Bulk Solids Quarterly – July 2014

CEO Message

We are continuing to expand our team of solids handling specialists and the range of services to meet our clients’ needs. As you will read below, we recently broke ground for the expansion of our headquarters, and construction is well underway. We are actively adding to our talented team around the world. More and more of our projects range from characterization of the bulk solids handled to functional design of systems and equipment, to detailed designs of the chutes, silos, and other handling equipment. Our clients benefit from single-source supply of these services, as well as the assurance that critical design information flows seamlessly between the different stages of a project.

Alumina Powder Silo Retrofit Improves Product Quality

Alumina is a fine powder that is used in the manufacture of aluminum, abrasives, refractory material, and various household products. The quality and consistency of the alumina, which can vary within each railcar, can affect the manufacturing process. Some processes can detect and compensate for gradual changes without any significant loss of product quality. However, rapid changes may result in a significant loss of finished product because of unacceptable variations.

Eccentric Discharge from Silos – by Jesús Chávez Sagarnaga

Silos are one of the most critical pieces of equipment in industrial facilities and, at the same time, one of the least understood. When designing a process in an industrial plant, it is assumed that all bulk materials will be handled reliably. However, as these processes increase in complexity and size due to plant improvements and greater global demand for products, many storage silos are designed or modified to discharge eccentrically.

Chemical Engineering Progress – Ten Steps to an Effective Bin Design

The design process for silos, bins, and hoppers is often thought of as a “black art,” known by only a chosen few. However, a proven, practical method for storage bin process design has been in use for over 60 years. Just as a pump must be designed specifically for the liquid it will handle, so, too, must a silo be designed for a particular powder or bulk solid. The characteristics of the material being handled will dictate the storage vessel design.
