Different tungsten carbide qualities with a hardness above those of the standard and PM special qualities. Through clean grinding materials, we achieve a long working life through high resistance to wear.

Clothing instead of landfill PET must beone of the most interesting recycling materials of recent years as, during this time, not only new bottles, but also clothing and much more have been produced from recycled bottles. In Germany alone, each year the volume of PET bottles discarded when empty has exceeded 400,000 [tonnes], 96% of which is taken to professional recycling. An additional 60,000 tonnes arises annually as packaging material. However, PET is an extremely abrasive material, which exacts enormous demands on the tools used in recycling. Our knives have been proven by their high resistance to wear, and we also supply, in addition to our proven quality standards, extremely hardwearing special qualities.

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.

The high-shear mixer is a system for mixing, granulation of pharmaceutical powders and granulated products. Moreover, it is suitable for a wide range of cosmetics and food products. A three-bladed mixing tool rotates in a vertical, cylindrical mixing vessel close to the wall and to the bottom of the vessel. The shape and peripheral speed of the mixing tool create a vortex-like circulation of the mix. A separately driven chopper is used for breaking up agglomerated products as well as for moistening and granulation. Liquid addition is either gravimetric or uses a pump to add liquid directly to the effective range of the chopper, so that the best possible distribution is ensured. The optional wet sieve on the discharge ensures a completely homogeneous distribution of the granulate size. The PC/PLC-based control system to be compliant with CFR-21 Part 11. The updated user interface permits intuitive machine operation in service and automatic mode for production and cleaning operation.

The CoriMix® is a high-speed, continuous mixer for high throughputs, especially developed for homogeneous mixing of liquid and pasty components into dry substances. The system is based on the high peripheral speed of the mixing shaft tools of up to 50 m/s. The product is moved through the mixing chamber in a plug-flow manner. The retention time 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. Liquid components are introduced directly into the product ring layer – either via tangentially placed liquid pipes through the drum wall or via a hollow mixing shaft with specially perforated tools. However, moistening of the mixer wall and shaft is largely prevented. The liquid distribution is similar to a nozzle but avoiding any risk of clogging or disturbance of the spray.

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.

Recycling made easy Our machine knives, of uncompromising quality, have been used for decades in recycling for tyre crushing. Even when separating rubber and spring steel, they have been proven in practice day by day. Whether shredder knives, spacers, scrapers or sealing gaskets, shredder teeth for multipleshaft shredders, rotary and stator knives for granulators or machine knives for guillotines Our complete range of products also covers the most demanding challenges in recycling.

Optimum crushing instead of cable salad The very best method for crushing of cables or electrical scrap has brought many a tool to its limits and yet this is a frequently underestimated source of money. In addition to expensive copper, the recycling process also recovers aluminium and noble metals. In order to reach these valuable raw materials, robust preliminary crushing units are used, followed by a second crushing cycle. The demands on the crushing knives cannot be ignored and they must therefore be very tough. We are at the side of our partners to give advice on the selection of ideal materials and the best heat treatment.

We also supply an antistatic agent for subsequent or sustained application in liquid form.

The granulation dryer is designed for continuous operation. A unique property of this dryer is its combination of convection and contact drying. Adaptation of the retention time to the specific process ensures that products are dried at low temperatures. At the same time, excellent granulation of the final product can be achieved. This intense mixing effect separates the particles in the fluid bed, thereby creating a large product surface and preventing the generation of temperature and moisture gradients in the product bed. This leads to a significant increase in the heat exchange via the heated drum walls. The product behaviour during drying is affected by the mixing tool geometry and choppers can be activated as an option; these can be used to control the average product retention time and the retention time distribution. It is therefore possible to achieve a defined grain size distribution during granulation processes

The sliding surfaces used in the past had a number of weak points, which can be attributed to the granules used: Quartz sand is too hard and destroys the base coverings very quickly, while the various rubber granules are too soft and too uneven in shape, so that they in turn are ground up relatively quickly. Both sliding media are controversial due to the dust they generate and bring with them unpleasant side effects such as breathing difficulties, discolouration of clothing and a great deal of cleaning work in the tennis hall and social areas. A new manufacturing process has made significant progress possible: Perfect-Glide tennis granules are not ground from a block of rubber like conventional granules, but are spun into threads using an extruder and then cut to a defined length in a cooling bath. This process enables the production of fine, dust-free extruder micro-granules in a new, optimised lens shape.

Extremely durable materials place extreme demands on the knives with which they are processed. Our knives are customized for a wide variety of material mixtures and therefore perform excellently in cold and hot cutting processes.
