By N. Barlmeyer – Pneumatic conveying of punched metal parts using negative pressure is a real challenge. Johnson Controls is generally using negative pressure systems for conveying of punch waste in the production of lead-grids for starter batteries for automobiles. For a new production line of battery-grids the company selected a positive displacement blower.

By N. Barlmeyer – Compressed air is often essential for transport, loosening and/or homogenisation tasks in producing powdery goods. This also applies to cement plants, where large numbers of screw compressors and positive displacement blowers are used in the production process.

By M. Bradley, R. Farnish, T. Deng – There are many means of providing wear protection for bends and straight sections in pneumatic conveying systems, but they can be very costly or severely increase the energy consumption, or limit its throughput, if applied too liberally. Hence it is very important to choose carefully the right means of wear protection. Continue reading Predicting and Preventing Wear in Pipe Bends – Basic Information for choosing a cost-effective Wear Protection Solution
Bethlehem (PA), United States – At Montgomery County’s North Incinerator plant, there was a problem several years ago. The Dayton, OH, area trash-to-energy plant was experiencing repeated shutdowns due to sweep elbow failure in its dense phase pneumatic conveying system, a component of the lime injection system in operation there. Continue reading North Incinerator Finds Solution to Excessive Sweep Elbow Wear
Bethlehem (PA), United States – At Miller Brewing Company’s Fort Worth, TX, facility, staff engineer Roy Marin was faced with an interesting problem two years ago — a problem that was solved by using the patented HammerTek Smart Elbow® deflection elbow. The Smart Elbow flow device provides change of direction in pneumatic and slurry conveying systems without the wear, plugging, product degradation or contamination problems which characterize sweep elbow and plugged-tee equipped systems — and does so in far less space. Continue reading Smart Elbow® Deflection Elbow Installation Brought in $30,000 Under Projected Budget
Bethlehem (PA), United States – HammerTek® SMART ELBOW® Deflection Elbow prevents breakage and dusting of fragile materials such as pet food, coffee beans or grains by eliminating impact and frictional heat. Conventional impact elbows conveyed at high speed, degrade the material and generating fines caused when friable materials hit the outside radius which decrease product quality, consistency and salability while increasing waste.

San Antonio (TX), USA – Robert Ober & Associates is a specialty design/build firm that serves an international client base for bulk material handling projects that range from USD25,000 retrofit contracts to USD25 million turnkey plant projects. The company began specifying Smart Elbow® deflection elbows from HammerTek® Corp. in 2001 to reduce elbow wear and related downtime, but now also relies on them to cut offload times, reduce degradation/dust, improve safety and reduce the space needed for conventional sweep elbow installations.

Severna Park (MD), United States – Concrete Plants, Inc. (CPI) has provided turnkey batch plant equipment, service and parts to ready-mix and precast concrete plants from Maine to South Carolina since 1974. For many years, customers were resigned to abrasive materials wearing through the elbows of their pneumatic conveying system elbows until 2001, when CPI began specifying HammerTek deflection elbows, in which abrasive materials are prevented from impacting the elbow wall. Continue reading HammerTek: Ready-Mix Plants Prevent Wear and Downtime with Deflection Elbows
Somerset (NJ), United States – Process equipment manufacturer Gericke, USA, has unveiled the Pulse-Line™ PTA PL dense phase pneumatic conveying system. Featuring a patented design, the Pulse-Line PTA PL pneumatic conveying system automatically forms dry, bulk materials into separate, pulsed slugs for highly gentle transfer at low gas velocities then injects additional air or nitrogen at key points along the conveying pipeline. Continue reading Gericke USA unveils Dense Phase Pneumatic Conveying System that protects delicate Materials
By N. Behera, V.K. Agarwal, M.G. Jones, K.C. Williams – Pneumatic conveying of certain bulk materials is widely used in industries due to certain advantages over other modes of conveying. As compared to dilute phase, dense phase conveying is a preferred method of conveying due to its low power consumption, low erosive wear and low attrition of particles. Fly ash and alumina being high aeration capable due to their fine particle size tend to be conveyed in fluidised dense mode at low velocities. In this paper, details of pneumatic conveying tests are presented which are carried out using fly ash and alumina as conveying material at different solids loading ratios for dense mode as well as dilute mode of flow.
