BEST PRACTICES FOR SPEC MIX
4. Using the bulk bag hook, pull the dust containment
chute down and hook the b-lock on the outer chute
at the bottom of the bulk bag. Pull the b-lock to
open the outer chute
5. Using the bulk bag hook, pull the dust containment
chute down and hook the b-lock on the inner chute
at the bottom of the bulk bag. Pull the b-lock on the
inner chute to begin dispensing material into the
silo.
6. Immediately remove the bulk bag hook to allow the
dust containment chute to compress up into the
bottom of the bulk bag, contianing any dust as the
material dispenses into the silo.
7. Climb down the ladder as the material dispenses
into the silo to minimize exposure to dust while
filling the silo.

BEST PRACTICES FOR SPEC MIX
®
Silo Mixing Procedures:
1. Position silo in an area of open wind, avoiding
enclosed or confined areas.
2. Position the silo so the mason tender can be
positioned with a crosswind over the mixer or
downwind to keep dust from blowing into the face
of the worker while mixing. Many SPEC MIX silos
are equipped with rotating gate that allow for the
handle to be moved without moving the silo itself.
To keep rotating gates working properly, keep
grease in zerts and make sure to open the gate
before attempting to rotate it to remove downward
force from the weight of the material on the gate
when rotating.
3. Fill the mixer with sufficient water to receive
the material. It is beneficial to keep the initial
batch wetter than required for final use to ensure
complete hydration of the aggregate, reducing dust
when charging the mixer and increasing board life
of the final product.
4. When opening the gate, take a stance that is away
from the discharge of material to limit exposure to
nuisance dust.
5. Open the gate with even force and only as wide as
needed to allow for a good steady flow of material
into the silo. Opening at too great of a distance can
cause product surges that have the potential to
increase nuisance dust on site.
6. When the desired amount of material has been
dispensed into the mixer, shut the gate with even
force, maintaining distance from the mixer.
7. As the wind shifts, make sure to position with
a cross wind or downwind to continue to avoid
nuisance dust
