Process Equipment

Food, pharma, or industrial, there is a best method for feeding, grinding, blending, and sorting everything. We provide custom designed, fabricated, and integrated processing systems for all types of bulk dry solids, powders, and some slurries. 

SCREW & VIBRATORY FEEDERS

VOLUMETRIC FEEDERS

Volumetric feeders estimate the amount of product being fed based on the feeding mechanism’s speed (vibration intensity/screw speed) and known average product consistency.

GRAVIMETRIC FEEDERS

Gravimetric feeders measure the actual amount of product being fed by placing the bin, feeder, etc. on load cells and stopping the feed when the target weight is reached.

LOSS-IN-WEIGHT FEEDERS

Loss-in-weight feeders operate similarly to gravimetric feeders and allow continuous feeding of product. They dynamically compare the weight of the feeder’s tank to the weight of the product being fed into it.

PARTICLE SIZE REDUCTION

JAW CRUSHERS

Jaw Crushers use jaw plates to compress and shear product into coarse & intermediate particles. Sturtevant’s models offer material reduction up to an 8:1 ratio and from ½ – 10 tons/hr.

ROLLER MILLS

Roller mills employ roller-to-roller or roller-to-plate methods to crush product into granules while minimizing powder. The Roll Crusher® offers material reduction up to a 4:1 ratio and from ¼ – 44 tons/hr.

ROTARY CRUSHERS

Rotary crushers shear product between grinding nuts and the case’s wall liner. They produce granules and are commonly used for coal, limestone, and salt. Sturtevant’s Rotary Crusher is available in 1-10 ton/hr capacities.

DISC MILLS

Disc Mills create uniform product for materials like chemicals, ceramics, minerals, and glass. Sturtevant’s Sample Grinders can produce particulate as fine as 100 mesh and come in capacities from 50-800 lbs./hr.

JET MILLS

Jet mills utilize particle-on-particle attrition to grind product. The Micronizer® is the most popular jet mill in the world, employs a unique fluid energy grinding system to produce sub-micron sized particles, and avoids the generation of heat during the milling process.

HAMMER MILLS

Hammer mills crush product with swinging bar hammers and screen particles with grates and screens. They are a general solution for milling most friable materials from pharma and food to chemicals and limestone. HAMMERMILL® capacities range from ½ – 6 tons/hr.

PIN MILLS

Pin mills use shafts to break up either solids or fluid suspensions with repeated impact.  They’re ideal for milling particles down to a few micrometers when heat will not degrade the product. The Simpactor® is a centrifugal, high-speed, screenless pin-type impact mill that reduces low to medium-density materials to uniform sizes of 50-200 mesh.

INFESTATION CONTROL MILLS

Infestation control mills kill insects without the use of chemicals. The Infestroyer® accelerates product by centrifugal force through a single set of whirling rotor pins. Impact with the pins and corrugated wall destroys larvae, eggs and insects ensuring 100% kill without over-grinding the product.

SCREENERS & SIFTERS

STATIC SIEVES

Cross-flo static sieve screeners & separators are for solid/solid or liquid/solid separation. They are electricity-free and remove oversized particles from free-flowing bulk dry solids or solid materials from wastewater at ultra-high rates.

VIBRATORY SCREENERS

Vibroscreen sieve screeners & separators classify, de-dust, sift, or de-lump bulk dry solids or solid-laden slurries. These vibratory screeners separate product into up to 5 sizes using different sized screens which can be changed based on the application. FLO-THRU models are also available for applications with particularly stringent height parameters or high temperatures.

CENTRIFUGAL SIFTERS

The Centri-Sifter uses centrifugal force to propel materials against the screen of the cylindrical sifting chamber. The helical paddles used to perform this action avoid contact with the screens while breaking up soft agglomerates and ejecting over-sized and unusable particles. This solution by Kason is the ideal choice for continuous scalping of dry or moist materials, even those that tend to clump. It is also particularly effective at separating liquids from solids.

AIR CLASSIFIERS

Air classifiers sort dry product by particle size for product de-dusting and improved grinder performance. Available in both stationary and mobile units, the largest option is the Whirlwind®, which is self-contained and does not require process dust collection equipment. It can separate powders in the range of 100 to 400 mesh (150-38 microns). The Side Draft also operates in the 100 to 400 mesh range, but additionally features variable speed controls. The SuperFine Air Classifier is used to separate powders in the range of 5 to 44 microns.

MIXERS & BLENDERS

PADDLE BLENDERS

Paddle Blenders have U-shaped horizontal troughs and paddles moving product in opposing horizontal and vertical directions. Paddle blenders are typically used for feed and grain, non-directional slurry mixes, particulates, abrasive products, pastes, filter cakes, and fragile/friable products. They’re also used for effective mixing of significantly under-capacity batches.

RIBBON BLENDERS

Ribbon blenders are one of the oldest automated mixing methodologies use u-shaped troughs with opposing sets of helical agitators, one inner, and one outer. By forming 2 opposing cyclones within the product, they create homogeneous mixes quickly but create some heat and can degrade some products.

PLOW BLENDERS

Plow blenders are well-suited for applications requiring vacuums or high pressure. They use wedge-like plows attached to a high-speed rotor to lift the product and create a weightless effect, helping negate problems caused by differences in particle size or density. They’re adept at mixing solids to solids, liquids to solids, and solids to liquids for a wide range of applications.

FLUIDIZERS

Fluidizers are a class of paddle blender meant for mixing finely divided solids with varying densities. The paddles are smaller, differently shaped, set at decreasing distances along the shaft, and spun more quickly than what is typically referred to as “paddle” blenders.

HYBRID MIXERS

Hybrid mixers combine the opposing-stream concept of the of the ribbon blender and some of the gentleness of the paddle blenders. This creates a more turbulent environment throughout the whole mix as opposed to more locally around the mixing components.

BOLTED PADDLE

When mixing abraisive materials, paddles can experience abnormal wear. By using removable paddles you can maintain effectiveness of the mixer while managing costs. The trade-off is cleanability. 

BOLTED ARM

When mixing materials so abrasive they wear down even the arms, those can be made bolt-on as well. Further cleanability is exchanged but in such cases sanitization is rarely a concern.

ANCILLARY EQUIPMENT

LEVEL INDICATORS

Level indicators (also known as level sensors or capacitance probes) come in many styles: vibratory, sonic, optical, radio frequency, and others. We carry numerous brands along with other custom solutions to help settle caking and bridging products so the indicators can get accurate readings.

PROCESS CONTROLS

Processes can be as sophisticated or as simple as needed for any application. Whether you’d like to manually portion ingredients for a single step or push a button on a tablet to take a batch all the way to completion, we deliver custom solutions with programming and operation support.

DRYERS/COOLERS/
MOISTURIZERS

The Vibro-Bed uses air & vibration to maximize material’s surface area and therefore the rate at which it can be dried, cooled, or moisturized. Kason’s solution comes in sizes from 18 to 84 inches diameter for laboratory and pilot testing to high-volume processing.
