·FEM ANALYSIS OF A BELT CONVEYOR DRIVING DRUM 1A Mihailidis 1E Bouras 1E Athanasopoulos 1 Aristotle University of Large scale belt conveyor systems have a lot of unique characteristics such as long conveying distance large capacity and high efficiency continuous transportation of bulk materials as well as central control and
·Belt Conveyor Design Guide Selection and Specification for Optimal Performance In this essential section of the Belt Conveyor Design Guide we delve into the process of selecting the right conveyor belt for various applications guided by the conveyor belt selection the appropriate belt type is critical for ensuring the efficiency safety
·As a rough guideline use 1 5 % elongation for textile belts and 0 2 % for steel cord belts Note For long distance conveyors dynamic start up calculations may be required because not all elements are set in motion simultaneously due to
·Conveyor belts are a tried and true energy saver designed to increase efficiency Let s take a look at how conveyor belts work and why they ve stood the test of time How a conveyor belt Works A conveyor belt works by using two motorized pulleys that loop over a long stretch of thick durable material
Design/methodology/approach Loads on the driving drum are determined from measurements of the bearing force and the motor power The friction interaction between belt and drum is described by the creep model and its impact is evaluated by comparing the results obtained for low and typical values of friction coefficient
Conveyor Drums by ELCO Conveyors This is the most common style of conveyor drum manufactured for all styles of belt conveyor Elco Conveyors can produce thin light guage conveyor drums in ø50 ø60 63 ø70 ø76 ø80 ø89 ø102 ø114 and ø127mm with walls and an unmachined finish To complement the range we also produce heavy
2 ·Function of Snub pulley on conveyor belt The snub pulley tensions the conveyor belts forcing the belt to wind a little more onto the nearest drum The sole aim is to increase the contact surface between the belt and the drum pulley concerned On a conventional conveyor for example the winding angle is around 180°
Conveyor belts are frequently blamed for belt tracking problems and in most cases this is unjustified The failure cause is usually to be found in the installation itself and may be the result of poorly adjusted pulleys and rollers incorrect application of belt tracking measures or faulty design It is therefore essential to be fully aware of
·Conveyor belts also called belt conveyors are used to move goods and products that require greater stability or that due to their size or characteristics can not be transported with roller conveyors Although the basic operating principle may seem simple the movement of a belt because of the rotation of drums or pulleys in turn driven
·Conveyor belts are made up of four main components a wearresistant rubber top layer a carcass to provide tensile strength and toughness steel or fabric rubber layers for adhesion between the
·A conveyor belt is the moving part of the belt conveyor that carries the product or materials There are many different types of conveyor belts to handle the wide variety of things that need to move Flat Conveyor Belt The flat conveyor belt is the most common and simplest type of conveyor system
·2 Specific Conveyor Types and Their Hazards a Belt Conveyors Hazards Drive Mechanisms The moving belt interacts with drive components creating nip and shear points where severe injuries can occur Take Up and Discharge Ends Areas where the belt tension is adjusted or where materials are loaded/unloaded can pose significant risks Pulley
·A conveyor belt is the carrying medium of a belt conveyor system often shortened to belt conveyor A belt conveyor system is one of many types of conveyor systems A belt conveyor system consists of two or more pulleys sometimes referred to as drums with a closed loop of carrying medium—the conveyor belt—that rotates about them
·The effect of sharp heavy material falling onto a conveyor belt cover to loosen or tear out pieces of the cover Photo Gradient There is a wide choice of conveyor belts for all gradients From normal troughed conveyor belts via pipe conveyor belts through to vertical elevator belts Table Gravity take up
Belt slippage on drive drums of belt conveyors is generally considered as an undesirable phenomenon which has a huge influence on wear of the drive drum lining or its destruction reduces the operability of the entire device and should be then completely excluded from belt conveyor operation Belt slips in the start up phase can be longor short lasting with slight
·The following is a quick chart of some common conveyor belt hazards including various parts of a conveyor and associated risks with each Component Purpose Expected Hazards Dangers Pinch Points Also known as Nib Points pinch points are rotatory parts in a machine providing a common meet point for two individual conveyor surfaces/rollers
·Drum as a belt conveyor drive components attracted the attention of the relevant technical staff To ensure the belt conveyor system the optimizing design of the drum quality and the strengthen
2 ·For example axle bearings welded axle or axle with a clamping sleeve construction cylindrical or rounded drum and static or dynamic balance Possibly with the desired coating Cage drums Like reversing drums cage drums are used for tensioning and reversing the conveyor belt Cage drums have a cage consisting of steel ribs around a
Angular speed is commonly expressed in revolutions per minute RPM or radians per second It tells us how fast a drum or wheel is spinning To calculate the angular speed of the drum when the conveyor belt reaches a speed of 3 feet per second we need to convert the linear speed to angular speed using the relationship v = romega where v is the linear speed omega
·The drum motor conveyor belt drive design entered the market in the early 50 s What sets the drum motor apart from a conventional conveyor drive is that the drum motor has all drive components including the electric motor gear reducer and all bearings housed inside the drum Without any exposed drive components and with no other
·the movement of a conveyor belt through a drive drum was modeled Conveyor belt is a very im portant part of belt conveyors [7][8][9] Convey ors are used in many industries due to their prop erties Belt conveyors belong to the most manag ing types of conveyors [10] They are engineered for sophisticated conveying of material and they
·conveyor belt and Fatigue cracks initiated at the toes of the welds between the plates and the bosses and propagated through the plates until the shell became detached from the shaft [14] 6 Fatigue in the shell of a conveyor drum The shells of a belt conveyor broke in operation due to fatigue in the area of the weld seam between the axle
