High efficiency screening is considered to be one of the key factors influencing the asphalt plant performance. The “semi-inclined” SIGMA screen combines the advantages of horizontal screens and inclined screens as per the latest technology. The linear oscillating motion of the screen is generated by two vibrating motors with adjustable counterweights.
The screen is equipped with bypass and oversize material chutes automatically controlled from the control panel. Aggregates can be separated into 4, 5 and optionally 6 classifications. The sliding front chute and larger back doors facilitate easy screen mesh replacement.
