Aggregate Conveying Bucket Elevator

What is Aggregate Conveying Bucket Elevator?

Aggregate conveying bucket elevator  is a mechanical equipment specially used for vertical conveying of aggregates such as sand, gravel, machine-made sand, slag, etc. It is widely used in industries such as construction, building materials, mining and concrete mixing plants. It lifts aggregates from low to high places through a bucket fixed on a belt or chain, and is suitable for processes such as crushing, screening, storage or loading.

What are the advantages of Aggregate Conveying Bucket Elevator?

Aggregate Conveying Bucket Elevator can vertically transport aggregates of various sizes, is sealed and dustproof, and has large output. The following are the specific advantages:

Large-capacity vertical conveying: The lifting height of a single machine can reach 60 meters (special design can reach 80 meters), the conveying capacity is 800 tons/hour, and the vertical conveying efficiency is more than 30% higher than that of the inclined belt conveyor.

Conveying a variety of aggregates: It can handle aggregates of various particle sizes from 0 to 50 mm, suitable for crushed stone (Mohs hardness ≤8), machine-made sand, recycled aggregates, etc. The special design can convey wet materials with a moisture content of ≤8%

Space saving: The floor area is only 1/3 of the belt conveyor, and it can be flexibly arranged in a narrow space. Vertical conveying reduces the horizontal conveying link

Durability: It uses high-strength materials to adapt to harsh working environments.

Aggregate Conveying Bucket Elevator Principle

Aggregate Conveying Bucket Elevator drives the lifting belt through the motor, drives the loading bucket to lift the Aggregate from a low place to a high place, and uses gravity and friction to achieve material transportation.

What are the structural components of Aggregate Conveying Bucket Elevator?

Aggregate Conveying Bucket Elevator consists of a lifting bucket, a transmission device, a frame, a drive system, etc.

Lifting bucket: used to load and lift materials.

Lifting belt: connects the bucket and the motor to transmit power.

Frame: supports the entire elevator structure.

Drive system: motor and reducer, providing lifting power.

How to select Aggregate Conveying Bucket Elevator?

Analysis of aggregate characteristics

The particle size, humidity, hardness and abrasiveness of aggregate directly affect the equipment selection:

Parameters	Influence of selection	Solution
Particle size	Large aggregate (>50mm) is prone to jamming or impact wear	Use deep bucket/sawtooth bucket, chain drive (impact resistant)
Moisture	Wet materials are easy to adhere, resulting in incomplete discharge	Choose a stainless steel hopper or anti-stick coating
Hardness	High-hardness aggregates (such as granite) accelerate wear	Use wear-resistant steel hoppers or replaceable liners
Clay content	Easy to agglomerate and block the hopper	Enlarge the discharge port and add a vibration cleaning device

Lifting capacity

Calculation formula of Aggregate Conveying Bucket Elevator: Lifting capacity (t/h) = single bucket volume (L) × bucket distance (m) × lifting speed (m/s) × filling rate (usually 70-90%)

Small output (<50t/h): light belt bucket elevator (such as NE series).

Medium output (50-300t/h): medium chain bucket elevator (such as TH series).

Large output (>300t/h): heavy plate chain bucket elevator (such as TD series).

Lifting height

Below 10m: suitable for short-distance lifting (such as concrete mixing plant).

10-30m: common in sand and gravel aggregate production lines, the structural rigidity needs to be strengthened.

Above 30m: Special design is required (such as dual drive, reinforced chain/belt).

Note: The higher the lifting height, the greater the power requirement, and the tensile strength of the chain/belt needs to be checked.

Bucket Material

Material	Applicable scenarios	Advantages and disadvantages
Carbon steel (Q235)	Dry, low-wear aggregate (such as ordinary sand and gravel)	Low cost, but poor wear resistance
Wear-resistant steel (NM360)	High wear aggregate (such as granite, iron ore)	Long life, but high price
Stainless steel (304/316)	Wet or corrosive environment (such as sea sand, recycled aggregate)	Rust-proof, but high cost and average wear resistance
Rubber-lined	Reduce noise and impact (such as glass aggregate)	Shockproof, but poor high temperature resistance

Drive System

Type	Applicable scenarios	Features
Belt drive	Small and medium-sized hoists (<50m), light to medium-loaded aggregates	Smooth operation, low noise, but easy to slip
Chain drive	Medium and large hoists (>30m), heavy loads or large aggregates	Impact resistant, but requires regular lubrication and maintenance
Dual drive	Ultra-high lifting (>50m) or ultra-large capacity (>500t/h)	Even power distribution, reducing the risk of single point failure

Other key selection factors

Sealing: Aggregates are prone to dust, requiring a fully enclosed housing + dust removal interface (such as a pulse dust collector).

Discharging method: Centrifugal discharging(suitable for small particles and high-speed lifting ,such as sand);  Gravity discharging: (suitable for large aggregates (such as crushed stone) and low-speed operation).

Safety device: Anti-reversal device (to prevent aggregate backflow during shutdown), Deviation alarm, overload protection.
