Since its introduction
three decades ago,
the SPEX SamplePrep
Shatterbox® has become
the most popular
“swing mill” in America.
It remains the most
efficient way to pulverize
up to 100 grams of brittle material to analytical
fineness. Shatterboxes
typically grind cement,
rocks, slags, soils,
ceramics, and ores,
but have been used
for hundreds of other
materials including
sulfur pellets, dried
marsh-grass, and
pharmaceuticals. Both mills
are CE compliant.
Programmable, Portable, and Safe
This enclosed, advanced design features the ease
of use of a cam-action clamp. The clamp bar is
held down securely by a cam-activated lever. The
electronic controls allow programmed running
times up to 10 minutes. As the Shatterbox runs,
the timer display counts down the minutes and
seconds remaining. A “pause” function allows
interruption of a grinding cycle.
Safety features include a safety interlock and gas
cylinders for the lid. The interlock holds the lid
closed whenever the mill is running, and the
cylinders control movement of the lid when it
is opened or closed. The sound-insulated steel
cabinet has a cooling fan to prevent the
motor from overheating and lockable casters with which the mill can be moved about
the lab and then fixed in place.

The original SPEX SamplePrep swing mill was developed
for cement plants and steel mills with open, noisy lab
conditions, and is still used in many locations where the
working environment requires a rugged, simple mill. The motor
is protected by a perforated shield to allow ample air-cooling for
continuous running and a rubber “skirt” shields the drive mechanism
but is easy to move aside when the drive belts need replacement. The
8500 Shatterbox can be plugged into
a standard lab timer. It is shipped
with a rubber-matted plywood
base to prevent it from
“walking” during operation.

Grinding Containers and Accessories
The SPEX SamplePrep Shatterbox® swings a dish-shaped grinding container in a
tight, high-speed horizontal circle. Inside the container are the sample, a puck, and
(in larger containers) a ring. As these grinding elements swing free inside the container, the sample is rapidly crushed between the walls of the container, puck, and
rings, and further reduced by the millstone-like action of the puck and ring against
the container floor. Grinding times are usually between two and five minutes, with
resultant particle size well below 200 mesh. With grinding aids, smaller samples can
be reduced below 10 microns.

The standard SPEX Sample Prep
Grinding Container, is available
in a variety of materials. Maximum
grinding loads for cement, rock,
slag, etc. are 60 mL for the
tungsten carbide container, 50 mL
for the steel, and 40 mL for the
ceramic containers.
There are also small grinding
containers available in hardened
steel or tungsten carbide which
can be run three at a time in
the 8507R Rack. These have a
maximum sample size of 20 mL.
For especially large samples with
a maximum size of 100 mL, the
oversize steel grinding container
can be used.

Accessories
Grind up to three samples at a time with
the 8507R Rack. It holds one or three
8507 or 8508 grinding containers and
lifts easily in and out of the Shatterbox.
Other available Accessories include the
31688 Friction Disc, a durable rubber
pad which reduces operating noise and
wear, and the 8525 Transporter, specifically designed to lift and hold all large
Shatterbox dishes while transporting
them between the sample preparation
and Shatterbox areas.
