plasterboardbelts. lutze offers a complete, highquality sling system. conveyor belt eastman rock crusherthe belt conveyor used in industries area structure &parts belt conveyors have the advantages of large conveying capacity, long conveying distance, stable conveying, no relative movement of materials and conveying belt, low noise, simple structure, convenient maintenance, low energy consumption, and standardization of components. belt conveyor maintenance 101 plant servicesone of major problems in belt conveyors is misalignment and deviations in the structure, frames, and foundation. the conveyor frame or structure might be crooked or deformed. there have been many different forms and types for such problems, and there can be many different patterns and combinations of such deviations and deformations. the structure should be corrected and straightened in the affected areas. 1. read "5 steps to creating a parts plan that will keep your lines moving"in many cases, the structure is not level. sometimes, the structural problem or deformation is because wrong type of fasteners are used or fasteners are too tight or too loose. in other cases, the structure or frame might not be strong enough to resist deformations and deflections under loads. in those cases, the structure or frame should be reinforced. see full list on plantservices.com the second source is the misalignment imposed by idlers or pulleys due to many different types of issues and problems. idlers or pulleys can be outofsquare with the belt centerline. idler stands might not center on the beltin these situations, idlers or their stands should be readjusted in deviated areas. in general, too long distance between idlers has caused many problems. an optimum idler spacing is always recommended. excessive sag of the belt between idlers can be an indication of long idler spacing or low takeup tension. this causes bulk materials to work and shuffle on the belt as it passes over idlers, which can cause other problems such as material slippage. the solution is the reduction of idler spacing, more belt tension, or both. when the idler is not perfectly aligned with the belt, additional loading on the idler and additional drag on the belt can be introduced. when an idler is installed higher (elevated) than the adjacent idlers, the belt tension will add load see full list on plantservices.com another source of misalignment is the belt itself. for example, the belt might not be joined squarely, where poor splicing leads to misalignment. in most cases, the problematic splice should be removed, and the belt should be respliced. bowed belt is another widely reported problem, including for new belts. this condition may disappear during breakin. however, in many cases, the belt should be straightened or replaced. belt edges may fold up on structure. the clearance should usually be adjusted and often more clearance is needed. the cover of the belt is an extremely important part of the belt, and this cover should be selected after thorough review of handled bulk material and associated wear and damaging mechanisms. in many cases, the cover material may be wrongly selected, the thickness too small, or the quality was too low. this can be very problematic as if the cover is worn, the tensioncarrying layers of the belt can be damaged, which can lead to a wide range of operationa see full list on plantservices.com the route, profile, and transitions have been known as another source of misalignment or generally operational problems. smooth transition between different set of idlers or idlers and pulley are key for proper operation and reliability of a belt conveyor. in particular, an improper transition between the troughed belt section and terminal pulley(s) has been reported as the root cause of many problems including misalignment, and it is often necessary to adjust such transitions. severe convex (hump) vertical curve also can be challenging. idler spacing may be decreased in such a curve. it is always beneficial to increase curve radius. see full list on plantservices.com a major source of misalignment is the loading. offcenter loading or poor loading have frequently been reported as the main source of induced misalignment. ideally the chute or loading devices should load the bulk materials on the center of the belt at or near belt speed. however, in real operation, there can be deviations and some degrees of offcenter loading. if considerable, this offcenter loading can drive the belt to misalignment and can cause operational problems. the solution is to adjust the chute and other loading items to reduce or eliminate offcenter loadings. as the loading system is often complex and consists of many different parts and components (chutes, skirtboards, etc.), all of them should work in concert for proper, oncenter loading. skirtboards improperly adjusted or of wrong material can cause many different operational problems including misalignment. the dimensions, gap, and tolerances should be adjusted properly. the contact between metallic parts and b see full list on plantservices.com slippage of the belt on the drive pulley can occur on a belt conveyor. one option to solve this problem is to increase the takeup tension (belt tension)however, there can be limits, and toohigh tension in a belt can usually cause another set of problems. for instance, sometimes high belt tension can lead to liftoff of the belt in certain areas. a better solution to fix slippage on drive pulley is to increase the arc of contact. another solution is to apply a better lagging for the pulley. the pulley lagging might wear in a short time, and in such a case they should be replaced with a new or better one. in general, insufficient traction between the belt and drive pulley is a major problem, which can be intensified by wear and tear over time, dirt and debris, and other operational effects. certain safety margins such as higher belt wrap or better safety factors should always be considered. often pulleys are selected that are too small, which causes problems such as excessive belt see full list on plantservices.com a key question to ask when dealing with the belt misalignment is how a belt conveyor performs in different operating conditions. in particular, it should be clearly determined how the operation and misalignment is affected in different empty, loaded, and fullyloaded conditions as well as when the load varies. a normal training sequence starts with the return run working toward the tail pulley and then following with the top run in the direction of belt travel. the process should be started with the belt empty. after tracking is completed, run the belt with a load and recheck tracking. it is often recommended to complete tracking in three steps: (1) minimum possible load, (2) a step between the minimum and fullload, and (3) at fullload. tracking adjustment is done while the belt is running and should be spread over some length of the conveyor preceding the region of trouble. the adjustment may not be immediately apparent. the belt should be operated for several minutes and at leas see full list on plantservices.com a particular challenge with belt conveyors is that multiple deviations and issues can be combined to produce a complex situation, and this combination of problems sometimes produces cases where the root cause of failure is not clear. however, if there are a sufficient number of belt revolutions, the running pattern may become clear. in cases where a running pattern does not emerge, it is strongly suggested that the full tracking procedure should be employed. it is quite likely that the erratic performance will be resolved in the process. there have been many cases that after many attempts and correction, the belt will still run offcenter around the tail pulley and through the loading area, or the belt may even be hitting the structure. for such cases, training idlers might be used. conclusion a systematic approach is needed for the alignment and tracking of a conveyor belt. the first step is to examine some of key components of the belt conveyor system such as structure, frames, an see full list on plantservices.com conveyors crushing plants worldcrushersapr 18, 2013 · rollers on
