Material lock with subdivided resettable sealing plates

摘要

In the case of a material lock, the sealing plates are divided in the circumferential direction into two regions (6, 7 and/or 8, 9) which are sealed off (11) from one another. This ensures that when the inside (3) and outside (4) of the cellular cylinder wall are subjected to different levels of wear, the sealing plate can be adapted to this and can be reset by different amounts. To ensure that the radial spokes (5) of the cellular casing (2), which are not subjected to a high degree of wear per se, do not tend to have a supporting action and prevent resetting of the outer sealing plates (6, 7), the said spokes (5) have points which are intended to be subjected to wear, which take the form of lips (14) in this case. <IMAGE>
