Cargo angle of repose The maximum slope angle to horizontal at which material will not slide Certain cargoes can be carried with an angle of repose (in a pile). Nickel ore cannot sustain an angle of repose and is trimmed flat. If you carry the cargo with an angle of repose, there is a risk of sheering.
A number of recent bulk carrier losses have been attributed to the liquefaction of different ore cargoes, especially nickel ore. The mandatory application of the International Maritime Solid Bulk Cargoes (IMSBC) Code enhances the safety of bulk carriers through the setting of constructional and operative requirements.

We have developed a DEM model to study the packing characteristics of iron ore granules. Two important indices in characterising the packing of granules, i.e. the angle of repose (for packing stability) and a size segregation index, were obtained from the simulations.The comparisons of the simulated and experimental angle of repose and size segregation indices showed good

Apr 08, 2018 This drawdown angle varies from material to material but is usually about ten degrees steeper than the angle of repose for the material. In other words, if the angle of repose is 38 degrees, the drawdown angle is usually about 48 degrees. Obviously, the drawdown angle will vary depending upon the size range of the material and its wetness.
The granular material will assume a certain angle as it flows within the rotating cylinder. This method is recommended for obtaining the dynamic angle of repose, and may vary from the static angle of repose measured by other methods. When describing the angle of repose for a substance, always specify the method used.
Feb 14, 2012 The angle of repose is the angle on the sides of a substance, like sand, when it is poured out and forms a heap. The angle of repose of desert sand is the same as the angle of the sides of a pyramid.

The physicochemical properties of nickel laterite ore powder were investigated by XRD, SEM and TG/DSC characterization techniques. The mechanical properties including repose angle and friction angle were measured by powder performance tester and direct shear apparatus. The result of XRD showed that the main phases of nickel laterite ore powder were lizardite and

The angle of repose () is calculated from the equation arc cosD/(l 1 l 2). The relationship between flow properties and angle of repose has been established. When the angle of repose is less than 25 degrees, the flow is said to be excellent on the other hand, if the angle of repose is more than 40 degrees, the flow is considered to be poor.
The angle of repose of a material is the acute angle which the surface of a normal, freely formed pile makes to the horizontal. The angle of surcharge of a material is the angle to the horizontal which the surface of the material assumes while the material is at rest on a moving conveyor belt.This angle usually is 5 degrees to 15 degrees less than the angle of repose, though in

Jul 15, 2017 Nickel ore liquefaction has a direct correlation between the parameters of moisture content (MC) within the cargo and the response motion of the ship steering through its encountering weather condition at seas. The focus parameter of the potential onset of liquefaction is the amount of moisture content within the cargo. ... Angle of repose ...

Several bulk cargo ships transporting fine and moist iron or nickel ore have capsized after becoming unstable from product shift. The cause of the loss of cargo stability has its roots in the ability of certain bulk solids, which seem to be solid or stable before leaving port, to liquefy under external excitation, such as vibration or motion.
