Which type of screen allows materials to be filtered by having holes or perforations throughout its surface?

A mesh screen is designed specifically to filter materials by utilizing a network of small holes or perforations throughout its surface. This structure allows for the effective separation of particles based on size. When materials are passed over a mesh screen, the smaller particles can pass through the holes while larger particles are retained, enabling sorting and filtration processes.

Mesh screens are widely used in various applications, including water treatment, material processing, and even in household items like strainers. The size of the openings can be adjusted to achieve the desired level of filtration, making them versatile tools in engineering and construction settings.

In contrast, grating screens often consist of bars that create a space for particles to fall through but do not have the fine filtration capabilities of mesh screens. Barminutors and comminutors, while related to processing materials, typically focus on the reduction of particle size rather than filtration. This further distinguishes the mesh screen as the most suitable choice for applications requiring filtration through holes or perforations.
