The spiral design of our thickener rake arm assembly offers a number of unique benefits that traditional rake arms cannot provide. By delivering a consistent, low-torque action in the high-density underflow, the spiral rake arm reduces power peaks and valleys, and reduces the ratholing that conventional straight rake arms can create.

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.

Thickeners, equipped with the patented spiral scrapers and angle rakes are a distinct improvement over all types of mechanical raking devices now in use. Specifications and thickener rake design All Thickeners have the same general specifications, varying only as to type of machine.

We custom design each conventional gravity thickener using customer specifications, standard methods, and computer software for proper sizing and drafting.

A key component of most thickener operations is the motion of a thickened sediment across the floor of the tank to an underflow, usually located centrally. In most conventional thickeners and in many high rate and paste thickeners, this transport is aided by a set of two or four rake arms (see the schematics in Fig. 1, Fig. 3).

Conventional thickeners are commonly used in applications where high solids concentration is not required. 2. High-Rate Thickeners. High-rate thickeners are designed to handle higher solids concentrations and provide higher throughput rates compared to conventional thickeners. They feature a deeper tank with a steeper floor …

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.

functional groups. These are commonly known as associative thickeners. In its simplest form, an associative thickener is a water-soluble polymer containing several relatively hydrophobic groups. HEUR's also belong to the category of associative thickeners. But unlike HASE's, HEUR's are nonionic substances and are not dependent on alkali for

Briefly, its functioning can be explained with Scraper blades or "rakes" that are used in a thickener, which rotate slowly over the bottom of the tank, and slope down towards the centre and ...

The term "conventional thickener" refers to those tanks with a shallow base slope and a relatively shallow depth of sediment, and is the type of equipment that is the focus of this study. Material that settles in a conventional thickener moves towards the discharge partly under the action of gravity and by mechanical transport using rakes.

We would like to show you a description here but the site won't allow us.

Gravity thickeners consist of a circular tank (usually with a conical bottom) that is fitted with collectors or scrapers at the bottom. Primary and/or secondary solids are fed into the tank through a center well, which releases the solids at a low velocity near the surface of the tank. ...
