Bucket elevators for grain

BUCKET ELEVATORS by KMZ INDUSTRIES

A grain bucket elevator is essential equipment for a grain storage complex, designed to vertically transport bulk materials. You can purchase a bucket elevator in Ukraine from KMZ Industries, whether for a newly constructed grain storage complex or an existing one. But why choose KMZ Industries? Let’s take a closer look at our products.

What Types of Grain Bucket Elevators Does KMZ Industries Manufacture?

KMZ Industries produces two types of bucket elevators: standard and self-supporting (with maintenance platforms installed next to structures). Their main difference lies in their design:

• Standard bucket elevators are installed in a bucket elevator support tower. This requires the construction of an additional metal frame, where the bucket elevator, service ladders, and other components are mounted.
• Self-supporting bucket elevators have a casing that can bear operational loads. They come equipped with ladders and platforms for inspection, maintenance, and rest. They can be installed independently without bucket elevator support towers but are secured to surrounding structures (such as silos or grain dryers) for stability.

This solution is more cost-effective compared to an elevator in a tower. However, operating a self-supporting bucket elevator is more complex. Additionally, this design is only cost-efficient when installing one or two bucket elevators. If more than two are needed, the standard tower-mounted option is more advantageous.

KMZ Industries’ bucket elevators consist of boot and head sections, drive unit, discharge spout, sealed ducts, belt and buckets. The belt speed ranges from 2.5 to 2.7 m/s.

Additionally, our bucket elevators are equipped with:

• Rotation speed sensors, belt misalignment sensors, and blockage sensors to ensure full control over the equipment’s operation.
• Aspiration system connections to separate dust from the grain, keeping the grain storage complex cleaner and reducing the risk of dust ignition or explosion.
• Explosion relief valve to control sudden pressure spikes, enhancing operational safety.

A key feature of our bucket elevators is their grain-friendly operation. This is achieved through the optimized geometry of the head section, which minimizes the impact of grain mass movement. The upper wall of the head smoothly redirects the grain flow, reducing kinetic energy. In the standard configuration, the head is lined with reinforced polyurethane, a highly wear-resistant material.

Our latest high-tech elevator head design also results in significantly smaller dimensions and reduced weight, making installation and operation easier.

The new-generation bucket elevator belt is stitched using locks, which provides the following advantages:

• Reduced distance between buckets and the flipper
• Elimination of product backflow
• No need to trim buckets at belt joints

Bucket Elevator Heads and Boot Sections

• The lower part of the bucket elevator head features inspection hatches, allowing easy access to adjust the gap between the flipper and the buckets to minimize product backflow.
• The head includes a frame for mounting onto the support structure, speeding up installation and eliminating additional costs for custom metal structures.
• The shaft is attached to the drum using split tapered bushings, following the Taper Bush principle, simplifying drum assembly and disassembly.
• The boot section includes a slide gate on bearings (bolt-free design) for quick and easy cleaning.

For bucket elevator components, we collaborate with the French company STIF. Their JET buckets feature a patented shape, ensuring improved product discharge and increasing elevator productivity compared to competitors’ models.

Metal buckets have curved edges, reducing grain damage and lowering the breakage percentage. Their optimized geometry promotes uniform wear (eliminating stress concentration points) and minimizes product adhesion inside the bucket.

Technical Specifications of KMZ Industries’ Grain Bucket Elevators

• Made from European galvanized steel (S350GD) with a zinc coating of 275 g/m²
• Working height: up to 60 meters
• Grain is discharged at a natural angle of repose, minimizing damage
• The boot drum is designed as a squirrel cage, preventing grain buildup and ensuring long-term efficiency
• European bearing units for reliable, long-lasting operation
• The head section is lined with reinforced polyurethane as standard
• Fine-tuning of the drive drum shaft bearing in two axes reduces the risk of belt misalignment
• Compact and highly reliable conical-cylindrical drives from top European manufacturers
• Inductive belt misalignment sensors from STIF — no moving parts that can break, eliminating false triggers
