Thickener rakes are essential in the transport of sediment bed material to the underflow in conventional thickeners, however very few studies of bed transport have been published.
Historically, improvements in the performance of industrial thickeners have been based on selecting conditions that produce desired properties in settling test behaviour, such as the free settling rate, final sediment solids concentration, viscosity or shear yield stress.

Current Trends in Countercurrent Decantation and Thickener Circuit . The Manta CCD/Thickener Cube is made of two parts 1. the Manta Underflow Cube, normal measurements of rake torque, bed pressure and underflow density to understand and speed 13 MW wraparound drive.
Thickener Torque Rakes amp; Drive. View Larger Image; 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. In a plant where sliming thickeners are a problem you may find a device to determine at what depth that the interface is at in the thickener. The best that I
The rakes convey underflow sludge to the discharge point and thicken the sludge by creating paths in the compressed zone, which allows escape of entrapped liquid upwards. High Rate Thickeners Perhaps the most significant design optimisation effort in thickening in the last twenty years has been in developing ways to more effectively use the
Two structural steel rake arms are connected to the centre shaft. The rake arms are provided with blades and adjustable brass/neoprene squeezes to rake the tank bottom twice per revolution. The rake arms are also provided with specially designed vertical pickets for efficient compaction of sludge.

Typical designs of thickeners are sketched in Figure 11.6. The slurry is introduced at the top center, clear liquid overflows the top edge, whereas the solids settle out and are worked gradually towards the center with slowly rotating rakes towards the discharge port at the bottom center.

Sludge rake arm is provided with adjustable brass/rubber squeezes for proper sludge
Although thickener rakes are essential in the transport of bed material to the underflow in conventional thickener designs, and effective rake design and operation can reduce the likelihood of rat holing, little is known about transport due to rake action in thickeners.
Thickeners are used in continuous process applications where liquid solid rakes and feedwells are custom designed, based on the feed conditions and raking capacity. A retrofit service is the settling area. The rake blades, attached to the tubular, low drag rake arms are designed to the raking capacity required for the treated

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 thickeners centre. They also assist in slurry dewatering by providing a shearing force that allows entrapped water to escape.
Types of dewatering equipment covered are Thickeners (Gravity) A thickener is a machine that de waters slurry, separating the liquid from the solids. The solids' particle size range in thickeners is generally from 0.5 mm to a few microns. The finer the particle size, the slower settling and compaction rate. The rakes slowly rotate, with
Types of dewatering equipment covered are Thickeners (Gravity) A thickener is a machine that de waters slurry, separating the liquid from the solids. The solids' particle size range in thickeners is generally from 0.5 mm to a few microns. The animated graphic at right shows the rotation of the rake mechanism in a thickener. The rakes slowly

Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away. On abrasive applications the rakes and blades are subjected to a significant wear so it is good practice
