The application of chromite sand

Chromite ore fines has good increasing friction effect in low and high temperature, plays a dual role too. Added to rubber can play a good role of increasing friction, and do not scratch the duality and noise. In the friction material commonly used in chromite fines Cr203, content of 25%-40%, the higher Cr203 content, increasing friction effect is bigger. Use should pay attention to controlling the amount and particle size. Proper dosage should not exceed 7%, particle fineness more than 200 projects. Excessive dosage and coarse grain size can improve the friction coefficient but also will cause friction increases obviously.
