(Photo by Justin Edmonds/Getty Images)The world of sports broadcasting lost one of its true legends today following the passing of longtime Colorado sports personality Irv Brown at the age of 83.As iconic face in the city of Denver and the state of Colorado, Brown served as an NCAA basketball referee, a coach in baseball, basketball, and football, as well as a radio personality for over 40 years.Working alongside Joe Williams, Brown co-hosted the popular “The Irv and Joe Show” on Mile High Sports Radio for 25 years until his retirement in 2016.Per FOX Denver, Brown coached three sports at Arveda High School, baseball at the University of Colorado, and baseball at Metropolitan State University of Denver.We lost a Colorado icon today. Irv Brown – coach, ref, radio/TV raconteur. He worked for ESPN before it became the world leader. He practically invented sports talk radio here in Denver. He knew EVERYBODY. He helped EVERYBODY.We are forever indebted my friend. pic.twitter.com/MMSLhnnVrR— Vic Lombardi (@VicLombardi) February 3, 2019Brown also served as a basketball analyst for ESPN.Per Benjamin Albright, he was also the color commentator for ESPN’s first-ever college football broadcast, pitting Oregon against Colorado.Irv Brown, he was a legend.Pioneered sport talk radio in the 70’s, coached baseball at Colorado, refereed six NCAA Final Fours, was the color guy for the first broadcast of college football on ESPN (Oregon/Colorado), an NBA analyst for ESPN & a baseball exec.RIP pic.twitter.com/JdDjRpiIZE— Benjamin Allbright (@AllbrightNFL) February 3, 2019Among Brown’s accomplishments as a referee are the six Final Fours that he officiated, as well as five NCAA championship games.He oversaw three of John Wooden’s NCAA title wins with UCLA, and the 1976 title game between Indiana and Michigan, where the Hoosiers won 86-68, capping off a 32-0 season that remains the last undefeated NCAA title winner.In 1997, Brown was inducted into the Colorado Sports Hall of Fame.last_img read more

Field trial confirms Metso MHC Series industryleading hydrocyclone performance

first_imgBased on extensive market research and industry feedback, the Metso MHC Series Hydrocyclone was developed focusing on delivering improved process performance and maintainability. To make sure the designed features meet the targeted results in production, Metso launched an extensive validation process covering various hydrocyclone sizes and applications in both pilot and field trials. The laboratory testing was performed in the Metso York Laboratory in Pennsylvania, US.  The targets for the initial testing were to evaluate efficiency, sharpness, fines bypass, and cut size for a homogenous ore type (limestone).The results from the laboratory test indicated very encouraging performance from the MHC internal geometry. At a reasonable operating pressure of 124 kPa, the cut size on a 250 mm hydrocyclone is below 30 microns. When operating in this condition, the cyclone efficiency is almost 90%. Efficiency is defined as the mass percentage of product size in the hydrocyclone feed that reported to the overflow (product size defined at the 80% passing point of the overflow).For the field trial, a Metso MHC650 (650 mm diameter) was installed in the grinding circuit at a copper concentrator in southwestern US. The goal of testing a production unit in a large-scale copper mine was primarily for wear component prototyping and continued process data collection.Various grades of rubber and polyurethane have been tested within the different hydrocyclone components. Ceramic inserts into polyurethane was first introduced as an apex insert, and secondly at the bottom of the conical section. The ceramic components are still in operation and are the focus of current wear component development and prototyping.To date, that field trial has been in operation for over 12,000 h. The data generated from the trial is being applied to Metso’s empirical hydrocyclone model used for sizing and simulation purposes. “It has confirmed the MHC Series achieves the performance for industry leading hydrocyclone technology. The field trial also confirmed that the MHC performance is predictable and responds as expected due to changes in operating conditions. Testing in the field and on the pilot scale is an ongoing process as the Metso MHC product line continues to develop.”“Based on the test program, the MHC Series performance is proving to be industry leading with an increased flow rate for a given pressure drop. Wear components within the individual units are optimised to promote even wear life throughout the entire assembly, resulting in increased overall wear life and consistent performance throughout the hydrocyclone lifecycle. These advancements have great potential to deliver long term benefits in improving classification efficiency while considering capital costs and operating costs.”last_img read more
