How to select Banana Screens?

Banana screens are a type of vibrating screens that are designed to achieve higher throughput and efficiency than conventional horizontal screens. They have a curved shape that resembles a banana, hence the name. Banana screens are used for various applications, such as coal processing, mineral recovery, scalping, and dewatering.

To select a suitable banana screen for your needs, you should consider the following factors:

The size, moisture, and density of the material you want to screen. These affect the capacity, performance, and product quality of the screen. You should choose a screen that can handle the feed size range and achieve the desired moisture content and recovery rate of the product.

The feed rate and consistency of the material. These affect the material travel velocity and bed depth on the screen. You should choose a screen that can operate at an optimal speed and slope to minimize the bed depth and maximize the screening efficiency.

The number and angle of the deck slopes. These affect the screening area and the material stratification on the screen. You should choose a screen that has enough screening area and appropriate deck slopes to separate the material into different fractions according to their size and density.

The type and quality of the screen panels. These affect the durability, wear resistance, and maintenance of the screen. You should choose a screen that has suitable screen panels for your application, such as polyurethane, rubber, wedge wire, or woven wire. You should also choose a screen that has easy access to replaceable parts and wear liners.

The type and quality of the drive unit. This affects the vibration amplitude and frequency of the screen. You should choose a screen that has a reliable and efficient drive unit, such as a vibrator motor or a geared exciter. You should also choose a screen that has adjustable vibration parameters to optimize the performance and efficiency of the screen.

I hope this helps you select a banana screen that meets your requirements.
