bucket elevator basics
If material needs to be moved vertically, chances are a bucket elevator is the ideal solution for the job. In fact, the versatility and configurability of this equipment make bucket elevators a common bulk material handling system in a number of different industries. Listed below are basic facts that highlight why bucket elevators are commonly used, with key elements to consider when choosing whether or not this equipment is the right material handling solution for a particular application.
In simple terms, bucket elevators vertically convey bulk materials. They are considered similar to conveyor belts, with the greatest difference being that bucket elevators move material using buckets attached to a rotating belt or chain. The buckets work to pick up material, move it to the desired endpoint, discharge material, and finally return to the starting point to pick up a new load.
Bucket elevator configurations are engineered based on the application, material, required horsepower, and elevator height. Configuration options include centrifugal bucket elevators and continuous bucket elevators, with both models including belt and chain options.
A centrifugal bucket elevator employs centrifugal force to throw material out of the buckets as they travel over the head pulley or sprocket. This type of bucket elevator operates at a higher speed and spaces buckets further apart versus continuous bucket elevators. The result of the high speed and bucket spacing is optimized material fill and reduced interference between buckets.
Continuous bucket elevators operate at a low speed with closely spaced buckets compared to centrifugal bucket elevators. This action permits material flow over the backside of the preceding bucket. Additionally, extended sides on the buckets gently guide material into the discharge spout. These modifications create an ideal environment for fragile, abrasive, and sluggish materials. Benefits include limited material aeration, minimized breakage of friable material, and minimized product damage of fragile material.
In addition to varying configuration options, there are also a number of bucket options available, with material and elevator design being primary bucket selection criteria. Other bucket elevator features include removable top covers, access doors for easy maintenance, and horizontally and vertically heavy-reinforced, jig welded head, boot, and intermediate sections.
Bucket elevators can handle a wide range of free flowing materials with varying characteristics. Light, fragile, heavy, and abrasive materials can all be transferred using a bucket elevator. Examples of materials conveyed via bucket elevator include:
Bucket elevators are not recommended for use with material that is wet, sticky, or has a sludge consistency. These types of materials tend to create discharge issues, with build-up being a common problem.

bucket elevator design considerations
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.

harmfulness of overload of bucket elevator
Bucket elevator is a normal lifting equipment for industry, food industry and mining industry , according to the traction type,the bucket elevator can be divided into the belt bucket elevator and chain bucket conveyor, bucket elevator usually play a important part of the production line, its very important to normally work for a long time, to ensure that need to have the right the habits, in addition to a complete set of maintenance plan, and avoid all kinds of abnormal accidents, especially overload, overload is a huge potential risk to the elevator, once the accident happened, the elevator will be devastating damaged, this article will discuss the overload harm of belt bucket elevator.
1.Lifting belt damaged
For belt bucket elevator,if bucket elevator running overload,the lifting belt will be in excessive tension, the lifting belt itself has a tensile strength, tension overloading caused force is larger than the maximum tensile strength, then the belt will be damaged, the belt will roundly fall off,the bucket elevator can not work.
2.Lifting belt slipping
Some customers in order to avoid overloading the accident, deliberately increases its own strength, in fact, this is not a reasonable method, even if the lifting belt does not occur breaking in case of overloading, but another accident will happened, that is slipping, this is because when overload occurs, the bucket with sufficient strength at this time, the lifting belt does not break, but will upgrade with the extension of the length, when the extended length is longer than tension travel distance,the tension device will fail, the belt will slipping, although it has not broken belt harm, but due to slippage,the speed of belt was reduced,then influence the capacity.
3.Pulley shaft broken
The probability shaft broken accident is not high, but the cost is very high with the broken shaft, the pulley shaft has itself breaking load, when the bucket elevator is overloaded, the lifting belt will produce a large tension force, when the tension force is larger than the maximum section breaking force of pulley shaft, the pulley shaft will be broken.
4.Bucket fall off
The bucket elevator belt is connected with the hopper with bolts, if there is much material in the bucket, connection bolts will suffer uneven force, then so bolts hole on the belt will become larger and larger, resulting in falling bolt and bucket.
The bucket elevator overload not only harmful to the mechanical part,but also harm to the motor,when bucket elevator overload,the motor also will be overload,the one current will cause ,motor heating,then lead to motor burn out.

12 common bucket elevator troubleshooting | m&c
As a kind of conveying equipment with simple structure, low maintenance cost and high conveying efficiency, bucket elevator is widely used in food, medical, chemical and mining industries, and plays an increasingly important role.
In the actual conveying operation, the efficiency of bucket elevator is affected by the problems of slipping, deviation, tearing, returning, low production and abnormal noise. In this article, we will tell 12 types of troubles and solutions of bucket elevator, to help you produce efficiently!
Reduce the amount of material feeding, and strive to feed evenly, if after reducing the amount of feeding, still can not improve skidding, it may be that too much material is accumulated in the machine or the hopper is stuck by foreign bodies.
1. When lifting different materials, the speed of bucket is different: when lifting dry powder and granule, the speed is about 1-2 m/s; when lifting bulk material, the speed is 0.4-0.6 m/s; when lifting wet powder and granule, the speed is 0.6~0.8m/s.
If the bucket runs too fast, the material will be unloaded ahead of time, resulting in material return. According to the lifting material, the speed of the bucket should be reduced appropriately to avoid material return.
The hopper is the bearing component of the hoist, which has higher requirements for its materials, so the materials with good strength should be selected as far as possible during installation. The general hopper is made of ordinary steel plate or galvanized sheet welded or stamped.
The solution is to increase the air outlet, that is, to set up the air outlet above the discharge pipe of the elevator head, and the outlet pipe leads directly to the atmosphere to reduce the dust concentration in the head so that it can not produce powder explosion.
bucket elevator - ideal conveyor for vertical conveying | m&c
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.
bucket elevator working principle/technical parameters,pictures, price, manufacturers - siehe industry
The machine is mainly applied for vertical elevating of power or granule materials. Multi buckets are installed on a circulation chain or belt. When working, the materials will be loaded into bucket from the bottom and then discharged when bucket moves to top. The buckets work continuously in circulation in a closed shell to realize continuous materials elevating. The machine is characterized in large elevating capacity, low energy consumption, low noise, good seal performance, no dust leakage, safe and reliable.
Driving power is small. Use in-flow type feeding, induction type discharging, hoppers with large loading capacity are intensively layout. so it has high energy efficiency because it is almost no materials go back or materials dug phenomenon.
Wide Application range
Wide range of application. This kind of elevator does not have many requirements of materials variety, materials property etc. It not only can elevate materials like general powders, granules, it is also can elevate materials with strong wearness. It has nice sealing and less environmental pollution.
Stable operation, lowfailurerate
Good reliability, advanced design principle and processing method ensure the reliability of the machine running. None failure time is more than 20000 hours. It runs stably so it is also suitable for lifting materials to higher places.
Long service life
Service life is long. The elevator feeding way is inflow type and no need to get the materials with the bucket. Little extrusion and collision among the parts. The machine is designed to ensure that material during feeding and discharging will be scattered little, which reduce the mechanical wear.
The recycling bucket of Bucket Elevator scoops the materials up from the storage bin, elevate to the top with the conveyor belt or chain, flip down after bypass the top wheel, and poured material into the receiving groove. Belt driving (The belt normally is rubber belt) of Bucket Elevator is installed at top and down transmission drum or the top and down idler drum . Chain driving (generally are two parallel transmission chain) is installed on the Bucket Elevator, at the top and down, there are a pair of drive sprocket. At down and top, there is a pair of idler sprocket. Normally the bucket elevator is with shell to prevent the dust inside the bucket and also dust generated during delivery.
