Grinding Media

Ceramic Grinding Media and Mill Linings

Grinding Media: CerCo is the ceramic industry's global solution provider offering a complete line of grinding media and mill lining products. Grinding media are available in many formulations: 87-99% aluminum oxide, vitrified silica Porox™, zirconium silicate Zarsil™ and zirconia Zirmonite™.

Outstanding Electrical and Electronic Properties: CerCo Structural Ceramics have extremely high electrical resistance, won't support combustion and resist tracking. The high thermal conductivity of these materials quickly dispels heat. Our proprietary 99.5% alumina ceramic, developed specifically for microwave applications, has a dielectric constant of 9.8 at 1 MHz, a dielectric strength up to 300 v/mil and a Q factor that can exceed 48,000 at 1800 MHz in PCS resonator assemblies.

Wear Resistance: CerCo Structural Ceramics are hard (9+ on the Mohs scale, second only to diamond), with excellent resistance to wear by sliding abrasion or erosion.

Extreme Temperature Stability: CerCo Structural Ceramics remain mechanically stable at all temperatures with no cold flow, and maintain strength at continuous use temperatures over 2000° F (1093° C). In certain cases, intermittent operating temperatures can even reach 3000° F (1649°C) without permanent material damage.

Resistant to Corrosion and Chemical Attack: Most CerCo Structural Ceramics do not oxidize and are highly resistant to attack by corrosive liquids, acids, alkalis, organic solvents, molten salts and molten metals.

Gas and Liquid Tight: CerCo Structural Ceramics are 100% impenetrable by liquids or gases, making them ideal for hermetic applications.

These formulations are used for deagglomeration, mixing, and particle size reduction of such products as:

  • Minerals
  • ISO 9002 certified manufacturing.
  • State-of-the-art diamond grinding (finishing) and measuring capabilities for tightly toleranced parts.
  • A staff of ceramic, mechanical and electrical engineers ready to help solve your problems.

Whether we can adapt an existing product or develop a new one for your need, you can count on CerCo Structural Ceramics. For more information on the following applications call (330) 567-2145.
