Introduction to Loedige Process Technology

With the invention of the Ploughshare® Mixer and introduction of the hurling and whirling principle, Loedige has set a high standard for mixing and processing technology. Patented innovations have ultimately had an enduring influence in this field. Technologies for mechanical processing, developed over decades of close cooperation with our customers, now make it possible for Loedige to provide optimal, customized solutions for every kind of application in the fields of mixing, granulating, coating, drying and reacting.

Loedige's range of products also includes the following divisions:

A range of polymer mixers, which is a house hold name in all sectors of the polymer industry.
 

In May 2003 Loedige took over the DRAIS Mixing and Reacting division.

Loedige combines the complex correlations between product properties and specific industrial and production requirements in a user-friendly system design. Experience gained in the realization of more than 20000 machines and systems give a sound basis for providing the right solution for each new application.

Loedige provides process solutions for mixing, drying, reacting and granulating application in the following industries:

• Plastics • Animal Feeds
• Food • Minerals and Basic Materials
• Pharmaceuticals • Chemicals
• Environmental Technology • Fibre Reinforced Composites
• Building Materials • Paints and Pigments
• Wood and Ligno Products • Cosmetics

Here are some examples of tailormade system solutions in a variety of areas of application

Pharmaceuticals - Granulating
System solution for mixing and moist granulation of tablet materials. The Mixing Granulator is fed dust-free from drums using a lifting column. A rasp can be connected downstream if this is required by the recipe. PLC and PC supported unit controls are provided for semi-automatic processing, recipe administration and documentation. In addition to installation and commissioning, qualification and validation are also included in the scope of supply.
 

Chemical Products - Reacting
Druvatherm® Chemical Reactor DVT 30000 installed in a unit for the production of methylcellulose (MC) with a production capacity of 5000 MT per annum. Similar reactors have been supplied for the production of a wide range of cellulose ethers, e.g. HEMC / HPMC / HEC / EHEC and CMC. Starting with wood pulp or linters, cellulose is converted to cellulose ether in the following process sequences: alkalization, etherification, viscosity adjustment and solvent recuperation, all in a single batch. The cellulose derivatives are used in the following industries: foodstuffs, pharmaceuticals, chemicals, building materials, detergents, crude oil drilling, textile and paper.
 

Moulding Compounds and Fibre Materials - Mixing and Drying
Batch Ploughshare® Mixer for mixing and aeration drying of friction lining materials. Due to their poor flow properties, fibres are added by a manually filled, container tilting system. The mixer is equipped with a heating/cooling jacket, appropriately designed filter unit directly installed on the mixing drum and choppers to disperse the fibres. The treated product is then emptied into mobile containers for transport to downstream processing machinery.
 

Environment - Mixing and Granulating
Mobile, universal unit for the production of a reliably briquettable mix from different kinds of dusts. The product of continuous Ploughshare® Mixers has the homogeneous moisture essential for the strength and stability of briquettes. The mixers are fed, dust-free, from big-bags or silos. Controlled dosing of appropriate quantities of binding agents can be programmed as required. The semi-automatic operation of the unit also involves self regulation of the integrated product storage container.
