Abstract
An appliance for fragmenting heterogeneous elements of a fluid medium comprising a filter module with an inlet connected to a supply line for the fluid medium including heterogeneous elements and an outlet connected to a fluid medium outlet line. The filter module comprises a series of channels inside which the fluid medium is to be circulated. The appliance further comprises a planar fragmentation device which is located upstream of the inlet and comprises passages. In accordance with the invention, the planar device constitutes a screen comprising passages which have one dimension equal to the smallest dimension of the cross section of flow of the channels divided by n, where n is in the range 1.4 to 10. The passages are formed from cutting separator elements which define the passages and have a minimum thickness in the range 0.1 mm to 2 mm to ensure fragmentation of heterogeneous elements of the fluid medium.
