3 models are available:
• The HZ BIROL is an horizontal screen or with low slope. It is moved by a rectilinear inclined vibration that makes the products moving forward with successive bounces.
Two motor-vibrator equipped with adjustable counterweights at each end of the rotor, are attached directly to the device. They are positioned so that, rotating in opposite direction, they self-synchronize to generate a linear vibratory movement.
• The EV BIROL is an inclined screen ROL type having a greater lengh to allow the product to stay longer on the grid.
The mechanism is mounted above the vibrating part and may be moved longitudinally.
• The AZ BIROL is a screen designed to handle products consisting of grains of suare or round shape such as plastic pellets.
The flat granules progress horizontally on the grid, avoiding the long elements to get stuck into the mesh openings.
