ABSTRACT:
Initially moist metal hydroxide sludge is formed into a suitable mass, such as sludge cakes (2) which are fed downwardly in a hopper (1) and pressed into the cells (7) of a multi-cellular moving metal belt (5) in a two-stage process. The first stage deposits the sludge roughly into the cells, while the second stage compresses and compacts the deposited sludge tightly into the cells so that the sludge is in intimate contact with the cell walls throughout each cell. The sludge-filled belt is passed through a dryer (3) whereby the belt is subject to indirect, rather than direct, heating. More particularly, the belt passes through an enclosed muffle (21) and is caused to be in direct heat-exchanging contact with the bottom muffle wall (23). The latter wall is heated from beneath and outside the muffle chamber, as by heated air jets. The heat from this wall is not only conducted into the bottom of the sludge passing thereacross, but also into the cell walls of the metal belt itself and hence to the sides of the sludge pieces.
