MIXER DESCRIPTION
Casing - Casings are side suction, side discharge, back
pull-out designs, utilizing a spacer coupling to allow for
one craft maintenance. The alignment fit is protected
from the pumpage with a confined gasket between the
casing and the seal chamber cover.
Rotor - The fully open multi-vane rotor is supplied on all
mixers. It is engineered to effectively open and loosen
the fiber network to provide complete and efficient
chemical or gas mixing. The rotors have been designed to
handle the tough medium consistency paper stock
services. The rotor is keyed to the shaft and held in
position by a rotor locknut, sealed by a Teflon
®
O-ring
and secured with setscrews. The sleeve side of the rotor
is sealed by a Teflon
®
O-ring for a dry shaft design.
Shaft Sleeves - The sleeve is a renewable hook type,
positively driven by the rotor key. One end is free to
expand due to possible temperature variations. A Teflon
®
O-ring prevents leakage under the sleeve.
Power End - The heavy duty bearing frame and housing
are both constructed of cast iron. The frame is bolted and
rabbeted to the seal chamber. The inboard bearing
(cylindrical roller) carries radial loads only and is free to
float axially within the bearing frame. The outboard
bearing is 40° angular contact duplex set mounted
back-to-back, locked on the shaft by a threaded locknut
and carries both radial and axial loads. The frame is
sealed with labyrinth seals as standard. Flood oil
lubrication is standard. Grease lubrication is available as
an option. No special parts are required to convert from
grease to oil lubrication. Bearing frame cooling can be
supplied as an option with oil lubrication.
Seal Chamber - The seal chamber is especially designed
for medium consistency mixing applications. Its wide
open design keeps the stock flowing without dewatering
and binding the seal.
Hardware - All fasteners and tapped connections are
metric.
Direction of Rotation - Clockwise (right hand) as viewed
from the driver looking at the mixer shaft.
