Hydrated Lime Plant

Hydration Process Description

The Hydrated lime is a white dry powder having a wide range of applications both in Civil and Industrial sectors.

It is obtained by adding water to the quicklime: this process is called hydration.

The chemical reaction tacking place in the process of hydration, or quicklime slaking, is performed according to the chemical formula:

Cao    + H2o =       Ca(OH)2

The Blitzco Hydrator Type S includes the following equipment:

  • Weigh feeder
  • Duplex mixer
  • Seasoning chamber
  • Dust collector

At the Hydrator outlet the product is already a dry powder ready for the classification.

The vapors are cleaned with a dry system before discharging into atmosphere.

Technical Data

  • Capacity from: 3 TpH to 30 TpH
  • Lime & Dolomitic Lime
  • Residual moisture : < 0,8%
  • Suitable fineness for chemical and building applications
  • Fully auotmatic operation

 

AAC Plant

What is AAC?

Autoclaved Aerated Concrete, is a green precast building material present in the global market for over 70 years and is extensively used in residential, commercial and industrial construction.

AAC is an eco-friendly building material, made from natural raw materials such as: sand (or fly-ash), cement, lime, gypsum, aluminum powder and water. This mix creates an aerated concrete providing insulation, structure and fire protection in one lightweight product.

Highlights:

  • large variety of sizes
  • excellent thermal insulation
  • extreme lightweight
  • high compressive strength
  • high dimensional accuracy
  • great acoustic insulation
  • high fire resistance
  • termite resistance
  • high workability
  • Production Process

 AAC Plant (capacity 150.000 m3/y)

Lime Kiln Plant

Single shaft lime kiln

CS100

CS100 is an efficient and economic approach that can be used for lime and dolomite calcination.

The major advantages to lime/dolomite industries will include low operation and maintenance cost as well as energy consumption (eg .fuel and Electricity)

PCC Plant

 

 

 

 

 

 

 

Precipitated calcium carbonate (PCC) is an innovative product derived from lime, which has many industrial applications.

PCC is a filler used in many applications, like papers, plastics, rubbers, paints, drugs and so on.

Ground Calcium Carbonate(GCC) and Precipitated Calcium Carbonate(PCC) both are same in terms of chemical formula, CaCO3. But they differ in their manufacturing process, properties and end uses. PCC is light weight, pure, low silica than GCC.

GCC is made by just crushing, grinding and powdering the lumps.

Manufacture of PCC involves following chemical changes.

  • Calcination:Limestone is heated at about 1000-degree centigrade temperature in a Kiln to produce quick lime.

CaCO3+ Heat → CaO (Lime/quick lime) + CO2

  • Hydration/slacking:The quick lime pebbles are mixed with water in a calculated ratio to form hydrated lime slurry, called milk of lime.

2CaO + 2H2O → 2Ca(OH)2

  • Carbonation: Milk of lime slurry is then treated with CO2 evolved during calcination process and convert back to CaCO3.

Ca(OH)2 + CO2 → CaCO3 + H2O

  • Filtration and Drying: The CaCO3 formed is in slurry form (some application uses as slurry) which is then filtered and dried to powder form.

The size and shape of PCC is controlled and other impurities are removed during the process. Hence PCC has more advanced applications as compared to GCC.
