Here is a very smart person, with excellent analytical support/connections, suggesting ideas, weighing them, pointing out the possible pros and cons, offering some thoughtful percentages of success or not, clearly indicating no one can predict the future or the market's reaction to news, and you get to decide to take action or not, at the level you feel comfortable. Most ideas work out and some take longer to work than others. Chris shares his thoughts and ideas, discusses position sizing, offers percentages of his analysis/guessing resulting in being right or wrong, indicates many/most of the risks involved with any suggestions, and reminds you of caveat emptor. SS-21 Silent Sifter ® noise levels are 7–10dB lower than any other rotary sifter.I have been a subscriber for 7-8 years (?) and continue to be highly impressed by the high quality and quantity of Chris DeMuth Jr.'s writing, analysis and responsiveness. Mechanical hammer assembly then taps against each sieve to aid the passage of particles through the sieve cloth. A five-second audible alarm sounds at completion. Two rubber-covered stainless-steel drive rollers continuously rotate the test sieve stack. The ASTM or ISO test sieves are placed in the cabinet, then tilted back to the testing position using the side knob. Rotary sifters do not require the sieve stack to be clamped in place. 635 (25mm-20µm). Silent Sifters ® can instantly convert between 8in, 12in, 200mm, or 300mm test sieve diameter size. A sieve stack is capable of reaching up to 26in (660mm) high, and it can include from six 12in diameter full-height sieves to twenty 8in diameter half-height sieves including a pan. The optimum size range of the Silent Sifter ® is from 1in-No. State departments of transportation often prefer the rotary sifter for aggregate gradations. Time is shown on a large, bright 0.5in (126mm) LED display. The timer features a pause function so the test cycle can be postponed and resumed with no loss of test time. A safety interlock switch disables the sifter and resets the timer if the door is opened during testing.Ī digital countdown timer/controller precisely controls operation up to 99 minutes ☑ second. A dependable 1/4hp continuous-duty motor drives the system. Bearing and rod safety covers further eliminate exposed moving parts below the cabinet for greater compliance with OSHA regulations. Tapping hammer assemblies are 6061 aluminum alloy with Ultra High Molecular Weight (UHMW) Polyethylene heads. Test sieves and drive mechanisms are enclosed by the cabinet to safeguard against injury. The cabinet sits atop a sturdy powder-coated stand constructed of heavy ASTM A513 steel tubing and rolls on 4in hard rubber locking swivel casters for easy mobility in the lab. The full-width cabinet door swings open fully on heavy-duty commercial grade hinges to permit easy loading and unloading of test sieves. The cabinet is a high-quality CNC machined MDF board, precisely fitted to confine and control airborne respirable quartz, silica, crystalline particles, and other nuisance dust to further protect personnel and permit easy cleanup. The tightly sealed cabinet uses sound-deadening materials and a proprietary design to limit noise during operation. Gilson's proprietary silencing technology has resulted in units with noise levels 7–18dB quieter than standard rotary sifters. They significantly reduce operational noise levels with no loss of particle sizing accuracy and performance. Silent Sifters are the newest laboratory sifter models that reflect today's emphasis on noise reduction and worker protection in the laboratory environment.
