Characteristics of the New Double-roll Crushers

New double-geared roller crusher is very promising in outdoor coarse crushing because it involves the advantages of compact structure, reasonable crushing mechanism and good adaptability into one.

The following are its main features:

1) the crushing roller has the characteristics of low rotate speed, little abrasion, low noise and little dust.

2) the foundation design is very simple and due to applying monolithic structure and the drive reducer connecting to the crushing frame directly, the force reaches to the foundation reduces greatly. On the other hand, the equipment has slight vibration so that it is suitable to locate on the mobile crushing plant.

3) adopting the specially designed gear reducer with strong overload ability which can adapt materials well. Compared with common roller crusher and feeding crusher, the double-geared roller crusher can crush materials with great hardness and can crush viscous materials as well because the crossed layout of the long gears makes them comb mutually.

4) employing long gear, small roller diameter, spiral cloth tooth and polydisc four teeth structure, and by cutting, bending and squeezing to crush materials which is more reasonable in mechanism than common . In addition, the stress on the crushing gear is smooth and the allowable feeding strength is big, so it is particularly suitable for coarse crush.

5) equipping the crushing bar under the two crushing rollers forms the three-level crushing process between the crushing gear and the crushing bar. And the crushing ratio is high, the discharging granularity is uniform and the granularity size can be adjusted.

6) the equipment has compact structure, flexible layout, small size space. Besides, the crushing height is small so that it can low the overall layout height effectively and reduce the construction cost of the crushing plant greatly.
