BRITANNIA Company offer high precision Roll Mills to
permit the soap manufacturer to adjust the structure of
the crystalline soap particles so that the soap feels
creamy and smooth to the human skin.
The Britannia range of Mills are constructed in 3 and 5
roll versions, in a variety of sizes.
They are massively constructed machines fitted with
precision ground rollers capable of making the soap
perfectly homogenous and completely incorporating
colours, perfumes, additives and fillers into the soap
Britannia Roll Mill uses massively thick high carbon
steel rolls mounted between machined steel side plates.
The rolls are a computer produced design combining
strength and thermal efficiency.
A particular feature of the Britannia rolls is their
modular assembly. This allows for roller shell
replacement after extended use. Other designs require
complete roll replacement. The removable end plates
permit Britannia to machine the inside of the roll shell
guaranteeing even heat transfer during soap processing.
A substantial amount of experimental work has been
carried out to ensure turbulence is created within the
recirculating coolant inside the rolls. Trials have
shown that this is essential in order to attain maximum
Accordingly special design features have been
incorporated to control the quantity and flow rate of
The rolls are supported in heavy duty spherical roller
bearings which are lubricated by grease nipples located
on the outside of the machine. The bearings are fitted
in an eccentric housing, which when rotated by external
handwheels, adjusts the roll gap. In this way, the soap
ribbon exiting from the rolls, can be adjusted for
thickness during running operation, to give optimum
The rolls all rotate at slightly different speeds and
this exerts a shearing action on the soap mass. The
rollers are driven by a large electric motor through
massive spur gears. An automatic oil distribution system
ensures the gears are continually lubricated during
operation. Sensors prevent the machine operating if the
lubrication system fails.
The roll adjustment mechanisms are fitted with
individual digital indicators and separate thermometers
monitor the temperature of each roll. Hand valves are
provided to permit the independent adjustment of
temperature on each roll. A stainless steel catch tray
is provided under the rolls to make cleaning easy. The
roll mill is fitted with substantial steel guards which
are easily removable for servicing.
