Sand and gravel are mined from quarries, open-pit-mines or dredged from waters such as rivers, lakes, and seas. To transform the rough minerals into fit for use types of gravel, aggregate, sand, and for concrete construction, various production processes are required, including:

  • screening
  • crushing
  • washing
  • desalinating
  • sorting
  • fractioning

Depending on our client’s requirements, NM Heilig designs, builds, and installs purpose-made industrial equipment. This includes both the processing and classification of sand and gravel as well as the transshipment to sea ships, barges, railway cars, and trucks and storage at terminals.

Our technicians will gladly inform you about the multiple turnkey options we have to offer, including excellent electrical solutions for the optimal bulk handling of sand and gravel. Please do not hesitate to call us at +31 72 571 66 88 or send your email to

For the transportation, transshipment, storage, and treatment of bulk goods, NM Heilig builds and supplies both single units and turnkey bulk handling installations. Depending on the particular properties and the bulk density of the materials, bulk handling systems can process up to 6,000 tons per hour.

More than often, the systems require tailored engineering which may include: conveyors, screens and sieves, crushers, washing drums, mixers, desalination, classification, and fractions.

We implement strong and durable components only and aim for supreme bulk installations with a high throughput, efficient transshipment, and distinct treatment of bulk materials. Some of the materials are mentioned in the pages below.
