4.Dewatering operation of recovered minerals in composite iron ore. Flocculant is one of the ways to improve the efficiency of thickeners. The high-efficiency thickener adds flocculants to form large flocs in the pulp entering the thickener, which greatly improves the working efficiency of ordinary thickeners.
If the thickener has been left full of pulp but without operating pumps or rake mechanism, there is a serious danger of sanding, particularly after a number of hours of in operation. If the rakes are in the pulp, raise them slowly out of the pulp to their highest position by the manual lifting device. ... Thickener Normal Operation Procedure.

Underflow pumps and flocculant dosing pumps must be manipulated to control the thickener at the desired operation point in varying situations and quality targets. Whilst some classical techniques can handle these situations, regular operator intervention is required. The tuning becomes difficult, typically requiring high-level …
Valmet Gravity Thickeners are devices that use gravity and a rotating drum to thicken pulp and reduce water content. They are designed for all pulp types and applications, and offer high capacity, low cost and easy …
The thickening process is the primary method of producing high solids slurries for the minerals industry. Thickener outputs can accommodate a range of tailings disposal …
The simplest use of a thickener in a metal-mining operation is to get water out of a pulp; for example, in a desert country where water is too valuable to be thrown …
Clarifiers and thickeners are separation devices, common in waste treatment as well as in other chemical operations. These devices separate two phases by differences in their density. Clarifiers and thickeners are essentially identical units; a clarifier produces clean water, while a thickener concentrates a solids slurry as the desired product. A …
Control Actions for Thickeners. There are different targets to optimize thickener performance: To ensure optimum solids content in the tailings impoundment, an underflow density target is used. …
A thickener is an equipment structure used for the continuous gravity settling (sedimentation) of solids in suspensions. Suspension is fed into one or more basins or chambers and, whilst it is passing through, the solids settle out. The thickened solids are removed together with a portion of the liquid as thickened "underflow".
The excellent and reliable thickening performance of the gravity drum thickener is based upon 50 years of pulp dewatering experience. The PRS Drum Thickener is a simple, cost-efficient, and reliable filter for dewatering stock and broke, as well as for and recycled fibers in a consistency range of 0.5–5.0%.
In this way, with the help of Decker Thickener, the pulp is thickened and stored in the chest. As Washer for: – Used for removing excess water & increasing stock consistency – Provides flawless & reliable operations – All water & pulp contact areas are made with SS – Improved design of sealing arrangement to minimum fiber loss
As mentioned above, dewatering operations utilize it substantially. The utilization of a high-efficiency thickener for red ore integrated by centrifugation can achieve greater underflow concentrations and raise the dehydration velocity of the concentrate. ... A cylindrical tank houses the continuous thickener. Pulp is supplied into the tank's ...
It is possible to establish two modes of operation for the clarifier-thickener depending on the location of the critical concentration ... Determine the optimal flocculation dose for a pulp entering the thickener. The instrument has six main components: Tank for storing and homogenizing the pulp.
Paper Pulp Inclined Screen is mainly used in paper pulping process for pulp thickener, it's widely used in paper making mills for its excellent function. ...

Table of Contents At start-up, the relatively high level of feed solids, 17-20%, called for in design led to difficulties in achieving the degree of flocculation necessary to meet required settling rates. It was recognized that decreasing feed solids would improve thickener performance while reducing flocculant consumption (Figure 2). This was …
This work used mathematical and numerical modeling to study the influence of such parameters as the flow rate of the feed pulp in the thickener, the flow rate of the flocculant, the density of ...
Fig. 11 The Dorr Thickener. The slime pulp entered by a launder stretching from end to end along the centre line with small holes bored at intervals for the exit of the pulp, and the clear solution …
Combined with a flow meter, the mass flow can be calculated, giving real-time insights into the efficiency of the thickener operation. In mineral processing operations, water is very important and therefore water recovery plants have an important position.
Thickening of mineral processing products is the process in which the solid and liquid in the pulp are relatively separated, so as to obtain the thick pulp with …
The measurable parameters that can be used for thickener control include thickener feed flow rate, feed density, underflow density, overflow clarity, bed level, bed mass, rake torque, rake height, solids settling rate and underflow rehology.
Thickeners are designed to operate continuously with slurry/water consistently flowing into the centerwell with thickener underflow pumping balanced to maintain a mud bed in the thickener. Key to thickener operational efficiency is the solids must be able to settle 2-4 times faster than the nominal water up flow rate.
