Bucket Elevator Systems
An enclosed vertical handling system that lifts grain, powder and granular products from floor level to the line above, built to project with food-grade buckets and belts.
Bucket Elevator
A bucket elevator moves grain, powder and granular products vertically, lifting material from floor level to the higher feed points of a production line. Kasas Teknoloji manufactures bucket elevator units for food and packaging plants, sizing the casing height, bucket volume and inlet positions around the existing layout of each facility. The casing is produced in stainless steel or painted carbon steel, while buckets and belts in contact with the product are specified in food-grade materials for hygienic handling. Compared with long inclined conveyors, the enclosed vertical design occupies a small footprint and keeps the line flow uninterrupted. Capacity, lift height and product characteristics are evaluated together, and each unit is engineered for its own plant. Ice packaging lines feeding vertical baggers use dedicated bucket arrangements.

A bucket elevator is built around an endless belt or chain carrying buckets at fixed intervals. Product enters through the inlet at the boot section, where the rising buckets scoop it up and carry it inside the enclosed casing. At the head section the drive pulley turns the buckets over and directs the product toward the discharge spout. The discharge method follows the behaviour of the material: free-flowing grain is thrown out centrifugally at higher speed, while fragile or sticky products are discharged more gently at reduced speed. Chain-driven designs suit heavier and more abrasive materials, whereas belt-driven designs run quieter and with less vibration. A take-up assembly in the boot maintains belt or chain tension so that slipping and bucket misalignment are avoided. Because the return run is enclosed, dust escape is limited and product loss inside the plant is reduced. Inspection doors allow buckets and belts to be replaced without dismantling the casing.

Frequently Asked Questions
What is a bucket elevator?
A bucket elevator is an enclosed handling system used to move grain, powder and granular products vertically. Buckets fixed at regular intervals on an endless belt or chain collect material at the lower inlet and release it at the upper discharge spout. It occupies far less floor space than an inclined conveyor and covers the height difference inside a plant efficiently.
How does a bucket elevator work?
Material enters the boot section at the bottom of the casing and is picked up by the passing buckets. The buckets travel upward inside the enclosed casing and, as they turn over at the head section, release the product into the discharge spout. Free-flowing products are discharged centrifugally, while delicate products are handled at lower speed. Empty buckets return down the enclosed run.
Which products can a bucket elevator handle?
Most dry granular, powdered and free-flowing materials can be handled. Typical duties include cereals and grain, pulses, sugar, flour, nuts, granular plastics and ice. Particle size, moisture content, flowability and abrasiveness all affect bucket type, bucket spacing and belt speed, so these properties are reviewed together during the design stage of each project.
How is bucket material selected?
Bucket selection follows the properties of the conveyed material. Food-grade plastic or stainless steel buckets are used for food products, while thicker metal buckets suit abrasive and heavy materials. Bucket depth and lip profile are chosen according to how freely the product flows. Wide-mouth profiles that ease discharge are preferred for moist or sticky products.
How are lift height and capacity determined?
Lift height is taken from the difference between the pick-up level and the inlet level of the machine being fed. Capacity is calculated from the hourly product requirement, the bulk density of the material and the daily running time of the line. Kasas Teknoloji reviews this data together with the plant layout, then engineers, installs and commissions the unit.
