Standard vibrating screen, that is, inclined screen, is the most preferred classification equipment in crushing and screening processes, which is positioned inclined on a strong and high-strength chassis and performs vibration movement on springs that can absorb the determined load.
INCLINED SCREEN
Inclined screens are very important for all mineral processes. The process of grouping the bulk material containing pieces of different sizes in at least two size ranges is called screening. The screening process is referred to as the “classification process” in mineral processes.
Screening panels with specific sizes of mesh are attached to the sieve body. While the fed material moves on the sieve panel with the vibration of the body, the pieces smaller than the mesh gap pass to a lower sieve panel with a smaller mesh size to be screened again.
DESIGN
Inclined sieves are the most used equipment for the grading process. It consists of sieve body, drive mechanism and elastic system. The body houses the drive mechanism and screening panels.
Screening panels are tautly connected to structures called screen casings. The sieve cases are designed to give the panels a herringbone shape. The frames also provide the rigidity of the body.
The drive mechanism is the most important part of the sieve. The centrifugal force created by the rotation of the eccentric weights connected to the two ends of the sieve shaft at a certain speed ensures that the sieve body makes a continuous reciprocating motion on the elastic system. Thanks to this oscillating movement, that is, the vibration movement, the material is provided to move on the panel.
