·The thickening process is subjected to the feed flow and material quality perturbations parameters that require to be controlled The objective of control is to keep a stable % of solids in the thickener underflow discharge while the internal layers of clear water pulp interface and thickened mud bed layer figure 1 are kept in defined ranges and the
·Modernizing crucial mining and mineral processing equipment is key to meeting the sustainability aims of the sector and thickener technology is constantly evolving Retrofitting and refurbishing thickener equipment provides several benefits for the industry Firstly extending the lifetime of equipment saves costs and materials compared to
·Factors determining efficiency of Thickener Several types of thickeners have been developed and classified according to the arrangement of feed and discharge in the various compartments
5 ·Thickener troubleshooting in mineral processing plants involves identifying and resolving issues that hinder the efficient separation of solids from liquids One common issue is poor flocculation which can be caused by incorrect flocculant dosage improper mixing or changes in slurry characteristics Simultaneously energy management
·Under all conditions Thickener A offers the greatest efficiency advantage Figure 11 Efficiency versus oil temperature under highest torque Figure 12 Figure 13 Efficiency measurements were also plotted as a function of viscosity to factor out the effect of minor differences in viscosity among the various fluids
·Compared to the conventional and namely high capacity thickeners with motor driven rakes the newly developed high efficiency thickener has much higher unit handling capacity and much less maintenance due to its non moving parts and high thickening efficiency; industrial application of the new high efficiency thickener showed that its
However one of the main ways to create high efficiency thickener to increase settling rate of solid particles is flocculation In recent years extensive research has been carried out on the utilization of flocculant in isolated operations such as liquid wax paper industry mineral industry industrial water treatment and purification
·The feedwell is the heart of any thickener operation Mixing deaeration and flocculation are all performed and controlled within the feedwell structure So ensuring optimal design can result in efficient flocculation reduced reagent costs maximum underflow densities and improved overflow clarity
·The development of new generation of carbon dioxide CO2 thickener is significant to improve carbon dioxide flooding technology Here copolymers based on epoxide heptamethyltrisiloxane and glycidyl phenyl ether are prepared and their solubility and thickening ability in CO2 are evaluated The solubility of modified polyethers in CO2 remarkably
·The continuous accumulation of coal gangue without adequate storage and disposal facilities could lead to human health and environmental disasters in the long run [6][7][8][9]
·Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization The operation of the thickener must accommodate fluctuations control for disturbances in the process feed stream to deliver a clear overflow and thickened underflow
·Riyadh Saudi Arabia August 27 2024—Under the Patronage of the Custodian of the Two Holy Mosques King Salman bin Abdulaziz Al Saud Saudi Arabia is set to host the fourth edition of the world s leading platform on minerals the Future Minerals Forum FMF from January 14 16 2025 at the King Abdulaziz International Conference Center in Riyadh Saudi
·Large tanks known as thickeners are used to separate fine suspended mineral particles from the process water producing a stream of clarified water from the top of the thickener overflow and a thick sludge of settled solids underflow from the bottom which can lead to significant increases in thickener efficiency These efficiency gains
·The thickener in mineral processing is to concentrate the leaching liquid Compared with normal thickener efficiency thickener machine has significant advantages such as simple structure less land occupation low energy consumption and high working efficiency
·Factors determining efficiency of Thickener Several types of thickeners have been developed and classified according to the arrangement of feed and discharge in the various compartments For effective thickener control key considerations are bed mass inventory underflow density and flow bed level overflow clarity and flocculent dosing
Automatic control device for high efficiency thickener is a product that we developed through many yearsof practice it is a system realizing the interface relatively constant mainly through using the automaticdetection of flocculation layer in the thickener and the automatic controlling speed of underflow pump of the thickener which is converted from electrical is a high
·THICKENER EFFICIENT SOLID LIQUID SEPERATION AND ENHANCED MINERAL PROCESSING MINING EQUIPMENT Processing solutions from the technological leader Expertise GKD is a specialised supplier of Solid/Liquid Separation Equipment We have built an extensive successful reputation as a leading
·The common thickener underpins the performance of most hydrometallurgical facilities Thickeners are simple reliable effective and efficient under the right conditions
·Higher thickener feed flow rate also affected eductor performance reducing its discharge solid loading by 4 wt % Finally a smart thickener dilution system was proposed to maintain optimum dilution
·In summary improving the efficiency of a thickener requires considering multiple factors such as operating procedures process parameters flocculant selection automation control equipment
3 ·The overflow rate for gravity thickeners is calculated by dividing the flow rate of the liquid leaving the thickener by the surface area of the thickener It is a critical parameter that affects the clarification efficiency and is typically expressed in units
