The swing granulator uses mechanical extrusion to produce uniform particles from powdered raw materials. Its core structure includes a wheel, a drum, and a mold (screen) with an aperture. During operation, the motor drives the wheel to perform regular swinging motion, driving the drum to repeatedly compact the powder inside the mold. The powder is forcibly squeezed into the holes of the mold under the pressure between the drum and the mold, forming a strip-shaped object, which is then cut by a cutting blade or rotating blade outside the mold to form particles of the desired length. The entire process is continuous production, and the particle size can be controlled by adjusting the mold aperture and cutting speed.

​The extrusion spheroidization machine is the core equipment for preparing microspheres in modern pharmaceutical industry. Through the two-step process of "extrusion spheroidization", it can efficiently produce spherical particles with uniform particle size and high roundness. Taking the preparation of traditional Chinese medicine microspheres as an example, this article provides a detailed analysis of the equipment operation process and key parameter control.

In the pharmaceutical, chemical, food and other industrial fields, making uniform pills from powder materials is a key process, and centrifugal pill making machines have become the core equipment of this process due to their efficient and precise pill making capabilities.

Rotary extruders are widely used in plastic processing and other fields, and their stable rotational speed is crucial for producing high-quality plastic products. However, in actual use, there may be situations where the rotational speed is unstable, which not only affects production efficiency but may also cause damage to product quality. Next, let's analyze the possible reasons for the unstable speed of the rotary extruder.

As an important production equipment, the rotary extrusion machine has a wide range of applications in industries such as chemical, plastic, and rubber. Its core components‐ — The rotational speed of the screw has a crucial impact on production efficiency and product quality. T
