Differences Between Inclined vs. Horizontal Dewatering Screens

In producing high-quality aggregate materials, businesses have long utilised highly functional dewatering screens. Dewatering screens, after all, can perform numerous functions throughout their service life. They can effectively dewater, deslime, de-grit, rinse, scrub, size, and wash sand, gravel, crushed aggregates, and other types of materials so that they can be used in the construction industry.

Given the entire composition of dewatering screens, they can easily produce a much drier material. They can even be utilised in handling different sizes of materials to effectively cater to all the needs of specific businesses. Their capability to handle multiple products likewise make them truly versatile.

To date, there are two types of dewatering screens that are commonly used in businesses and worksites. These dewatering screens are inclined dewatering screens and horizontal dewatering screens.

Inclined Dewatering Screens

Inclined dewatering screens normally operate from 20° to 39° and vibrate in a circular motion to process the feed. And with the combination of their inclination and vibration, they would allow the material to travel towards their discharge end while the water is screened out through their accompanying screening media. The combination of these elements also allows the dewatering screens to produce a higher processing rate compared to the horizontal dewatering screens.

One drawback, however, of inclined dewatering screens is that they actually limit the amount of time a feed could spend on the screen. This limitation can affect the overall sorting efficiency of these pieces of machinery. While decreasing the inclination of the dewatering screens can improve the sorting efficiency, their product might end up relatively wet, which can cause issues to customers or clients. Moreover, they are only recommended for portable and stationary plants as they require more headroom.

Horizontal Dewatering Screens

Horizontal dewatering screens, on the other hand, normally operate at around 0° to 10°, with some setting them up at an incline of -3°. During their operations, horizontal dewatering screens utilise a vibrating motor to effectively move the feed down the screening media. Compared to inclined dewatering screens, the horizontal dewatering screens allow the feed to spend more time on their screens, yielding a better and higher sorting efficiency. They can likewise produce better separation and reduced material loss.

But just like inclined dewatering screens, horizontal dewatering screens also have a disadvantage. Horizontal dewatering screens can only process a limited amount of material per hour, making the process somehow slower compared to the inclined ones. This disadvantage, however, makes them great since they can produce materials with better quality and drier overall composition.
