TABLET PRESS
1.2.5 Method of operation
The pellet press is a manually-operated hydraulic press. The device is fitted
with a piston pump. This has a suction and pressure valve, a pressure limiting
and stop valve. The pressure limiting valve is set for a maximum oil pressure of
350 bar, and may not be adjusted. The stop valve must be closed before the
pressing process. The hydraulic oil is kept in an oil reservoir. This is closed off
using a locking screw (9) with an integrated vent screw. The screw is used for
filling and automatic venting of the oil reservoir. It prevents a vacuum being
created inside. The locking screw (9) is protected by a plastic ring. The
workspace is surrounded by a Plexiglas jacket. There is a door with handle at
the front of the jacket. The pressure cylinder piston (6) is located in the centre
of the workspace. It is protected by a pressure plate (6a). A spindle (4) with
hand wheel (3) is used to create the counterpressure and to clamp the pressing
tool. A pressure gauge (7), which displays the pressure during the pressing
process, is located at the front of the housing.
