Contract Pelleting
<<Back to Toll Processing
Decades of granulation
and pelleting experience is used to solve a wide range of
client pelleting problems first in our laboratory and then
scaling up these pelleting process solutions in our vertically
integrated granulation and pelleting facility. We
efficiently develop and manufacture our clients'
products employing a variety of these process
pelleting technologies.
Development and/or production
pelleting applications from our past experience include:
| Plastic Additives |
Water Dispersible Granules |
| Insecticides |
Fungicides |
| Organic Fertilizers |
Sweeteners |
| Candy |
Gelatins |
| Colors |
Antioxidants |
| Stearates |
Flame Retardants |
| Animal Feed Supplements |
Nutraceuticals |
| Cosmetics |
Polymers |
| Controlled Release Products |
Food Additives |
| Inorganics |
Pigments |
| Catalysts |
Detergent Additives |
We utilize the following key
equipment:
Powder Mixing with Optional Liquid Addition:
Our plow mixer with optional use of high intensity
choppers is used to obtain a uniform blend. For
products that require a wetting agent, liquid is
added to form a mass suitable for extrusion.
Low Pressure Basket Extrusion / Medium to High
Pressure Pelleting:
Our high pressure Pellet Press is used to compress
material into pellets. Various die plates are
available to match the application. Our low pressure basket extruder can be
utilized as needed for lower pressure and wet
granulation applications where quick dispersion is
required.
Spheronization as needed:
Our spheronizers can be utilized when our client
products need to be made into spheres for either
functional or aesthetic reasons. We can
operate either on a batch spheronization basis for perfect sphere
forming for this process step or continuously
spheronize when
only slightly rounded pellets are necessary.
Pellet Cooling and Drying as needed:
Our vibrating fluid bed processor is used to cool
the pellets so that they can be packaged safely. For
pelleted products that require drying, up to 300° F air can
be used to remove moisture. Drying / Cooling air is
filtered before exhausting. The pellets are
screened to remove any fines.
Sample Analysis:
Standard product analysis of the pellets such as bulk density,
moisture content, and particle size analysis is
available. Other analytical techniques can be offered through
special arrangements.
Plant Design and Material Limitations:
The pelleting facility has appropriate electrical design,
explosion relief and safety considerations to handle
Class 1 powders (KST less than 199)
Pelleting Formulation Development and Testing
is Available:
We carry out development projects for product
optimization based on the client goals for active
loading level, pellet size, crush strength, dmin/max, release profile,
flow characteristics required. These studies can be either simple
refinements or complete development efforts. The final goal is
to create a client required pelleted product. Typical studies can range from
several days to 6 to 8 weeks.
