Spray granulate

Spray granulate/press granulate/ceramic masses

Spray granulate to manufacture building components and moulded bodies according to the dry pressing process. We produce spray granulates with Al2O3 contents of 92 - 99.5% as well as customer-specific special masses.
Our plants can also be used to prepare and spray dry ceramic masses to our customers' requirements.
