Grain grading machine can be categorized into various types based on their working principles and applicable scenarios, primarily including the following:
Length grader: This type of equipment separates grains based on their length differences, commonly used in rice processing to distinguish between whole rice and broken rice.
Nest-eye roller selection machine: This type of equipment utilizes the structure of a nest-eye roller to grade and sort materials based on the length and shape characteristics of grain particles. It is suitable for granular and freely flowing materials.
Thickness classifier: It classifies materials based on their thickness dimensions, effectively separating immature grains and broken materials.
Weight sorter: This type of equipment grades grains based on their weight or gram weight, and is widely used for automated sorting of agricultural products such as corn, potatoes, and sweet potatoes.
Size sorter: It grades materials based on their size or dimensions, commonly used for sorting materials such as corn, onions, and fruits.
Mesh belt conveyor sorter: Combining conveyor belt and sorting functions, it is suitable for continuous conveying and sorting of materials such as grain, fruits, and vegetables, and is commonly used in production lines.
Belt-type logistics sorting machine: Primarily used for the loading and unloading of grain as well as automated conveying and sorting in logistics processes, emphasizing its application in logistics scenarios.
These types are not completely mutually exclusive, and they are often used in combination according to specific needs in practical applications.
