Bulk material handling in the building industry

Complete solutions for transporting and feeding your bulk goods

Bulk material handling in the building materials industry entails several challenges. For the production of plaster mixtures, for example, different transport systems for bulk materials are required in order to provide cement and lime in large quantities. At the same time, the systems must be suitable for high dosing accuracies, a wide variety of recipes and frequent product changes when producing mortar mixtures.

Our experience with pneumatic transport systems or mechanical conveying installations makes us experts in turnkey solutions that effectively combine emptying, dosing, feeding, mixing and filling.

Challenges in building materials


Bulk material is often used in large quantities. Filling into such large containers means that filling stations have to guarantee a high filling capacity and be as automated as possible.

Find a solution


The ability to empty bulk materials that do not flow easily, such as chalk, must be guaranteed. At the same time, dust emissions must be minimised to optimise the working conditions for the employees.

Find a solution


Many abrasive products, such as sand, have to be conveyed over long distances. The dosing of the main and small components must therefore take place quickly, but still with high accuracy.

Find a solution


Due to the specific requirements for mortar and plaster, the number of formulations is constantly growing. In order to respond to this challenge, the feeding systems must be flexibly expandable.

Big bag emptying for ten collection points


For the project, 30 big bags per hour had to be filled with sand fully automatically.

The solution

  • The empty big bags are gripped fully automatically from a stack by a robot and fed to the filling station.
  • The filling process, the closing of the big bags, the feeding of the pallets and the removal of the filled big bags are also automated.

The emptying of big bags and sacks in a common system.

The solution

  • Big bags of plaster are placed on the top with a forklift.
  • Additives in bags are emptied into the same chute via an integrated bag chute.

The aim of the project was to produce different mortar mixtures in spatially confined, existing conditions.

Die Lösung

  • The project includes the EMDE Bulk Batch System, various conveying and dosing systems and the necessary mixers.
  • The feeding and dosing equipment has an automatic transport system for containers

Conveying of limestone and gypsum over a distance of 120 m from big bags to 10 different locations.

The solution

  • The big bags are placed on one of the dischargers with chain hoists and filled into the pressure transmitter with a capacity of 1500 L.
  • Three conveyor stations are individually connected to one of 10 conveyor lines via a hose coupling station.
  • An air generator with refrigeration dryer is available for each station.
