METHOD AND MULTI-DECK SCREENER FOR DETERMINING THE INDIVIDUAL PARTICLE SIZE CLASSES OF A MATERIAL SAMPLE
The invention relates to a method for determining the individual particle size classes of a material sample using a multi-deck screener (1) having a plurality of screens arranged one above the other with downwardly decreasing hole size of the screens for separation of the particle size classes. Once the material sample has been applied to the uppermost screen for the duration of a first definable time period and/or until the end of the separation of the particle size classes has been detected, a classification phase is performed in order to separate the particle size classes and then a transport phase is performed for the duration of a second definable time period in order to transport away the material sample separated in accordance with particle size classes to individual collection containers associated with the particle sizes. The screens of the multi-deck screener (1) are excited to vibrate during the classification phase and during the transport phase, the screens being excited to vibrate, during the transport phase, at an angle relative to the vertical, such that the throwing movement resulting from the vibration excitation has a component in the direction of an outlet of the screens arranged at the end face of each screen. The invention further relates to a multi-deck screener (1) for carrying out the method.

For fastening of a screen lining segment (10, 20) and/or of an anti-wear element at least one adapter (30) is fastened to the frame (40), the adapter (30) having at least one magnet (31, 32). The magnet interacts with the frame (40) and/or with at least one ferromagnetic coupling element (11, 21) arranged in a vibration-proof manner in or on the screen lining segment (10, 20) and/or anti-wear element and in this way produces a magnetic connection between the adapter (30) and the frame (40) and/or between the adapter (30) and the screen lining segment (10, 20) and/or anti-wear element. The invention further relates to a screening machine having such a fastening system.
