According to the working principle of twin roll crusher: wedge or gasket adjusting device is arranged between the two rollers, the top wedge device with adjusting bolt, the adjusting bolt when the wedge pulled up when the wedge will roll from the top fixed round of activities, namely two rollwheel gap bigger, the grain size becomes larger. When the wedge block down, movable roller wheels in the compression spring under the action of two smaller gap grain size smaller. The pad device by the number or the thickness of the pad to adjust the size of the grain size increases, when the gasket two rollwheel gap, when reducing the gasket two roll wheel clearance smaller grain size smaller.
Compared with the traditional hammer crusher and impact sand mill, the roller crusher said:
1.Power comparison. The roller crusher saves 50 to 70 meters.
2.Comparison of easily damaged parts: take quartz sand as an example, use hammer to break hammer head generally 2-3 days need to be replaced. Impact sand machine knife block also needs to be replaced within 5-7 days. The roll surface of the roller crusher can be used for a year and a half.
3.Comparison of crushing effects: in the case of quartz or machined sand, quartz sand usually requires a particle size of 20 to 120 mesh, using a hammer crusher or impact crusher, It is necessary to lose about 3 tons of powder when the rate of overpowder (less than 120 mesh) is over 30% or more than 10 tons of finished product, and the rate of crushing quartz sand in roller crusher is less than 5%.
