The ball shaping machine is a piece of equipment designed for the secondary shaping and polishing of various granules, including organic fertilizers, compound fertilizers, and bio-organic fertilizers. It primarily performs finishing work on semi-finished granules produced via extrusion or disc granulation processes; through high-speed centrifugal rotation and friction, the sharp edges of the granules are smoothed away, resulting in spherical finished products characterized by uniform size, smooth surfaces, and high sphericity. The granulation yield exceeds 95%, with some high-end models achieving a spheronization rate of up to 98%.

As a key component in the post-processing stage of fertilizer production lines, the ball shaping machine is widely used in organic and compound fertilizer plants, feed mills, and agricultural solid waste resource utilization projects. It is capable of processing organic fertilizer granules made primarily from livestock and poultry manure (such as chicken or cattle manure), as well as bio-organic and oil-cake fertilizer granules derived from materials like plant ash, lignite, crop stalks, and soybean cake.

What is the working principle of the ball shaping machine?

The working principle of the ball shaping machine relies on the combined action of centrifugal force and friction. The main motor drives a large wheel via a pulley and belt; this wheel is fixed to the main shaft and, through a coupling, drives the spheronization disc to rotate at high speed. Once cylindrical or oblate semi-finished granules enter the disc, they move rapidly across its surface under the influence of centrifugal force, undergoing continuous collisions and friction——both among the granules themselves and against the inner wall of the spheronization chamber.

The spheronization chamber remains stationary, while the material inside moves in a twisting, reciprocating pattern along the edge of the disc and the chamber wall, driven by centrifugal force. During this process, the sharp edges of the granules are gradually worn smooth, and the particles tend to assume a spherical shape. The equipment is typically equipped with a spraying system; the addition of an appropriate amount of moisture helps the material bind evenly and improves the spheronization outcome.

In multi-stage ball shaping machines (dual- or triple-stage), the material automatically transfers to the next spheronization disc after the first stage; following multiple stages of processing, the finished product is discharged through the outlet. The process involves continuous feeding and discharging, enabling automated batch production.

What are the applications of the ball shaping machine?

The ball shaping machine is primarily used in the following scenarios:

Organic fertilizer production: It is used for the spheronization and shaping of organic fertilizer granules made from raw materials such as livestock and poultry manure, crop straw, and spent mushroom substrate; it serves as an indispensable piece of finishing equipment in organic fertilizer production lines.

Compound and blended fertilizer production: Used in conjunction with disc granulators or extrusion granulators, it performs secondary polishing and shaping on compound and blended fertilizer granules, ensuring uniform nutrient distribution and high-quality granule appearance.

Feed processing: It processes various types of feed granules to improve their flowability and palatability.

Bio-organic and specialty fertilizers: It is used for the precision shaping of bio-organic fertilizer granules and oil-cake fertilizer granules.

Within the production line, the ball shaping machine is typically installed downstream of the granulation equipment and upstream of the drying and cooling equipment, ensuring seamless integration without the need for additional material transfer.
