While using bucket elevator, sometimes there is abnormal holdback operation phenomenon during operation, do you know the reason? In fact, during the operation of bucket elevator, sometimes there will be operation stopping inevitably due to malfunction or heavy-loading, even the breakage of link chain or belt could occur, then cause reversal. The reverse operating can cause collision of the bucket and material that remain in the bottom, this could easily cause deformation of bucket and will not function well due to severe damage. Overloading situation is easy to occur if not pay attention to feeding capacity. Under normal circumstances, the bucket of bucket elevator will lift the material from the bottom to the discharge port which is located on top of bucket elevator and then throw out. In order to ensure the production, when designing and manufacturing equipment, manufacturers just consider that the equipment will not reverse under the non-load condition, because bucket of lower part is two more than upper part, which will be much heavier than the upper. In order to prevent the breakage of belt or link chain or reversal occur in the bucket and link chain, especially when the bucket elevator is under the overload condition, the backstop should be installed at the external of bucket elevator in order to avoid the problem of overload. The bucket elevator holdback consists of reverse rod, revolving shaft, retracting spring and dowel pin etc. In the process of normal operation of bucket elevator, the reverse rod will be upswing after hit by the sleeve, it will fall under the action of retracting spring force, then upswing after hit by another sleeve, not affecting the normal operation of equipment. If there is reversal of bucket elevator, the dowel pin will halt the reverse rod, so it will no longer swing down, and the sleeve will also be blocked by the reverse rod, hence the whole link chain could not reverse. If there is too much material spilled inside the body of machine and fall on the reverse rod, it will cause the failure of holdback. If there is too much materials outside the bucket elevator, it will affect the rotation axis of screw. We may see there will be stacked with material in the pit of bucket elevator on the users site, which will seriously affect the operation of the relevant parts of holdback.
With continuous bucket elevators (or bucket conveyors as they are often called), the term Carryback is used to describe the incomplete emptying and discharge of material from the buckets. Incomplete emptying of buckets results in material remaining in the bucket following discharge and being carried back through the elevator. Carryback material eventually deposits on ledges and surfaces within the conveyor frame, while traces may also remain in the buckets. Accumulation of the material within the conveyor frame can lead to potential mechanical problems such as off-tracking or in severe cases damage to the buckets or other components.
Addressing carryback, when it occurs, requires first determining the cause. When buckets do not discharge completely, and material is being carried back through the elevator, it could be due to the following reasons:
The material being moved has a tendency to cake and pack once loaded into the elevator buckets. When handling these types of materials, it is not uncommon for some residual material which has become caked or packed to remain within a bucket following discharge.
Different bucket plastic materials can be selected to provide the best product release properties while still maintaining other requirements such as conductivity, extreme temperature or abrasion resistance.
When handling materials which are prone to accumulating a static charge, causing it to adhere to the buckets, consider using elevators with fully conductive bucket assemblies. Conductive bucket assemblies help discharge static, allowing material to fully release from the buckets.
Applicable flow aids such as a bucket discharge assist device (bucket thumper or bucket knocker), whose pendulum mechanically impacts each bucket at discharge, thereby loosening material and directing it back into the discharge flow of the elevator.
As with any equipment, routine inspections are required. As most Bucket elevators are fully enclosed for safety reasons; Inspection windows, doors and removable cover panels in strategic locations allow your maintenance personnel to perform these routine inspections and provide the necessary access for cleaning.
Clean-out drawers are also available to allow for some accumulation of the carryback material which can then be easily emptied. The above tips will help to troubleshoot bucket elevator carryback when it occurs. Implementing many of these solutions onto an existing installation will likely require retrofit assistance from the OEM who supplied the elevator. However, an ounce of prevention is always worth a pound of cure. Reducing bucket elevator carryback requires working with equipment suppliers who have the know-how and equipment solutions to properly address the issues and reduce the frequency thereby preventing serious issue from happening in the future.
At UniTrak, we have over 45 years experience in helping customers to move even the most difficult-handle materials effectively and efficiently.TipTrakTMbucket elevatorsfrom UniTrak have design features and options to successfully prevent and address bucket elevator carryback. In every project requiring a bucket elevator, we carefully review the application requirements and, where appropriate, conduct material tests to determine the risk of carryback occurring. From there, we propose an equipment solution which includes specific options to prevent carryback. These options may include the provision of buckets especially designed to prevent material adherence and the inclusion of suitable flow aids where needed.
Youve purchased and installed a continuous bucket elevator and everythings running fine until Murphy strikes and your elevator and line are halted. What now? Unplanned maintenance interventions, frantic calls to the manufacturer, whatever it takes to get the elevator back up and running. While bucket elevators from reputable OEMs are dependable machines, such unexpected scenarios can happen, and often they can be avoided. This blog highlights the top three reasons that can bring a continuous bucket elevator down, and offers guidance for avoiding these problems.
In many facilities, continuous bucket elevators are workhorse units. In these settings, it is often easy to overlook performing vital Preventive Maintenance (PM) activities. Failure to perform needed PM activities results in parts and components being pushed beyond their expected life-cycles, with resulting parts failure and attendant unplanned downtime.
In a January 2017articlewhich appeared inPowder Bulk Engineeringmagazine, John McDonald, Service Team Leader at UniTrak, highlighted the need to follow an OEMs recommended PM activities and schedule. In that article, John also discussed particular aspects of a continuous bucket elevator that should be regularly inspected to detect signs of premature wear and tear that could lead to failure. This need becomes even more acute in severe service settings where aggressive materials are being moved or the equipment is being used in extreme conditions and temperatures.
Material which spills from buckets as it transits the elevator, or which accumulates in the infeed area due to poor material feeding, can build up to the point where machine operation is halted. Accumulated material can cause buckets to be torn loose from their mounting fasteners, or block the progress of buckets through the elevator, resulting in an overload situation and consequent machine shutdown.
As noted above, continuous bucket elevators from reputable manufacturers are dependable units that can offer excellent uptime and availability if certain basic practices are followed. Following the tips above can help ensure you avoid the problems described above and reduce unplanned equipment stoppages.

Muller Beltex has many years of experience and global expertise in the bulk and process industry. That is why we, as a renowned knowledge and service provider, are often approached by equipment manufacturers and end users who are encountering problems with their equipment.
Their questions may involve durability, the wish to reduce excessive wear or capacity issues. In this article, we will enter into a specific problem we often come across in more older elevators used in the agricultural sector, which is product taken down again in the return part of a bucket elevator, so called back-legging. What does this mean?
Product that is not correctly or not discharged from the elevator bucket and is therefore dropped back into the down-going elevator leg. This may be because the elevators were designed for example in the nineteen eighties for a capacity of 70 tons per hour at a certain belt speed and the elevator was fed in the up-going elevator leg. At the time, only one type of product was transported with the elevator in question. However, over the following decades, the tonnage may have been increased to perhaps 100 tons per hour, transporting multiple products with a variety of densities at the same belt speed.
In addition the feeding of the elevator could be both in the up-going and also in the down-going leg of the elevator.Because the product is ending up in the elevator boot section, the buckets need to dig up the product from the boot of the elevator, which leads to unnecessary wear and additional stress on the bucket elevator components and the required capacities are no longer realised.
Extensive inspection of the installation allows us to study the problems. We analyse the existing situation and draw up a plan of approach in consultation with our engineering department. This plan of approach is presented to our customer, together with a specified quotation.
Expert calculation of the correct drive and return pulley, elevator bucket, bucket formation, belt speed, and if applicable, adjustment of the construction itself allows us to successfully solve complex problems like the one described above.
