This paper discusses how many of the common practices in conveyor specification and design are out of date compared to the current expectations of users for safe, serviceable, reliable, and fugitive material-free conveyance of bulk solids. Ten of the most common mistakes made in the specification and design stages related to user expectations are reviewed along with the cost vs. price implications of those decisions. A general specification and design hierarchy that designers can use to improve conveyor design is included. Source

It sometimes occurs that the conveying of bulk solid materials via belt conveyor poses a significant problem due to the conveyed material's characteristics. The following article presents one such case, and the solutions found to solve the problem. Source

An American cement producer faced severe problems of material builup in his preheater. Manual hydro-lancing meant process disruptions. So they approached Martin Engineering for a more sophisticated solution. © Vogel Verlag und Druck GmbH and Co. Kg. All rights reserved. Source

Stark Excavating, a Ready-Mix Concrete plant in the Midwestern United States has resolved material build-up issues in three storage silos where accumulation had slowed production and increased internal pressures, eventually damaging the vessel walls and forcing a shutdown. The company contacted Martin Engineering, which provided a heavy duty whip. The Martin heavy duty whip is a portable, remote-controlled tool that can be lowered into storage containers through a manhole opening. Powered by compressed air, the patented motor can use a variety of different flails and cutting edges to knock down accumulated material without damaging storage vessels. Martin's top-access cleaning technology eliminates the need to send a man inside a storage vessel and risk potential injury. The equipment is set up outside the silo, and it's portable enough to maneuver around various bin sizes and shapes. The silo restoration will include removing all internal horizontal supports, pulling all sidewalls back to their origin. Source

Fugitive material has been an issue in bulk material handling for as long as conveyors have been in use. Dust and spillage create a variety of potential hazards and waste valuable resources. Consequences of regulatory violations can range from simple warnings to massive fines. A proactive approach is to eliminate the root cause, typically through the use of dust collectors to gather and filter dust-laden air. An alternative to the common central dust collector is the integrated air cleaner, which eliminates the need for large, complex air handling systems in favor of smaller, independently operating units at the dust generation points. Specifying an air cleaning system requires quantifying cost and power usage to develop a systematic evaluation of the options. In many cases, the integrated approach is superior to central designs, with lower capital investment and reduced cost of ownership. Source
