How To Reduce Noise From Drag Conveyors
The biggest noise reduction is achieved by closing most of the landing gear doors again after extension is complete Of the factors that influence drag and noise, one is the distance between wheel and fuselage The picture below is taken from S Hoerner's book "Fluid Dynamic Drag", chapter XIII5 of which deals with the drag of landing gearsA conveyor drive consists of three basic elements: the structural framework, conveyor rollers and a drive mechanism, such as a motor connected to a Falk gearbox Fortunately, there are many ways to control the noise emitted by a conveyor drive, such as by making sound dampening modifications to the gearbox reducerGearbox Reducer Vibrations: Reducing Conveyor Drive Noise
Noise levels generated by a typical lineshaft conveyor systemwhose sources of noise include shaft clatter, bearing rattle, and roller tube ringingcan exceed 70 dBA By applying various noise reduction strategies in this newest generation of conveyor systems, engineers have been able to achieve decibel levels in the low 60'sall the moreUnaceptable noise on drag conveyor Hello Gentlemen, We have very noisy new flat bottom drag conveyor in bentonite (60lb/cuft) with the following specs: 14'' width, 105 ft length, cap 6,300 cuft/hr, chain speed 80ft/min 40hp UHMW 1/2'' flights WR132 chainUnacceptable Noise on Drag Conveyor bulkonline Forums
CONVEYOR NOISE SPECIFICATION AND CONTROL Brown, SC Heggies Australia Pty Ltd, Sydney, Australia Abstract Large, outdoor Belt Conveyor SystemsReducing noise in a dragline cab (case study #25) A company using tracked draglines in quarrying found that drivers were being exposed to Aweighted noise levels of 96 to 100 dB The particular problem was that the main drive engine was located in the same all steel 'box', separated from the driver's cab only by a sheet steel bulkheadHSE Noise: Sound Solutions Case Studies
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
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

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
Reducing noise on the output of a switching regulator Introduction Compared to linear regulators, DC/DC converters provide great efficiency for voltage regulation However, they have an undeserved bad reputation when it comes to systems with sensitive signal paths because of the noise they can generate On top of their outputripple noise, theyLike our conveyors, bucket elevator conveyors reduce noise, are energy efficient, and reduce degradation like tube conveyors Additionally, Cablevey Conveyors offer enclosed tubing to protect materials from loss and contamination, flexible layouts and are easy to sanitize and cleanA gentle reminder Cablevey® Conveyors
Avoiding impacts [extracted from L108 "Controlling noise at work" p5758] [1] Reduced dropheights and cushioned impacts reduce noise Noise generated by impacts, including components falling into chutes, bins and hoppers, and impactsDear Peter, Q1: same opinion as Paul Holt, maybe additionally: the power consumption can be approximately 13 17 times higher Q2: Pipe Conveyors are definitely very quiet along the conveying route and there are some tricks to even reduce the very low noise as using rubber plates when fixing the idlers on the frame or using idlers with greater diameter to reduce the rotation speedPipe Conveyor Investment Cost / Noise Emissions
