AltaFlo ultra high rate thickeners perform well as tailings thickeners, in CCD circuits, as concentrate thickeners, and in leaching circuits. The low CAPEX economics of an AltaFlo also make it a perfect solution for dewatering non profit streams. The heart of any thickener or clarifier is the feedwell.

The inlet stream going to a thickener generally is called feed or influent. Overflow from the unit may be called 'overflow, effluent, or supernatant. Underflow may be called pulp, sludge, slurry, mud, etc. The terminology will depend upon the industry application.
Thickener technology and flocculant performance have advanced as water balance and conservation demands on projects have increased. This paper discusses the changes to testwork and design methods that are required for thickeners and flocculants to successfully produce
However, since paste thickeners are commonly chosen for applications where underflow density (rheology) is the key design criteria, alternative considerations, such as overflow clarity or flocculant consumption, may be less important and willingly compromised for lower capex or layout.
As the leading manufacturers of professional thickening equipment in the world, Xinhai has successfully developed various types of rake thickener, deep cone thickener and tilted plate thickener, which perfectly achieve free sedimentation among 20 3500 and fully meet different demands of all kinds of ores and production sizes.

Flotation Concentrate Thickeners. The thickener can be driven by belt and pulley from a line shaft, but it is more satisfactory to employ an individual motor for every thickener, mounting it in the superstructure and fitting it, if necessary, with a speed reducer.
Actually, thickeners simply concentrate the solids, achieving underflow solids densities from 20% solids to 50% solids. Typical thickener feeds range from 2% solids to 10% solids (by weight). Feed enters the thickener near the center, below the water level. Gravitational acceleration causes the solids to fall towards the bottom of the thickener.
Beginners Guide to Thickeners. 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 also be selected to ensure the desired underflow density from the thickener is achieved.
Separation is effected rapidly because of the system hydraulics, which can be in excess of twenty times the hydraulics of conventional thickeners. As a result of the innovative design and associated hydraulic efficiency, the plant area for the HiFlo high rate thickener is greatly reduced, even making indoor installations practical.
Solids discharge from a thickener are typically in the range to 25% solids by weight up to 50% solids by weight (for thickeners used for concentrating solids). In addition to the tank, conventional thickeners have rakes, which slowly push the compacted solids towards the
This is particularly the case with thickening of flotation concentrates, in which air bubbles The accumulation of froth on the surface of thickeners is a common problem air . including the type and concentration of frother, frother collector interaction, bubble
inlet stream to a thickener, usually a dilute slurry, is known as the thickener feed, while the decanted solution is referred to as the overflow. The concentrated solids slurry pumped away from the thickener discharge cone is referred to as the underflow (Figure 2).
In order to deal with corrosive slurry, we also develop the anti corrosive type thickener. The center drive thickener is mainly consist of thickener tank, rake, rake drive, rake lift, feeder, discharge cone, overload indicating or alarming device and etc. This machine has the features like simple structure, low wearing and convenient maintenance.
NZ Center Drive Thickener. NZ center drive thickener is a traditional thickeners with a history of earilier application. Our NZ thickener is applicable for small scale thickening. The diameter of our NZ series thickener is under 20m.
Deep Bed Paste Thickener Overview The original concept of the deep cone thickener was developed in the 1960s using a steep angled cone and thickener bed to increase underflow density. Over the years, this thickening technology has evolved to produce a non settling solids suspension with underflow concentrations much higher than
McLanahan Thickeners can be used as stand alone solutions or used in conjunction with other equipment, such as Hydrocyclones, Dewatering Screens, Pumps and Filter Presses. How Thickeners Work. Feed to the Thickener enters from the feed tank to minimize air entrapment.

The High Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high rate machines. Furthermore, they are normally positioned far away from
Working principle . Deep cone thickener is a machine that based on gravity and sedimentation which makes solid liquid separate from each other.The concentration of pulp waste water could be enhanced from 2%~ 15% to 60% ~ 70% by the machine, the clear water is overflow from the upper part of the thickener , so as to achieve the purpose of sewage purification and solid liquid separation.

Difference Between Clarifier and Thickener. Thickeners are used to concentrate solids, while clarifiers are used to purify liquids. A thickener will give you a high density underflow while a clarifier will not. The clarifier overflow is typically cleaner or clearer than the thickener overflow would be.
