Beginners guide to thickeners - Metso Outotec

16.06.2017· In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput. In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must …

HIGH RATE THICKENERS - McNally Sayaji

• The thicker underflowfrom a HRT implies that the rake mechanism operates at higher torque levels. This necessitates a robust drive arrangement and a failsafe torque sensing arrangement to protect the drive. The Drive arrangement in the MBE High Rate thickener comprises of a Hydraulic drive comprising of a hydraulic motor coupled to a

High Rate Thickeners - Solid Liquid Separation

High-rate thickeners that are built as dedicated machines are available in sizes up to 40 meter diameter but retrofits of conventional thickeners are often larger in size. When viewed from the outside high-rate thickeners look very much like conventional machines except that their tanks have a greater height to diameter ratio. Their height is derived from test work by calculating retention time and the reduced …

High Rate Thickeners - 911 Metallurgist

31.05.2018· How High-Rate Thickeners Work. High-Rate Thickeners separate liquids from solids using hindered settling. Rotating rake arms collect settled sludge and move it toward the center discharge cone. They use minimal amounts of polymers/chemicals to drop the solids, making High-Rate Thickeners environmentally friendly. Thickeners are operated and controlled by a touch-screen …

HiFlo™ High Rate Thickeners / Clarifiers ...

Sizing and Operating Thickeners - 911 Metallurgist

02.06.2017· Thickeners are often operated to keep the interface height constant using a level control device or manual measurements of the sludge level. In this case, if the feed solids rate is increased from 10.0 to 11.1 metric tons/day, the operating point at steady-state will move from point no. 1 to point no. 4. The underflow pumping rate will have to increase from 21.7 to 25.8 m³/day to remove the higher feed solids …

CHAPTER 3 SLUDGE THICKENING - Marmara

Generally thickeners concentrate sludge at lower than 15% concentration, the dewatering units concentrate the sludge to higher than 15% concentration [3]. Thickened sludge still behaves as a liquid and can be pumped. However, the dewatered sludge generally behaves as a solid and can be trucked in most cases. Operation of a Thickener A thickener operates pretty much like a settling tank. The ...

Thickeners - Solid Liquid Separation

The high time for thickeners was in the 60's when the metallurgical industries were booming and sizes of up to 150 m diameter were constructed. 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.

addition. High rate thickeners, as well as de-watering systems that use cyclones only or cyclones and high-rate thickeners can also be used in principle. Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas.

09.11.2019· Consequently, the in vitro-OTT of shear-thinning liquids is determined by their high shear rate viscosity (e.g. at 50 s −1) , which was much higher for the starch-based thickener compared to the xanthan gum-based thickener at high concentration (spoon-thick). We found that the apparent viscosities of the thickeners, prepared following the manufacturers’ recommended methods, did not always ...
