A vibrating screen feed conveying apparatus for conveying and separating sticky moisture laden bulk solids which are sticky and wet flowing onto a vibrating screening feeder and into a hopper. The apparatus includes a bed on which material is conveyed, a longitudinal counterbalance supported on a plurality of isolation springs, a plurality of inclined drive springs extending between the bed and the longitudinal counterbalance, and a plurality of stabilizers for controlling movement of the drive springs along their central axes. A plurality of vibratory motors, each having rotatable eccentric weights are attached to the rear end of the longitudinal counterbalance. The eccentric weights rotate in phase with one another to vibrate the bed at a vibration frequency.

A two-mass vibrating conveyor device is described, comprising a first mass which defines a vibrating conveyor path, a second mass which defines an equivalent vibrating conveyor path, motorization means operatively associated with the first mass and the second mass, elastic means which interconnect the first mass with the second mass, and damping means, each of the damping means being fixed at a stationary node of the elastic means. Furthermore, a vibration damper kit is described, belonging to damping means interconnecting a two-mass vibrating conveyor device to a fixed support structure.

Provided is a vibratory support device for an installation for conveying products, the device having a fixed chassis and guides mounted on the chassis that are parallel to one another and oriented in a longitudinal direction. The guides are configured as sliding supports for an endless-type belt of a conveying installation and are mounted movably with respect to the chassis with a vibratory movement in a horizontal or substantially horizontal plane. Also provided is an installation for conveying products that is equipped with a vibratory support device for supporting a portion of the length of its conveyor belt.
