AusIMM Iron Ore Conference, 2013, Australia Abstract Frequently materials handling operations are compromised by transfer chute problems ranging from high wear rates, blockages and ineffective loading of the downstream conveyor.
Transnet's iron ore export terminal at Saldanha, South Africa, has undergone a series of phased expansions over the past few years. Phase 1A, which ramped up capacity from 29 to 41mtpa, was largely completed prior to Hatch's involvement in 2006. ... One such problem was the stockyard conveyor discharge chutes, which experienced regular ...

Strategically positioned at a 30º angle, a series of Martin Engineering air cannons keep material flowing at a Michigan nickel mine previously plagued by chute blockages. When needed, a single worker can perform …
The iron ore bulk density is about 2.5 times lignite, and is to be taken care accordingly. This means material momentum component creating sticking as well as its component resisting sticking, both will be 2.5 times. If you are handling iron ore (-) 100 mm then solution can be similar to lignite (use appropriate liner to withstand more abrasion).

The cement manufacturing process involves the handling of raw materials, such as limestone, clay, and iron ore, which are then crushed, ground, and mixed to form the final product. Throughout this process, material can accumulate and cause blockages or build-up in equipment such as silos, hoppers, chutes, and kilns.

Ore is stored in a covered coarse stockpile facility prior to transport to the Humboldt mill. A former iron ore processing plant, the Humboldt facility's three-stage crushing circuit reduces the material to 3/8 in.-minus, then a single stage ball mill grinds it further to sand, where it is mixed into a slurry.
Installing point detection devices in transfer chutes for blockage detection is necessary …

The special design avoids any material blockages and ensure very high discharge volumes of up to 9,000 tons of iron ore pellets per hour. Double-deck vibrating screens with 2 exciters The heart of the screening plant are the six double-deck vibrating screens, each with a width of 3,000 mm and a length of 9,200 mm.
Wet-sticky LD iron ore of high Al 2 O 3 % were cohesive at 8% to 12% moisture. ... hoppers and chutes as and when required (Fig. 2). ... flow was restricted by the severity of events such as cohesive bridge formation and blockages that cause subsequent jamming of discharge openings frequently. Consequently, unreliable flow …
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 …

The nature of adhesion and cohesion is however quite complex, according to Roberts [2] a study of this subject would require a detailed understanding ...
"To prevent future blockages we've carried out Fine Element Analysis on the chutes to determine the flow of the iron ore and verify the chutes' capability to handle 10,000 t/h and to load this material central to the ongoing conveyor." Both projects will be completed by the end of August 2012.
The Humboldt mill, a former iron ore plant, has three-stage crushing that reduces the material to –7 mm followed by a single stage ball mill. This is followed by selective [TE1] flotation. Fines are screened out, falling into a wide-mouthed hopper, leading to a chute that narrows to approximately 2.5 metres wide by 0.6 metre high and, after a ...
The testing methodology is based on a specialized procedure that involves compacting iron ore samples at various moisture levels to simulate the real packing conditions expected in bunkers and chutes and then subjecting the samples to a shear test using a Jenike-Schulze Ring Shear Tester (RST-01.pc).

Chute Technologies. Falling resource prices mean producers must step up production to survive and flourish. But some coal and iron ore producers are finding that their efforts to achieve substantial increases can be frustrated by bottlenecks that emerge when they accelerate one part of the production chain only to find that problems then …
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 excessive wear of chute liners. This leads to high maintenance costs and ...
