Unnathi Groups Technology Reinvented

HP Crusher Backing compound

100% solids epoxy compound having high compressive strength and impact resistance for backing wear plates in primary crushers, large gyratory crushers and cone crushers for extreme heavy duty crushing. It is safer and more economical than conventional zinc backing. Also used for grouting of new machinery or replacing old grouts for making solid and perfect foundations, which resist high loads and vibration.

Surface Preparation :

All metallic parts should be free of rust, dirt, grease, oil etc., Seal all voids and gaps to prevent leakage. Coat bowl liners, threaded portions with '" Unnathi' ‘ Release Agent for easy removal.

Mixing :

Stir Resin box individually for at least 3 minutes using slow speed stirrer to disperse any settlement that may have taken place during storage. Add entire contents of Hardener slowly but continuously to Resin while simultaneously stirring the Resin. Move stirrer up, down and around the sides of container till achievement of uniform colour.

Application :

Pour mixture from one place to fill the cavity to avoid air gaps. Use tin sheet or cardboard to direct the flow if required. Repeat the procedure for succeeding kits.
