Conveying systems as individual as your requirements

Doubrava is a specialist for conveying systems that deliver a perfect flow of materials. Taking account both of our customers’ requirements and of the characteristics of the particular bulk material to be conveyed, we develop world-class stationary or semi-mobile conveying systems.

Since our company was founded, we have conveyed more than 2000 different bulk materials – giving us unique know-how in materials handling. Building on this know-how, our engineers establish the precise transportation parameters (using crushing tests, for example) for each new bulk material – for materials with grain sizes as low as 500 µ, if necessary. These analyses allow us to fine-tune individual components to create a system that is more efficient as a whole. The result: facilities with material flows that are ideal for their operating conditions.

Modular system design saves time and money

doubrava’s modular system design saves our customers time and money. Our components are standardized and normed, ensuring the preconditions for smooth operations. At the same time, this approach makes it possible to expand facilities step-by-step in the future. The high degree of prefabrication ensures their quality, as well as excellent value for money and short delivery times.

Perfect material flows thanks to our superior technologies

Time and again, Doubrava has proven the technological superiority of its conveying facilities – whether these are simple conveyor belts or complex complete facilities using pneumatic technology. Doubrava’s hallmarks are the particular care that we take in materials handling (evidenced for example by the individual material tests we conduct) and the technical know-how that we have acquired over the course of decades. The ongoing basic research and the individual research projects that we conduct ensure that our technologies continue to improve.
