Hapman Conveyors
Conveying tests

Hapman Conveyors tests the conveying ability of customers’ products in one of its test laboratories at no charge using up to four conveying methods: flexible screw, pneumatic, tubular drag, or feeders. These tests demonstrate the effectiveness of the chosen system for handling your products. In addition, our tests provide valuable insight into whether customers need optional equipment, such as flow aids or engineered adjustments to enable optimal processing rates. Analysis of material segregation or degradation, along with bulk bag unloading trials, can also be provided. Kalamazoo, MI, 269-343-1675, www.hapman.com

Processing-applications testing of dry, free-flowing commodities The company maintains a complete, up-to-date testing laboratory for processing applications on all types of dry, free-flowing commodities. Sample products can be evaluated based on particle size or weight. Flow-line recommendations can be made based on the results from the evaluation. Laboratory-sized and full-size equipment is available. Samples as small as 1 lb. or as large as several hundred pounds can be worked with. The testing lab is also used as a training site. With appropriate samples, the company can provide operator training for production machines. Full-scale flows can be simulated and processed in a continuous-flow condition. Common operator errors can be simulated in a classroom atmosphere. Solutions can be demonstrated and applied to the real-life application. Lab work and training sessions are available at no charge. Companies can call Oliver if they have a separation requirement for their products. Rocky Ford, CO, 719-254-7813, www.olivermfgco.com
