Under normal working conditions, polyurethane screen media generally do not blind during use. If this phenomenon occurs frequently,
it means that there is a problem, mainly from the following aspects:
1，Screen medias with unreasonable design or unqualified quality are selected. When customers purchase polyurethane screens,
that be better to choose vibrating screen medias products with guaranteed quality.
2，After eliminating the quality problems of the screen media, the selection of the screen media size is particularly important,
and the screen hole cannot reasonably match the diameter of the screening material. It can also lead to blinding.
3，When the mineral is too large, the mineral aggregate is easy to stick together and not easy to separate during the vibration of the screen.
Cause the hole phenomenon of polyurethane screen media. At this time, the mineral aggregate needs to be reprocessed to make the humidity reach the standard before being put into the screening equipment.
4，If the tension of the screen media is too loose or too tight, the vibration frequency and amplitude of the screen media will be insufficient,
resulting in hole blocking. The treatment method is to regularly check and adjust the tension of the polyurethane screen media in time,
and adjust it to the range of technical requirements.
