CDU PG01 Container Discharge Unit
Images marked “Installation visualization” are 3D renderings. Final configuration is confirmed for each project.
A wide inlet and opposing screw flights collect powders and granules toward a central outlet, with particular advantages for poorly flowing powders with a high angle of repose.
Design data
- Capacity
- Selected for the material and conveying conditions
- Container tilt angle
- Defined by the material, liner and vehicle
CDU PG01 combines a wide receiving opening with opposing screw flights. The arrangement accommodates a large opening at the bottom of the container liner, while the screw collects material inward from both sides toward the central outlet. This active collection offers particular advantages for poorly flowing powders with a high angle of repose, and also handles granules. Liner openings, clamping interfaces and downstream conveying are configured for the application.
Features
- Wide receiving opening accommodates a large bottom opening in the liner
- Opposing screw flights collect material from both sides toward the central outlet
- For powders and granules, with particular advantages for poorly flowing powders with a high angle of repose
- Stainless-steel screw and housing, with polished contact surfaces and a brushed housing exterior
Applications
- Container unloading applications for PE/PP and other plastic powders and granules
- Powder applications with a high angle of repose and poor flowability that benefit from active collection
Configuration process
Define the material and duty
Match liner and receiving interfaces
Define downstream conveying
Configure controls and installation
Choosing a CDU model
Six configurations for different discharge requirements: start with flow behavior, then match the liner interface and installation arrangement.
| Model | Arrangement | Material focus | Receiving concept |
|---|---|---|---|
| PG01 | Container-mounted | Powders and granules; poor-flow powders | Wide inlet, opposing flights |
| PG02 | Container-mounted | Free-flowing powders and granules | Frame-mounted receiving unit |
| PG03 | Container-mounted | Caking, poorly flowing bulk solids | Access panels, central discharge |
| PG04 | Mobile | Free-flowing powders and granules | Wide fishtail inlet |
| PG05 | Mobile | Free-flowing bulk solids | Three liner connections |
| PG06 | Mobile | Free-flowing granules | Round inlet, rotary valve |
This comparison supports initial selection. Final configuration depends on material trials, liner dimensions and conveying conditions.
Information for selection
These inputs help match the receiving interface, discharge assembly and downstream conveying system.
| Category | Information to provide |
|---|---|
| Material | Name, powder or granule, particle size and bulk density |
| Flow behavior | Angle of repose, caking or bridging tendency, moisture |
| Duty | Target throughput, operating temperature, batches and duty |
| Container liner | Outlet count, shape, dimensions, location and attachment |
| Container and site | Container type, available tilt angle, space and equipment layout |
| Downstream conveying | Conveying method, distance, lift, pipe size and receiving conditions |
| Utilities and controls | Power supply, compressed air, interlocks and site interfaces |
Throughput, tilt angle, materials and connection dimensions are confirmed for the application.
