E Cat® ultra high rate clarifier and thickener With its rakeless design the E Cat uses novel technology to accomplish both clarification and thickening in a single unit that takes up minimal area High density thickeners By adding depth and torque to a high rate design high density thickeners improve underflow densities at a substantially lower
The retention time in a High Rate Thickener HRT is less than 3 hours and surface area is relatively small and hence CN losses are negligible which is not necessarily the case in conventionally sized thickeners Auto Dilution A significant development by Supaflo has been the Auto Dilution facility Since most CIP tailings pulps are
The solid components of CPB are mainly made up of uncemented thickened tailings UTT and deep cone/high rate thickener DCT/HRT which are usually employed in the thickening process The performance the torque of the rake of the thickener is significantly affected by the rheological performance of the tailings
Sedimentation RICHARDSON BACKHURST in Chemical Engineering Fifth Edition Volume 2 2002 The thickener The thickener is the industrial unit in which the concentration of a suspension is increased by sedimentation with the formation of a clear liquid In most cases the concentration of the suspension is high and hindered settling takes place
High Rate Thickener; Dewatering Screen; We at PAIMINI EQUIPMENTS believe that quality and customer experience is the key for overall enhanced customer experience We believe in pushing the boundaries of innovation to create products that inspire and elevate the human experience PM HRT Our High Rate Thickeners are specially designed to
4 High rate thickener units are provided in sizes ranging from 5 to 250 in diameter and can accommodate drive head torques of up to 4 million foot pounds They are available in shaft or cage driven models Shaft drive thickeners can be truss or beam supported for heavy duty applications A heavy duty drive unit with precision bearing and gear
The underflow density of DCT around 100 250 Pa is much larger than high rate thickener around 10 30 Pa It could obtain minimal storage areas maximum underflow concentration from mud bed and maximum clarified water recycling [66] [67] [68]
The HRT S is a pre engineered range of high rate thickeners providing the same performance metrics as the HRT but with selected needs with a deeper solids bed and higher rake torque than our High Rate Thickener or conventional thickeners Consistent and high density underflow Maintains a constant solids inventory and solid/liquid
Let us assume a 35M high rate thickener being driven by three kW 10 HP motors Installed power then is kW We will further assume an alternate
125m high rate thickener The challenge expands As a result of this success between 1997 and 2001 the same customer requested we design the same thickener but with an increased DRT In response we offered a 125m diameter high rate HRT high density HDT & deep cone thickeners DCT under construc
Metso is launching a pre engineered high rate thickening solution the HRT S which will allow significantly shorter delivery times The HRT S complements Metso s existing High Rate Thickener product family which consists of the HRT and HRT S products The HRT S thickener is a part of Metso s Planet Positive offering enabling savings in power consumption

Comprising of High Rate Thickeners High Compression Thickeners Paste Thickeners Clarifiers Polymer Dosing Units they fit seamlessly to other dewatering units like filtration or any type of water treatment applications Compared to traditional delivery Thickenings Plant Units result in the earliest time to volume 3
Beneficiation of coal is a water intensive process and the water is recovered in downstream operations in the high rate thickener HRT and vacuum belt filtration VBF Clean coal particles entering the HRT have an inherent tendency to enter the overflow because they are extremely fine and hydrophobic Hence flocculants polymers are used to floc the ultrafine
2 The HI RATE THICKENER is a MechProTech OEM product manufactured in house It has a structurally grated walkway across the top To aid settling and thickener performance MPT can install high circulating pumps to increase supernatant back into the feed stream to improve the thickener s floc generation and settling performance
Maximising the density at the deposit minimises the volume required for storage Over the last three years we have continued to engineer and supply large diameter tailings thickeners into copper projects in South America including the following high rate HRT high density HDT & deep cone thickeners DCT under construction as of Q4 2020
Aesha Make High Rate Thickener for efficient Water recycling process method in Mineral & Recycling Process Industry Available in range of 50 000 Liters to 2 00 000 Liters per hour capacity Applications Solid Liquid Sepration Plant Recycling Water from Sand/Mineral Beneficiation Process Effluent / Sewage Treatment Plant
By these means the settling process is accelerated and consequently High Rate Thickeners achieve a significantly higher throughput per unit area than conventional thickeners The object of a control system on a High Rate Thickener HRT as on a conventional thickener is to obtain the required underflow density and overflow clarity at all feed
Metso launched its latest pre engineered high rate thickening solution the HRT S which will allow significantly shorter delivery times The HRT S complements Metso s existing high rate thickener product family which consists of the HRT and HRT S products The HRT S thickener is a part of Metso s Planet Positive offering enabling savings in power
