and digestion:
Quite often these two terms are used interchangeably; however, there is a clear and obvious differences:
Hydration: it can be defined as a process in which the amount of the reaction water and lime approximately stoichiometric, to form a product, hydrate, which is a dry powder; i.e., it is less than 1% free moisture, and as a powder deal with.
Digestive: it can be defined as a method in which an excess amount of water with lime, lime slurry to form a reaction as a liquid processing.
Storage and metering: overall system may include a silo filling line, silos, silo discharge and accurate metering equipment dry lime powder dose directly into any process.
Quicklime added: The most common method is to be stored in silos and it slaked lime dose to a tank, in which mixed with water to produce a "milk of lime" (MOL) solution.
Quicklime Maturation: The system contains advanced ball mill, jaw crusher and other crushing equipment
No pollution problem: advanced technology lime system includes features to ensure that the steam does not cause problems within, caking and build the circuit. Totally enclosed system eliminates the hazard of lime dust in the air, to maximize safety, reduce moisture into the circuit.
