A linear vibrating screen is a screening machine that utilizes a linear motion to convey and classify different types of bulk materials. The linear motion is generated by two vibrating motors with adjustable eccentric weights that rotate in opposite directions. The motion of the vibrating motors is then transmitted to the screen surface, causing the material on the screen surface to move forward in a straight line.

Linear vibrating screens are designed to screen and grade various materials, including granular and powdery materials, as well as liquids and slurries. They are widely used in industries such as mining, metallurgy, chemical, food, and construction materials.

Linear vibrating screens are used in a wide range of application fields due to their ability to screen and grade various materials. Some of the common application fields of linear vibrating screens include:

Vibrating screens are commonly used in a variety of industries, including mining, mineral processing, food processing, and aggregate production. They are used to separate materials based on size, density, and other properties, and are considered to be a highly efficient and cost-effective method of material separation.

There are several types of vibrating screens, each designed to handle specific material separation and sizing requirements. Some of the most common types of vibrating screens include:

Linear Vibrating Screen: A linear vibrating screen uses a vibrating motor to generate a linear motion along the length of the screen. It is used for separation of dry materials such as crushed coal, sand, gravel, and minerals.

Circular Vibrating Screen: A circular vibrating screen uses a circular motion and is used for separation of wet or moist materials such as coal, sand, gravel, and minerals.

Elliptical Vibrating Screen: An elliptical vibrating screen uses an elliptical motion and is used for separation of fine materials such as ceramic raw materials, minerals, and chemicals.

High-Frequency Vibrating Screen: A high-frequency vibrating screen uses a high-frequency vibration to separate fine materials such as minerals, sand, and gravel.

Multi-Deck Vibrating Screen: A multi-deck vibrating screen is used to separate materials into multiple fractions of different sizes. It is commonly used in minerals processing and aggregate production.

Trommel Screen: A trommel screen uses a rotating drum to separate materials. It is commonly used for the separation of dry materials such as coal, sand, gravel, and minerals.

A vibrating screen operation involves using a machine to separate materials into different sizes based on their particle size. The machine consists of a screen deck, vibration mechanism, and a frame. The screen deck is made of mesh or perforated plates and is placed over a frame. The vibration mechanism, which can be either an electric motor or a vibrating generator, creates a linear or circular vibration that causes the material to move along the screen deck. The material is separated into different sizes as it moves along the deck, with larger particles falling through the larger openings and smaller particles being held back by the smaller openings.

The operation of a vibrating screen typically involves adjusting the amplitude, frequency, and direction of the vibration, as well as adjusting the angle and height of the screen deck. These adjustments help to optimize the performance of the screen and improve the efficiency of the separation process. The material to be separated is fed into the machine from the top, and the separated fractions are collected at the bottom of the machine.

Each type of vibrating screen is designed for specific material separation and sizing requirements, and the choice of the most suitable type of vibrating screen depends on the specific requirements of the application.

The process in which the broken material is divided into different particle sizes through one or several layers of sieve surface is called sieving. The vibrating screen is a vibrating screen that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size.

The vibrating screen screening process is generally continuous. After the screening raw materials are fed to the vibrating screen machine (referred to as the sieve), the materials smaller than the sieve size pass through the sieve, which is called the under-sieve product; the material larger than the sieve size passes through the sieve. Continuous discharge on the surface is called over-sieve product.

Vibrating screen machinery is a necessary auxiliary equipment in mine crushing and sand making production lines, and its selection has an important impact on the particle size and grading of the final product.

Factors to be considered in vibrating screen selection:

The characteristics of the sieved material (the content of the size of the material under the sieve, the content of the size of the difficult-to-sieve particles, the content of moisture and clay in the material, the shape of the material, the specific gravity of the material, etc.);

The structure of the vibrating screen (screen area, number of screen layers, size and shape of the screen hole, area ratio of the screen hole, motion mode of the vibrating screen, amplitude and frequency, etc.);

Requirements of beneficiation process (processing capacity, screening efficiency, screening method, vibrating screen inclination), etc.

In addition to considering the above effects, the following basic principles should also be observed:

(1) After determining the sieving area, the width of the sieve surface should be at least 2.5 to 3 times the size of the largest piece of material to prevent the sieve from being blocked by large pieces of material.

(2) In order for the sieve to be in a good working condition, the ratio of the length to the width of the sieve should be selected within the range of 2 to 3.

(3) Reasonable screen material and structure suitable for working conditions should be selected.

(4) Determination of sieve hole size. For fine sieves, curved sieves, and linear vibrating screens for fine particle screening, the sieve size is 2 to 2.2 times the separation particle size, and the maximum is not more than 3 times; for vibrating screens, For screening medium-grained materials, the sieve size is 1.2 times the separation size; for coarse-grained materials, the sieve size is 1.05 of the separation size; for probability sieves, the sieve size is generally the actual separation size 2 to 2.5 times the particle size.

(5) Determine whether to use double-layer or multi-layer sieves. When the particle size range of the material to be screened is wide, when the double-layer screen is used as a single-layer screen, the processing capacity of the vibrating screen can be improved, and the lower screen can be protected, so that the service life of the lower screen can be extended. The selection of the mesh size of the upper screen of the double-layer screen should generally be determined according to the characteristics of the ore feed particle size, and the material particle size equivalent to 55-65% of the original feed amount can be considered as the screen hole according to the underscreen amount of the upper screen. size.

Note that when the content of the under-sieve particle size in the raw material exceeds 50%, there are many difficult-to-sieve particles, and the material has a lot of viscous mud and high water content, try to avoid using double-layer sieves as single-layer sieves.

(6) Determine the effective working area of the sieve. The sieving area calculated according to the requirements of the production process is the effective area of the sieve, and the specification of the sieve is the nominal area of the sieve. For vibrating screens used for screening medium-sized materials, the effective sieving area should be 0.8 to 0.85 of the nominal area of the sieve. times. Of course, this is closely related to the opening ratio of the sieve holes on the sieve surface.

(7) For materials above 200mm, heavy-duty vibrating screens are mostly used; for materials above 10mm, circular motion screens are mostly used; linear vibrating screens and high-frequency vibrating screens are mostly used for desliming, dehydration and classification.

(8) When conditions permit, seat screens should be preferred to facilitate inspection and maintenance. When the hanging screen must be selected, the lifting height should be reduced as much as possible to reduce the swing range of the vibrating screen and facilitate production operations.

In short, when choosing a vibrating screen, you should not only consider one reason, but fully consider various factors to ensure that you choose the equipment that suits your working conditions.
