Disc ball forming machine

The granulation disc of the disc ball forming machine adopts an integral circular arc structure, and the granulation rate can reach over 93%. The granulation disc is equipped with three discharge ports, which facilitate intermittent production operations, greatly reducing labor intensity and improving labor efficiency. The reducer and motor are driven by flexible belts, which ensures smooth starting, reduces impact force, and improves equipment service life. The bottom of the granulation disc is reinforced with multiple radiating steel plates, which are sturdy, durable, and not easily deformed. Thickened, weighted, and sturdy base design, no need for anchor bolts to fix, smooth operation.

Structure of disc ball forming machine

The disc ball forming machine consists of a large plate, large gears, transmission parts, frame, base, scraper frame, and unpowered scraper.

1. The main body of the disc ball forming machine includes a frame, an adjusting part, and a granulation disc structure;

2. One main reducer, with a pulley installed on the input shaft and a small gear installed on the output shaft;

3. One main point motor, equipped with one pulley;

4. Support granulation disc device, including one main shaft, two sets of roller bearings, and two bearing seats;

Performance characteristics of disc ball forming machine

1. The disc ball forming machine has a novel and reasonable structure, with reduced weight and height. The process layout is flexible and convenient, suitable for the renovation of old factories.

2. The market tilt angle can be adjusted. Using angle washers for flexible and convenient adjustment.

3. Adopting high-quality non powered combination scraper integration reduces auxiliary power consumption.

4. The market is composed of a market body and market segments. Reduce the power of the main motor. The disc joint can be adjusted up and down along the disc body. The end of the disc is a flange, which ensures that the material ball is not pulled or torn when it is released from the disc.

5. Dredging design, using a non powered combination scraper to clean the edges and bottom, a corner cleaning scraper to clear the corners, and special treatment technology for the disc body. The dredging and ball forming effect is good, and there will be no large mud lumps. 90% of the ball diameter is between 3-5mm.

Working principle of disc ball forming machine

Pre added water to form a spherical disc full disc ball method. The raw material powder is uniformly wetted by atomized water in a dual axis mixer, forming a ball core with very uniform particle size, and then sent into a ball forming disc for ball forming. The moisture content of the material ball should be controlled at 12-14%. Most of the water should be added to the double axis mixer, and only a small amount of supplementary water should be added to the ball forming plate, with the supplementary water amount controlled at around 0-3%. Dry powder granulation is directly added to the ball forming disc and sprayed with an appropriate amount of water. After entering the ball forming disc, the raw material core is subjected to centrifugal force, frictional force, and gravity in the disc, and moves along a parabolic path.

Due to the adhesive and plastic properties of the material, the ball cores adhere to each other and gradually grow during movement. When the inclination angle of the ball disc, the height of the disc edge, the rotation speed, and the moisture content are constant, the material balls of different particle sizes roll downward from the disc edge at different detachment angles due to different gravity. During the continuous rolling process of the material ball, the moisture inside the ball is constantly expelled from the surface. Due to the adhesive properties of the material and the natural evaporation of the surface liquid film, the material ball has a certain strength, and then it is discharged from the edge of the inclined disc as it rotates.
