Courtoy tablet presses are fitted with a powder in-feed system which ensures minimal weight variability, even at high speeds and with poorly flowing formulations
A combination of a specially designed rotary valve and powder level sensor allows for accurate control of the powder column above the feeder. This "constant level" systems allows for a reduced and constant powder pressure inside the rotary feeder - eliminates risk of feeder jamming and guarantees constant powder feed flow into the dies, even at very high compression speeds.
All Courtoy presses can be supplied with the "constant level" rotary feeding system:
| Constant level - MODUL™ series |
Constant level - R series |
Alternatively, a vertical agitator system can be installed for powders with extremely poor flow characteristics.
Two-chamber paddle feeder
A standard feature on all Courtoy presses is the two-chamber paddle feeder, with independent frequency controller and drive motor for each paddle. The paddle speeds are memorised as product recipe parameters in the control system.
This design offers the ultimate set-up flexibility to find the optimal feeding conditions for a wide range of products. As a result, higher machine speeds can be achieved than on other tablet presses with the same number of punch positions.
The simple construction inside the feeder, with no drive belts, gears or bearings, makes it light-weight and easy to clean. It can be immersed in water or washed in a washing machine.
Maximum flexibility to find the optimal feeding parameters for a wide range of powders with different flow characteristics.
