Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
In addition thickeners are an economic means for of process waters Clarifiers are extremely efficient for treatment of waters The MIP Process Corporation thickeners consist of the following basic parts each of which is supplied in a number of variations to best suit a particular application Tank Drive unit and optional lifting device
·The feedwell performance in gravity thickeners and clarifiers relies on the efficient mixing between solid particles and flocculant to achieve effective flocculation as well as energy dissipation
·The flocculant control resulted in less flocculant usage whilst keeping a stable interface reducing flares and ultimately reducing costs associated with overuse of flocculant Fig 2 Performance trends during thickener shutdown and start up
·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 The specifications given for one will cover all
·A study is made of the effect of the final density of the pulp in the pulp thickening operation on the quality of the final flotation product at the Talnakh Concentrator Plant The effect of the reagents that are used on the flotation process is thoroughly analyzed The main relations which express the dependence of the quality indices of the finished concentrate on the
·6 High rate thickeners Thickeners and clarifiers Metso Outotec High Rate Thickeners include a number of innovative features in design Our Directional Autodil and Turbodil systems auto dilute feed while optimizing performance and flocculant consumption Our innovative Metso Outotec Reactorwell
·As the expectations for more consistent and higher density thickened and paste tailings in the minerals industry increase so do the demands on flocculation performance within gravity thickeners Low solids feed suspensions are delivered at a high velocity to center feedwells which not only serve to dissipate the feed s momentum and evenly
·To investigate the effect of flocculant dosage on the settling flux function a series of batch settling tests were conducted at various flocculant dosages for unclassified and fine tailings
·Methods were studied and proposed to help determine the optimal dose of flocculant in a copper concentrate ore and thus have more information to contribute to the improvement of the use and recovery of process water in thickeners which currently values of 75% recovery of this vital element are reached
·The thickener high efficiency thickener generally consists of a thickener tank a truss a transmission a truss lifting device a feeding device a discharging device and a signal safety main feature of the concentrator high efficiency concentrator is to add a certain amount of flocculant to the slurry to be concentrated so that the ore particles in the
·In processing gold nickel iron copper ores etc thickeners are used to produce overflows suitable for use as process water in circuits such as flotation The clear overflow water is used for re pulping the flue dusts or fine dust from precipitators Therefore the feed to thickeners vary considerably
·To avoid this adjustable flocculant spargers are provided so that the flocculant can be dispersed into the feedwell at the optimum level This level is often very close to the outlet from the feedwell Autodilution is now operating on many thickeners in Australia and a number of thickeners are operating with this system in other parts of the
·Conventional thickeners also known as sedimentation thickeners are the most basic type They consist of a large cylindrical tank with a central feed well and a peripheral overflow launder The feed suspension enters the tank through the feed well and the solids settle at the bottom while the clarified liquid overflows from the peripheral
·Another important design parameter is the total height of the thickener which consists of the raking supernatant and sludge zones DWA M 381E recommends a minimum height of m for the raking zone and about m for the supernatant depth of the sludge zone is most important as it defines solids retention time
·large conventional type thickeners This leads to a situation where many thickeners are running under conditions far from the optimum meaning high flocculant consumption limited capacity poor underflow density and high solids in the overflow At Sentinel Mine the tailings thickeners were suffering from all of the above and even very high
·When this happens the rest of the De watering circuit will have to shut down While the circuit is down there will still be feed coming into the thickener from flotation and the concentrate will still be settling This means that the rakes will have to be kept turning to evenly distribute the concentrate over thickener bed
ANDRITZ is able to offer a wide range of thickeners and clarifiers with diameters from 1 to 70 meters Along with an extensive range of construction materials efficient flocculant shearing in the feed pipe Evenflow feedwell The newly improved feedwell reduces turbulence by
·I heard of turbidity measures being used for floc addition in wastewater treatment but I have no direct experience with it I work in mining application where the important factor is sludge density instead of overflow clarity and we typically use ultrasonic bed level measurement and underflow density nuclear gauges
·However most solid phases readily take up any polymer present For flocculant to reach an overflow at an appreciable level is a sign of incredibly poor operation extreme overdosing inadequate flocculant dilution and very poor mixing hydrodynamics The exception may be in clarifiers where feed solids concentrations are low
·variable feed • Reduced flocculant consumption • and cost • Reduced operator time for manual work Application The Thickener Optimizer controls Concentrate thickeners Thickened tailings Paste thickeners CCD loops Partner for positive change Metso Outotec Töölönlahdenkatu 2 FI 00100 Helsinki Finland tel 358 20 484 100 fax
·Froth on concentrate thickeners is a common issue faced by many sites For every 2200 ppm and 75 m3/hr of overflow approximately 4 tonnes per day of concentrate is either lost or recycled back into the operation The recycled flotation concentrate is less likely to be recovered each time round reducing overall recovery Scope
·The thickeners underflow density and overflow clarity increased with raising the slurry pH and flocculant dosage as well as distributing the flocculant solution at different locations along the feed stream The proposed modifications were accompanied by a reduction of 23% in the total water consumption corresponding to an annual savings of
·This paper reviews the design and application of paste backfill in underground hard rock mines used as ground support for pillars and walls to help prevent caving and roof falls and to enhance
·There are 4 types of thickeners in mineral processing plants rake thickener efficient thickener tilted plate thickener and deep cone thickener
·With the addition of flocculant commonly by polymer solution particles in the feed stream will be aggregated into large size of flocs which settles fast under gravity to produce a clarified
·The dewatering of tailings is one of the serious challenges that the mining and mineral processing industries have encountered internationally Solid liquid separation methods are applied to wastewater which generally consists of fine particles and water; fine particles are settled in thickeners by the flocculation method and the cleaned water is reused in the plants
