bulk solids handling Journal Case Study Floating Pneumatic Unloaders The unloading of bulk dry solids from ships is possible in a number of ways. Where fixed dock installations are contraindicated for one of several reasons a realistic solution is the use of floating unloaders, which can be moved from dock to dock and even port to port. This article describes a syste…read more
bulk solids handling Journal Research Paper Load Analysis of Trestle Leg Conveyor Support Structures Buried in Stockpiles The paper presents a theory, combined with design equations, to compute the loads on structural elements, in particular those of trestle legs of tubular construction supporting load-out belt conveyors, where the trestle legs are substantially buried in gravity reclaim stockpiles. The stress conditio…read more
bulk solids handling Journal White Paper System for Coal Car Unloading at Rail to Water Terminals The past and present decades have seen a rapid growth in the export of coal to foreign countries. Normally, coal is brought to the export terminal by trains made up of either unit train cars (cars of same size and capacity) or of random cars (cars of varying sizes and capacities). If the rolling sto…read more
