Products
Lödige Ploughshare® Mixer for batch operation type FKM
The ploughshare mixers for batch operation use the mixing and fluid process introduced to mixing technology by Lödige. High-quality mixes are achieved through equipment with tools which are adapted perfectly to the respective task. Mode of operation: The fluidised bed generated mechanically achieves intensive separation of particles, especially in the upper area of the mixing drum. This optimizes the surface contact of the particles with liquids permitting lump-free mixing and homogeneous distribution. Lödige ploughshare mixers can be used for a wide range of applications – for processing bulk solids (powdery, grainy, fibrous) or pumpable products. Products of different bulk density and structure can be easily mixed. Choppers can be additionally installed in the mixing drum to increase the turbulence in the mixing process. This also ensures the mixing of fine particles in small quantity and enables the dispersion of product agglomerations and primary particles. We develop customised solutions, adapted perfectly to your application and product, for any of your tasks. • Extremely high mixing quality • Short mixing times • Reproducibility of batches • Gentle product treatment • High availability • Low-maintenance mixer concept • Easy accessibility of all internal mixer components • Multi-stage processes in one machine
Lödige Ringlayer Mixer CoriMix® for continuous operation type CM
The CoriMix® is ahigh-speed, continuous mixer for high throughputs, especially developed for homogeneous mixing of liquid and pasty components into dry substances. Mode of operation: The system is based on the high peripheral speed of the mixing shaft tools of up to 50 m/s. The resulting centrifugal force forms a concentric ringlayer of product along the drum wall. The product is moved through the mixing chamber in a plug-flow manner. The retention time depends on the filling level, speed, geometry and mixing tool adjustment as well as the throughputs but is extremely short compared with a continuous ploughshare mixer. The mixing chamber is divided into zones with different mixing tools enabling different shear intensity by selecting and adjusting the mixing tools according to each application. The friction of the product is increased through the high speed of the mixing tools but is still gentle enough due to the short residence time during the process. • Compact machine unit with high throughput • Extremely high mixing homogeneity • Versatile application options • Easy operation and cleaning • High operating reliability and service life
Lödige Ploughshare® Mixer for batch production type DBE for building materials
The ploughshare mixer for batch operation uses the mixing and fluid process introduced to mixing technology by Lödige. High-quality mixes are achieved through equipment with tools which are adapted perfectly to the respective task. The construction of this type of mixer with an outlet opening along the entire length of the drum ensures almost residue-free discharge of the product in the shortest possible time. • High quality products within minimum mixing times • Shorter discharge times due to one-door discharging system • Residual material < 0.1% due to 90° opening angle • Long service life span due to special mixing elements • Low maintenance seal system due to the single door Areas of application • Dry mortar • Cement • Tile adhesive • Filling agents • Refractory materials • Gypsum based products cement • Insulating materials • Indoor and outdoor rendering • Insulation plaster • Building chemicals • Lime hydrate • Fillers
Lödige Ploughshare®-Mixer (Lab machine) for development and small production
Lödige laboratory mixers have a drum volume of 5, 10, 20 or 50 l. They combine our usual mixing quality with an extensive range of accessories to comply with a large number of requirements. The laboratory ploughshare mixers operate on the principle of a mechanical generated fluid bed introduced by Lödige to industrial mixing technology. Equipped with mixing elements which can be adapted to individual requirement, the mixes produced in these machines are of the highest quality. Mode of operation: The ploughshare shovels in special arrangement on a mixing shaft in a horizontal, cylindrical drum rotate closely to the wall. 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. In addition, the shape of the shovels lifts the product particles from the drum wall. 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. The so-called “mechanical” fluid bed generated in this way, whereby all the product is constantly involved in the process, ensures a maximum mixing intensity at even the highest throughputs and shortest residence times until the product is discharged out of the mixer via an outlet. Thanks to their form adapted to individual application and the speed adjustment, Lödige ploughshare mixers can be used for a wide range of applications – for processing bulk solids (powdery, grainy, fibrous) or pumpable products. For laboratory mixers with a volume of 50 l, the housing can be easily moved to the side permitting free access to the technical systems area. • Guaranteed Lödige quality • Attractive value for money • Functional design • Ideal for your product and process development • Table model or free-standing machine • Extensive range of accessories
Lödige Vacuum Shovel Dryer Druvatherm® type DVT
Lödige shovel dryers are batch vacuum dryers. The mixing elements are frequency-controlled for ideal adaptation to the process. Special rotating mixing elements, installed in a cylindrical drum equipped with a temperature control jacket, create a three-dimensional product movement (mechanically generated fluid bed). The resulting contact frequency of the particles with the heat exchange surface leads to incredibly short drying times. Mode of operation: The intelligent product movement ensures intense contact of individual product particles with the heated container wall while also providing very gentle product treatment. Optionally available rotating choppers, which are installed in the sides of the drum, break down any agglomerated product if a product phase transition is required. Fine particles pulled along by solvent vapours are separated by an installed, pneumatically purged filter and are returned to the drying product bed by the cleaning system. • Intense mixing prevents temperature and moisture gradients within the product • Maximum heat transfer coefficients ensure excellent dryer performance • Gentle thermal product treatment in vacuum mode • Multi-phase process (mixing, granulation, drying, cooling) • Cost-efficient solvent recovery

The so-called “mechanical” fluid bed generated in this way, whereby all the product is constantly involved in the process, ensures a maximum mixing intensity at even the highest throughputs and shortest residence times until the product is discharged out of the mixer via an outlet. The product inside the machine is moved from the inlet to the outlet in a pilgrim step manner: two steps forward, one step back. 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 to increase the turbulence in the mixing process. We develop customised solutions, adapted perfectly to your application and product, for any of your tasks. • Excellent homogeneity of the final product • Retention/mixing times and granulation processes can be adapted to the specific product • Gentle product treatment • Consistent reproducibility • High availability • Easy accessibility of all internal mixer components • Low-maintenance mixer concept
