·Ghaisas et al 4 developed a six Degrees of Freedom DOF model to study cage instabilities in roller bearings considering the roller race and roller cage pocket clearances for light load and high
·1 Introduction Impact crushers have become particularly useful in manufactured aggregates production because of the nature of the breakage mechanisms which allow direct fragmentation of the particles without leaving residual stress in them Wills and Finch 2016 As such material produced in a particular size range which may be controlled by the combination
·Measurements carried out show that the effective vibration velocity values detected at the points where the impact roller axis fits into the fixed roller table holder are higher than when using
The Equal Trough impact idler a conventional type carrier roller set consists of three equal length impact idlers supporting three rollers in one frame that is fixed to the conveyor structure In quarry and mining applications when large heavy and sharp materials fall on the conveyor they can impact and damage the belt ultimately leading
2 ·Rolling dynamic compaction RDC is a specific type of dynamic compaction which involves towing a heavy non circular module at a relatively constant speed This paper investigates the effects of module mass operating speed and varying ground conditions on the effectiveness of the 4 sided impact roller using a developed finite element…
The Cofra Roller Compaction CRC method also referred to as High Energy Impact Compaction HEIC is a technique that densifies loose granular materials up to a depth of 2 to 3 meters below the surface by pulling a non circular roller over the surface of an area How it works

·Over the past few decades several researchers have attempted to model roller compaction process Johanson 1965 Katashinskii 1986 Dec 1991 Bindhumadhavan et al 2005 Reynolds et al 2010 Odagi et al 2001 Johanson 1965 developed a model to predict pressure profile in a powder passing through counter rotating rolls under pressure as a function
·In all these models the impact between the pin/bushing and bushing/roller pairs was not considered In addition the force model used to describe the contact between the roller/sprocket pair generally used for the chain meshing dynamics represents the internal contact between cylindrical geometries that does not relate to the geometry of the
·Summary Impact rollers have found increasing application over the last 20 years In the area of bulk earthworks however their use has been limited and impact rolling is not referred to in AS 3798 1996 Although impact rolling works in a similar manner to conventional dynamic compaction it is rarely referenced in guideline
·High energy impact rollers IR have been increasingly used for earthworks by compacting on site soils The IR applies high energy to the ground and densifies deeper soils than conventional rollers and plate type compactors A trial program was implemented on the third runway of the Shanghai Pudong International Airport in China to validate the
