I.Basic Working Principle

By vacuum suction (or artificial feeding) into the conical container of the material through the mixing of the binder added in the modified stirrer under the action of the ring, radial, axial movement, fully mixed, and then by the granulation cutter cut into uniform texture, dense spherical particles. (The following schematic diagram)

III. Equipment Composition, Main Structure, and Materials

1. Composition

The machine is mainly composed of the chassis, covered container, mixing system, cutting system, discharge device, control system, and water-gas system. (As shown in the figure below)

 

IV. Main Structure and Materials

1. Chassis:Made of welded steel, the frame is covered with stainless steel plates. The chassis frame is divided into upper and lower parts. The bottom is equipped with adjustable support feet and vibration damping pads. The upper frame supports the covered container, mixing system, cutting system, and discharge device. The lower frame mainly carries the reducer, motor, and transmission system. The electrical control motherboard is placed inside the lower frame. Frame material: Q235-A. Three sides are equipped with protective cover plates, and the other side is equipped with a movable door made of protective cover plates. Material: SUS304.

2. Covered Container:The container is inverted conical, with a stirrer installed at the bottom center and a granulation cutter on the side. The upper part has a quick-opening cover; the quick-opening cover consists of a cover, cover fixing arm, cover rotating arm, and cylinder. The cover is equipped with a feed port, sight glass, and exhaust device. Material: SUS304.

3. Mixing System:Composed of a motor, frequency converter, reduction device, transmission shaft, modified Bumar-type stirrer, compressed gas sealing device, and rotating air gap seal. Material: 45#/SUS304.

4.Cutting System:Composed of a motor, frequency converter, transmission components, multiple U-shaped cutting blades, and gas sealing components.

5. Discharge Device:Composed of a discharge seat, discharge plug, discharge port, and guide rod.

6. Control System:Composed of a PLC programmable controller, complete electrical components, pneumatic components, and a human-machine interface operation screen.
