SUMMARY Rotor Spreader Hex consists of a hexagonal base (part 2 in illustration 1: Rotor Spreader Hex main components) of foam-filled HDPE plastic pipes with rounded corners. A transition in the base allows feed pellets to pass through into the aluminum tube (part 5 in illustration 1), and spread through the upper spreader part, with a rotating bearing. A swivel (1) is mounted in the transition between base and feeding pipe Union, to relieve torsional forces from inclement weather and waves. Between the bearing (part 4) and the base, three struts (part 3) are mounted, in order to maintain a...

The safest way to transfer a feed pipe from outside of the pen into the Rotor Spreader Hex placed inside the pen, is to lay the feed hose flat over the walkway and thread it through the jump net at the same height according to recommendations from the net supplier. This method is safest for personnel. The feed pipe may in some cases be thread just below the handrail, over the jump net, and attached to the handrail with rope or similar. If this method is preferred for the site, it is crucial to refer to the pen user manual to find maximal allowed load placed onto the handrail. Rotor spreader...

1 PRODUCT DESCRIPTION Rotor Spreader Hex spreads pellets with compressed air. By using Air Monitoring combined with Rotor Spreader Hex, with properties such as low friction start and high efficiency, the air speed can be reduced and at the same time achieve excellent feed spreading in the cage. The pipes are made of lightweight aluminum, which means that they require a lower air speed for start-up and rotation. This results in less dust and pellet breakage, power consumption, back pressure, noise, air temperature and wear on the feed hose. The Rotor Spreader Hex base is made of foam filled...

2 INTERFACE WITH OTHER PRODUCTS The safest way to transfer a feed pipe from the outside of the pen into the Rotor Spreader Hex inside the pen, is to lay the feed hose flat over the walkway and thread it through the jump net at the same height. If this method is to be used, implementation in nets shall be done in accordance with recommendations from the net supplier. It will be safest for personnel to move around the walkway if the feed pipe lays on the walkway and is threaded through the net/jump net. The feed pipe may in some cases be thread just below the handrail, over the jump net, and...

3 ASSEMBLY WARNING! Complete the assembly on barge/boat before taking the Rotor Spreader Hex to sea. If bearing bolts are tightened with incorrect torque, Rotor Spreader Hex will not function as expected. If the torque is too tight, the bearing will bend and may break. The assembly process shall be executed by qualified personnel. NOTE! Once the assembly is complete, it is important torque the tie bolts (part 10 in illustration 4: Rotor Spreader Hex parts 3/3) according to this chapter. The equipment must be handled very carefully during transport, and we recommend that two people take part...
