Macawber Engineering participated in the 2025 IPBS Trade Show in Rosemont, IL, where we showcased our low velocity, dense phase pneumatic conveying technology. This video features a live demonstration from the show, highlighting our system conveying plastic pellets in a slug flow regime—a process designed for gentle and efficient material handling.

Our show system demonstrates the power and precision of Macawber's dense phase conveying method, where material is gently conveyed on itself without the use of air boosters, minimizing the possibility of degradation. This method is ideal for a variety of bulk materials including but not limited to: Sand, Vermiculite, Dolomite, Lime, Barite, Bond, Bentonite, and Plastic pellets (as shown)

Whether you are handling difficult, fragile or abrasive materials, Macawber Engineering delivers reliable, efficient solutions that reduce wear and preserve product quality.

Pneumatic conveying has been a viable method of conveying bulk materials for over a century in industries across the world. As new industrial technological advances have been developed and brought to markets, the principles of pneumatic conveying have also progressed. The renewable, green power initiative is proving clean energy resources can come from other methods outside traditional oil and gas. Macawber’s dense phase technology amplifies these new technologies with capabilities to deliver feed stock to these processes and handle the byproducts including bed media, spent carbon, and ash. These systems are designed to minimize energy consumption while ensuring safe and reliable handling of materials that are often challenging to convey.

This Macawber dense phase pneumatic conveying system, designed specifically for conveying milled silica, is an engineered solution that ensures the safe and efficient transportation of the fine, abrasive material through a fully enclosed pipeline. Unlike dilute phase, the material is transported gently at a higher pressure and lower velocity, reducing the impact abrasive materials can present to operations. The value is immediate in the areas of reduced wear and minimized dust generation, both of which are essential when handling materials such as milled silica. Macawber’s custom solution to this application includes a 12-cubic foot Denseveyor®, 8-inch inlet Dome Valve®, and 6-inch outlet Dome Valve® to transfer 10 tons of material an hour at a distance of 128 feet. https://www.youtube.com/watch?v=6EpdZqLT3nw
