Maple Aggregates Ltd - Importers and Distibutors of Specialist Minerals (Pumice Importer UK)

The natural lightweight aggregate

Yali Pumice is the product of volcanic activity from the volcano of Nissiros, which erupted 200.000 years ago. Quarrying of the pumice deposit at Yali is performed without using explosives.

Bulldozers feed a series of belt conveyors, screens and crushers, which pile the graded product onto specially formed stockpiles. There, a second series of belt conveyors are capable of mixing grades and can load ships of up to 30,000 tonnes, at a loading rate of 1,000 tonnes per hour.
