Abrasion Resistant Rotary Airlock Valves Prater

Prater Abrasion Resistant Rotary Airlock Valves last longer and reduce costs Prater Abrasion Resistant Rotary Airlock Valve is the preferred choice for highly abrasive or corrosive products. The rotary airlock's ceramic lined cast iron housing achieves better performance than airlocks made of solely of cast iron, stainless steel, or Ni-hard.

May 08, 2014Cryolite usually comprises 75 to 80 wt% of the molten electrolyte, which typically also contains excess aluminum fluoride (9% to 12%), calcium fluoride (4% to 7%), and alumina (2% to 4%). These three additives lower the melting point of the electrolyte, as well as the cell operating temperature, and they increase the efficiency of the process.
