Langhagen gravel works with its moraine gravel deposit is located on the A 19 road around 50 km outside the city of Rostock, Germany. Around 1 mill, t sand and gravel are processed at the works annually. Besides concrete aggregates, the plant produces high-grade asphalt aggregate and base course materials. The gravel deposit contains boulders up to 1200 mm in size. Some of these are used in gardening and landscaping. The smaller boulders to 700 mm in size are crushed in two stages and screened into different gravel chipping fractions. Cost-efficient primary crushing of these boulders is a challenge for every processor - and also for the Langhagen plant owned by Heidelberger Sand und Kies GmbH.
