Manufacturer Information

FEECO International

FEECO manufactures industrial process equipment and systems for thermal processing, agglomeration, material handling, and bulk solids applications. Rotary calciners are used for controlled high-temperature processing where material requires a specific thermal treatment profile.

This FEECO 3-zone indirect rotary calciner system was designed for calcium carbonate processing and features an approximately 2.36 ton-per-hour stated throughput, 304L stainless steel construction, natural gas combustion, and Allen-Bradley controls.

Description

Available for sale is a used FEECO 3-Zone Indirect Rotary Calciner System, Serial Number D20215011, built in 2021.

The calciner measures approximately 66" diameter x 50' long and is constructed of 304L stainless steel, with a stated shell thickness ranging from approximately 3/8" to 3/4". The system has a stated design throughput of approximately 2.36 TPH and was designed around calcium carbonate as the process material.

Thermal protection includes 2,300°F firebrick refractory and 2,600°F ceramic fiber refractory. Natural gas combustion is provided by 11 burners, supporting the unit's three-zone thermal processing configuration.

Automation includes an Allen-Bradley PLC, PanelView HMI, and Fireye burner management system (BMS) controls for process and combustion control.

This heavy-duty calciner may be considered for mineral, chemical, and specialty-material thermal processing applications where controlled heating, calcination, thermal treatment, or material transformation is required.
