This case study investigates the factors behind the ignition of a combustible dust cloud during a manual powder processing operation. In this example a process operator was tasked with manually tipping approximately 18 kg (40 lbs) of powder from a plastic drum, constructed from polyethylene, into a metal process vessel. The plastic drum contained a combustible powder that had a minimum ignition energy of 12 milli-joules. A metal chime was positioned around the circumference of the top of the plastic drum to provide it with impact protection from daily usage in the plant.

Neponset (IL), United States – Since most Conveyor Injuries occur during Routine Maintenance or Cleaning, the Control of fugitive Materials is one of the most important Factors to reduce Hazards and prevent Injuries. In this article Martin Engineering explains how, in a properly-engineered transfer point, each component is employed to maximize its specific function and contain dust and fines, while at the same time offering workers easy access for maintenance. Continue reading Conveyor Transfer Point Design: Material Containment for Safety & Efficiency
Löhne, Germany – With its ZS 92 S series, the steute business unit “Extreme” is presenting a new series of emergency pull-wire switches especially designed for Extreme environments. The die cast aluminium housing, for example, is very robust and multi-coated (passivation, base coat, powder coating). Continue reading steute: Emergency pull-wire Switch for extreme Environments
Braeside (VIC), Australia – Since 2015, Kinder Australia has acquired the exclusive Australian distribution of K-AllShelter®/Capotex Conveyor Belt Covers. K-AllShelter/Capotex belt covers deliver robust, aerodynamic and lightweight solution that ensures personal safety from moving parts, suppressing dust and protects the environment. These are now issues that address growing environmental compliance requirements for Australian bulk materials handling operations. Continue reading Kinder Australia: Conveyor Covers – Protecting People and the Environment
Drachten, Netherlands – For a great many reasons, the conveyor belts used to convey coal or other bulk materials are highly unlikely to be suitable for carrying biomass. Sadly some very expensive lessons are already being learnt. Here Les Williams of Dunlop Conveyor Belting discusses the essential and very specific characteristics that biomass-carrying belts must have in order to perform safely and efficiently. Continue reading Dunlop Conveyor Belting: Conveying Biomass – the Safety and critical Importance of Conveyor Belt Technology
Neponset (IL), United States – The ability to maintain the proper force required to keep the edge of a belt cleaner blade against the belt is a key factor in the performance of any cleaning system. Blade-to-belt pressure must be controlled to achieve optimal cleaning with a minimal rate of blade wear. A belt cleaner that is properly installed and adjusted as described in this Martin Engineering article helps to minimize carryback and spillage, reducing risk and overall operating costs. Continue reading Martin Engineering: How to achieve cleaner, safer and more productive Conveying with optimized Belt Cleaner Tension
Neponset (IL), United States – The Coffeyville Resources Nitrogen Fertilizer plant in Kansas has adopted innovative belt cleaning, alignment and modular chute technology to resolve tracking, spillage and dust problems on two conveyors transporting petroleum coke (petcoke). Martin Engineering redesigned the system with belt stabilization and chute sealing technology, sensitive belt tracking equipment and heavy-duty primary and secondary belt cleaners.
Braeside (VIC), Australia – WARNING! Enter with Extreme Caution! On-site safety signs are designed to alert maintenance workers to potential hazards before entering and performing maintenance work in dangerous and unsafe materials handling environments such as inside chutes, silos and hoppers. Often the necessary maintenance work may require permits and adherence to safety precautions before entering these “confined areas”.
Mansfield, UK – Martin Engineering has expanded its UK and Scandinavian operations, allowing it to offer wider service, faster equipment delivery and extensive employee training to customers. Martin Engineering’s new facility located near Mansfield, Nottinghamshire includes a new office, training centre, production area and warehouse.
Sterling (IL), United States – Sterling Systems & Controls, Inc. announced that its Micro/Minor Ingredient Batching Systems can be provided with custom features that enhance personnel health and safety, along with added increases in productivity. Ingredient batching systems are multi-bin modular batching systems. As batches are made, the ingredients are emptied from the bins. Eventually the bins need to be refilled.
