This series machine applies into crushing middle hardness material in cement, metallurgy, chemical, electricity, power industries etc, finishing medium-fine crushing like limestone, furnace clinker, coke, coal etc. It can be divided into several single roller, doubles rollers and multi-roller. According to the tooth surface the machine also can be divided into smooth roller and tooth roller.

The two rollers have wedge or gasket adjusting device, wedge device with the top adjustment bolt, when the adjustment bolt wedge block upward pull up, wedge will activities roller top from fixed wheel, two roller gap becomes larger, the discharge size becomes larger, when the wedge block down, activity roller compression spring (or pressing oil cylinder) under the action of two gap becomes smaller, the discharge size becomes smaller. Gasket device is through increase or decrease the number of gasket thickness to adjust the size of the discharge size, when adding gasket will make two roller wheel gap bigger, reduce gasket will make two roller wheel clearance decrescent, the discharge size becomes smaller .
