portion, 500g, on a fixed bed at 950 to impact forces. Essentially, the requirement is that the ore must withstand impact forces as it descends down in the furnace. The reason is that small particles could clog the furnace bed and thereby block the rising reducing gas. The shatter test determines the ore’s susceptibility to breakdown due to impact during loading, unloading and charging

Impact Load Factors for Static Analysis Often a designer has a mass, with a known velocity, hitting an object and thereby causing a suddenly applied impact load. Rather than conduct a dynamic analysis an amplified static analysis is used, at least for the preliminary design. In a static stress analysis the static force (or weight of the mass) must be increased by an “Impact Factor” so as

The burden materials, which are charged through the throat, are coke, lump ores, and agglomerated ores in the form of sinter or pellets. Lump ores are significantly cheaper than pellets and sinters. However, they are inferior, particularly with respect to softening-melting and they affect the smooth running of the blast furnace and increase the coke consumption

Raindrop impact alone can result in large amounts of soil being moved. However water or wind moving over the surface will remove more soil, and contribute to sheet, rill and gully erosion. However water or wind moving over the surface will remove more soil, and contribute to sheet, rill and gully erosion.
This is done by passing low-pressure air through an overlapping configuration of porous membrane media and into the bed of the material being handled. Heavy lumps fall and are caught in the bottom of the lump trap which automatically empties using a level sensor and a series of slide gate valves.
ADVICE SHEET. Clay lump is a form of earth construction used in the District from the mid 18th Century until the early 20th Century. Clay lump differs from other forms of earth construction in that the material is formed as blocks, in wooden moulds rather than being built as one solid mass, as is cob, pise de terre and adobe, and can therefore be defined as a form of masonry construction.

The material properties of coal and air are measured and listed in Table 3, where φ is the sphericity of lump coal particle, which is defined as the ratio of the surface area of a sphere with the same volume as the given particle to the surface area of the particle. We calculate the sphericity on the basis of a three dimension scanning model of the lump coal particle, which was placed on a


Chutes are designed for the worst possible conditions and material characteristics. It is essential to derive by testing the material characteristics such as size distribution, maximum lump size, moisture content, angle of repose etc. For changing conditions, the spectrum of characteristics is required.
Since material size, weight and the drop height can cause considerable impact force that can damage the belt, the right impact bed must be chosen to absorb the impact energy and minimize any damage to …

and the process material. Unlike reflection-based technologies, the beam fully penetrates the bed, so there is no impact from vertical segregation. The Monitor uses a combined Group Delay and attenuation technology to determine moisture content. The technology operates on both fabric and steel cord belts. Measurements are independent of lump size and belt speed. The TBM Series automatically
A stream of falling material hits the plate of an impact weigher and the horizontal force sensor allows the mass flow rate to be calculated from this.
