Automatic Tensioning Screen Frames
Replacing wood screen frames with all-metal automatic tensioning screen
frames improves efficiency, speed, repeatability, and cleanliness. These frames
feature a patented design for
attaching screen clothing to
unitized frames with Quick-
Snap spring tension clips. The
clips permit quick removal and
replacement of screen clothing
and ensure constant, uniform
tension across the entire screen
surface for superior screening,
reduced screen blinding, and
longer screen life. With a one-
piece design, the screen frames
are easy to assemble, clean, and
maintain, simplifying mainte-
nance, reducing downtime, and eliminating the need for spare screen frames.

Deblinding System

The Vibrasonic Spiroscreen allows powders to be screened using finer meshes
with greater accuracy than was possible with previous models. This feature
increases the value of the screened powders while improving their final qual-
ity. The unit eliminates screen blinding and increases throughput when sieving
pharmaceuticals, metal powders, foods,

and other materials. The system uses a spiral-shaped ultrasonic distribution element to provide maximum control of the powder on the mesh screen. All screen apertures remain clear so that powder can pass through them, reducing production downtime. The Spiroscreen fits any existing circular sieve or screener, even other companies’ models.

Don’t take a chance on
machinery failure.
With rugged and reliable
speed monitoring systems
from Electro-Sensors, you can spot
problems in shaft-driven components
before things take a turn for the worse.
And that can save you a small fortune.
The original digital speed switch.
We pioneered machine monitoring over 35 years ago, and our
field-proven technology is still the most durable and reliable—even
in extreme conditions. With the largest, most forgiving gap and
alignment tolerances, we can help prevent damage to conveyors,
elevators, and other shaft driven components caused by overload
or slippage before it can occur. And now our systems are even
easier to install.

We find trouble before trouble finds you.
