multi-stage linkage roller screen

The multi-stage linkage roller screen integrates feeding, separation and screening functions and can replace vibrating feeders to realize feeding and soil removal.

In mining operations, vibrating feeders are frequently tasked with separating soil and rock from incoming raw materials. However, the primary function of a vibrating feeder is uniform material feeding, and soil-rock separation is only an auxiliary feature. For many working conditions where large volumes of soil need to be screened out, the multi-stage linkage roller screen becomes highly essential.

Yet the core functions of the multi-stage linkage roller screen include coarse-fine separation, soil-rock separation, and sand-gravel separation. Can it double as a feeder? Below we will conduct a detailed discussion on the feasibility of using the multi-stage linkage roller screen as a feeder.

Direct conclusion: The multi-stage linkage roller screen can absolutely be used as a feeder with outstanding performance.

Reasons why the multi-stage linkage roller screen can replace vibrating feeders:

1. It also withstands impact from incoming material. Its thick shafts are made of wear-resistant materials, delivering excellent impact resistance.
2. The speed of the multi-stage linkage roller screen is adjustable. It can push materials forward, so the feeding rate and feed volume can be fully controlled.
3. Separation and screening are its primary functions. It excels at screening soil out of raw materials and can further classify materials by particle size in the subsequent process.

Technical Parameter:

The multi-stage linkage roller screen is driven by multiple shafts in multiple stages to the discharge port. The axes are linked, so the name is multi-axis linkage roller screen. The main function is separation and screening. Applications: quarry, rubble, coal yard, garbage disposal, river cleaning, infrastructure projects, etc.

How to ensure stable feeding of the multi-stage linkage roller screen?

1. Variable frequency speed regulation is mandatory to control feed volume.
2. Height drop must be incorporated into the design to prevent material bridging.
3. Small gaps shall be configured at the feeding end to reduce machine resistance.
4. Sufficient power is required to handle heavy material bearing pressure.
5. Heavy-duty construction: The equipment must adopt a heavy-duty design with 3 to 4 linked shafts, or a single-shaft single-motor configuration.
6. Regular feeding: Maintain a continuous material layer on the screen, which represents the optimal working condition and helps mitigate or eliminate feeding impact.

The application of multi-stage linkage roller screens as a substitute for vibrating feeders has been verified through theoretical research and field practice. Proper machine design is critical; otherwise, malfunctions are likely to occur.
