Grid Type Sieve
Materials broken down from the primary group may need to be sieved at different stages. In such cases, standard vibrating screens may not meet the required capacity and maintenance costs may be high. In KENSAN heavy-duty sieves, the upper layer is equipped with cast grate or Hardox-perforated metal sheet to prevent the large sized material – arisen damages and abrasions.
The grid type vibrating sieves are manufactured theoretically in 1 or 2 – storey one in every possible size dimension.
The vibration-resistant special bearings and the shaft housed in the sieve body are driven by the oscillation-adjustable weights installed at both ends of the shaft. There is an ellipsoidal vibration in the back and front sections and circular vibration in the center of the sieve. The vibration body sits on the main chassis with a sufficient number of heavy-duty type helical springs.
Generally, the product in the material crushed in the primary group is used to go directly to the product sieve without entering the secondary crusher. In this way, it prevents extra material to enter the secondary crusher and causes an augmentation in the capacity.
