Heating element for dry material preheating
Fives Solios
Principle
Indirect heating by HTM (Heat Transfer Medium)
Two (DUO) or four (QUATRO) shafts fitted with holo-flights for HTM circulation
High heat exchange efficiency
Control of outlet material temperature
Slow rotating speed to avoid degradation of product grain size and reduce wear
Mechanical design
Spiral system designed by flight welded on wrapping tube to allow steel thermal expansion
Rotary joints with graphite seal
Supporting bearing with spherical roller bearing and carbon bearing.
Robust drive ensured by bevel gearboxes and planetary joints.
