Thickener Torque -Rakes & Drive

A little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT. As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque. Each rake arm is higher at its far end than it is where it joins the drive shaft. This is designed this way to give the bed a slope towards the centre of the thickener

Beginners guide to thickeners liming Outotec

16/06/2017· It should be remembered that both the thickener rakes and the underflow pumps (or valves) transport the thickened underflow. The size of the solids inventory determines the bed depth and the residence time that solids will experience in the thickener. This, in turn, determines the underflow slurry rehology and the water recovery to overflow. Generally, operators directly manipulate the

The tip speed of the outer blade at 1 rpm corresponds to the same tip speed as that in a 40 m thickener operating at a rake speed of 3 rev h -1 . A variable frequency drive was used to control the rake speed either by manual setting or by utilising the on-board programming capabilities.The study was undertaken at a sand mining operation, with the clay-based feed (all sub 100 μm) being drawn

RAKE IN THE BENEFITS ON YOUR THICKENER AND KEEP ITS

The rake arms, along with the thickener drive, are at the centre of a thickener operation. Rake blades apply the . force required to keep solids flowing to the thickener’s centre. They also assist in slurry dewatering by providing a shearing force that allows entrapped water to escape. Since the entire thickener operation depends on its ability to continuously move dense underflows (up to 70
