Corn Gravity Separator Factory

Corn Gravity Separator

Shijiazhuang xinlu technology co.,ltd offers the Corn Gravity Separator, engineered to handle the larger kernel size and variable density characteristics of maize. The unit is intended for seed producers, processors preparing corn for seed treatment, and facilities seeking to reduce broken- kernel carryover and increase seed lot uniformity.

Working principle

The Corn Gravity Separator employs density stratification across a vibrating, grooved deck while a controlled upward airflow interacts with the seed bed. Heavy, whole kernels migrate toward the clean outlet, and lighter material-broken kernels, pericarp fragments, immature kernels and dust- are drawn off. Adjustments to deck slope, vibration stroke, and airflow allow the separator to be tuned for different maize hybrids and moisture conditions.

Key components

.Large-format vibrating deck with robust, replaceable mats suitable for coarse kernels

·Heavy-duty vibratory drive providing broad stroke and frequency ranges

·High-capacity aspirator/blower with variable speed control and adjustable manifold for even airflow distribution

. Feed hopper and distribution system sized for high throughput

·Dust collection and reject handling chutes; control interface for operator adjustments 

Performance and applications

Capacities vary with kernel size and desired purity; smaller units may process in the order of 5-10 t/h while larger decks can handle 20-30 t/h or more. The Corn Gravity Separator is commonly used as a final polishing stage before seed treatment or packaging, and as a preparatory stage to protect optical sorters and coaters from fines and broken pieces.

Operation and adjustment

Operators tune the deck tilt and stroke to balance cleaning intensity against kernel breakage.

Because maize kernels are more robust, stroke amplitudes can be set higher than for delicate seeds, but care is required to avoid excessive mechanical impact. Airflow is adjusted to account for humidity and the proportion of light material; in damp seasons, lower airflow with slightly higher stroke often yields better separation.

Maintenance and service

Maintenance emphasizes inspection of wear on deck mats and bearings, regular cleaning of aspirator ducts and filters, and periodic balancing of the vibration drive. Shijiazhuang xinlu technology co.,ltd provides maintenance manuals, spare parts, and training to help operators perform preventive checks and to reduce unplanned downtime.

Customization

Custom deck mat patterns, wider deck options for greater throughput, and integrated reject conveyors are available. The unit can be supplied as a freestanding module or with quick-connect interfaces to feed hoppers and bagging equipment.
