Gypsum is frequently pelletized to
improve handling and product
characteristics, particularly for use as a
soil amendment.
Gypsum is frequently pelletized to
improve handling and product
characteristics, particularly for use as a
soil amendment.
Pin mixers are used in the pelletizing
process as a precursor to the disc
pelletizer.
This provides a conditioning stage that sets a
precedent for the rest of the process, and
the end product quality.

In addition to improving end product
quality, the use of a pin mixer also improves
subsequent processing steps.
A pin mixer consists of a central rotor shaft,
housed in a stationary casing. The shaft is
fitted with several rods, or “pins.”
A pin mixer consists of a central rotor shaft,
housed in a stationary casing. The shaft is
fitted with several rods, or “pins.”
The rotational movement of the shaft and
pins at a constant speed of several
hundred rpms creates a high-velocity
spinning action.
This spinning action reduces water volume
between particles and results in material
densification much greater than what can
be achieved with other agglomeration
equipment.
Increased ProductionDensification is carried out in the pin
mixer instead of on the pelletizer, which
would otherwise be a lengthy process.
Reduced Binder CostsBecause material is densified through
motion and not through the use of
additional binder, less binder is required.
De-DustingRaw powdered gypsum is very dusty.
Conditioning it in a pin mixer with a
binder creates a mixture that is nearly
dust-free, and much easier to handle.
Pre-ConditioningConditioning gypsum in a pin mixer
prepares it for optimal agglomeration
on the disc pelletizer, improving
processing, and helping to create a
premium end product.
ConclusionPin mixers are a valuable part of the
gypsum pelletizing process, helping to
create the best end product possible,
streamlining production, and de-dusting
gypsum so it is easier to work with.

development, and manufacturing of gypsum
processing equipment, including custom,
high-quality pin mixers.
