Banana Screen

Banana Screen

Why a vibrating screen is called banana screen?

It is that distinctive shape that gave the multi-sloped screen the name “banana”. In industry, the “banana” term is used interchangeably with “multi-sloped”, hence multi-sloped screen, instead of banana screen.

Summary:

Used in wet and dry applications, banana screens are vibratory equipment which use the distinctive shape to process larger volumes of material using a smaller footprint. This is compared to inclined horizontal screens, which as the name implies are horizontal and don’t have the banana shape.

Structure:

Application:

The banana screen is widely used in coal, metallurgy, mining, transportation, electricity, and chemical industry, mainly used in grading and dehydration fine materials, from mud, sculping.

Banana screen are used for size classification and material screening. It has varieties of application range:

• iron ore & gold power
• coal power
• aggregates
• sand & gravel
• hard rock, limestone, ore

Features:

• Much larger feed quantity with the same screen area than conventional sieving machine, Multiple screen surfaces, easier to sieve
• Infeed end with large inclination allows rapid movement of materials, rapid stratification, thus more conducive to sift through the material. The big bulk material properties can quickly close the screen surface, strengthening through sieve effect
• Improved efficiency in sizing material due to formation of a thin bed depth.
• Lower water consumption, can with wet screening.
• Lower energy requirement, for an equivalent throughput on a conventional flat deck screen.
• Higher feed rates for an equivalent deck area.

Media:

To separate material, banana screens use different media. Choice of media, e.g., woven wire, rubber, polyurethane, is guided by the ore/material being processed, the tonnage of throughput and so on.
