Document Type and Number:
Japanese Patent JPH11217576
Kind Code:
A
Abstract:
To obtain a co-fuel for cement calcination by effectively recycling water-containing organic sludge and to provide a method for simply and economically producing this fuel.
This co-fuel for cement calcination is in the form of granules having a water content of ≤10 wt.% and a diameter of 0.1-10 mm, obtained by granulating and drying a water-containing organic sludge, such as sewage sludge, the residual sludge from food processing or sludge from paper manufacturing. The co-fuel is produced by dehydrating a water-containing organic sludge to yield an organic dehydrated cake, mixing and granulating the cake by use of a two-shaft mixer followed by drying in a hot-air parallel-stream rotary drying drum.
