In the next sections, a detailed characterization of the worn surfaces of chute linings is presented, which facilitates better explanations of the wear processes taking place in an iron ore transfer chute and the design of reliable experiments that can effectively simulate the wear conditions and the wear modes and mechanisms produced in the ...

The full-scale validation consisted of comparing the final size distribution of material at the discharge belt of the transfer chute from the simulation using a commercial software (Altair EDEM) to results from an industrial survey, demonstrating reasonable agreement. ... Iron ore in nature exists majorly as fines, hence it is fed into the ...

In 30 years of providing modelling support to the industry, I have looking at hundreds of underperforming chutes in the iron ore industry. This practical experience has led to a unique …

For fast speed trajectories, the height of the bulk solid material on the belt at discharge, H, is generally equal to that at the last fully troughed idler set prior to discharge. ...

Spillages from feeders, chutes and conveyors must be minimized. Spill collection can be "designed in" on feeder installations; chute designs can minimize spillage at receiving and discharge points; and conveyor belts can be widened to be more forgiving (e.g., skirting internal

In the last few years, numerical simulations based on the discrete element method (DEM) have attained increasing influence in the chute transfer design process due to its suitability to model granular materials [20, 21].More recently, the DEM modeling has attracted much interest in industrial applications, followed by its accelerated performance by High-Performance …

Bulk handlers that routinely handle 'sticky' iron-ore fines often find these materials build-up, ... and less often with transfer chutes, that handle wet, sticky iron-ore fines. Fines flow properties are routinely tested in shear cells, measuring the stress at which the material yields (flows) over a range of consolidation pressures. ...

Chute flow patterns are described and the application of chute flow dynamics to the determination of the most appropriate chute profiles to achieve optimum flow is illustrated. The influence of the flow properties and chute flow dynamics in selecting the required geometry to minimise chute and belt wear at the feed point will be highlighted. 1.

rotating chute thatdistributes the iron ore and coke in layersuccessive s at the top of the burden (Figure 1a). The present study is focused on the behaviour of the particle flow due to the rotating chute, and hence a simplification charging syof the stem is considered. The upper section of the

Other than rules of thumb and basic calculations that are essential for any chute design, the DEM is a powerful tool for modelling and adjusting critical transfer points, while minimizing problems and operational risks.

The blast furnace is working on the counter-current principle. Descending solid charge meets an opposite current of ascending gases; due to that progressively heating and reduction of iron ore take place. The production rate of a BF depends on: (i) The rate of reduction of iron ore and (ii) The rate of heating of the burden.
