When prospective customers engage us to provide them with a customized material processing solution, they inquire, “With what materials are your rotary dryer shells manufactured?”

Our Sr. Application Engineers indicate to them that we have built thousands of rotary dryer shells using select metals from the full spectrum of carbon steels, stainless steels and alloys. Yet our recommended dryer shell design for your specific application will be primarily informed by your material’s specifications, your processing criteria, and your production goals. Each Louisville Dryer is custom-engineered and fabricated for your specific purpose.

For industries that process materials with exacting requirements (including distilleries, corn wet milling, wood processing, activated carbon and petrochemical), many common elements of our dryer design recommendations relate to temperature tolerance, pressure resistance, oxidation and corrosion resistance. For these extreme environments of high pressures, temperature and/or corrosivity, rotary dryers fabricated using alloy materials are well-suited for such tough service.

Rotary dryers fabricated with the wrong materials for your specific application can result in excessive wear, damaging corrosion and premature failure – all resulting in very expensive operational downtime.

Watch the following three video segments to learn more from our Application Engineering Team about our alloy-based rotary dryers:

What are your rotary dryers made of?
Which industries need rotary dryers built with alloys?

Learn which alloys Louisville Dryer Co. uses in their custom-built dryers and components, and which industries use them– including distilleries, corn wet milling, wood processing, activated carbon, petrochemical, pharmaceutical, food and others. See some examples of steam tube dryers that we have fabricated using various alloys.

Why would a customer need an alloy-built rotary dryer?
Which materials and processes would benefit from them?

In this segment, Louisville Dryer Co. identifies various applications requiring alloy-based rotary dryers – including considerations of chemical reactiveness (corrosion and wear from acidic or basic environments), potential contamination of the processing material by the dryer, and high-temperature tolerance.

What are some of the challenges when manufacturing rotary dryers with alloys?
And what production protocols and quality control measures do you employ to ensure the integrity of these alloys?

Hear from Louisville Dryer Co. about some of the challenges and QC protocols implemented when building rotary dryers with alloy materials – including our positive material identification tests, specific welding procedures to maintain alloy integrity, and diligent segregation of the alloy from carbon steel.

As you can see, Louisville Dryer Co. application engineers and dryer craftsmen have the industry knowledge, technical expertise, and proven experience to fashion a custom solution with The Lowest Cost per Revolution for your team.
