Engineering properties of pearl millet varieties (Pusa composite 443, Pusa 701, Pusa1201 and Pusa1801) were evaluated at varying moisture content (10-25% wb). A significant varietal difference was found on studied properties. GMD, Surface area, thousand grain mass, the angle repose, porosity, internal coefficient friction, static friction (Poly, GI, MS Al) increased linearly with increase in wi...

Bulk solids commonly segregate when particles move on an inclined surface, often causing significant variations in content uniformity of particle properties such as size and species. Often called free surface rolling segregation, this is one the most common segregation phenomena for powders granules, where different sized shaped become separated due to differential movement surface. Intensity w...

The flow properties of powdery or granular filling substances for dangerous goods packagings are safety-relevant parameters. To specify the behaviour, angle repose is measured in recognized test centres Germany. Previous investigations performed on non-hazardous revealed that some methods currently used have disadvantages application. Additionally, occupational health and safety reasons, it was...

In order to reduce the power consumption of screw conveyor and improve productivity, this study investigated such mechanical characteristics rubbed maize straw as coefficient sliding friction, angle repose, internal friction coefficient, cohesion, flow function value compressible with respect its moisture content density. An experiment was designed consists a characteristic test-bed, direct she...

Starch is one of the food sources that can be extracted from cereals, roots, tubers and stem. Sago palm (metroxylon spp.) example starch source. The efficiency extraction process depends on mechanical properties material. This study was conducted to determine angle repose between grated sago kinetic friction contact surface material machine. (θ) determined by using a cone shape hopper attached ...

The height/radius ratio of a tumulus and the angle of repose for the materials used in its construction permits one to: predict possible construction methods, calculate the path of geometric evolution before and after the current form and compare degrees of preservation. By way of example a Neolithic tumulus is compared with a modern-day one, both made out of identical lithology. Finally, comme...

Senna leaf (Cassia acutifolia) is a plant that widely known by the public to treat constipation. products have weaknesses in form of an unpleasant aroma and taste use inappropriate doses. This study aims determine effect variations levels lactose mannitol as filler on physical properties effervescent granules senna extract. Effervescent were made using melting method with ratio 25% : 75%, 50% 5...

Introduction: In future human exploration of Mars, many challenges face us. Mars is a dusty planet and dust and windblown particulates will present one of the most significant difficulties [1]. The dust and granular regolith will challenge materials, machines, and people. Our experience with dust-covered astronauts on the Moon and with landers and rovers on Mars suggests that significant effort...
