ROLLEX /FD SERIES DRYING PLANTS

The operating principle of the direct flame version (FD) is based on direct exposure of the product to the flame of the support burner associated to the rotation of the drying chamber where the material for treatment is constantly inserted. The material is mixed and fed into the cylinder with an exclusive patented rotating cage system.

The partially dried and crushed product then enters the secondary drying chamber where it changes direction and is sent with a second cage system towards the discharge hatch placed near the burner thus reaching the desired dry level.

The flow of fumes and granular substances leaving the dryer is extracted with a forced suction system and sent into a stainless steel cyclone dust separator.

After leaving the cyclone the fumes are sent into a thermo purification chamber where it is heated to 500-600° C by the secondary burner and thus completely purified.

The Rollex FD direct flame plants, made in three different models, stand out for:

• Thermo purification of exhaust fumes, for more ecological emissions;
• High level of reliability for the system controlling process parameters.
