The Creative High capacity Thickener has higher under flow densities and more water recoveries in comparison to the Conventional Thickener. Higher density requires more driving torque and also the rake should be lifted through higher viscosity material. .
Slurry particles drop through the settling room to the bottom of the thickener and the released supernatant rises counterflow to the overflow trough and is drained for further treatment. The overflow trough with an adjustable overflow level is created on the central cylinder or on the peripheral jacket.
The Stage #1 pump receives tailings slimes from the tailings thickener at a statichead pressure of 30 to 50 psig. The Stage #1 pump discharges at 60 to 80 psig into the Stage #2 pump, which discharges to the tailings pond at 100 to 190 psig.
area of the particles to produce lump free slurry [no fisheye in the case of thickeners and/or functionalizing ingredients]. The VACUCAM® Mixing Process achieves the ultimate dispersion with a single pass (no shear) process through the mixer.
thickener meaning: a substance that is used to make a liquid thicker: . Learn more.
The slurry settling characteristics are the most important to design a thickener in process industries. In this work, the iron ore slurry from the screw classifier overflow was used for the ...
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 Nm.
KETO Green Paper: Slurry Pumping 101 2017 Table of Contents . ... The value is determined by sifting the solids through screens with varying mesh and then weighing each fraction. A sieve curve can then be drawn and the percentage of particles of different sizes read. Example: d. 50
Jacques Pretorius, Minerals Africa's Pump Product Development Specialist, said the approach to solving any thickener underflow pumping problem must be based on a thorough understanding of the entire application, the mineralogy and rheological behaviour of the slurry. "Successful thickener underflow pumping projects are only achievable through involving a team of thickener engineers, .
The crosssectional area of a thickener, balanced by the slurry feed rate, determines the rise rate which is an important parameter in determining the clarity of the overflow. An inventory or depth of compressed pulp is maintained to reach the desired underflow pulp concentration.
The easiest and quickest thickening method, a slurry thickens almost immediately and creates a glossy appearance. To create a slurry, corn starch is stirred into a small amount of cold water or stock, then whisked into a simmering sauce. The same method can be used for nearly any starch; however, it's important not to overestimate the amount of starch you need, or to overheat the sauce.
The DPDM is used to measure the density of a variety of fluids and slurries. It is especially well suited on thickener feed lines where large bore piping is used in combination with low slurry densities.
The phosphate slurry is introduced directly to thickener feedwell placed in the center of the equipment with cylinderconic shape chosen to accelerate slurry sedimentation. The concentrated slurry is pumped out from the bottom of the thickener, while the water overflows from the top and recycled back to the previous steps of the process.
A thickener/clarifier drive unit supplies the torque to rotate the rake arms through the thick sludge. The drive is usually made of cast iron because of its durability. Usage Examples Thickeners and clarifiers are often used in water and wastewater treatment plants to
Welcome to Vietti Slurrytec Metallurgical specialists with clay and solid/liquid separation expertise providing dewatering and desliming process solutions to the mining industry
Thickeners are key unit in the Bayer alumina refining processing operations and are used to separate insoluble solid, usually red mud from the liquid feed slurry under the action of gravity. Thickeners enable the treatment of vast volumes of dilute feed slurry that passes through a . Get Price
