Comments Off on What Is Rice Mill Bucket Elevator: Types and Functions

In rice milling, precision as well as productivity are essential. The rice mill bucket elevator is one of the most important equipment in this procedure. This innovative mechanism is essential for the vertical movement of both raw and processed rice grains throughout the milling plant.

In this blog, we will explore the types, uses, and functionality of rice mill bucket elevators as we understand their complexity.

Understanding Rice Mill Bucket Elevators

A rice mill bucket elevator is a vertical conveying device used in rice milling industries. It is used to lift and move rice grains between stages of processing. The bucket elevator comprises several buckets attached to a belt and moves vertically along a pulling mechanism or guide rail.

The buckets are made to collect and transport rice grains in an upward or downward motion. This enables effective material handling and transportation.

Functionality of Rice Bucket Elevator

Simplifying the flow of rice grains during the milling process is the main purpose of a bucket elevator. It moves unprocessed rice from the cleaning and husking phase to the de-stoning, polishing, and grading steps. It also makes it easier to move milled rice to the next step, guaranteeing an uninterrupted flow of grains without human involvement.

Types of Rice Mill Bucket Elevators

1. Centrifugal Discharge Bucket Elevators

The most popular bucket elevators used in rice milling facilities are those with centrifugal discharge. The buckets in this arrangement are separated and fixed on a belt to release the rice grains when they hit the head pulley by centrifugal force. With its high throughput rates, this elevator is ideal for handling materials that flow freely, such as rice grains.

2. Continuous Discharge Bucket Elevators

The closely spaced buckets that form a continuous loop around several pulleys are the defining feature of continuous discharge bucket elevators. Continuous discharge elevators don’t use centrifugal force to release the material, as used by centrifugal discharge elevators.

The rice grains are released by mechanical scooping devices or gravity. This elevator is perfect for handling delicate or non-free-flowing products with little spillage.

3. Positive Discharge Bucket Elevators

Bucket elevators with positive discharge are made to handle items that attach to the buckets. Customised buckets with curved bottoms are present to guarantee full material discharge at the discharge point. In rice milling plants that process sticky rice varieties, positive discharge elevators are frequently utilised.

Applications and Considerations

From the processing of raw paddy to the packaging of polished rice ready for consumption, rice mill bucket elevators are essential in every stage of the rice milling process.

For a rice milling business, selecting the best bucket elevator requires careful consideration of several important factors. First and foremost, a detailed evaluation is needed of the milling facility’s working circumstances.

Conditions like temperature, relative humidity, and dust exposure can affect how well the bucket elevator works and how long it lasts. Choosing a bucket elevator that is made to endure the unique environmental demands of the milling plant guarantees continuous operation and less maintenance downtime.

Factors including throughput rates, batch sizes, and peak production demands are necessary so that the bucket elevator can handle the required amount of rice grains without overloading the system or compromising efficiency.


Rice mill bucket elevators are essential for the effective handling and movement of rice grains within a milling facility. Bucket elevators facilitate the smooth functioning of rice milling operations by effortlessly and precisely conveying bulk materials vertically leading to production and throughput.

Rice millers can optimize overall efficiency and performance by integrating this equipment into their rice milling processing with knowledge of the types and functions of bucket elevators.
