Movable Vibrating Screen Overview

A movable vibrating screen, also known as a portable vibrating screen or a mobile vibrating screen, is a versatile screening equipment used in various industries for separating and classifying materials. 

The vibrating screen deck(s) contain one or more layers of mesh or perforated plates that allow particles of different sizes to pass through, separating them into different fractions or grades. The screen deck(s) are vibrated either by eccentric shafts or by vibrating motors, which create a high-frequency vibration that helps to move and separate the material efficiently.

Movable vibrating screens are commonly used in industries such as mining, construction, recycling, and aggregate processing, where materials need to be screened and sorted on-site or at multiple locations. They offer the advantage of flexibility and mobility, allowing for easy relocation to different work sites as needed.

The features and applications of movable vibrating screens

Portability: The primary advantage of movable vibrating screens is their portability. These screens are mounted on wheeled or tracked chassis, allowing them to be easily transported to different locations, such as construction sites, quarries, mining operations, or recycling facilities.

Versatility: Movable vibrating screens are versatile and can be used for a wide range of applications, including screening aggregates, minerals, ores, construction and demolition waste, biomass, soil, compost, and more. They are commonly used in industries such as construction, mining, recycling, agriculture, and environmental management.

High Efficiency Screening: These screens utilize vibration to separate and classify materials based on particle size. The vibrating motion agitates the material, allowing smaller particles to fall through the screen mesh while larger particles are retained for further processing or disposal.

Adjustable Configurations: Movable vibrating screens often feature adjustable settings and configurations to accommodate different screening requirements. Operators can adjust factors such as vibration amplitude, frequency, and screen inclination to optimize performance for specific materials and applications.

Ease of Operation: Despite their advanced functionality, movable vibrating screens are designed for ease of operation. They typically feature user-friendly controls and interfaces, allowing operators to adjust settings, monitor performance, and troubleshoot issues efficiently.

Durable Construction: To withstand the rigors of transportation and operation in various environments, movable vibrating screens are constructed with durable materials and components. They are engineered to withstand heavy loads, vibration, and exposure to harsh conditions.

Environmental Benefits: Using movable vibrating screens can offer environmental benefits, such as reducing the need for multiple fixed screening installations and minimizing transportation distances for materials, thereby lowering fuel consumption and emissions.

Movable Vibrating Screen Working Principle

A movable vibrating screen, also known as a portable vibrating screen or a mobile vibrating screen, operates on the same principles as a stationary vibrating screen but with the added flexibility of mobility. Here's a brief overview of the working principle of a movable vibrating screen:

Vibration Mechanism: Like stationary vibrating screens, a movable vibrating screen also relies on a vibrating mechanism to generate vibrations. This mechanism typically consists of an electric motor with an eccentric weight attached to it. As the motor rotates, the eccentric weight creates vibrations in the screen box.

Screen Box: The screen box is the main component of the vibrating screen where the material is separated based on size. It is typically made of steel or other durable materials and contains the screen mesh or panels through which the material passes.

Screen Mesh/Panel: The screen mesh or panels are the surfaces through which the material is sieved. They come in various configurations and sizes depending on the application and the desired particle size distribution.

Material Feed: Material is fed onto the vibrating screen either by a conveyor belt or directly from a hopper or chute. The material spreads evenly across the screen surface due to the vibrations.

Screening Process: As the material moves across the vibrating screen, particles smaller than the screen openings pass through the mesh or panels and are collected as undersize material. Larger particles remain on the screen surface and are discharged at the end of the screening process.

Adjustability: One of the advantages of a movable vibrating screen is its adjustability. Operators can adjust the inclination angle of the screen deck to optimize the screening process for different materials and operating conditions.

Mobility: The key feature of a movable vibrating screen is its mobility. It is mounted on a wheeled chassis or trailer, allowing it to be easily transported to different job sites or locations where screening is required. This flexibility is particularly beneficial for industries such as construction, mining, and recycling, where materials need to be screened at various locations.
