How does a bucket elevator workBucket elevators are conveyors that carry bulk materials along an inclined or vertical path. The bucket elevators for vertical and mechanical transportation of goods has become an important link in production processes for several industrial sectors.
Materials are first fed into a type of inlet hopper. The cups or buckets dig into materials, which are then conveyed up and over a pulley or head sprocket, followed by throwing the materials out of a discharge throat. The empty buckets then continue this cycle by returning back to a boot.
The Industrial Bucket Elevators come in various sizes, weights, and shapes, using either continuous buckets or centrifugal buckets. The belt is usually made from metal, plastic, rubber, or natural fibers.
The Centrifugal Bucket Elevators are more commonly used for conveying free-flowing materials. These buckets operate at high speed to throw materials out of the buckets inside a discharge throat using centrifugal force.
Continuous Bucket Elevators operate at a slower speed and include buckets that are evenly spaced. The buckets' even placement lets gravity successfully discharge loads onto an inverted-front of a preceding bucket. These buckets will then guide the materials into a discharge throat along the elevator's descending side. This minimizes product damage or is used to handle fluffy, light materials whereby aeration of the materials needs to be avoided.
The motion of a chain or belt is un-directional. Bucket elevators are simple yet extremely reliable devices for lifting bulk materials. Bucket elevators share a few benefits, which include the simplicity of fabrication and design, the initial investment is low, and they require minimal floor space.
Theres a reason bucket elevators are so popular. Theyre good at their job. In fact, theyre one of the most effective ways to vertically transport bulk materials. Bucket elevators are also adaptable, with the capacity to work with thousands of applications. This versatility, however, makes it difficult for vendors to deliver a one-size-fits-all solution.
Ideally, every bucket elevator should be built specifically for its own production line. This means working with a vendor on a custom solution. We know the process can be overwhelming, which is why weve put together this handy guide. Well be covering:
Most bucket elevators are built for a specific application, but premium vendors will insist on a completely custom solution for their customers. Going the custom route means a greater upfront investment, but youll benefit from having a bucket elevator thats not only tailored to your product, but your facilities as well.
Configuration is considered a subset of the design. It refers to the specific layout of your bucket elevator, particularly in relation to the fixed upstream and downstream equipment that it must connect to. Two of the most common configurations for bucket elevators include Standard (Z-shaped), and Standard C (C-shaped). At UniTrak, we also offer: Incline Incline-Horizontal Stair Step Lowerator
Working off the base model, the next step is to select which additional features will be incorporated into the custom bucket elevator design. At UniTrak, for example, our customers may choose from the following:
At UniTrak, the customization process begins once a particular model has been selected. We build every TipTrak to order, using standard components, according to our customers application requirements and the optional features they selected.
Theres a lot to consider when sourcing a customized bucket elevator solution. Working with vendors who have a track record in custom design will make the process easier. Theyll know which questions to ask to fully understand your unique application needs and make the best recommendations possible.
At UniTrak, we have 50 years of experience designing and building bucket elevators for manufacturers worldwide. We would love to hear about your application, and how we can help you find the best solution with a customized bucket elevator. Click here to get in touch with our team.
Whether replacing an existing bucket elevator, or building a new plant altogether, there are a few crucial decisions the purchaser should be prepared to make during the buying process. Here are some of the key design decisions that will require consideration when engaging a bucket elevator supplier.
Bucket elevators are primarily manufactured in two different discharge configurations: centrifugal and continuous. One of the first questions a bucket elevator manufacturer will ask is which elevator style the project calls for.
Continuous-style bucket elevators operate at slower speeds and lower capacities, offering gentle handling for materials that are fragile or susceptible to aeration; they are the preferred choice for applications such as potash and other fertilizers where degradation or attrition is a concern.
Continuous bucket elevators are also the best choice when handling materials that are either abrasive or inconsistent in particle size; the scooping and throwing action of the centrifugal-style elevator does not lend well to these types of materials.
Material is fed from a chute into buckets as they pass through the boot section. Buckets are designed and arranged in a way that allows the back of each bucket to serve as a discharge surface onto which the previous buckets material passes, making its way to the discharge chute via gravity.
Centrifugal-style elevators are better suited to faster, smoother handling applications where degradation or aeration of material are not a concern. This type of handling is typical of free-flowing or powdered materials and is often used for sand and ore.
The centrifugal elevator style self loads by scooping material from a hopper as it passes through the boot section. On passing over the head pulley, the buckets discharge material by throwing it into the discharge chute via centrifugal force. This elevator type operates at higher speeds and accommodates greater capacities, and as such, is the preferred choice at shipping terminals and other high-volume settings.
Centrifugal Bucket Elevator The image above illustrates the operation of a centrifugal-style bucket elevator. Note how loading is primarily a result of the buckets scooping material and discharge occurs as a result of throwing via centrifugal force.
The bucket elevator manufacturer will also want to know whether a belt- or chain-type elevator is preferred. Both belt and chain bucket elevators offer a reliable handling solution, with the decision between the two types coming down to practicality and cost.
Belt elevators offer a cost-effective solution for applications such as sand handling (a centrifugal belt-style elevator with nylon buckets offers a highly effective and economic option in such settings). They are also the preferred choice when noise is a concern, as they are much quieter than their chain counterparts.
This elevator style does, however, have some limitations. While less costly, they are not as durable as chains, making them less of a fit for especially demanding applications, such as those found at mine sites. They are also not recommended when the material to be handled is hot, or presents a risk of combustion. Further, since large particles could become wedged between where the bucket is mounted onto the belt, causing damage, the belt-style elevator is best suited for smaller particle sizes ( roughly and smaller) that avoid this risk.
While smaller belt elevators can handle capacities comparable to that of a chain elevator, this is only true up to a point; in addition to a lower tensile strength, their capacity is limited by practicality; beyond a certain capacity, the size of the casing and components required would be impractical.
Chain elevators are also the best option for handling higher-temperature (greater than 400F) or potentially combustible materials, as well as materials of a larger particle size that could otherwise become lodged between a bucket and belt.
A well-chosen bucket style often means the difference between seamless production and constant downtime for bucket repair or replacement. Elevator buckets are available in a wide range of styles and materials depending on whether the chosen elevator is of the continuous or centrifugal design.
Since centrifugal elevators will require the buckets to scoop up material, buckets in this category are equipped with a reinforced lip on the leading edge in order to discourage any distortion during digging.
AC Buckets are chosen for especially heavy-duty applications, or when the material being conveyed is hot or highly abrasive. This bucket style also accommodates a much higher capacity than the AA bucket style.
Close-centered, or CC buckets are an increasingly popular bucket style for centrifugal elevators. The buckets unique shape, along with a design that allows buckets to be spaced closer together, offers additional capacity over what AC buckets can handle.
Inspection doors are important for troubleshooting or routinely examining elevator performance and the overall condition of the equipment. Further, some operations may require access doors that allow for easy access to the units internals for changing or cleaning buckets, shoveling or washing out the boot section, or other routine maintenance procedures.
Bucket elevators typically come with access doors at the boot section and inspection doors at the head section, but additional access or inspection doors may be helpful at the intermediate sections as well, depending on the applications. Depending on where the bucket elevator is located in the plant, and the surrounding infrastructure, ladders and safety cages, as well as platforms may also be necessary.
The purchase of a new bucket elevator requires several design decisions on the part of the purchaser. For those new to bucket elevators, FEECO can walk you through the process and provide guidance on critical decisions based on your handling requirements and goals.

If you are looking for a machine that can move bulk materials vertically, it is a pretty good chance you need a bucket conveyor. These machines will grant you a more efficient process flow, but you have to understand the design functions. Critical information to know is how your material will be affected with this machinery, and the three choices you have in choosing the correct bucket elevator.
Bucket elevators move bulk material vertically much like the conveyor belt. Buckets are attached to a rotating belt and fill with the material at the bottom of the elevator then move it to a designated point. When the bucket reaches this point, it discharges the contents, returns to the start point, and begins the process again. Buckets prevent spillage with their upright position design. There are three types of bucket elevators to choose from.
Configurations for bucket elevators get engineered for different applications. Depending on the kind of material you want the conveyor to move, the horsepower it will take to run it, and how high the elevator will go determines which type of elevator to use. The options open to you are centrifugal bucket elevators, continuous or positive discharge types.
The Bucket Conveyor process works best for dry, dusty material. These machines will also work well for heavier, more challenging material such as those found in mining operations. It is not recommended that you use this system if your material is wet, sticky, or has a sludge consistency. The build up these materials can create discharge issues during your process.
The type of material you have will determine if a Bucket Conveyor is your best choice. These machines are capable of handling a large number of different products such as heavy, fragile, abrasive or light; however, only free flowing material should be used. Other factors concerning your material are the size, moisture level, and density which will play a big part in creating a bucket conveyor that will work efficiently for your job.
The capacity rate tells you how much material moves through the Bucket Conveyor. When you are ready to have your machinery designed, you will need to ensure it is created to maximum capacity to get full utilization of your bucket elevator. Your goal is to secure the proper unit is to attain the best possible capacity rate output.
Designing a bucket elevator for you also requires knowing the desired height you will need the material lifted. When you take the type of material you are moving, combined with the capacity rate, and know the overall bucket elevator height will create the perfect bucket conveyor system for your operation. Include the size of the facility with your order to ensure the system will fit into your space.
Bucket conveyor systems are used in many industries today and serve a variety of purposes. These systems have a large transporting capacity with much lower maintenance rate. These machines are durable with little driving power and transport material quickly and smoothly. Choosing this system for your operations will ensure a reliable source of transportation that will function more efficiently.

Bucket elevator is a kind of conveying machine, bucket elevator usually uses a series of buckets which are uniformly fixed to the endless traction chain or belt to continuously lift bulk or broken materials in or near the vertical direction.
The bucket elevator working principle is relatively simple, mainly relying on the bucket hoppers fixed on the chain (belt) to lift the materials flowing evenly into the tail feed port from the tail of the bucket elevator to the head of the bucket elevator uninterruptedly, and then unload the materials from the head outlet to complete the whole lifting process of the materials.
Bucket elevator is widely used in mining, metallurgy, building materials, coal, hydropower and other industries to vertically lift bulk, granular, powdered materials with a diffuse pressure of less than 250 , such as ore, coal, coke, cement, stone sand etc.
Bucket elevators are mainly used for vertical transportation of powdered, granular and bulk materials, which can be divided into many types. The three common bucket elevators include: Link Chain, Plate Chain and Belt Bucket Elevator:
The bucket elevator with chain structure uses quasi-ring chain as traction component, and the connection between buckets is relatively strong. Suitable for conveying powdered, granular and small bulk materials, such as cement, gravel, sand, chemical fertilizer, etc., the temperature of conveying materials can reach 250 .
The plate chain bucket elevator has the advantages of light weight, strong structure, fully sealed shell, low chain speed and no material return. It is suitable for lifting large amount of materials, and the temperature of conveying materials can reach 250 .
The belt bucket elevator adopts a special design, with tear-proof high-strength steel wire rope core belt, with special belt joint and bucket fixture to make the belt can run reliably for a long time. The temperature of ordinary belt material does not exceed 60 , steel rope belt allows up to 80 , heat-resistant belt allows >120 .
The choice of buckets is mainly based on the humidity and viscosity of the material. The shallow bucket is suitable for conveying materials with poor moisture and fluidity, while the deep bucket is suitable for transporting materials with dry and good fluidity.
The traction parts of the bucket elevator is an important part to realize the material lifting, which is generally determined according to the elevation of the user and the temperature of the material.
Belt bucket elevator has higher rotational speed and lower cost, but the strength of the belt is low and the lifting height is not large. On the contrary, chain bucket elevator can lift the materials with larger block size and higher temperature.
The material loading mode of bucket elevator is mainly divided into two types: Cut-Out type and Flow-In type, the choice of both mainly depends on the characteristics and running speed of the materials.
The cut-out type is mainly used for conveying powder, granular and small bulk materials without grinding or semi-grinding, with a high running speed of 0.8-2.0m/s; The flow-in type is used for conveying bulk and grinding materials. The running speed is low and generally does not exceed 1m/s.
The material unloading mode of bucket elevator is divided into centrifugal unloading and gravity unloading, which is selected according to material characteristics, running speed and traction parts types.
Gravity unloading is suitable for transporting bulk and grinding materials, and is suitable for vertical or inclined bucket elevator with continuous arrangement of buckets, the running speed of buckets is about 0.4-0.6m/s.
The installation mode of bucket elevator needs to be based on the on-site conditions of users, and vertical bucket elevators are usually used. The inclined bucket elevator is used only when the vertical bucket elevator can not meet the special requirements, because the supporting device needs to be added when the tilt angle is too large, which makes the structure complicated.
Technology infiltrates every aspect of our lives. As more modern gadgets are introduced, they start to find places in our daily operations. This doesnt just affect us on a personal level, but also on a professional one. Many industries and manufacturing businesses are investing more and more in new technology to make operations run more smoothly.
One such piece of tech is known as the bucket elevator. Sometimes called a bucket conveyor, the bucket elevator has numerous industrial applications. If you want to move a type of material vertically, this type of elevator can help.
In this type of elevator or conveyor system, a number of buckets are connected to each other. This is typically done on a strong chain. The way the elevator (either a continuousbucket elevatoror a centrifugal bucket elevator) works is through the movement of that strong chain. As the chain or belt is rotated, the buckets are driven upwards or downwards. Of course, the term elevator comes from the vertical movement. Depending on the design, speed, and capacity of the bucket, the system will either work more or less efficiently.
Perhaps the biggest advantage of the bucket conveyor system is its ability to transport materials much more easily. The bucket is also capable of much more gentle handling than workers are. A manufacturing facility that has a continuous bucket elevator can transport large amounts of materials much more easily and it can easily give a business a leg up on the competition in terms of sheer transportation capacity.
Depending on the hopper or bucket you choose, your elevator can haul bulk material with its ongoingcentrifugal force. Plus, since bucket elevators are designed to be incredibly durable, you dont have to worry about spillage. The bucket elevator is designed to remain upright and can prevent material damages.
No matter your project or your transportation needs, most bucket elevators can operate in almost all types of weather. This means that your products wont get stalled out or halted by inclement weather. As you know, being unable to complete a job can cost you time, money, and energy.
Buckets can come in many shapes and sizes depending on the overall needs. On top of this, many bucket elevators are designed to have a much smaller footprint compared to more traditional conveying methods. This saves a good deal of energy consumption and also saves on some much-needed factory or plant floor space. Commonly, bucket elevators are able to be customized to specific needs and project requirements. On top of this, bucket elevators can be crafted with a wide variety of materials, including stainless steel, carbon steel, and more.
Many industrial plants and manufacturing facilities constantly have to review theirexpenses and overheadto ensure that projects are staying on schedule and arent going wildly over their costs. Of course, this also builds off of some of the other advantages of the bucket elevator. Since its a weather-resistant system that can handle large capacities more effectively, its a great way to manage projects more smoothly. Bucket elevators are also incredibly helpful for streamlining operations which is also a major money-saver for businesses.
Many industrial and manufacturing businesses rely on bucket elevators to handle a large number of their transportation needs. As long as the machinery is properly maintained and regularly cleaned, the system can last for quite a while which makes it an excellent investment for facilities. You can find bucket elevators at competitive prices, and youd be surprised just how effective they truly are.
This table is provided as a general reference only and does not mean all products will properly discharge over the entire speed range. Confirm all specifications based on your materials at time of order.
For general reference only. Confirm capacites at time of order as capacities may vary. Figures are based on 70 bushels per square inch with corn, soybeans and wheat and spouting at 40 degrees or greater. Wet corn should be spouted at no less than 45 degrees and capacities do not apply.
The hopper picks up the material from the underlying storage, and as the conveyor belt is lifted to the top, it rolls over the top wheel and then flips down. The bucket elevator pours the material into the receiving tank. The drive belt of the belt bucket elevator with belt drive is generally equipped with rubber belt, which is mounted on the lower or upper drive roller and the upper and lower redirection rollers. Belt bucket elevator: suitable for lifting from low place to high place. The supply material is automatically transported upwards and continuously after the material is put into the hopper through the vibrating table.
The standard configuration adopts the orthogonal shaft reducer and the fluid coupling, and is equipped with a backstop device. The transmission structure is compact and the flexible transmission is realized. It can not only stabilize the operation, but also protect the motor, reducer and traction parts.
Here are mainly steel buckets and high molecular polyethylene buckets, as well as shallow buckets, deep buckets, guide buckets, combination buckets, dewatering buckets, etc., which can be selected according to material characteristics and unloading methods. The bucket elevator can be equipped with a tear-resistant steel cord conveyor belt as the traction member, which has good toughness and high strength.

Adding a bucket elevator to your warehouse is an excellent way to boost productivity and cut down on injury potential with your employees. However, selecting a bucket elevator is not a one-size-fits-all approach. There are a number of options available, so you need to determine whichbucket elevator designstyle is right for your company needs. By going through the following steps youll identify crucial variants within your design process. This way, youll be able to better select abucket elevator designperfect for your business.
When you are considering abucket elevator designyou need to look at the different build methods and what you are doing to use the elevator for within your place of business. All of this will play a role in the eventual final design of your elevator.
From here, youll need to look at the overall makeup of the material youre using the elevator for. What is the overall weight of the material? Can you alter the weight or is it one, large object, so the weight will remain constant? Is there any moisture involved with the material, or is there a texture that might need a slick hoisting material on the elevator to make sure it doesnt slip off? The more you know about the material(s) youll be using the elevator for the easier it will be to design an appropriate device.
Next, youll want to consider how fast the elevator needs to move or how often youll be using it. And beyond the materials being moved, what about the space around the elevator? What kind of warehouse footprint are you looking at remaining in? Does it need to fit inside a small six-foot by six-foot square space? Or is there a bit more wiggle room? You dont want to order a bucket elevator and then discover it is not going to fit.
Lastly, is the operating going to be continuous, or will it only be used a few times during the day? Will it be used inside of a building with controlled temperatures, or does it need to go outside for exterior work where the weather elements are not as easily controlled?
Now that youve considered what youre going to be using the bucket elevator for, what youll be putting on the elevator and where youll be using the elevator, you need to consider the make of the elevator itself.
First, how tall and wide do you need it to be? Do you need to lift the materials up an additional ten feet? Or maybe you need the elevator to lift higher? Perhaps you have rafters above the regular work floor that is used to house excess gear and it is important to be able to lift the stored items up to these rafters. Youll need to know these measurements as it will help with the design.
Do you want the elevator to be open, fully sealed (so it feels more like a traditional elevator), or should it be just partially enclosed? Does there need to be some kind of airflow, or will the fully enclosed design be okay? There are some materials you dont want to fully enclose as it needs air ventilation.
It is okay if you do not know all of these specifics right away. Sometimes you might not fully know what kind of drive system will work best or how fast you need the elevator to rise and decline. The staff at Gough Econ, Inc. can help walk you through the design process. They will know how to best determine the kind of equipment and elevator specifics you need.
There are a number of configuration and movement variants youll need to consider. Elevators do not simply move directly up and directly down. You may want the elevator to move along an incline and down along a decline. Perhaps it is designed to work along stairs and there is a set incline it needs to follow. You may need the elevator to work along a stair step design. This is a design possibility, or you might need the elevator to travel along a floor and then lower down to the basement or a lower level. With a bucket elevator you are not required to have a simple up and down movement. After all, sometimes you need your bucket elevator to move in more than just a 90-degree angle.
With these configuration variants you can work with Gough Econ, Inc in determining these variations. As long as you do this youll be able to properly customize your elevator in order to bet improve productivity and safety within your production facility or warehouse.
Of course, if youre not fully sure on the configuration or shape of movement you will need dont worry. The sales engineers will work with you in going over your current facility blueprints and helping you decide where the elevators will work best.
By following these steps youll have a better understanding of how to find the rightbucket elevator designfor your business. However, you may still have questions. If you do, or if you are ready to place a bucket elevator order, a sales engineer is on hand at Gough Econ, Inc. to assist. Whatever assistance you might need, you can email or call Gough Econ at your convenience. So, if youre ready to take the next step in your warehouse or manufacturing plant production, yourbucket elevator designis just a single email or phone call away.
