Oval Screen

Introduction& Advantages

NFLG oval screen, firm in structure, unique fish-shaped frame support, oval motion track, three-layer side arm box increases the maximum stress area, suitable for coarse grain screening, natural aggregate and crushed aggregate fine sieving ,which has the characteristics of good sieving, large processing capacity and low installation height. It is an ideal equipment for various mines and quarries.

  • The overall structure is compact, easy to install and repair, and low operation and maintenance costs.
  • Large processing capacity, not easy to block holes and materials, smooth screening of materials.

Stable and efficient

Using oval running track, the length, angle and amplitude of the moving track can be adjusted to avoid the bumpy motion of the screen box of the straight running track, the running is more stable and the screening effect is good.

long lasting

There is a unique labyrinth seal in the bearing end cover, and non-contact rotation enhances the service effectiveness and service life of the seal.

High precision

It can screen a wide range of materials, easy to screen fine materials, powder materials, high screening accuracy, and low mixed screening rate.
