Cage Drive A cage drive rests on a stationary column mounted in the center of the tank. A conventional center drive thickener. Typically, for minerals applications when the required diameter exceeds 75m, the TitanTractionTM thickener becomes economically viable. For diameters exceeding 100m, the TitanTraction thickener
EIMCO and Dorr-Oliver thickeners are available in both bridge-supported and column-supported designs. We offer beam- or truss-type bridges, depending on thickener diameter. In the bridge-supported design, suitable for thickeners up to 50 m in diameter, the drive is supported by the bridge, driving the rakes with a centre shaft.. Column-supported design drives are supported by a stationary
Jan 01, 2013· The shorter bridge compensates for the addition of the column and the use of a cage around the column to drive the rakes. Column types are economical, starting at about 40 m diameter, and are currently available up to a diameter of 130 m. Column type thickener. The torque required for the process is much higher than a conventional

Cage drive units are suitable for larger thickeners and can provide the torque needed in heavy-duty thickening applications. The cage drive is supported by a steel center column. These units transmit torque from a fabricated steel drive unit with precision bearing and gear through a center cage of box truss construction.

Such jumbo thickeners, when centrally driven, require for most demanding applications extra heavy duty drive heads some of which reach a continuous operating torque of 3.300.000 Nm. 150 meter Column Type Thickener handling phosphate slimes
undue stress on the thickener. All equipment needed to be also designed and fabricated with due consideration to sea freight and PNG road restrictions. In this regard, the drive cages were designed to be split into four segments and assembled onsite, such that they could be transported up the mine access road from the nearby town of Tabubil.
Drive Heads, HRSCC Drives, Motorized Lifting Device, Drive . We manufacture a wide range of Drive Heads that operates at a relatively low value of input power to give maximum value of Output Torque a Clarifier, Thickener or Degritting Mechanism Installation.Traditional System of using Drive Heads is still widely followed due to their competitive price and very high life expectency ranging from
Conventional clarifier/thickener Design Bridge type For smaller thickeners, up to 30 40 m diameter, the rakes and drive mechanism are supported on a bridge superstructure, which straddles
1. A thickener mechanism of the central column type having a plurality of rake arms with scraper blades attached thereto for raking the contents in a settling tank on rotation of said rake arms around said central column, said mechanism comprising a first cage supporting a first set of rake arms and being rotatable on said central column, driving means for said first cage, a second cage
These pressure transducers’ are best located in the cone or close to the center of the thickener. The transmitter should be located in a flanged spigot with the sensing face flush with the thickener surface. The measurement is usually very reliable and indicates the amount of solids in the water column
THE DRIVE UNIT IS THE MECHANICAL CORE OF CLARIFIER OR THICKENER THAT PRODUCES LOW SPEED HIGH TORQUE ROTATION OF THE SLUDGE COLLECTOR ARMS TO PERMIT POSITIVE SLUDGE COLLECTION AND REMOVAL FOR PROPER UNIT OPERATION. Cage drive column supported units; Dual cage drive for concentric cages and mixers; FEATURES:
A thickener according to the invention is provided with a mechanism for operating the rake arms of the thickener without the use of central drive columns and central drive mechanism but comprising a traction means including a plurality of spaced cable carriers distributed and mounted for movement along the peripheral wall of the thickener tank, cable means respectively connecting the outer
Circular Thickener Equipment: Center-Feed, Peripheral Overflow; Peripheral-Feed, Center Overflow Bridge-Supported Visual Sludge Removal (Uptake Pipe) Type; Column-Supported Scraper Type; Column-Supported Suction Header Type; Column-Supported Visual Sludge Removal (Uptake Pipe) Type 75 Zimmerman Drive, Camp Hill, PA, USA

Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below. High rate thickener feed wells are designed to disperse flocculants thoroughly into the feed end to admit the flocculated slurry into the settling zone of the thickener without destruction of the newly formed floccules.
COUNTER-CURRENT THICKENER CIRCUITS Drive heads and raking mechanisms are supported either by a full span or half span bridge arrangement. For larger diameter units (+45m), the mechanism is usually supported off a centre column. Drive units are either hydraulic or electric and include a full
The shaft drive unit is equipped with a rake lifting device, providing added mechanism protection and operation flexibility in an overload condition. Cage drive units are suitable for larger thickeners and can provide the torque needed in heavy-duty thickening applications. The cage drive is supported by a steel center column.
The drive unit rotates the structural steel cage attached to the internal gear & the two rake arms connect to the cage which rake the tank bottom twice per revolution. 5. The feed is let into the clarifier through the hollowed centre column at the bottom or feed pipe at the top.
Jul 31, 2020· In table II it is shown a Conventional thickener operation on which eventually evolved into the current deep cone thickener for paste production. This type of Column
An Ovivo cast-iron, oil-lubricated drive mechanism mounted on the center column supports and rotates a center cage with truss arms. Each arm supports plow-type or diagonal scraper blades. The blades transport the sludge accumulated at the bottom of the clarifier toward a
