Sludge settles in gravity thickeners and is compressed by the weight of its own solids. Primary sludge from the primary clarifier of wastewater treatment plants and digested sludge from anaerobic sludge treatment thicken better statically than secondary sludge because of the higher density of their solids.
Gravity Belt Thickening. Sludge must be pre-conditioned with polymer before it is sent to a gravity belt thickener. This conditioned sludge is applied to the belt traveling 2-10 ft/min. This belt speed can vary, …
Dynamic thickening is mainly used on lightweight, hydrophilic sludge: biological sludge and hydroxide sludge. Its main properties are the speed of the process and dynamic thickening ability to achieve good concentration performances on problematic sludge. The accelerated dynamic thickening of biological sludge is used to:

The Hycor ® ThickTech™ Rotary Drum Thickener (RDT) is the industry leading sludge thickener. Its performance is unmatched, with sludge volume reduction of 90% and a 98% capture rate. In addition, this superior performance is achieved with very low amounts of polymer. The RDT system is quite compact and requires less floor space than other ...
The practice of thickening or clarification is usually carried out in decantation tanks employing gravity settling or sedimentation. These tanks are fitted with mechanical scrapers to collect and move the settled solids to the point of discharge, the clear overflow being collected and removed by means of peripheral launders.

Thickeners can be widely used in the treatment of sludge, wastewater, and waste residues in metallurgy, mining, coal, chemical, building materials, environmental protection, and other industries. ... ball mill workshop, and other related workshops closely connected with the thickener, the thickener has a very important position and function in ...
Xinhai provides mineral processing technology, equipment manufacture and one-stop service for mineral processing plant, which solve many problems for mine investors. Xinhai equipment mainly include: ball mills, flotation, thickeners, and so on.
Overview of sludge thickening. A number of processes act purely to remove water from the sludge to reduce its volume. As a result, the suspended solids concentration of the sludge is increased, i.e. the sludge becomes consolidated.These processes are referred to as either thickening or dewatering, depending on the amount …
Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water …

Capacity: 1.3-1140 t/24h. Application: dewatering process of concentrates and tailings in the mineral processing plant. Our thickener is specifically designed for the mineral …
The speed of ball mill rotation is a critical parameter which determines the grinding efficiency and the end product quality. The optimum speed will differ depending on the mill's diameter, the size and density of the grinding media, and …
The two key operating parameters for gravity thickening are the sludge hydraulic loading rate (HLR) per unit belt width and the belt speed. The hydraulic loading rate is normally in the range 7−35 m 3 /h per m width, with an accompanying solids loading rate of 90−1600 kg/(m.h), at belt speeds ranging from 300 to 1200 m/h. Under such ...
Jaw Crushers. Designed to crush ROM feed material for demanding quarrying, mining, and demolition purposes. With their unique Elliptical motion of the swing jaw Crushers, ensure highly efficient production rates at any setting.
Ball mills use ~35% water for milling and in the discharge water is further added for separation in solids Most flotation operations are performed in between 25 F40% solids by weight. Some gravity concentration devices operate most efficiently on slurry containing 55 F70% solids. 20m min
6. Regular Sludge Removal. Over time, accumulated sludge or sediment at the bottom of the thickener can affect its performance. Regular removal of sludge through manual or automated methods is crucial to prevent build-up, maintain proper tank capacity, and ensure efficient settling of solid particles. 7. Lubrication and Mechanical Maintenance

Automatic De-Sludge facility. Back wash flushing system. Flocculent dosing system. Rake operation (rotating & lifting) by hydraulic system. Up to 95% process water re-usable.
True enough, a thickener doesn't make a racket like a ball mill, or spew out froth like a flotation machine, or bounce up and down like a jig, but down inside that big tank there is a lot going on just the same. ... The main idea in running a thickener is to get the sludge that comes out of the bottom of the tank as thick as you can, and, at ...
Thickening involves separating a slurry or mixture of solids and liquids into a concentrated slurry with a high solids content and a clear overflow. The separation occurs due to the …
