CDM Screw Conveyors are a simple, effective and versatile conveying solution for a variety of commodities and applications.  Screw conveyors have been in operation since the days of ancient Greece. They remain a common equipment selection for thousands of industrial and manufacturing applications that require an efficient, cost-effective way to move a variety of bulk materials from one process to another. […]

In any manufacturing or production operation, one of the biggest variables in calculating reliable profit projections is the constant reality of downtime and the related financial costs. While the exact number depends on the specific business and industry, an International Society of Automation study estimates that downtime costs the manufacturing industry nearly $650 billion each year. Ignoring the financial cost of […]

Without a guaranteed one-size-fits-all solution available, many screw conveyors need custom alterations to maximize efficiency and ROI. By Andrew Parker, President, CDM Systems, Inc. Introduction The screw conveyor is the oldest type of conveyor in recorded history, utilizing the oldest mechanical device employed by mankind: an inclined plane with a helix wrapped around the core1. Archimedes’ design for the first […]

Every industry faces challenges. For the global fertilizer industry, expansion and demand are not on the list of business concerns. Some analysts estimate a 14% annual growth rate, which would translate to an expected annual market value of $1.88 billion by 2020. This is partially due to the excessive use (and misuse) of chemical fertilizers over the past several decades […]

The global fertilizer industry is experiencing unprecedented growth and demand. As the world population rises and is expected to reach 9 billion by 2040, a constant, increasing demand will be placed on fertilizer in an effort to boost crop yields without the expansion of harvestable acreage. In addition, after decades of excessive chemical fertilizer use (and misuse) that contaminated the […]

“What goes up must come down” is a quote (attributed to Isaac Newton) and a concept (the law of gravity) that most people are familiar with. When applied to conveying material, the second part should be adjusted to: “What goes up probably needs a bucket elevator.” One of the many types of bulk material handling equipment offered by CDM Systems, […]

CDM conveyors provide rugged, reliable service. Also contributing to maximum uptime is easy field maintenance. As this animation illustrates, the tail shaft assembly on CDM conveyors features a segmental tail sprocket / idler design that allows segment replacement on the sprocket / idler without the removal of the tail shaft.

At some point, everyone learns that the shortest distance between two points is a straight line. The ancient Greek mathematician Archimedes is credited with first articulating this concept, which has since become not only an accepted geometric fact when applied to flat surfaces or planes, but a general rule of life. However, his statement doesn’t necessarily hold true in every […]
