There are 3 ways to choose the right filter. It can help customers to better purchase screen changers. In industrial production, screen changer plays a vital role, it can effectively filter the impurities in the material to ensure product quality. But there are a variety of screen changer models on the market, how to distinguish between different filters and choose the right product for their needs?

Three ways to differentiate between filters

1.According to the filtration mode:

the screen changer filtration mode is mainly two kinds: manual screen changer, automatic screen changer. Manual screen changer structure is simple, low cost, but need to stop operation when changing the screen, affecting production efficiency, commonly used in small production enterprises or production continuity requirements are not high scene, such as some small plastic products processing plant.

Such as some small plastic products processing plant. Automatic screen changer can be completed without stopping the case of changing the screen, can be divided into slide type, drum type, plunger type and so on. Skateboard type automatic screen changer through the movement of the skateboard to realize the screen replacement, screen replacement speed; The drum type uses the drum to rotate to switch the screen, which is suitable for high output and continuous production, such as large chemical fiber manufacturers commonly used in this type.

2.According to the applicable materials:

different materials have different characteristics, the requirements of the screen changer are also different. For example, for high-viscosity materials, such as rubber, you need to choose the screen changer model that has strong pressure tolerance and the screen is not easy to be blocked; while for low-viscosity materials, such as some plastic granules, ordinary screen changer can meet the demand.

For low-viscosity materials, such as some plastic particles, ordinary screen changer can meet the demand. If the material content of impurities and large particles, you need a larger filter area and thicker screen changer.

3.According to flux size:

Flux is the amount of material that passes through the screen changer per unit of time. Screen changers with smaller fluxes are suitable for small production lines, while those with larger fluxes are suitable for large-scale production. For example, for laboratory production in the research and development phase, a screen changer with a small flux is sufficient; For large-scale industrialized production, a screen changer with higher flux is required to ensure production efficiency.

If it is a large-scale continuous production, automatic screen changer is the first choice, can avoid the production loss caused by the screen change downtime; if it is a small batch, intermittent production, manual screen changer may be more cost-effective. Also consider the material characteristics, such as material viscosity, impurities, and choose to match the screen changer.
