Screw Feeder TTS and TRS
Conveying and load-dependent product dosing
- Bridges conveyor distances between pre-hoppers and mills
- For products with poor flow properties
- Load-dependent dosing
- Ideal complement to the air-gravity separators AGS & AGS AD
Optimum Dosing of the Feed Material
The screw feeder is suitable for conveying and load dependent feeding of free-flowing bulk materials to the hammer mill. A reduced thread in the inlet and a double thread in the outlet ensure an optimal and continuous product flow. The trough is designed either as an U-through (TTS) or as a pipe (TRS). The standard series includes 6 different screw types, some in double screw arrangement. The trough length is 2000 mm. In addition, a large number of special designs (screw diameter, number of troughs, length, installation position, drive) are possible in order to individually adapt the screw to the installation situation.
Take Advantage of these Benefits
- Precise, Load-dependent feeding of the hammer mill in combination with a controlled frequency converter
- Intake thread with reduced pitch for better discharge of the
material from a pre-hopper - Double thread in the outlet area with scrapers to equalize the product flow onto the mill
- Standard trough length 2000 mm
- 4 different screw diameters
- Design as single, twin, or triple screw
- Adaptable to the individual installation situation: special designs
possible (diameter, thread design, number of troughs, length,
arrangement, drive, wear protection)
- Robust welded steel construction for continuous industrial
operation (24/7) - Continuously welded screw thread on both sides
- Double Simmerring seal on both sides
- Pressure shock resistant and flameproof design (0.4 bar) optionally possible
- ATEX design according to zone 21 (II 2 D) inside and zone 22
(II 3 D) outside optionally possible
