SuperScreener - Operating Principal

• A bed of rotating stars mounted on hydraulically driven shafts transport the material to be screened.
• During material transport, fines are removed by passing through the spacing between the fingers, and the spacing between the fingers and the next star shaft.
• The oversized material rides on top of the star deck and is transported off the end of the star deck and onto the oversize pile.
• The screening size is not only determined by the spacing between the stars, but also by the speed the rotating stars are driven.
• The rotation speed is easily adjusted to allow changes to the screening size, thus allowing multiple screening sizes with one screening deck.

Advantages

• The star screen deck spreads material quickly and tends to pull it apart.
• Higher processing capacity, particularly with traditionally difficult materials.
• Adjustable star deck speed allows multiple fractions with one star size.
• Heavy-duty construction means making adjustments to the screening deck between screening operations is no longer necessary.
• Reduced operating noise. The star screen uses soft stars not loud vibrating or shaking components.
• No shaking or vibrating means less wear.
• The sloping screening deck means less space requirements.
• Stars are easily replaced and have an average life of between 2,000 and 3,500 hours.
• Star bed utilizes "component" design to facilitate changing.
