The „pulverisette 1“ is a laboratory jaw crusher for the pre-crushing of hard-brittle
substances especially for the following fields of application: mining and metallurgy,
geology and mineralogy, chemistry, glass and ceramics, earths and stones.
The initial feed size is of a maximum
• of 65 mm for the type P1/I
• of 100 mm for the type P1/II
The obtainable final size - depending on the gap setting - is from about 15 mm to 2
mm.
The jaw crusher described here is a tool for use in industrial environments.
The instrument may only be used for this purpose.
2.2.1 Method of Operation
The crushing of the materials is being done within a crushing chamber consisting of
two lateral support walls (13), one settable fixed crushing plate (18) and one
movable crushing plate (22). The movable crusher jaw (21) is put into an eccentric
movement by means of a fly-wheel and a sturdy cam.
Due to its special motion sequence, the materials to be crushed are drawn into the
crushing chamber and the blockage of crushed pieces is prevented.
The material drops from the crushing chamber through the adjustable discharge
gap into the collecting vessel (12).
