Ringlayer mixer for continuous operation

Lödige has years of expertise in continuous granulation. Nowadays, continuous ringlayer mixers are established systems for continuous granulation in many industries. However, until now the Lödige product range was missing a suitable dryer. The continuous fluid bed dryer closes this gap. Together with the ringlayer mixer CoriMix® and the customer-specific dosing system, this dryer provides a complete continuous granulation line: GRANUCON®. Dryer operation is based on the fluid bed process. A general disadvantage of continuous fluid beds is the wide retention time distribution within the machine. Lödige’s developers have looked into this problem and have found a solution: integrating a screw in the fluid bed dryer. This has a limiting effect on the retention time distribution. — Exchangeable floor — Quick screw removal — Integrated WIP cleaning — Individual purging of filter elements

The continuous ploughshare mixer uses the mixing and fluid process introduced to mixing technology by Lödige. The ploughshare shovels in special arrangement on a mixing shaft in a horizontal, cylindrical drum rotate. Their peripheral speed and geometric form are coordinated in such a way that the mix is moved out of the product bed against the centrifugal force and in axial direction at the same time. The mixing elements having a defined shape and a special arrangement on the shaft, they ensure not only a reliable product conveyance but also a sufficient back-mixing of the product. All the product is constantly involved in the process, ensures a maximum mixing intensity at highest throughputs and shortest residence times until the product is discharged out of the mixer via an outlet. The continuous process can be run at filling levels between 20 % and 50 % without influencing the mixing quality. Choppers can be additionally installed in the mixing drum.

The laboratory model supplements the well-established Lödige mixing granulator range. The laboratory mixing granulator permits the same process steps as the production machines: — Mixing — Moistening — Granulation — Temperature control (using double jacket) The laboratory mixing granulator is delivered operation-ready with a CE conformity declaration. For the sizes, please refer to the machine flyer. A three-bladed impeller rotates at the bottom of the vertical, cylindrical mixing vessel, to create a vortex type of circulation for the material to be mixed. Very short mixing times and excellent mixing quality are achieved, even if the product components are extremely different. The separately driven chopper (only for the 5, 10 and 15 l vessel) is designed for breaking up of agglomerated material, for uniform moistening, wet granulation and streak-free mixing of dyes, as required.
