Application: Cracker mill is used for the breaking process from used tire scape to rubber powder. Advantage: Strong Quality Machine & Higher Capacity Features: The rollers are made of chilled cast iron or casted steel(surfacing hard alloy) with wear-resistant hard surface. The two rollers are grooved. The bored rolls can be cooled homogeneously through inputting steam and cooling water. The two rollers rotate reversely with different speed, so that rubber material can be processed.
