NJIT Licensee Invents Industrial Process For Grinding Cement And Other Cementitious Materials
Flyanic (www.flyanic.com), a cementitious mineral processing technology company and licensee of NJIT, has developed an industrial scale and affordable process for grinding cement, fly ash, and other cementitious materials to a median particle size of one micron. The processing costs range from $30-75 per ton, depending on feedstock, and they can be scaled to industrial levels of production using proven equipment.
Flyanic, along with its development partner, grinding-mill equipment manufacturer RSG Inc. (www.ultrafinegrind.com), recently applied the NJIT technology to the design of a vertical-stirred media mill to perform the pilot scale demonstrations.Cementitious materials ground to ultra-fine particle sizes have significant benefits in a range of industrial applications, including specialized grouts for oil and gas exploration. Fly ash and slag, finer than 10 microns, are high reactivity super-pozzolans for building products such as high performance structural concrete and pre-cast concrete. A one micron median fly ash product has not been previously available on an affordable industrial scale.
