High efficiency screening is considered to be one of the key factors influencing the asphalt plant performance. The latest technology “semi-inclined” SIGMA screen combines the advantages of horizontal screens and inclined screens. The linear oscillating motion of the screen is generated by two vibrating motors with adjustable counterweights.

Aggregates can be separated into 4, 5 and optionally 6 classifications. The screen is equipped with pneumatically controlled bypass deviator valve and oversize material chute as standard. The sliding front chute and larger back doors facilitate easy screen mesh replacement.

A pendulum service crane above the screen is also delivered as standard for maintenance and lifting up the screen meshes.
