Efficiency of raking in gravity thickeners
Existing literature on raking includes the work of Warden (1981) who investigated sludge transport in a water treatment thickener and approximated the effect of a set of uniform rake blades by replacing them mathematically with a continuous spiral. He developed a mathematical model of the sludge discharge speed as a function of rake speed and blade …

Thickener Torque -Rakes & Drive
As the load in the thickener settles to the bed, the Torque on the rake arms will be climbing. Torque is nothing more than a rotary force being applied from the rake arms to the drive shaft. It is the degree of torque that indicates to the operator the load that is in the thickener and when the rake arms have to be lifted.

Difference Between Clarifier and Thickener
The dense Thickener solids are raked to the thickener's underflow cone and are removed via a slurry pump through the underflow pipe. Underflow slurry densities can vary based on the type of material being processed, size distribution of solids being settled, or other process factors but as a general rule, range from 35-50% solids by weight.
Gravity Belt Thickener
As a gravity belt thickener manufacturer and a worldwide gravity belt thickener supplier, Vortex Engineering provides large variety of design options. Gravity belt thickeners are designed to thicken the sludge that comes from the picket fence thickeners. A flocculating polymer is used for further thickening and obtaining a sludge cake at the end.
Thickener Spiral Rake Blade
We build our spiral rake assembly for thickeners in a high-strength tubular construction that in and of itself will enable an increase in underflow density of 2 to 3 wt%, compared with traditional box-truss construction.

Mill Feed Thickener Operating Principles
Prior to starting the thickener, the rakes must be raised. Once the rake drive is started, the rakes can be lowered with the gear mechanism. Should the rake drive be started after lowering, or the process material be too dense, an impending high torque situation will alarm at the mill control panel annunciator at 40% torque.
