Pure efficiency:
Sludge conveyance with the tube chain conveyer

Moving wet sludge or adhesive products from A to B constitutes a major challenge for mechanical conveyers and pump systems. We have taken on this challenge and have optimized our tube chain conveyers for the purpose of transporting such materials. Smooth surfaces achieved through high-quality manufacturing methods, material pairing using a variety of stainless steels, and special materials for the discs facilitate problem-free transportation.

Customized conveyer systems

Because sludge comes in many different ways! And, therefore, the Schrage conveyer system is technically customized to perfectly match the corresponding bulk material. There are lots of different types of sludge in the various industries: e.g. sewage sludge or shredded waste in waste management facilities, coffee grounds or meat pulp in the food industry, applesauce or pomace in the beverage industry, wet ash or biomass in power plants, and much more.

All of these products have different characteristics. That is why we analyze each product sample
in our in-house pilot plant prior to the placement of an order. Conveying tests show which design and material are most suitable for the corresponding application. Because many details need to be clarified prior to the beginning of a project: Which of the five sizes (115 to 270 mm) will we
use to achieve the desired conveying capacity? In general, outputs of up to 80 m³/h are possible. Which layout is ideal for an undisturbed product flow? And which design will allow for an energy-efficient and low-wear operation of the conveyer system in each individual case? All of these questions are thoroughly investigated by our engineers - nothing is left to chance.

The right accessories for
any kind of sludge

Depending on the adhesiveness of the
product, special accessories may be
indispensable. For example rotating
bridge breakers to support the infeed.

Alternatively, knocking units can also be used to support the infeed of the product in the inlet
area. Brush stations can be used to separate easily adhering products from the conveyer chain. Moreover, plungers mounted to the tooth flanks of the driving sprocket remove adhering or non-
free-flowing bulk materials stuck between the disks. The use of vibration or jet systems for the forced discharge of the products is also conceivable.


Inside the pipe system itself, the conveyer chain can also be equipped with oversized cleaning discs or brush discs, elastic sealing washers, or scratch discs. This will clean the pipe in the conveying as well as in the return path from the inside and helps to prevent product buildup.


However, the design with virtually no dead space at all, already ensures that no residues will
build up inside the conveyer system.

Conveyer technology for challenging products

The conveyer is gas, water, and dust tight and, due to its hermetically closed system, it is predestined for the transportation of challenging media as well as harmful or dangerous substances, regardless of whether they are abrasive, explosive, toxic, adhesive, or
chemically aggressive. This conveyer allows for odor free transport and is also available
in an ATEX compliant design for use in areas exposed to extreme explosion hazards.

Because, apart from the economic aspect, ensuring the safety of your venture is the key
factor in the planning of your conveyer system.
