  • Drag Chain Conveyor Problems: Keeping it Moving

    Drag chain conveyors can operate in three planes which allow complex circuits eliminating transfer points and using only a single drive They have minimum horsepower and energy consumption when compared to pneumatic conveying systems with equivalent rates They can be meter or flood fed They have minimal noise levelsAgain, by reducing drag and noise over the sailboat 500, the efficiency of the sailboat 500 may be increased It will be appreciated that flocking may be attached to powerboats (ie, no sails or sails in combination with an engine) whereby flocking will serve to reduce the drag over the boat and thereby reduce fuel consumptionMethod and apparatus for reducing drag and noise for a

  • Top 10 noise control techniques HSE: Information

    The following are 10 simple noise control techniques that have wide application across the whole of industry In many cases, they will produce substantial noise reductions quickly and cheaply with little or no effect on normal operation or use 1 DAMPING Typical applications Chutes, hoppers, machine guards, panels, conveyors, tanks The lower chain speeds reduce frictional wear issues and chain wear, require lower horsepower requirements for the conveyor, and minimizes overall power consumption One of the big advantages of an EnMasse drag conveyor is the highefficiency ratioTech Brief: Drag Chain Conveyor Operation CDM

  • Industrial Noise Reduction UK | Noise Control | Machine

    A company quoted £130,000 to reduce noise from air conveyors (airveyors) by installing noise control enclosures The customer chose our company instead Our sound solution was very successful, suppressing the noise by 6 dBA and reducing it below the 85 dBA target Our noise solution cost only £2500, saving £127,500 Air Knife“Tubular conveyors generate minimal dust due to the gentle, low velocity, so there is often no requirement for a dust handling system at the end, such as a bag station used to filter and clean the air,” adds Schliebs Without highspeed contact or scraping, the lower speed, lower energy motors of tubular drag conveyors also reduce sparkingCareful Conveying To Avoid Accidental Ignitions | Engineer
