Abstract:
A disk filter for filtering mat forming suspensions is provided with a hollow shaft for receiving a flow of fine fraction created by hydrostatic pressure difference between the suspension to be filtered and the fine fraction in the hollow shaft. According to the invention, each disc is provided with a number of fine fraction chambers communicating with the interior of the hollow shaft via respective holes in the circumferential wall of the shaft. Each chamber is arranged, such that it functions as a dropleg during movement upwards, with the result that the coarse particle (fibre) concentration of the created coarse fraction is increased.
