◊ The pneumatic shipunloaders of Van Aalst Bulk Handling BV can be devided in two groups:

◊ VAST type - which means "suction only" machines

◊ This type of shipunloader sucks the cement out of the ship or river barge and drops it into a bulktruck or on a belt conveyor which is located near the shipunloader.

◊ VASS type - which means "suction / blow" machines

◊ This type of shipunloader sucks the cement out of the ship and blows it to the storage facility. Both parts of the process will be executed by the equipment which is built as one complete shipunloader. Only a pipeline has to be installed between the shipunloader and the storage facility.
