Abstract:
A method for the continuous mechanical thickening of water-containing suspensions or slurries with the aid of an endless mesh band and an endless compression surface having a closed, smooth surface moving in the direction of operation, including the steps of:compressing a suspension cake between the mesh band and the compression surface; and generating a pressure such that the mesh band wraps around the cylindrical compression surface under longitudinal tension during the dewatering process; wherein at least a second endless band (2, 3) operates on the first mesh band (1) and a water impermeable third endless band (4) is pressed against the other bands (1, 2, 3) by way of a sliding surface (5), whereby the sliding surface (5) is formed on a compression shoe (6) corresponding to the opposing compression surface (7); and the second endless band (2) is a mesh band.
