MILK OF LIME PRODUCTION

Juice Purification

Positive Pressure Kiln

Maguin's technology is based on the expertise ofFOURS DELOT Kilns, which Maguin acquired in 1995and has since been further developed.

Maguin offers coke- or anthracite-fuelled verticalkilns that were specifically developed for sugar plants,with more than 100 new kiln references in additionto a number of renovations of existing installations.

The Maguin offer includes complete installationswith milk of lime preparation station, individualequipment supply or repairs of existing lime kilnparts following an audit by our specialists. The audit may include a complete mass and heatbalance of the juice purification station.

MAIN FEATURES

Homogeneous and precise mix of combustible and stonesExcellent ergonomics of the kilnHomogeneous load distribution in the kilnPrecise and automatic milk of lime density controlClosed loop milk of lime circulationAutomatic operation control based on the consumption of the milk of lime station

ADVANTAGES

High single line capacity 15 to 400 t/d CaOHigh running flexibilityLow combustible consumption < 7% on lime stoneHigh CO2 content in the gas > 39% (pressurized kiln) Low levels of unburnt materialLong refractory life timeVery low dust emissions levelsNo hot spotsHigh level of desanding of the milk of lime

TECHNICAL DETAILS

A complete installation includes a kiln for lime calcinationand gas production, and a milk of lime preparation unit.

The process starts with the kiln load feeding in thecombustible and stone respective silos followed by precise mix preparation thanks to vibrating extractors.

The mix is then transferred by a skip to the air tight loading chamber at the top, followed by a rotary hopperfor the homogeneous load distribution into the kiln.

CO2 laden gas from the calcination is removed at thetop of the kiln, cleaned in a wet scrubber and pumpedto the juice purification station.

Lime is extracted at the bottom of the kiln by vibratingextractors (through an airtight chamber in the case ofa pressurized kiln) and further processed in the milk of lime preparation unit: lime is first mixed with waterin a friction driven slaker to produce a milk; the milk isthen desanded in a double line desanding circuit andits density is precisely and automatically adjusted in aclosed loop circuit. Milk consumption automaticallycontrols the kiln running.
