A more sustainable solution where the liners last vastly longer, prolonged uptime and fewer liners are used. The curved internal profile of the Wearback chute controls the speed and material flow from top to bottom. Material is guided through transitions to align with the outgoing conveyor and soft load the material centered onto the receiving ...
Towards the development of design criteria for reduced wear in iron ore transfers. Conveyor system wear of belts and transfers attribute to a significant proportion of the maintenance costs and lost productive hours when handling hard abrasive ores at high unit rates typical of the….
This paper comprehensively analyzes the transportation of iron-bearing solid materials in industrial-scale transfer chute stations by a GPU-DEM model. It considers five chute head designs, including the traditional rock box, impact plate, and hood, as well as the modified micro-boxed alternatives to the impact plate and hood.
The primary function of a transfer chute is to reliably transfer the bulk material at the specified rate of flow. If the material will not flow reliably through the chute, then meeting any or all other objectives is irrelevant. Bulk materials should flow through a transfer chute evenly and consistently. A transfer chute that places surges of ...

The successful performance of the transfer chute is also dependent on operating with a "robust range" of material flowability and handling characteristics. This requirement is crucial in accommodating minerals ores from developing resources which are often more friable and stickier than in past decades.
Abstract. The Discrete Element Method (DEM) is increasingly used to analyse the design of conveyor systems. In this study, the capability of, and accuracy with which DEM can predict the flow of a non-cohesive granular material through a transfer chute was investigated. The model included a Chevron patterned belt, an impact plate, …

Dust emission becomes critical at specific locations, such as transfer chutes and stockpiles. This work models the dust generation that occurs in an iron ore pellet stockyard using a methodology ...
An engineered transfer solution can control spillage so effectively that it makes a skirting system optional. A transfer system without skirt rubber can operate effectively for 5 to 10 years with ...
Copper, iron and other hard rock mineral ores utilize the rock box principle to control the flow of primary crushed ore in the transfer chute, typically -200 mm open side setting.
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 ...
The dryer feed chute of the pellet plant plays an important role in the pelletizing process. The chute discharges sticky and moist iron ore fines (1 mm) to the inline rotary dryer for further processing.Since the inception of the installation of the dryer feed chute, the poor flowability of the feed materials has caused severe problems such as blockages and …
The transfer chutes were commissioned by late 2016. "Both transfers with all products, including fines, are operating blockage free and are loading central on to the receiving belts at the iron ...

The transfer chute will act as a funnel, constraining the maximum throughput of the conveyor system, and must be sized accordingly. Consider both weight and volume per hour and ensure there's ample capacity. Once constructed and installed there's no easy way to increase the volume a transfer chute can handle.
Although responsible for only a relatively small fraction of the CAPEX, transfer towers and chutes are often responsible for significant challenges and down-time in the operation of ore processing plants and port facilities. In the past, these critical components of the conveying system have been designed using standard tests and methods, which do not …

The worn linings were obtained from an iron ore transfer chute in an operating mining plant to be analyzed to study the wear mechanisms responsible for short lifetimes. Two linings that were under sliding and impact conditions were designated LSSA and IA, respectively. A top view image of the LSSA lining is displayed in Fig. 3 (a). A …
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. ...

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 …
Fines Ore – Transfer Station | Gulf Conveyor Systems and Transfer Chutes. Material: Iron Ore. Status: 2013. Solution: StallFlow Chute and SmartFlow Deflector. The particular chute allows for fine wet-sticky material (-8mm) at 16,000tph. This provided a significantly improved surcharge angle on receiving belt compared with previous chute and ...
Main chute problems. Chutes are frequently overlooked during the design stage of the conveying systems, which can lead to the following issues: Material build-up and blockages causing unscheduled stops. Material spillage and degradation. Health and safety risks for operators when deblocking or housekeeping spilled material and carryback.

In Chute Sample Cutters. Falling stream sample cutting in chutes gives the most representative samples. These sampling systems add complexity in almost all aspects of chute system design. They affect ore flow design, need extra space and chute height, need maintenance access and add a sample discharge in an already congested area.
This transfer chute at an iron ore port processing facility was originally lined with metal wear liners. The highly abrasive material wore through these metal liners prematurely and unpredictably, leading to costly production loss as the parent metal began wearing through to cause ore spillage and loss of chute availability. With the use of ...
