The original thickener mechanism consists of a central drive shaft, two long rake arms, and two short rake arms, both with strut supports and tie rods "tying" the four arms together. The rake arms have scraper blades to move the material inwards, struts to give the arm vertical support, and tie rods to distribute the torque load evenly ...

Shear Rate – the velocity gradient or the rate of change of velocity at which one layer passes over an adjacent layer is the shear rate, γ = dv/dx = [units = s-1] Viscosity – this is expressed mathematically as, η = shear stress/shear rate and is the measurement of the resistance to fl ow of a fl uid. Pascal.second
The feed well of the Hi-rate Thickener Contains a special Flocculation Chamber & the feed enters this Chamber a hollow Drive shaft. Creative High Rate Thickener can be used in variety of different applications – including Mining & minerals, Industries, chemical, Water recovery, Water treatment and waste water Industries.
Raking plays a major role in transporting solids to the underflow discharge point and increasing the solids concentration in a thickener or clarifier. The main purpose of a thickener or clarifier is to separate solids from liquids. A thickener achieves this goal by stimulating the release of as much liquid as possible from solids in the underflow.
How A High-Rate Thickener Works. How It Works Videos McLanahan High-Rate Thickeners help producers reduce settling ponds or tailings storage facilities by recovering clear process liquid. They can be an on …
HIGH-RATE THICKENER. High-rate thickeners also have a smaller tank volume, so less volume is required for storing the product if the tank has to be emptied. Because of this, high-rate thickeners can start up and shut down faster than conventional thickeners. However, due to their smaller size, high-rate thickeners require faster settling rates.
High compression thickeners Achieve a higher density underflow with our High Compression Thickener. The HCT has been designed to suit customer needs with a deeper solids bed and higher rake torque than our High Rate Thickener or conventional thickeners. Consistent and high-density underflow Maintains a constant solids …

Measurements Bed level and bed mass can be measured to help determine flocculant dose and underflow pumping rates for efficient and stable operation ...
High-rate thickeners operate under strict constraints and several disturbances. To control this process, a constrained model predictive control (MPC) is developed in this paper. For process identification, a historical data-driven methodology is used and a vector autoregressive with ex ogenous variables (VARX) model structure is …
High rate thickener units are provided in sizes ranging from 5' to 250' in diameter, and can accommodate drive head torques of up to 4 million foot pounds. They are available in shaft or cage driven models. Shaft drive …
Our High- Rate Thickeners are specially designed to recover water from the slurry for re -use. Thickeners are the future as due to water scarcity; it has become mandate for us to save water not only for capital saving but for our future generations to enjoy the benefits of it and keep the environmental stable.
High-Density Thickeners are similar to High-Rate Thickener but include additional features to increase underflow density and liquid recovery. These features include higher side walls and a steeper …
The evolution of Outokumpu's rake mechanism is a case in point. The original thickener mechanism consists of a central drive shaft, two long rake arms, and two …
High rate thickeners are designed specifically to maximise the flocculation efficiency of flocculants. They differ from conventional thickeners in feed well design, size and …
The main components of a high-rate thickener are the overflow launders, the rake arms, and the discharge cone (Fig. 1). These components are linked to the process constraints. At overflow, the turbidity must not exceed a certain limit, as well as the rake torque and the pressure at the discharge cone, in addition to the bed level which must ...

PHOENIX HiFlo™ High Rate Thickeners clarify wash plant effluent water while thickening the slurry to 40-45% solids, greatly reducing the underflow slurry rate to the slurry pond. PHOENIX Thickeners use sedimentation technology to maximize the water recovery rate, providing clarified overflow water that can be recycled and reused in the ...
To my mind in a high rate thickener, solids concentration during flocculation is a powerful tool and we have to choose the solids concentration to achieve maximum flux concentration. In this condition selecting a safety factor would led to overcome variation in feed properties (e.g. solids concentration) and a wise design would be achieved. ...

In high-tonnage applications, traditional rakes (shown right) do not provide enough raking capacity to move mud evenly to the outlet. Instead, the low-density material ratholes, flowing directly toward the outlet without optimal time in the thickener. A common challenge with traditional thickener rakes is their inability to move mud evenly to the
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 …
The function of the High-Rate Thickener is to increase the density of a sludge stream. This is done by introducing the sludge into the settling tank and allowing the solids to settle. The clean water overflows for reuse or disposal. The settled solids are collected in the central cone of the decanter or clarifier and are disposed of as ...
