Metal Seperation at a Sugar Cane Refinery

Application Notes & Case Studies /

Due to high humidity and the adhesive nature of sugar, the customer’s existing magnets were
incapable of providing ferrous metal capture or processing equipment protection. Magnetic tubes, which were supposed to capture contaminants, were instead coated in sugar and, as a result, when cleaning occurred by actuating tubes through stripper seals, the seals were cracking and falling into the “pure” product stream. Additional contaminants were simply “washed off” the tubes because of the weakness created by the sugarcoating and air gap.
IMI demonstrated the mechanical advantages of IMI’s unit side-by-side versus their current housing;
the IMI unit pull-tested stronger- with nearly 40% more holding power.

Custom Drag Conveyor for Hot Pellets in Cargill Animal Feed Plant

Application Notes & Case Studies /

Cargill is one of the largest producers of animal feed products in the world, generating over 20 million tons of feed per year. Cargill feed products support livestock production that ultimately touches the plates of more than one billion people every day. Cargill Animal Nutrition in Ogden, Utah required a custom replacement drag conveyor to handle hot pellets fed directly from their pellet mill. The existing equipment was located within a highly confined area, making the outer dimensions of the replacement drag conveyor critical. The pellets also needed to be conveyed downstream while maintaining their shape and avoiding damage. KWS designed and engineered a long-lasting custom conveying solution for Cargill.

Powderization of Dried Chili Peppers

Application Notes & Case Studies /

Chili pepper is a “hot” spice used in the majority of Mexican-style dishes. The size reduction of chili pepper is limited by the hard chili pepper seeds. These hard seeds are very difficult to mill. Therefore, it is important to select a screen with holes that are slightly larger than the chili pepper seeds. Also, chili peppers are heat sensitive. Therefore heat rise may be a concern at a finer particle size.

Screening Lumps and Foreign Particles from Sugar

Application Notes & Case Studies /

Each of the high-capacity VIBROSCREEN units can screen up to 36 tons/hr. The rate at which material passes through the screeners depends in part on the last time they were cleaned. In conformance with GMP requirements, SBS cleans the screeners with steam and hot water either once a week or after a load. Personnel inspect the screeners after every loading operation to see if immediate cleaning is required. All material contact surfaces are of 304 stainless steel.

Heavy-Duty Tubular Incline Screw Conveyor to Convey Extremely Abrasive Alumina for Major Recycler

Application Notes & Case Studies /

This project offered a unique bulk material handling challenge due to the extremely abrasive characteristics of crushed alumina. KWS offered years of experience and expertise in conveying alumina and other extremely abrasive products. Because of the existing plant layout, Aleris required a 54-foot long screw conveyor to transfer crushed alumina from a screener to another conveyor. Aleris had used screw conveyors in the past with very disappointing results. Their previous solutions were poorly designed and a maintenance nightmare. Internal screw conveyor components such as screws, coupling shafts, hanger bearings and trough liners were only lasting a few weeks and adding tremendous amounts of downtime and additional labor costs.

Easy Clean-Out Screw Conveyor for Milled Grain Industry

Application Notes & Case Studies /

One of North America’s largest food and ingredient companies operates a plant in Indiana and mills a wide variety of premium corn masa flours used in the production of tortillas and corn chips. The plant can produce nearly 32,000 tons of corn masa flour annually. KWS engineered and manufactured a screw conveyor to transfer corn flour from a cyclone with a rotary airlock and then to a rotary distributor that divides the material into four ports for the sifting process.

Screw Conveyors for Corn in Masa Making Process

Application Notes & Case Studies /

A large North American food and ingredient company was expanding operations at their plant in Texas. Corn is processed and milled to make corn masa, the primary ingredient in tortillas, tortilla chips, and masa for tamales. KWS designed and manufactured several screw conveyors to be fed by weigh belt feeders and loss in weight feeders on the raw grain side of the process.
