Fig. 1: Diagram of grinding
The grinding process in this machine takes place using pressure.
The grinding chamber (T) is funnel-shaped and narrows to the outlet opening (TA)
depending on the set gap width.
The gap width setting is infinitely adjustable.
The machine has a stationary crusher arm (RB) connected to the gap width
adjustment (D) and a mobile crusher arm (SB). Replaceable breaking jaws are
attached to both crusher arms, between which the grinding takes place by means
of pressure.
The eccentric movement of the actuated crusher arm (550...950/min) produces a
constant conveying of the grinding material until the final fineness has been
achieved that enables it to pass through the set gap (TA). It is then collected in a
removable collecting receptacle (E).
The convex shape of the replaceable breaking jaws made from different materials
ensures the best possible fine grinding and at the same time prevents material
compaction and a bridging effect.
