bulk solids handling Journal Technical Article Sampling and Dividing of Bulk Materials The quality control of a product during initial, intermediate and final stages of production is best achieved with accurate sampling and sample division. It is of great importance that the sample taken is representative of the whole. The result of the quality determination of the sample is often the…read more
Case Study ContiTech: 24/7 Smart Service for the Toughest Mining Conditions ContiTech is taking an unusual service approach in the world’s largest underground iron ore mine in Kiruna, Sweden. Kiruna is situated north of the Arctic Circle and is roughly a 15-hour train ride away from Stockholm. It is Sweden’s northernmost town and arose as a settlement for the mine of th…read more
bulk solids handling Journal White Paper The Hogan Vibratory Bin Discharger The discharge of powders stored in bulk has always been a problem, and there are many devices schemes and designs to ensure that material once in a silo will flow out again. The subsequent control of that flowing material is considered a separate problem. This paper discusses the mechanical make-up …read more

bulk solids handling Journal White Paper The Design and Operation of Bin Activators The Bin Activator was developed almost 20 years ago in response to the basic processing need for reliable material flow from storage. At the time of its conception volumetric vibrator feeders which could meter a variety of materials with accuracies of ± 1 to 2%, were gaining greater acceptance thro…read more
bulk solids handling Journal Research Paper Stochastic Models for Gravity Flow: Numerical Considerations aterial flow analysis is commonly required in mining methods were the rock has to move from its initial position to the extraction point, commonly known as gravity flow. This happens in mining methods such as sublevel caving, panel caving, block caving. During this process the ore is diluted with wa…read more

bulk solids handling Journal Case Study Clean and long-lasting Conveyors – Slider Cradles designed to reduce Conveyor Spillage and Belt Wear Belt loading and material transfer point, resp., are prone to increased spillage and wear, due to the impact of the falling material and its settling. Newly developed slider cradles minimise these undesirable effects. read more
bulk solids handling Journal Case Study Design of a High Speed Transfer Chute in a confined Space – A DEM Case Study This paper aims to redesign a transfer chute as used in a Eurosilo system specifically for handling coal. The velocity of material vertically entering the chute was estimated at 15 to 34 m/s depending on the fill height of the silo. A three-stage approach was taken. First the existing situation with…read more
