The new Ploughshare Type N
5 laboratory mixer (photo)
features a drum with a
volume of 5 L. The mixer
was conceived as a compact,
table-top model, and
comes completely assembled,
tested and thus ready for use. The
control unit is an integral part of the
housing. The speed of the mixer shaft
is infinitely adjustable. The detachable
front plate can be rotated for filling and
emptying the mixing vessel through
the same neck, which also facilitates
cleaning. A range of optional accessories
is available, including a feeding
hopper or spray lid for dosing liquid

flexibility
in tank designs, and
the blade-locking mechanism can be
accessed from outside the tank for removing
the mixer, if necessary. Retrofit
applications include side entry for
large storage tanks, or top entry when
the tank service has changed and a
new mixer is required. - Sharpe

Blending can also be performed
by this screw feeder
This new Screw Feeder (photo) is designed
to efficiently measure ingredients
and consistently deliver material
to the process. Available with
either volumetric or gravimetric controls,
the feeder features an optional
integral agitator, which enables the
feeder to effectively operate as a dry
material mixer. The unit can blend
multiple dry materials, combine thick,
wet mixes, and break up solid lumps.
The trough is available in 304 or 316
stainless steel, carbon steel, or special
