What’s The Structure And Working Principle Of Banana Screen?

Banana screen is a large and medium-sized screening machine with large screening capacity, suitable for screening sintered ore, coal, limestone, crushed stone, gravel, metal or non-metallic ore and other materials. The following is a detailed introduction to the structure and principle of the banana screen.

What’s the structure of the banana screen?

The structure of the banana screen includes a spring, motor, vibrator, intermediate shaft, drive shaft, screen frame, screen beam, screen plate rail seat, polyurethane screen plate, etc. The shape of the screen box is similar to that of a banana, so it is called a banana screen. The vibrator mainly comprises an eccentric shaft, pulley, bearing, and bearing seat, etc. The vibrator is installed on the side plate of the screen box and connected to it by the motor through a V-belt or a flexible connection. The motor drives the eccentric shaft to rotate, generating centrifugal inertia force, forcing the screen box to vibrate.

What’s the working principle of the banana screen?

The working principle of the banana screen is to use the throwing motion of the material on the screen surface to simulate the effect of tumbling screening, and to allow the material to be naturally screened by combing, turning, and evenly distributing the material layer by layer. There is a large slope screen surface at the feed end, and then it descends step by step at a certain number of angles until it reaches the discharge port. The slope screen surface at the feed end allows more materials to pass through the screen surface with a higher screening speed and thinner material stratification. Because large pieces of material pass through the steep slope faster, this early stratification allows fine particles to approach the screen surface faster and pass through the gap relatively unhindered.
