When excess energy is available for transport (excess load height), the excess load must be dissipated.
The most commonly used system is energy dissipation rings, these rings are introduced into the interior of the pipe, restricting the inner diameter, causing a pressure drop. They are made of highly abrasion resistant ceramic material. How much charge loss does a power dissipation ring produce?
It is possible to dissipate up to 50 – 60 m of pulp velocities inside the ring of 30 – 35 m / s,
The loss of pressure in the hole, is:
H = loss of pressure (m)
Q = pulp volumetric flow (m3 / s)
D1 = inner diameter of the hole (m)
K = constant (0.075 – 0.80)
