Title:

METHOD FOR MANUFACTURING LIME CAKE GRANULATED DRY PRODUCT

Document Type and Number:

Japanese Patent JP2002331300

Kind Code:

A

Abstract:

To provide a method for manufacturing a lime cake granulated dry product having good granulation properties and yield and suitably used for fertilizer or the like by lowering the water content of a hydrated line cake generated in large quantities in a sugar manufacturing factory by a simple technique before granulating the lime cake.

A dry powder is added to the hydrated lime cake generated in the sugar manufacturing factory to lower the moisture content of the lime cake to adjust the same to 25-30 wt.%. The obtained moisture content adjusted lime cake is subjected to extrusion granulation using a screen with a die diameter of 2.0-4.0 mm and the granulated cake is dried at 80-200°C after granulation to manufacture the dehydrated lime cake granulated dry product.
