VIRINA Steel Nano Technology Grinding Balls:


The first turnkey product VIRINA is offering are VIRINA Steel Nano Technology Grinding Balls for the Cement and Mining Industries. The consistent hardness from surface to core of the VIRINA Steel Nano Technology Grinding Balls provides an industry changing competitive advantage over the current products in the marketplace.


VIRINA Nano Technology Grinding Balls have received rapid acceptance in the Cement Industry in Taiwan and China during the initial product release and this success is highly anticipated to continue throughout the worldwide Cement and Minining Industries. VIRINA is now the fastest growing supplier to the US and Mexico grinding market in 2016 with continued worldwide expansion underway.



VIRINA Grinding Ball Benefits and Test Results:


VIRINA Steel Grinding Balls are made by using a proprietary combination of alloy elements to create a high carbon steel. Billets of this steel are forged while using a proprietary heat-treating and cooling process. This process provides the high impact, minimal deformation and extended wear properties of VIRINA Steel Grinding Balls.
