Fresh Air for Cement Plants – Loosen, Mix and Transport Powdery Goods with Compressed Air

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.

Predicting and Preventing Wear in Pipe Bends – Basic Information for choosing a cost-effective Wear Protection Solution

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

North Incinerator Finds Solution to Excessive Sweep Elbow Wear

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

Smart Elbow® Deflection Elbow Installation Brought in $30,000 Under Projected Budget

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.

HammerTek® SMART ELBOW® Deflection Elbow Prevents Breakage

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.

Pneumatic Deflection Elbows cut Wear, Dust, Offload Time for Bulk Project Contractor

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.

HammerTek: Ready-Mix Plants Prevent Wear and Downtime with Deflection Elbows

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.

Gericke USA unveils Dense Phase Pneumatic Conveying System that protects delicate Materials

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.

Parameters affecting Power Consumption in Pneumatic Conveying of Fine Particles

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.

The Proper Flow Rate – Material Feed Rate Control for Pneumatic Conveying Systems

By D. Mills, V. Agarwal The material feeding device is particularly critical to the successful operation of any pneumatic conveying system. Many of the feeders available have no moving parts and it is not always obvious how material flow rate can be reliably achieved.
