Extrud-O-Mix®
The Extrud-O-Mix® is a unique product line that eliminates
typical boundaries between mixing / blending and agglomeration equipment.
This efficient low pressure mixing and forming extruder can generate
uniform, free flowing, dust free pellets or particles. The Extrud-O-Mix®
is primarily designed for combining dry powders with liquid streams
to produce a paste or dough suitable for extrusion. However, with
efficient continuous mixing, adjustable shear input, and heat transfer
available in the housing and the rotor the application list becomes
very diverse.
Compacted products, including those extruded in high-pressure systems,
generally have poor mechanical dispersion and/or dissolving rates.
The Bepex International Extrud-O-Mix® uses the minimum force
necessary to obtain a dust free particle with good particle integrity
while maintaining excellent dispersibility.
One common application for the Extrud-O-Mix® is back mixing
or simply forming wet cake products to improve drying efficiency.
A more specialized approach is using the Extrud-O-Mix® as
a product conditioner before spheronization and drying. The Extrud-O-Mix®
is available in several arrangements and sizes from the lab scale
Model EM-2 to high production units with 200 hp drives.

System 1
In the extrusion system pictured above a slurry feed is metered to the Extrud-O-Mix®, along with the necessary amount of recycled dry product. The Extrud-O-Mix® acts as a backmixer to mix the slurry with the dry recycle material to form a product that is able to be dried in the Fluid Bed. The fines from the Fluid Bed exhaust, as well as fines from the post screening are recycled to the Extrud-O-Mix® feed.

System 2
In the extrusion system pictured above a powder and a liquid are fed into the Extrud-O-Mix® for mixing and conditioning. The Extrud-O-Mix® product is then dropped into a Bexroller in semi-batch mode. The Bexroller rolls the pellets to form a spherical product. The spherical product is then discharged into a Fluid Bed dryer for drying and conditioning. Fines from the process are recycled back to the Extrud-O-Mix® feed.
