2020-10-19 design data for thickener. CHAPTER 3 SLUDGE THICKENING . 22 · The design involves selecting a typical solids flux and calculating the required surface area by dividing the anticipated solids feed by the flux [3]. Area of the thickener: 2. Design based on Iaboratory data First Approach: It is the best technique if the Iaboratory data is available.

2016-3-4 design calculations to determine the required thickener area, the most important design parameter, and ultimately the maximum steady state underflow concentration that is possible for a given solids throughput. In addition, the capital cost ofa thickener will be dependent on the calculated required settling area. Therefore,

Thickener design configuration s usually consider the high rate or paste thickener options, with a tradeoff between capital cost and process performance. Design s that assume a

The data set used for data analysis contains data from both of Yara’s paste thickeners, but after discussions with plant experts the data analysis was limited to Thickener 1. The whole data set contained altogether 73 measurements from February 2017 to February 2018. The frequency of measurements wasone per minute.

2021-4-9 FIG. 7.46.2 Gravity thickener design data plots. Data plot procedure: 1. Conduct settling tests at various initial solids concentrations (a through d in panel A), covering the range of expected thickener influent solids concentrations; 2.

1991-3-1 An important implication of these results relates to thickener design and the determination of settling area. If the design underflow concentration is 300kg/m3 for a thickener which is to be fed at a volumetric rate of 4m3/s and at a feed concentration of 5 kg/m3, a significant difference in the calculated vessel diameters using the three flux curve methods is obtained, as shown in Table 1.

2016-3-8 Thickener area required is then calculated by applying above determined data in the following formula: A = 1.333 (F D)/R A = Thickener area in square feet per ton of dry solids thickened in 24 hours. F = Initial density (Parts Water to Solids by weight).

DESIGN OF ' THICKENER CIRCUITS. Introduction Feed dilution or solids-liquid weight The English word "sedimentation" ratio is derived from the Latin verb "sedere" Size and shape of the particulate meaning to sink down. As a mineral solids processing unit operation, sedimentaSpecific gravity differential between tion has been defined as the

2012-3-22 Similar to the digesters, there are two design approaches in thickeners too: 1. Design based on experience. 2. Design based on Iaboratory data. 1. Design based on experience Solids throughput is an important criterion in the design of thickeners. The design is mostly based on the solids flux, i.e. kg solids/h/m2. Typical flux values are given in Table 2.

The data set used for data analysis contains data from both of Yara’s paste thickeners, but after discussions with plant experts the data analysis was limited to Thickener 1. The whole data set contained altogether 73 measurements from February 2017 to February 2018. The frequency of measurements wasone per minute.

As a mineral solids processing unit operation, sedimentaSpecific gravity differential between tion has been defined as the separation the solids and liquid phases of a suspension into a supernatant presence of

In this chapter we analyze different methods of thickener design that have been proposed in the literature, in the light of their physical foundations. We distinguish three types of methods: (1) those based on the macroscopic balances, (2) those based on kinematical models and (3) those based on dynamical models.

Feedwell Design. By employing Computational Fluid Dynamics (CFD) modelling, test work and our experience across more than 35 years of thickener supply across 46 countries, we know what works and doesn’t! Our latest generation feedwell design was released in 2017 Boasting improved flocculation together with ﬂocculent and slurry kinetics

Thickener outputs can accommodate a range of tailings disposal options from low yield stress, easily . pumped for informed use of data for design or optimisation.

2015-7-1 MIP Thickener Design The following is a short cut to designing your own thickener: (a) Size of Thickener As a first stab we can either use the thickener flux (m. 2 /tpd) or the rise rate, depending if solids loading is the dominant (eg.

Design tools. Our application specific design of the thickener begins with the use of design methods such as Discrete Element Modelling (DEM) to examine solid particle movement within the thickener, and Finite Element Analysis (FEA) for structural steel design.

Thickener design errors In thickener design, there are two specifications that will define the tank efficiency to process minerals: thickener area and drive torque. These specifications commonly have high variability and are required to adjust to the programmed processing tonnages during the life of the mining project.

2019-12-9 Design based on Laboratory Data; Design based on Calculations; Design based on Industry Construction Standards and Methods; Design based on experience is based around Solid Flux. Solid flux is the Settling velocity multiplied by the Solids Concentration. The area of the thickener is then found by dividing the Anticipated Solids Feed by the flux.
