A process for the manufacture of a chemical absorbent in solid, granular form comprises mixing the components of the chemical absorbent with water to form a paste (3) and passing the paste (3) between a pair of counter-rotating, contacting rollers (1,2). The rollers (1,2) have corresponding substantially hemispherical depressions formed therein. The rollers (1,2) are synchronized such that at the point at which the surfaces of the rollers (1,2) meet spherical moulds are created from the corresponding hemispherical depressions. <IMAGE> |
