Estonia’s state-owned rail operator EVR Infra has appointed three aggregates producers to supply 180,000tonnes of crushed stone needed for repairs to the track bed on the Tallinn to Tartu railway line.

While Hurricane Katrina may be long gone, the repairs to flood defences around New Orleans in the US goes on and a mobile Hercules trammel screen is helping to meet the demand for aggregates for the work. A Stelex Construction Equipment manufactured HT182M is working in a quarry in Little Rock, Arkansas to process up to 500tonnes per hour for the work.

Demand for a mobile vertical shaft impact (VSI) crusher in Sweden has driven one quarry operator to customise equipment themselves.

While mobile crushers are designed to work in harsh conditions, it is the customers that really put the equipment through its paces day after day.

The customer was not only using the 32tonne machine to crush old toilets and glass but it was also performing well at this task.

Construction of a new highway across Morocco is placing high demands for aggregates along the route and Agregat Oued Cherrat is work to supply the project. Government investment in a modern motorway network in Morocco means the country is a hive of activity with around 1000km of route planned for construction in the next five years. The schemes have attracted contractors from around the world but the aggregates for the work are being sourced more locally.

Mild winter weather and stronger than expected recovery in Europe have been cited by Heidelberg Cement as the main driver of increased turnover in the first three months of the year.
