CONSTRUCTION

Our experienced designers use CAD workstations and modern software to work on a broad range of problems like designing machines or different components, optimizing spare parts or different fields of research and development.

PROCEDURAL DESIGN

At ZADCON, our own experts work at procedural dimensioning of rotary machines and their accessories. Furthermore we work closely with the Institute of Fluid Mechanics and Thermodynamics of the Otto von Guericke Universit├Ąt in Magdeburg, and with Prof.Dr.-Ing. Specht and Jprof.Dr.-Ing. Herz in particular, and a number of other universities, colleges, research facilities and specialized companies.

CONTRACT MANUFACTURE

ZADCON is not bound to any particular manufacturers, even though we work closely with several excellent partners, some of them near our headquarters. Because of our way of working, we have both: quality and short distances. Production control and inspection is being handled by our specialist engineers.



ASSEMBLY

Our products are shipped worldwide and assembled locally by specialist installation companies.

SUPPORT

Our support writes expertises for existing plants, replaces broken or wear parts and optimizes facilities. They also work at assembling our machines, and offer advice on questions concerning process engineering. Furthermore they are active around the world to support operators of plants, that have been built by ZAB Dessau.

SHIPMENT OF SPARE PARTS

We ship spare parts and constructional components for mechanical and systems engineering around the world. Spare parts include pinions, bearings, shafts, tyres, carrying rollers, girth gears and many more.

Components

We design, manufacture, and ship:


Rotary Kilns

Rotary kilns designed and manufactured by us are used for the thermal treatment of various bulk solids.

Multitube Coolers

Tube coolers are mainly used to cool free flowing and fine-grained bulk solids. Tube coolers* can be considered a kind of indirect flash cooler, for the coolant does not come into contact with the bulk material.

Cooling Drums

Flash coolers are a kind of direct rotary cooler, and are mainly used to cool free flowing and fine-grained bulk solids, but also to cool agricultural products like beet or sugar beet cuttings, dry leaves, soilage, pressed pulps and grain.

Sectional Coolers

Sectional coolers are used to cool fine-grained or coarse-grained bulk solids. The heat is extracted when the bulk solids come into contact with cool sectional surfaces*. Sectional coolers can be considered a kind of indirect drum cooler.

Pyrolysis Kilns

Pyrolysis takes places in an evacuated environment. Pyrolysis kilns are often used for waste pyrolysis, and other processes involving pyrolysis.

Rotary Dryers

Dryers made by ZADCON GmbH are both used to dry easy-to-dry materials (sand, gravel, waste glass) and hard-to-dry materials (e.g. clay).

Tube Mills

Tube mills are mainly installed in the form of ball tube mills, meaning they utilize ball charges. In some cases rods may be used for milling.

Longitudinal Kiln Adjustments

Longitudinal kiln displacements are used for the axial displacement of rotary kilns, dryers and drums for a uniform load and wear of the surfaces of the girth gear/pinion or of the tyres and carrying rollers.

Separators

Separators are used for sizing i.e. separating fine-grained builk solids into grain-size categories. This is often needed in connection with crushing units, or with special tasks like producing bulk solids for distributing dust.

Seals

In this context, it means sealing a rotating tube towards a fixed inlet or outlet. ZADCON offers different kinds of sealing, each optimized for the conditions it will be used under.

Further components

Parts for machines and plants related to the above mentioned main units.

Spare Parts

We ship spare parts for plants produced by ZAB Dessau.
