Strong-Mate Mixer
Drawing #386000620
The Strong-Mate Mixer is a completely innovative idea in mixers, designed for mixing most varieties of
cementitious materials. The mixer is designed to give a maximum amount of agitation, and complete
dispersement of the particulate ingredients and admixtures in as short a mixing cycle as is possible.
To accomplish this, two inter-connected fixed drums are attached and include two self-wiping, ribbon
paddles that counter-rotate. The mix is brought to the center where it gets an EXTRA ORDINARY and
VIOLENT mixing action – but does not “beat” the mix as is the case with the conventional type paddle
mixers. The amount of mixing time to bring the mixture into a completely homogenous mix under
normal conditions is about 30 seconds. With longer mixing times the yield of a mix can actually be
increased over 100%.
The mixer should be thoroughly cleaned after each day’s use to prevent a buildup of materials on blades
and walls of the mixer. Power is supplied to the mixing paddles by a 5 horsepower, 3 phase, A.C. electric
motor.
The mixer has a set of packing chambers with rings of packing at either end of the paddle blade shafts to
prevent water and the mix from getting into the flange bearings. One fitting, on each of the flange
bearings, is for greasing the seals inside.
THESE FITTINGS ARE LOCATED ON TOP OF THE
BEARING HOUSING AND MARKED “GREASE TWICE DAILY”.
These should be greased every
four hours of operation and at the end of each day’s operation. Enough grease is injected to show at the
end of the packing house inside the mixer after the cleanup operation. This ensures that any materials that
have worked past the seals is discharged out and cannot harden inside and prevent the sealing action
necessary to protect the shaft bearing.
Grease the fittings on the sides of the bearing housing every 150 hours of operation. These fittings are
provided for greasing the race of the bearings which are prepacked at the factory. Too much grease here
can shorten the life of the bearing more than not greasing it at all.
Caution:
Do not remove mixer guard or put hand in mixer at any time without disconnecting electrical
power and locking it in the off position. When cleaning mixer at end of day’s operation and washing out
loose materials removed during cleanup. Replace the mixer inlet grate before reconnecting power.
Failure to do so could result in severe bodily injury.
