Jenike & Johanson Inc

Engineering Support & Solutions for Powder & Bulk Solids Storage, Handling, and Processing Equipment Bulk solids handling problems are a major cause of costly downtime and maintenance for many facilities. Flow problems limit throughput, impact product quality, and create safety and health risks, as well as reduce equipment life, increase maintenance costs and cause premature equipment failure. Jenike & Johanson has developed proven ways to design handling equipment to promote smooth, unrestricted flow of bulk solids safely and reliably. J&J does not guess at material properties, we measure them. For nearly fifty years, we have focused on developing first principle theories on bulk solids flow and conveying behavior. Our engineer’s practical experience is also critical to project success. We combine test results and real world project experience, which yields the best solution in terms of reliability and cost-effectiveness. Every step of their work is centered on a bulk material’s handling characteristics, whether it involves testing, engineering, detailed design or equipment supply. This proven sound approach continually produces outstanding results for our customers.

Engineering Solutions for Powder & Bulk Solids Handling Established in 1966, Jenike & Johanson is a world leading technology company for bulk solids handling, processing and storage. Key services include: · Investigation and root cause anlysis of material handling problems · System design and retrofit engineering to avoid or solve problems · Bulk material flow testing & process modeling · Custom process and flow test equipment · Training on solids flow and pneumatic transport Problems solved in existing facilities and avoided in new facilities include: · No flow or erratic flow due to arching and ratholing, in feed bins, weigh hoppers, and storage silos as well as chute pluggages due to cohesive solids (e.g., wet or sticky bulk solids) · Limited flow, flooding, and dusting of fine powders (e.g., cement, ash, fine minerals) · Segregation of mixtures (e.g., fines concentrating during handling steps) · Premature wear of material contact surfaces (bin and hopper walls) · Solids handling equipment failure investigations Jenike & Johanson has the largest and most complete laboratory in the world for characterizing the flow properties of bulk solids under representative environmental conditions. Skilled engineers provide detailed structural and mechanical design of solids handling equipment, and routinely design stockpile and gravity reclaim systems, silos, feeders, loading and transfer chutes, blending systems, and custom equipment (e.g., purge/drying/conditioning vessels, large slide gates, etc.).
