A French SME is offering taylor made design and production of high hardness and density metallic mini balls for powder grinding and mixing. It is looking for partnerships with ceramic parts producers to develop and produce adapted balls for specific high quality powder mixes under technical cooperation or with grinding equipement makers under manufacturing agreement.



This French SME has developed a know-how and equipment to produce 100 % pure tungstene balls with very high hardness and density. Starting from diameter 0,1 mm, these mini balls are used in powder grinding. The company is able to study, design and produce balls adapted to different powder specifications.
The mini balls can be used for grinding but also for mixing of powder with particular applications in the ceramic sector where powder quality is required for complex parts.
Their technical characteristic provides a significant improvement in the grinding quality and they also last longer which reduces costs for the end-users.

It is now offering this know-how to co-develop with ceramic powder end-users taylor-made balls according to their own specifications under technical cooperation agreement first and manufacturing agreement after. It is alternatively offering manufacturing agreement to grinding equipment manufacturers requiring such balls.

Advantages & innovations

Cooperation plus value: 
- very high hardness level (2700 Vickers). - the mini balls are inert, non-magnetic, stainless. - very high density (15.6 g/cm3). - better wear resistance and grinding efficiency thus the quality is significantly improved compared to the balls widely present on the market.
