Manufacturing Capabilities


GRINDING: We have hammer mills from 5 hp to 300 hp. The bulk of our work is accomplished an the 5, 8 and 20 hp models. We also have ACM's (Air Classifying Mills) of varying hp. An ACM is useful when the customer wants to minimize oversized particles. We frequently use our ACM's to grind material to less than 325 mesh (15 to 46 micron). We also utilize granulators such as a Stokes Granulator to grind softer material and for delumping products.

MICRONIZING: We use air jet micronizers when a customer desires to have a particle size in the range of 1 to 20 microns. To jet micronize powders, the powder must be hard so that it fractures upon high speed impacts with other particles. Soft material like rubber can not be air jet micronized because the material absorbs the impact and does not fracture.

BLENDING: Along with grinding, blending is our most popular unit operation. We have all types and sizes of blenders from ribbon blenders to high shear plow-chopper blenders. We can blend as little as a few pounds all the way up to thousands of pounds. We specialize in blending very small amounts of material (less than 1%) into large amounts of material.

SCREENING: We utilize Sweeco style screeners some with high frequency vibration for materials that are difficult to screen. We also utilize Centisifter style screeners for continuous in-line screening. For screening very difficult materials at small particle sizes we utilize air sieves that fluidize the powder and continuously clean the screen with an air wand.

BAGGING: We can bag your bulk material into open top, sewn bags and into valve bags at any desired weight.

CLASSIFYING: We don't often use this unit operation because it is fairly inefficient but it can be used for separating fine material from over sized material when both are very fine, "sticky" powders and the separation needs to be reasonably accurate.

CRYOGENIC GRINDING: This is necessary when the material to be ground is very soft, waxy and low melting. We can grind at minus 100 degrees F. or at minus 300 degrees F. This is a very useful unit operation for nutraceutical and natural materials that contain a lot of oil e.g. many seeds.

SPRAY CHILLING: Many times referred to as prilling. It is used for producing an uniform powder from waxy, relatively low melting bulk prodcuts. For example sterols come out of the reactor as liquids that harden in the drum. These can be remelted and spay chilled in a spray dryer equipped with cool air. Since this is a fairly expensive unit operation for relatively small quantities (e.g. less than 20,000 pounds) we have also developed a process for shredding and cryo grinding full drums of liquid that have hardened in the drum e.g. certain surfactants.

DRYING: We can spray dry powders from solution or slurry. We can vacuum dry powders that are heat sensitive. We also have a process that will dry solutions or slurries at very low temperatures (around 100 degrees F.) This is very useful for natural products where the active ingredient is very heat sensitive. It compares to freeze drying but is cheaper to operate.
