IKA® heavy-duty horizontal kneading machines of type HKD and HKS are twin bowl
kneading machines with horizontally arranged kneading shafts which are differing
in their kneading tools.
The HKD is equipped with DUPLEX kneading blades, deeply intermeshing and stripping
each other. The different speed of the kneading blades (speed ratio 2 : 1) causes
the kneading blade surfaces to alternately move towards and away from each other.
This results in high pressure-, tensile- and shear forces and thus in high friction
within the kneading product which cares for excellent dispersing and homogeneity.
The HKS is equipped with 2 Z-kneading blades which distinguish by left-hand
and right-hand twisting. This twisting of the Z-blades causes continuous movement
of the material from the kneading bowl walls to its centre or vice versa, depending
on the direction of rotation. The different speed of the counter rotating kneading
shafts (speed ratio 5 : 3) creates high pressure and shear forces resulting
in an intensive mixing. Drive systems
Kneading drive
- geared motor: kneading blades with one fixed speed
- pole-changeable geared motor: choice between two fixed speeds
- geared motor with frequency converter: speeds can infinitely be adjusted
via frequency converter
These 3 drive systems are also offered in Ex-protected design. The frequency
converter itself is not Ex-protected and has always to be installed outside
the hazardous area.
- hydraulic drive: infinitely adjustable speeds, Ex-protected
Discharge screw
- pole-changeable geared motor: choice between two fixed speeds
- geared motor with frequency converter: speeds can infinitely be adjusted
via frequency converter
These 2 drive systems are also offered in Ex-protected design. The frequency
converter itself is not Ex-protected and has always to be installed outside
the hazardous area.
- hydraulic drive: infinitely adjustable speeds, Ex-protected
Options
For our horizontal kneading machines we offer a great number of helpful options,
e.g.: ·
- discharge screws
- removable side wall for easier cleaning of the kneading tools, the bowl
and the discharges screw
