When the G-force is too low, there is insufficient energy to launch pegged and near size particles out of the apertures. Damp sticky fines can cling to the screen media surface, resulting in loss of efficiency through blinding. When the G-force is too high, the material is thrown higher and further down the screen.
The high G-force operating conditions mean that the structure of the Vibro motor console, which is a key part of vibration transmission, needs to be able to handle stress. ... but a vibrating screen machine has a lot of benefits when it comes to processing aggregate and mining materials. Vibrating screens are particularly well-suited to meet ...
