About Finger Screen And Forged Finger Tines

The industrial world boasts numerous pieces of equipment that play a pivotal role in various processes, improving efficiency, productivity, and safety. Among the multitude of machines, the Finger Screen stands out, especially when it comes to sorting applications. With its innovative Finger Tines, the Finger Screen offers a dynamic solution in the world of material processing.

Its adaptability and efficiency address the challenges faced by conventional screening methods, making it a preferred choice in many industries. As material processing needs evolve, systems like the Finger Screen continue to prove their worth in delivering precise and efficient results.

But what exactly is a Finger Screen, and why is it a favorite choice for sorting tasks? Why is finger tine such an essential part of these machines?

What is a Finger Screen?

A finger screen is primarily used in waste processing and recycling industries. Its main purpose is to sort and separate materials based on size. This is particularly useful in recycling plants where different materials need to be separated for further processing.

The machines work by simply having the material to be sorted and passed on it. The materials that need to be sorted are fed onto the top deck of the finger screen. This is typically done through conveyors or by manual feeding, depending on the scale of the operation.

The sorting process is aided by vibration and oscillation. The screen employs a vibratory motion, which causes the flexible fingers, called finger tines or rod sieves, to oscillate. This motion aids in the stratification of the materials, helping to spread them out evenly across the surface for effective sorting.

As materials cascade down the screen’s deck, they’re classified based on size. Larger items stay on top, while smaller items fall between the gaps created by the moving finger tines. Once sorted, materials exit the screen in separate streams, each corresponding to a specific size range.

That’s simply how this sorting machine works. Finger screen finds a range of applications from waste management, mining, forestry, agriculture, and many others.

What Are Finger Tines?

As already mentioned above, finger screen employs a series of finger-like extensions designed to methodically separate materials based on various parameters such as size, shape, and other physical characteristics. They are called Finger Tines.

Finger tine is an elongated, flexible element typically made of steel or other durable materials. In a finger screen setup, multiple finger tines are arranged in parallel to form a screening surface. The spaces in between these tines allow smaller particles to pass through while larger objects remain on top.

Depending on the materials that are being sorted, finger tines are from a wide range of materials, but in most cases, steel and steel alloys. Of course, the finger screens used in waste management and mining will have tines made from very different materials due to the difference in abrasiveness and hardness of the materials being sorted.

The Making of Finger Tines

Today, most of the finger tines are forged. The forging technology is enabling manufacturers to produce high-quality and affordable tines, compared to other forming technologies. The forged process of finger tine follows the same process as other forging.

The material is selected, in this case, steel material. The dies are made, and depending on the forging method, the setup for the finger tine forging is prepared. Though cold forging is quickly gaining popularity, hot die forging is still widely used for making tines.

However, whether cold forging or hot forging, the quality of the final forging is what manufacturers must ensure. Therefore, buyers need to pay a lot of attention to the quality of the forged finger tine.

4 Major Benefits of Forged Finger Tines

Durability & Strength: Forged finger tines have a more refined grain structure and fewer inclusions, ensuring they can withstand the stresses of tilling better than those produced using other methods.

Cost-effective in the Long Run: While the initial cost of tines might be high, the longevity of forged finger tines means less frequent replacements, thereby reducing long-term costs.

High-Quality Tines: The final forgings get checked for defects and quality consistency. This may involve tests for hardness, tensile strength, and other mechanical properties.

Customization: Forging allows for a wide range of shapes and sizes, ensuring that finger tines can be tailor-made for specific tasks.
