With outstanding quality, high conveying capacity, reliable operation, long service life, and low operating costs, AGICO Cement bucket elevators help customers worldwide handle bulk materials. We offer bucket elevators for a wide range of lime materials. Simply tell us your material temperature, particle size, dust characteristics, abrasiveness, and required throughput, and our engineers will recommend a suitable elevator type and tailor its design to your needs.
Belt Bucket Elevator vs. Chain Bucket Elevator
AGICO Cement offers two types of bucket elevator for lime plant. One is belt bucket elevator, the other is chain bucket elevator. The final choice depends on material temperature, lump size, bulk density, abrasiveness, moisture, required capacity and lifting height. No matter belt bucket elevator or chain bucket elevator, the final specifications are determined according to the actual material and plant layout.

Bucket Elevator Main Components and Custom Options
A bucket elevator for a lime plant must be designed around the material being handled and the conditions at the installation point. Crushed limestone, hot quicklime, quicklime powder and hydrated lime have different effects on the casing, buckets and traction components. For this reason, the elevator configuration should be selected only after the material temperature, particle size, bulk density, abrasiveness, moisture condition, lifting height and required capacity have been confirmed.
AGICO can adapt the following components to suit new lime production lines as well as existing plant upgrades.
Elevator Casing
Carbon steel casing provides a strong, enclosed conveying channel. Plate thickness, reinforcement, sealing and surface treatment can be customized for outdoor, dusty, humid or high-temperature conditions. Sealed inspection doors allow convenient maintenance while helping control lime dust leakage.
Steel Buckets and Wear-Resistant Lips
Bucket size, profile and spacing are selected according to the material and required capacity. Reinforced steel buckets and replaceable wear-resistant lips are available for coarse limestone, quicklime lumps and other abrasive materials.
Belt or Chain System
Belt bucket elevators are generally suitable for fine, free-flowing materials at controlled temperatures. Heat-resistant belts can be selected for elevated-temperature service.
Heavy-duty chain elevators are better suited to hot, coarse or highly abrasive materials. The chain specification is determined by the lifting height, bucket load and operating conditions.
Replaceable Wear Liners
Replaceable liners can be installed at the inlet, boot and discharge sections. They protect the main structure from impact and abrasion while reducing long-term maintenance costs.
Dust Collection Connections
Dust extraction connections can be installed at major transfer points. Their location and size are coordinated with the plant’s dust collector to reduce dust leakage during material loading and discharge.
Safety Monitoring System
Available monitoring devices include speed switches, belt or chain misalignment detectors and boot-level sensors. These devices provide early warnings and can stop upstream feeding when abnormal operation or material blockage is detected.
Custom Options
Optional configurations include a backstop, access platforms, maintenance doors, customized inlet and discharge chutes, special surface treatment and project-specific control devices.
Customized for Each Lime-Handling Duty
Not every project requires every option. AGICO configures the bucket elevator according to the conveyed material, particle size, bulk density, temperature, capacity, lifting height and connection with upstream and downstream equipment in the lime production line.
Materials Our Lime Bucket Elevators Can Handle
| Material | Typical Form | Main Handling Concern | Recommended Design Direction |
|---|---|---|---|
| Limestone | Crushed lumps | Impact and abrasion | Heavy-duty buckets and wear-resistant inlet |
| Limestone powder | Fine powder | Dust leakage | Enclosed casing and dust extraction |
| Quicklime | Lumps or powder | Heat, abrasion and moisture sensitivity | Heat-resistant components and sealed casing |
| Hydrated lime | Fine powder | Dust, aeration and buildup | Dust-tight, low-spillage design |
| Dolomite | Lumps or powder | Abrasion and variable density | Project-specific bucket and drive selection |
| Calcined dolomite | Hot lumps | Elevated temperature and wear | Heavy-duty chain-type arrangement |

Customize your bucket elevator
Please provide the material name, particle-size range, bulk density, moisture content, normal and maximum temperature, required throughput, lifting height and operating hours. Information about the upstream and downstream equipment is also important.
Why Lime Materials Require Special Elevator Design
If you work in the lime production industry, a customized bucket elevator is usually required for the following reasons:
High Temperature: Quicklime discharged from the kiln may still be at an elevated temperature.
Abrasive Particles: Limestone and quicklime can cause wear to the buckets, chains and inlet section.
Fine Dust: Hydrated lime and lime powder can generate significant dust during conveying.
Moisture Sensitivity: Quicklime reacts with water, while hydrated lime may absorb moisture and form lumps.
Material Buildup: Fine powder may accumulate in the boot section, buckets and discharge chute.
Unstable Feeding: Sudden surges from upstream equipment may cause material buildup in the boot section or overload the drive motor.
Frequently Asked Questions
Not necessarily. These materials have different particle sizes, temperatures, flow characteristics and wear levels. The elevator must be selected for the specific material and operating conditions. A machine designed for limestone lumps may not be suitable for fine hydrated lime powder without modification.
Belt bucket elevators are generally suitable for fine, free-flowing materials at controlled temperatures. Chain bucket elevators are usually preferred for hot, coarse or highly abrasive materials. The final selection depends on the material, capacity, lifting height and operating temperature.
Yes, provided that the elevator is designed for the actual quicklime temperature. A heat-resistant belt may be suitable within its approved temperature range, while hotter or more demanding applications may require a heavy-duty chain elevator. Normal and maximum temperatures should both be provided during selection.
Dust leakage can be reduced through an enclosed casing, sealed inspection doors, properly designed inlet and discharge chutes, and dust collection connections at transfer points. The elevator should be coordinated with the plant’s ventilation and dust collection system.
Please provide the material name, particle-size range, bulk density, moisture content, normal and maximum temperature, required throughput, lifting height and operating hours. Information about the upstream and downstream equipment is also important.
