Transfers from conveyor to conveyor, chutes feeding to conveyors and chutes discharging from conveyors are all systems that have multiple functions. The primary chute function is to contain, direct and deliver bulk material at a nominated rate to a receiving conveyor, bin or stockpile. Containment includes dust and cleaner discharge.
This large surface area facilitates the reduction of iron ore to DRI; however, it is prone to generate significant fines during handling and storage and encourages reactivity with oxygen when exposed to air and water. ... Transfer chutes are a necessary component of a material handling system because material must be loaded onto and discharged ...
A qualitative modelling case study is presented investigating the sensitivities associated with transfer chute design geometry and the resulting chute and belt wear life.
Chute liners, transfer chute lining, Wearback, Xledge, conveyor lining. Keeping transfer chute downtime to a minimum is one of the biggest challenges in the mining and aggregate industry. Menu Close About us. …
While a range of different transfer chute designs were tested during the course of the experimental test program, Fig. 2 shows two of the scale model chutes tested. These chutes are labelled A and B and include; A – baseline case, B – a chute with an inbuilt restrictor plate in the vertical leg, in addition to the lower removable cover fitted …
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 …
Blocked chute detection in a Mining process application is crucial to the operational performance of the site. Hours lost to downtime caused by a blockage in a conveyor transfer chute can take hours to clear, which in dollar terms can mean thousands of dollars in lost production and a delay in production schedules.
Transfer chute is used in many industries to facilitate bulk material from one conveyor belt to another or for guide flow from a delivery point (feeder, screw conveyor) into a process or equipment ...
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.
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. ... Development of design criteria for reducing wear in iron ore transfer chutes. Wear (2019) D. Ilic et al. Modelling bulk solid flow interactions in transfer chutes ...
The purpose of a rock box is to prevent the flow of ore from wearing out the bottom of the transfer chute. TRANSFER CHUTES OVERVIEW. Transfer chutes are primarily used at the transfer points in a conveyor system. Therefore, they need some type of feature, such as a rounded base that will allow the chute to discharge its load into a centralized ...
At Palabora's copper ore mine in Northern South Africa, enhanced transfer chute geometry has substantially improved belt life (ref. 3,4,5, and Fig. 1c). Now, nine years since the first hard rock curved chute was applied, the belt is still in operation. Modified chute geometry has increased belt life 300%,
A common form of platform or "Chinaman" chute is illustrated in figure 69 at A. Strictly speaking, it is not a chute at all, the ore is held back by an offset, as shown, a car is run underneath, and the ore is …
In the particular case of iron ore sinter, whose handling occurs only inside the steelmaking facility, transfer chutes occupy a central role. This important material-handling operation has been ...
There are two principal types of wear mechanisms associated with bins and chutes in iron ore mining, namely, the impact wear and abrasion wear (Roberts et al., 1989; Tuckey, 2003). Impact wear occurs when bulk material exhibits oblique to normal angular contacts with the wall lining materials at relatively high speeds (Scott and …

Successful performance of transfer chutes in belt conveying systems requires adequate design to allow re-direction of the primary flow stream via an impact …
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 and unbiased perspective on chute design and their performance in the real world. ... Iron ore transfer chutes – directions after 30 years of scale modelling ...
• FIG 16 - Detail of trajectory in contact with delector, and discharge into bin. ACKNOWLEDGEMENTS Jenike & Johanson for their involvement in the Bulk Terminal Saldanha Bay iron ore chute redesign. BMEA and DEM Solutions for their involvement in the product coal transfer chute, the subject of the second case study.
One of the most popular topics in the bulk solids handling world is the appropriate design of transfer chutes for effective plant operation and reduced downtime. Transfer chute problems are by far the most common we deal with in our engineering projects, which involve the design or re-design of transfers and associated work, …
Iron ore plugging would occur several times per shift, requiring operators to use high pressure water hoses to unplug the chute. At times, the iron ore was bone dry and dusty, leading to severe dust generation during handling in the chute. The iron ore is highly abrasive and would wear parts of the transfer chute that did not experience …
This paper will include details of chute installations associated with iron ore and coking coal, from the DEM simulations through to the performance of the installed and …
Transfer chutes for bulk materials are designed for durability, reliability, and safety, but dust control is critical. ... Skirts are heavy-duty rubber strips that fill the gap between the bottom of the discharge chute and the lower conveyor. Adjustment is critical to minimize lower belt wear while keeping dust within the chute enclosure ...
In comparison, lumps were observed to discharge directly onto the fines layer which were in already present on the chute surface, before exiting the contacting zone. ...

or through a device called a transfer chute (Figure 8.1). This chapter covers conven-tional transfer chute design. Because each material and each ap-plication has its own characteristics, an effective transfer chute must be more than just a hollow vessel through which mate-rial is channeled. A well-designed chute
The successful performance of the transfer chute is also dependent on operating with a robust range' of material flowability and handling characteristics. ...
