Our total annual production capacity is 60,000 tonnes.
Delarue S.A.S. sells approximately 50,000 tonnes of pebbles per year, of which 90% are exported (360 foreign customers in 63 countries).
Our pebbles are used as a grinding ball into ball mills (ceramics industry).
The high silica content (over 98%), the purity (only 0.016% of Fe2o3 ) and the hardness (8 on the Mohs scale) make this a pebble of an exceptional quality, with a worldwide reputation in the ceramics industry.
The dimensions produced, in centimeters, are as follows, but on specific request from customers, we are able to produce special qualities (balls, light or dark colour for example). |
