A horizontal screen, also known as a horizontal vibrating screen, is a type of screening equipment used in various industries, including mining, construction, aggregate processing, and recycling. It is designed to separate and classify particles or materials based on their size. Unlike vertical screens, where the screening surface is oriented vertically, horizontal screens have a horizontal orientation, with the material fed along the length of the screen.
The key features and functions of a horizontal screen
Screening Surface
A horizontal screen consists of a large, flat screening surface that vibrates horizontally. This surface is typically made of woven wire mesh, polyurethane, rubber, or other materials with openings of varying sizes.
Vibrating Mechanism
Horizontal screens are equipped with a vibrating mechanism, such as an eccentric shaft with counterweights, which imparts a linear or elliptical motion to the screen deck. This motion causes the material on the screen surface to move and be stratified.
Material Feed
Material is fed onto the screen deck from one end, typically through a feeder or conveyor. The horizontal orientation allows for efficient material distribution and ensures that the material spreads evenly across the screen surface.
Screening and Separation
As the material moves along the length of the horizontal screen, particles that are smaller than the openings in the screen surface fall through, while larger particles are retained. This separation process classifies the material into different size fractions.
