The idea of segmented screens is based on dividing the screening surface into one round central segment and 6 to 8 outer segments like the segments of an orange. The bouncing ball cleaning system is also segmented so that screening inserts segmented in this way can operate effectively. Segmented screening inserts are protected by international patents.
Reduction in spare part costs
Segmenting the screen frames has a particularly advantageous effect in larger tumbler screening machines in terms of operating, maintenance and spare parts costs: If there is a screen tear, it is no longer necessary to replace the entire screening insert, but only the segment affected.
The smaller screen segments can withstand significantly higher loadings, and therefore achieve significantly longer service lives.
In the past, changing large screens used to require several people. Changing a screen segment is something that can be done by one person, and the downtime of a screening machine is reduced significantly. The sequence of benefits is added to by easier storage and less expensive transport of the smaller individual segments.
