A steel plant was having trouble with iron ore sticking to the walls of the hopper. The wet and slightly sticky material would accumulate in the hopper creating a blockage. Production couldn't run smoothly and the plant had to hire people to continuously knock material off the wall of hopper to keep the flow of material running smoothly.
Details· Iron ore cars, better known as simply ore jennies, are a specialized type of hopper car designed exclusively to haul heavy loads of iron ore.

The horizontal stiffeners are the main stiffners to the bin and have varying spans. The shell is protected with internal liner plates and impact rails.
Details· the design of light gauge hopper structures is rare. The term "light gauge" is used here to describe the class of cold-formed silo structure which is not restricted by a nominal minimum plate thickness requirement (eg 1/4" or 6 mm).

Details· Everett [2,3] discusses methods of iron ore quality control. Kamperman et al [4] describe application of these methods to a West Australian iron ore mining operation. 2 Scope This paper describes a computer-based simulation model to aid the design of a stockpile system, based upon real data, to give improved quality control while
Details· Silo and Hopper Design for Strength. Silos and hoppers are widely used in a great many different industries for storing a huge range of different solids. The sizes of these silos may vary from capacities less that 1 tonne to the largest containing as much as 100 000 tonnes. The size of the silo has a strong bearing on the number of different ...
Details· The hopper outlet length along tray will be of specific (small) dimension, not like long opening (free dimension) in case of belt feeders / apron feeders. The equipment should be used with caution for wet or iron ore application (if electrical protections are not up to the mark). The typical capacity range is up to 600 m3/hour.
Details· Simpler design and equipment than conventional large BF. It has flexibility with ore burdening with ore burdens can vary from 100 % iron ore lumps to any blend of iron ore lumps and agglomerates (sinter or pellets) in the …

Details· Studies are described of in-bin segregation, flow pattern and discharge segregation of ternary mixtures of ore and coke (−8 +6.15; −5 +4 and −2 +1 mm) in a model Paul Wurth hopper. Measuring techniques used include heap freezing, tracer addition, contour mapping and screen analyses. The results show that on filling the hopper small ...
Details· δ. φ. Jenike [1] found that the hopper angle required to allow flow along the walls depends on the friction between the powder and the walls, the friction between powder particles, and the geometry of the hopper.Design charts originally developed by Jenike [1] provide allowable hopper angles for mass flow, given values of the wall friction angle and the effective angle of …

Details· mixture of copper ore, charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag, which was tapped off.

DetailsThe 21ton steel-bodied coal hopper was based on an LNER design and was the standard BR coal hopper until the advent of air-braked types in the 1960s and 1970s. Over 23,000 wagons were built, making them one of the most numerous types on BR and, although seen in many places, they were most at home in the coalfields of North East England.
Details· Advantages of this feeder design: Large vibrating opening, up to 12′ x 12′, permits large hopper discharge openings for greater drawdown volume. Compact, low profile design reduces tunnel depth for substantial savings in …
