    Powder & Bulk Solids Belt Conveyor Injury Hazards Report

    Belt conveyors, like all types of equipment, pose some inherent risks to worker safety, as the systems contain a variety of areas and features that could potentially cause injuries. In an attempt to assess the challenges operators of belt conveyors face regularly, Powder & Bulk Solids compiled a report providing an overview on common belt conveyor injury hazards.  Analyzing data from the Bureau of Labor Statistics (BLS) from 2011 to 2015, PBS found that the majority of the 6080 nonfatal belt conveyor-related injuries occurred in manufacturing or trade, transportation, or utilities settings. While hands were found to be the most common body part impacted in belt conveyor injuries, other areas of the body are at risk, the data indicates. An average of 660 hand injuries occurred each year during the sample period. Is your operation prepared to tackle the risks associated with belt conveyors? Download Powder & Bulk Solids' full report to see the common risks the equipment poses to workers and some suggested steps to mitigate them.

    The State and Future of the Powder Handling Industry

    With decades of experience working to solve powder handling problems, founder of consulting firm Solids Handling Technologies Joseph Marinelli has observed the industry transform over the years. Despite milestones reached since the 1970s, Marinelli believes that our understanding of powder handling and practices around it have a lot of room to improve. In this piece examining the current state and future of powder handling, the consultant explains the history of developments in solids handling from the 1700s to now and outlines the challenges facing the industry moving forward. To learn more about where the industry is going in the next five years and the most important points for professionals to take into consideration moving forward, click below to register to access this free PBS whitepaper.

  • Hapman Systems Designed to Handle the Job Vacuum Conveyor System

    Major/Minor Dry Material Vacuum Batching System Systems Designed to Handle the Job Vacuum Conveyor System Major Ingredient Handling:  Bulk Bag Unloaders - Each is equipped with a 2 ton electric hoist and pneumatic bag agitation for efficient material   flow. The unloaders have load cells for the accurate, real-time measurement of material flowing out of the FIBC’s   (loss-in-weight). Each bulk bag unloader also contains a bag tie box for full-flow shut-off prior to full bag emptying. Gravimetric Screw Feeders – located at the discharge of each bulk bag unloader, the feeders meter the flow of material to  an accuracy of +/- 1%. Actuated diverting valves open to the percent required to meet the formula call for material.

  • Hapman APPLICATION REVIEW Food Processor

    Overcoming the Challenges of Handling Salt  in Bulk - The Moisture Absorbing Nature of Salt   Italian Food Processor Expands Pasta Line Purchasing in bulk bags or FIBC’s is a cost effective way for most process manufacturers to buy dry bulk materials. The cost of the material per pound is typically less when buying in bulk, storage of raw material requires less floor space, and the handling of bulk bags is more efficient by using fork lifts and bag unloading stations as opposed to operators manually dumping smaller bags into dump sta- tions or hoppers. Some materials can cause unexpected challenges when purchasing in bulk however. The molecu- lar construction of the dry material and its ability to attract moisture from the air and become compacted can create issues for processors. Salt is a compound mineral that can be hygroscopic in some forms resulting in caking and clumping (http://en.wikipedia.org/wiki/Salt).  

  • HAPMAN CASE STUDY Wastewater Treatment

    The Village of Gilberts, IL Achieves Wastewater Requirements with the  Help of Baxter & Woodman’s Innovative Pre-Treatment System Design   Harry Harman, P.E. of Baxter & Woodman, consulting  Engineers, received a call from an official with the  Village of Gilberts in the State of Illinois. The call was  a request for a review of documents from the EPA to  the Village regarding the 5 year renewal of the Village’s  National Pollution Discharge Elimination System (NPDES)  Permit. The Permit, is a set of standards developed by  the Environmental Protection Agency (EPA) for the  management of wastewater contaminant concentrations  allowed to be discharged into streams and rivers by  industry and public wastewater treatment facilities by  cities, villages, and townships. Upon review of the report,  Harry immediately noticed a more stringent limit on the  permissible levels of Barium. There were no treatment  systems available which would remove the Barium without  exceeding the recently enacted Radium limits established  by the Illinois Emergency Management Agency – Division  of Nuclear Safety.
