At Electra Mining Africa 2010, Multotec is exhibiting an extensive suite of products. Engineers on the booth explain how advanced technologies have been applied to the specific requirements of each minerals processing application. There is likely to be considerable interest in the Multotec Max 1450 cyclone, the Multotec spiral and Multotec Wear Lining’s exhibit, all of which have already been attracting significant attention in the market.Said to be one of the most cost-effective solutions in DMS, the Max range of hydrocyclones, developed by Multotec, are a great advance in alumina-tiled cyclone engineering design. Designed using extensive field experience and using computational fluid dynamic analysis and 3D CAD, the Max range offers a number of major features. The ‘Max’ designation is derived from the maximum efficiency of separation and maximum wear life provided by these cyclones.The Max 1450 cyclone boasts a number of innovative design features, including the inlet head which reduces wear and turbulence, lengthening the life cycle of the inlet and increasing capacity. The scrolled evolute inlet also provides for a higher capacity compared with a traditional tangential inlet, while the smooth evolute entry into the inlet results in a more efficient separation process within the cyclone. The inlet head can also be custom designed to meet the specific capacity requirements of customers.The parallel throat spigot design eliminates the initial high wear rate and maintains the spigot size for longer, while the overflow design enables any leak to be noticed immediately, eliminating the potential for the loss of product or mate- rial to the overflow.The major advantages of this more specialised design include the easy removal of the lightweight vortex finder and the ease of inspection to determine internal wear within the cyclone.The design of the flanged joints eliminates the possibility of efficiency losses through inward steps. The wetted joints are sealed with epoxy, thereby avoiding the problem of gaskets protruding into the cyclone body. Separation is enhanced, producing less misplaced material. Finally, pre-engineered tiles are designed to ensure that lining failure is prevented while the wear life of the cyclone is extended.Also on display, will be the Multotec 420 high-capacity cyclones which offer significant advantages in reducing maintenance and operating costs. These cyclones are equipped with weep holes to prevent damage to cyclone housings and prolong operational life.There are also the Multotec SX7 coal spirals which are provided with auxiliary splitters that allow for easier control and a more flexible operating range for the discard cut. Spirals are supplied with pipe launders for product collection. Pipe launders are lightweight, durable, spillage free and corrosion resistant.Another highlight on the outside stand is the Multotec Wear Linings display. This group company is intent on showing that ceramic as a lining material can, contrary to popular perception, in fact, withstand impact. A selection of liner panels with ceramics of different thickness embedded in various matrices will be impacted on by a 120-mm rock dropped from a height of 2.5 m. For the purposes of the test, material will be fed by conveyor through a lined chute onto easily interchangeable panels.The working Rondo chute system display discharges material onto a return conveyor, with transfer between feed and return conveyors taking place through a vibratory feeder lined with removable, bolt-on and rubber-backed ceramic liners. The closure of the circuit between the feed and return conveyors at the opposite end is through a Multotec-designed transfer chute. Ceramic pulley lagging will be displayed at the drive and tail ends of both feed and return conveyor pulleys.Multotec Manufacturing launched its injection-moulded modular rubber screen panels for small aperture sizes, a P3P adaptor sleeve for screens with conventional angled runners, a reversible sievebend housing manufactured from high-density polyethylene, which is lighter than conventional steel housings and does not require special linings for corrosive environments and its modular trommel panels for heavy-duty applications, which reduce cost and manufacturing time.Multotec Magnetics, a subsidiary company which specialises in the separation of minerals and materials on the basis of their magnetic properties, is showcasing a number of new developments, including low-intensity drum separators which have been completely re-engineered for improved performance, serviceability and durability. Visitors can also see the new overband tramp removal magnets, which are compliant with underground requirements, and the high-intensity ‘dewatering’ magnet used in dense-media separation circuits and iron-ore beneficiation.
James Harden has become an occupational hazard for referees. Earlier this month, the Jazz were up seven on the Rockets with just over a minute to play, and Utah players were at their wit’s end with the officials. Following a signal that the Jazz had committed yet another foul, Joe Johnson threw his right hand up in disgust. Rudy Gobert shook his head in disbelief. Rodney Hood, who was charged with the foul, looked for a ref with whom he could plead. Joe Ingles had both palms out, confused as to how so little contact could prompt a call.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2017/03/jazz4thfoulagainstharden.mp400:0000:0000:00Use Up/Down Arrow keys to increase or decrease volume.The whistle marked the fourth time that night that Utah had been charged with fouling Harden in the act of shooting a 3-pointer. And while that might sound unbelievable, it wasn’t even the first time this season that the MVP frontrunner had drawn four shooting fouls from the arc in a game.1He also drew four shooting fouls while attempting 3-pointers during a Dec. 31 victory over the Knicks.Harden has long been great at drawing fouls no matter where he is on the court, but he has taken the art form to new heights on his 3-point attempts this season. After drawing 27 fouls while trying to shoot a triple in 2014-15 and inducing 46 such fouls last season,2According to Basketball-Reference.com’s Play Index. Harden has drawn a whopping 108 shooting fouls from distance this year with 11 games left to play. For context, consider that, outside of the Rockets, no team has garnered more than 73 of those calls.3Amazingly, if you limit Harden to just the 12 games in which he drew at least three 3-point shooting fouls, his 38 fouls drawn in those contests would outpace 21 teams’ totals for the season so far.If you subtract Harden’s numbers from the rest of the league’s, the average NBA player has drawn fouls on 1.6 percent of his 3-pointers this season, according to BigDataBall, which tracks the league’s play-by-play logs. Harden is drawing 3-point shooting fouls at a 16.7 percent clip, or more than 10 times as often. How is he so good at this?

Because we as offensive guys, guys who like to score, always try to find tricks that can work in our favor. He found something that’s working for him. So no, as an opponent, I hate it.” (I asked a league spokesman about this issue as it relates to Harden — particularly since the NBA stopped awarding shooting fouls for a similar rip-through move years ago — but he said it’s against league policy to discuss how a particular player is officiated.)Harden isn’t oblivious to the perception that he draws more shooting fouls than he probably should. But the crafty guard makes no apologies, either, saying a defender making contact on a jump shot should merit a foul just like someone bumping a shooter near the basket would. “A foul is a foul no matter how it’s committed,” he told Time in a Q&A this season.Sometimes Harden’s strategy backfires in embarrassing fashion, as he’ll incorrectly anticipate contact and throw up a wild shot in hopes of drawing a foul that never comes.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2017/03/hardenflailing.mp400:0000:0000:00Use Up/Down Arrow keys to increase or decrease volume.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2017/03/hardenflailing4.mp400:0000:0000:00Use Up/Down Arrow keys to increase or decrease volume.But more often than not, it’s been a worthwhile gamble for Harden and the Rockets to go for the foul. That’s become even more true in the past month, since Houston traded for Lou Williams, the player who’s drawn the second-most 3-point shooting fouls in the NBA this season — trailing, of course, only Harden. I asked Houston general manager Daryl Morey about having both of the league’s top two guys in such an odd category, and he said he and others in the Rockets’ front office had noticed Williams’s unusual ability to draw contact from the perimeter, but that it wasn’t the overriding reason they made the swap with the Lakers.“We knew that both Lou and James are extremely good shooters that are hard to guard. So, going over the screen and being physical with them is one of the only ways to guard them, which causes them to get fouled more than others,” Morey said. “That said, we focused more on their overall efficiency than how people have to foul them to stop them.”Teams will do their best to stop Harden from using the trick once the postseason starts. But if last year’s playoffs are any indication, that may not work, either: Harden drew five whistles on just 42 3-point attempts. Three of those fouls came in one half, in a game against the Warriors.Neil Paine assisted with research for this story.Check out our latest NBA predictions.

Unlike Jamal Crawford, who has drawn dozens of perimeter shooting fouls as players barrel into his legs during close-outs, Harden would seem to be the one initiating contact on many of his fouls.In particular, Harden has found a way to turn even solid, respectable defenders into victims. He generally waits until his man puts a hand up to defend, then locks arms with him and jumps to begin a shot, making the defender appear guilty. Harden basically forces perimeter defenders to play with their hands down along the 3-point line.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2017/03/harden4.mp400:0000:0000:00Use Up/Down Arrow keys to increase or decrease volume.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2017/03/harden101.mp400:0000:0000:00Use Up/Down Arrow keys to increase or decrease volume.Back on New Year’s Eve, Knicks coach Jeff Hornacek vented about this after a loss in Houston, saying it’s impossible to defend Harden given his ability to trick officials. “He grabs with his left arm, has the ball in the right hand and wraps his left arm with your hand,” said Hornacek, whose team fouled Harden from 3-point range four times4He drew all four of them in an 18-minute span during the second half. that night while Harden racked up a 53 points, 16 rebounds and 17 assists. “To me, that’s an offensive foul. But he does it fast, quick — it’s hard to see.”Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2017/03/usethisharden16.mp400:0000:0000:00Use Up/Down Arrow keys to increase or decrease volume.The other thing Harden does well: Stop on a dime and pop jumpers just as he’s navigating around screens. That trick makes life hell for the defenders who are sprinting to go over the pick to stay with him. Harden’s world-class ability to stop abruptly means that defenders frequently can’t hit the brakes as quickly as he can, which leads to players running into him from behind, prompting 3-shot fouls. This has been especially true this season, as defenders have tried to stay on Harden’s hip more than usual5Defenses have been guarding Harden more and more closely over the past four years. Opponents have been within four feet of him for 65 percent of his shots this season, up from 51, 61 and 62 percent, respectively, during the 2013, 2014 and 2015 seasons, according to NBA.com. to prevent him from spraying the ball wherever he wants in Houston’s spacious offense.

The U.S. Labor Department also said Friday that 44,000 more jobs were added in September and October combined than the government had previously estimated.Meanwhile, Canada’s unemployment rate nudged up in November to 6.6 per cent as 10,700 jobs were lost last month. However, Statistics Canada said the decline was within its survey’s margin of error and noted that it followed two months of strong employment growth.In other corporate news, the merger between Tim Hortons Inc. (TSX:THI) and Burger King Worldwide Inc. was approved late Thursday by the federal government, with a list of stipulations that include a five-year promise on jobs for employees at its restaurant locations and a continuation of its current community support levels.
