Moisture in Ceramic Powder  

Control of clay powder moisture is paramount to the production of quality floor and wall tiles of consistent dimension.

Too high moisture results in a badly formed, flexible tile in the dry press, and too low moisture in easy breakage.

On line moisture measurement:
• results in tighter control of bulk density of powder and consequently more consistent product in terms of final dimension
• enables achievement of optimum moisture level minimizing wastage
• saves energy through not over drying

Tile Manufacturing Process
Clay, talc and other mineral constituents are quarried, refined, mixed and dried to a set moisture level prior to forming in a Dust or Ram Press at very high pressure. The formed tiles vary in moisture by as much as 6%, and must be oven or air dried to within 1%, prior to kiln firing. This prevents explosion of tiles within the kiln.

Gauge Installation
The sensor is located perpendicular to, and approximately 8” above a conveyor transporting the clay powder. Ideally the sensor should be viewing freshly turned product, so an ideal location is immediately after a conveyor change.
