Vibrating screens are one of the main types of industrial screening equipment. There are several mechanical screening solutions for the solid waste management, recycling and aggregates industries; however, vibrating screens offer a number of unique advantages that make them a first-line choice for a variety of industrial applications.
Read on to learn more about how vibrating screens work and the benefits they offer compared to other common types of screening equipment.More details information you can also visit our Instagram Pages.
What is a vibrating screen?
As the name suggests, the vibrating screen design is based on the principle of transmitting vibration to the screen surface in order to separate and classify different particles by size.
Regardless of the machine’s design, the principle is the same: The vibrations break the surface tension between the particles, forcing them to separate. Smaller particles, known as “fines,” then pass through the sieve surface. At the same time, oversized particles are carried across the surface of the screen. This is an important application in many industries, especially mineral processing.
Due to their unique design features, vibrating screens offer specific benefits over other materials processing equipment, including:
Improve processing and material quality
While certain screening equipment is better suited for different materials, vibrating screens offer several advantages in aggregate and mining material processing. The vibrating screen equipment is particularly complete to meet the fineness requirements of these industries. Their design generates the force needed to separate oversized particles from fines, making it easier to recycle the product – even when handling materials that require much smaller size separations. This results in higher yields and an improvement in the overall quality of the final product.
Lower operating costs
Shakers are known for their robust design. Due to the relatively simple working principle and the streamlined design of modern machines, vibrating screens can generally be purchased for less than other types of screens. This results in less upfront investment.
Additionally, vibrating screens are able to operate with lower energy consumption than more complex machinery, saving businesses money in ongoing operating costs. Finally, since the higher frequency vibrations are transferred directly to the screen deck, only the screen media needs to be replaced periodically. This can help save on maintenance and repair costs typically associated with other screening equipment options.
Less maintenance and downtime
Maintenance and downtime due to repairs or equipment failure can result in significant loss of productivity and profit. Many types of screens experience significant wear and tear, especially in demanding applications such as polymerization processing. However, vibrating screens offer the advantage of less maintenance and downtime. This is a result of their design, which centers on transmitting vibrational forces only to the screening surface.
In addition, high-quality vibrating screening equipment is designed and manufactured so that other parts of the machine are minimally affected by the vibrating force. In more complex designs, the construction of the machine allows adequate absorption and damping of vibrations outside the screen media. This results in fewer moving parts and a machine with less overall wear and tear, further reducing downtime and maintenance.
Higher screening efficiency
While there is a wide range of screening equipment on the market, vibrating screens offer an ideal choice when an operation requires a simple solution that can handle higher feed flows. In fact, vibrating screens work most efficiently with consistently high flow rates. With other types of screening equipment, the same material throughput can result in screen blinds or material backflow, requiring slower feeds.
