If you have a rotary biomass dryer, chances are you have dealt with the three most common problems in biomass rotary dryer systems: rocks, fires and explosions, and nonuniform moisture content in final product. Get advice on dealing with all three.

For years now, specialized sands known as frac sands have been utilized to augment the production of natural gas and oil from wells.

Hydraulic fracturing, or fracking, is a mining technique that greatly enhances oil- and gas-well productivity and is being aggressively deployed all over the world and particularly in North America.

A number of plausible mechanisms can explain kiln and dryer vibrations. The company explains eight common reasons and offers recommendations in a white paper on its website.

As is true with most mechanical equipment, not all dryers and kilns are created equal. Perhaps even more dramatic is how the design of flighting systems — the fins or baffles installed inside dryer drums to direct airflow and product within the dryer and optimize drying — have changed over time.
