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, when reduce gasket will make two roller wheel clearance decrescent, the discharge size becomes smaller.

---Application
   Double roll crusher is suitable for crushing medium, high hardness materials in metallurgy, building materials, refractory materials. This series of crusher is mainly composed of a roller, the roller support bearings, compaction and adjusting device and the drive components.
   The grain size regulation: wedge or gasket adjusting device is arranged between the two roller, the top of the wedge device with adjusting bolt, when adjust the adjusting bolt will pull up the wedge, the wedge will move the activities roller from fixed wheel.
