 Double deck vibrating screen

Introduction: what is a double deck vibrating screen?

A double deck vibrating screen is a screening machine that consists of two decks of screens. The two decks are usually arranged in a V-shape with the top deck having a smaller surface area than the bottom deck. The double deck vibrating screen is used to screen ore particles before they are sent to a crusher or mill for further processing. This type of screening machine is useful for removing oversize material from the feed before it reaches the main processing plant.

The double deck vibrating screen can be custom-engineered to suit your specific needs and application requirements. The decks can be constructed from different materials such as stainless steel, carbon steel, or polyurethane. There are also a variety of screen sizes available to choose from. The double deck vibrating screen is a two-deck screening machine that is used to separate oversize materials from the feed material. The feed material passes through the top deck and then down onto the second deck where it is screened.

How does it work?

The double deck vibrating screen is composed of two decks, the upper and lower. The two decks are separated by a small gap, typically 3-8 mm. The upper deck is usually made of mesh or perforated plate, while the lower deck is covered in rubber or polyurethane. The two decks are vibrated at high frequency, typically between 1200-1800 rpm. The vibration causes the material on the decks to separate and travel up and down the screen.

The double deck vibrating screen is used for screening quarry stone stock and classifying products in mining, metallurgy, building materials, transportation, energy and chemical industries. It has high screening efficiency and large processing capacity.

Advantages of using a double deck vibrating screen

There are several advantages of using a double deck vibrating screen over a single deck one.

Using two decks allows for a higher degree of accuracy when separating materials. This is because the probability of error is reduced when more surface area is available to be screened. Additionally, double deck banana screen are able to handle higher capacities than single deck screens.

Another advantage of using a double deck vibrating screen is that it can help to reduce operating costs. This is because the screen can be operated at a lower frequency, which uses less energy and produces less wear on the screen itself. In some cases, lower frequencies can also lead to improved product quality.

Disadvantages of using a double deck vibrating screen

There are several disadvantages of using a double deck vibrating screen. One disadvantage is that it can be difficult to clean. The screens can become clogged with debris, making it hard to remove all the dirt and grime. Additionally, double deck vibrating screens can be noisy and create a lot of vibration. This can be a problem for businesses that are located near residential areas. Finally, double deck vibrating screens can be expensive to purchase and maintain.


The double deck vibrating screen is a powerful tool for sorting materials, especially when used in conjunction with other equipment. However, it is not a perfect solution for every situation and should be used with care. When choosing whether or not to use a double deck vibrating screen, consider the following:

The type of material you are sorting: Double deck vibrating screens work best with dry, heavy materials such as minerals and metals. If you are sorting lighter, wetter materials such as food or paper, you may be better off using a single deck screen.

The size of the material you are sorting: Smaller particles are more difficult to sort using a double deck screen than larger ones. If your material contains a mix of sizes, it may be best to use a single deck screen for the smaller particles and a double deck screen for the larger ones.
