Torque overloads can cause serious problems for rotating machinery, but an understanding of torque limiting technologies can help engineers to enable more reliable operations Reliability, safety and productivity are key terms that come to mind when considering manufacturing plant operations,…
A clear understanding of grout material properties is important to ensure that equipment is effectively protected against vibration and misalignment Reliability of critical rotating equipment depends first and foremost on maintaining precision alignment. This requires a robust foundation under the…
This column is based on “Propylene Oxide from Propylene and Chlorine – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/propylene-oxide-e11a. Propylene oxide (PO) is a highly reactive commodity compound that serves as a starting material…
The activated sludge process (ASP) is designed to speed up the rate of decomposition of waste material in water. First developed in 1914, it remains an important means of treating both municipal and industrial wastewaters. This one-page reference provides information…
The new two-stage Sogevac NEO D rotary vane pump (photo) is equipped with a high-quality exhaust filter inside the oil casing. Built-in filtration reduces the required integration volume of the pump and ensures a cleaner environment without oil smoke or…
The new Allen-Bradley Micro 870 programmable logic controller (PLC; photo) can support applications that require up to 304 I/O points, 280 kB of memory and 20,000 program instructions. The Micro870 PLC uses a flexible design concept that provides designers up…
The E-finity (photo) is a continuous, dense-phase conveying system for fragile materials. Precise pressure monitoring and airflow corrections allow the system to operate efficiently under a wide range of conditions, while gently inducing materials through the conveying line in slug…
The CGM 750 (photo) is a new cone mill with a diameter of 29.5 in. (750 mm) that gently grinds fatty, heat-sensitive, sticky, moist or fragile materials into uniform particle sizes with minimal fines at rates up to 32 metric…
The CL 10HY-V2 density cell and Series 2000 density digital converter (photo, p. 37) can be used to measure the density of ammonium hydroxide, caustic soda, ethylene glycol, methanol, nitric acid, oleum, phosphoric acid, sodium chloride and sodium hydroxide. The…
The Rosemount CX1100 in-situ oxygen analyzer (photo) is said to be the first high-performance, zirconia-cell-based combustion-control system designed to improve energy efficiency and meet environmental regulatory requirements for small and midsize boilers. It features the same sensor reliability found in…
