High-yield stainless steel food-grade tumbler sieve grain separator

Product Introduction

The swing screen is a screening device that simulates the actions and processes of manual screening. Under the action of the driving device, its screen surface performs three-dimensional circular motion, featuring a combined motion trajectory of reciprocating vibration and circular shaking. It enables materials to move forward in a spiral shape on the screen surface and be screened layer by layer. It has the characteristics of high screening accuracy, large processing capacity, and long screen life. It is widely applied in fine screening operations in fields such as chemical engineering, food, and mining.

Working principle

The working principle of the swing screen is to simulate the actions and processes of manual screening, making the screen surface generate specific compound motion trajectories, thereby achieving the screening of materials. Specifically, it is as follows:
- Power transmission and motion generation: The drive device (such as a motor) transmits power to the screen box through a transmission mechanism (such as eccentric blocks, connecting rods, etc.), causing the screen surface to move in a three-dimensional direction.
- The formation of a compound motion trajectory: The screen surface does not vibrate in a single direction but simultaneously has reciprocating vibration in the horizontal direction and circular shaking in the vertical direction, forming a compound motion trajectory similar to the artificial shaking of a screen (usually three-dimensional circular motion).
- Material screening process: After the material is fed into one end of the screen surface, under the action of compound motion, on the one hand, it moves forward in a spiral shape along the screen surface, prolonging the residence time on the screen surface. On the other hand, due to the differences in force and motion states of materials of different particle sizes, fine particles fall through the screen holes, while coarse particles are discharged from the other end of the screen surface, thus achieving classification and screening.

Product Features

1.High precision: Three-dimensional motion achieves fine screening ranging from 0.074 to 5mm, with a penetration rate exceeding 95%.
2. Large processing capacity: The spiral forward trajectory extends the material residence time, and the production capacity is 30% higher than that of traditional screens.
3. Durable screen mesh: Gentle movement reduces wear and tear, extending service life by 50% to 80%.
4. Low noise and environmentally friendly: Sealed structure + shock-absorbing design, noise ≤75dB, and less dust.
5. Adjustable trajectory: The amplitude can be adjusted by eccentricity/rotational speed to adapt to the characteristics of different materials.
6. Multi-layer classification: 2 to 5 layers of screens are integrated for operation, allowing for the output of multiple particle sizes in one screening.
7. Easy maintenance: The modular structure makes it convenient to disassemble key components and reduces maintenance time.
