Multi-layer Horizontal Screening Machine Which Allows the Materials to Screen and Grade Accurately.

Linear vibrating screen, also known as linear motion vibrating screen, the motion is linear, used for screening, classifying, deblocking, dewatering any lumpy solids or slurries, it uses a vibrating motor to throw up and forward linear motion Materials, these models are usually run with dual vibration motors that operate in synchrony, centrifugal force and gravity help throw the material in the direction it's moving, multi-layer systems can separate the product into 2-7 different parts, in Multi-stage separation is completed while removing impurities.

layers of linear vibrating screen

Linear vibrating screen can provide 500mm to 1,500mm wide and 1,500 to 4,000mm long screening area, allowing up to 20 tons / hour of processing capacity, suitable for a variety of dry 0.074-5mm particle size, moisture content less than 70%, non-sticky For the screening of powdery materials, the maximum feeding particle size is not more than 10mm.

Function of Linear Vibrating Screen

linear vibrating screen works

Linear vibrating screens have the ability to convey while separating and are often used for container filling and safety screening – preventing clumping, oversized products or large particles that could cause problems in subsequent processing or quality control, while maintaining optimum performance for further processing. feed rate. Another common application is to combine a hopper with a screen - unloading material from the hopper, removing fines and feeding the material to the inspection table, improving inspection efficiency. It can be equipped with single-layer or multi-layer screens, and can continuously screen up to 7 products at a time.

Successfully used for:

Coarse grading - grading bulk materials that do not require extreme dimensional accuracy

Fine Classification - Provides high precision for particle sizes from less than 3 mm to 50 microns

Dust removal - for extraction of undersized particles

Protective Screening - Used to remove oversized particles, impurities and other foreign bodies, etc.

Separation - remove coarse material from fine material

Dewatering - used to recover solids from wash media

Extraction - Used to remove insoluble impurities from washing and carrier liquids.

Working Priciple of Linear Vibrating Screen

The linear vibrating screen relies on two reverse motors of the same frequency to make the material jump straight forward on the screen surface. After a large number of broken materials with different particle sizes and mixed thickness enter the screen surface, only a part of the particles contact the screen surface. The vibration of the box loosens the material layer on the sieve, which further expands the existing gap of the large particles, and the small particles take the opportunity to pass through the gap and transfer to the lower layer. Due to the small gap between the small particles, the large particles cannot pass through, so the original is disorderly. The arranged particle groups are separated, that is, stratified according to the particle size, forming an arrangement rule that the small particles are at the bottom and the coarse particles are at the top, so as to achieve the purpose of screening and sorting materials.

Benefits of linear vibrating screen

Rough cleaning and screening

It is suitable for sieving any dry material of 0.74mm-5mm, the maximum particle size is 10mm, and the sieving accuracy reaches 200 mesh (0.074mm).

Selection tips:

1. The shape and size of the sieve hole: the particle size of the circular sieve is smaller, and the size of the square sieve is larger.

2. The length and width of the screen surface: the model is determined by the length and width of the screen surface of the sieve (such as a 1025 type sieve, representing 1000mm (width) x 2500mm (length)), the wider the screen surface width, the thinner the material layer thickness will be , the greater the output, the longer the length of the screen surface, the longer the screening time, the more chances of sieving, and the higher the screening efficiency. Generally, the appropriate width-to-length ratio is 1:2~1:3.

3. Screen surface inclination: In general, linear vibrating screens can be installed at a certain angle. If the inclination is too small, the material movement speed will be slow and the productivity will be greatly reduced. If the inclination is too large, the discharge will be too fast and the screening efficiency will be reduced. , so the inclination angle should be appropriate. Generally, we suggest that the inclination angle of the linear vibrating screen is 0-15°. If special materials are to be screened, the inclination angle can be increased appropriately, but it should not exceed 25°.

4. Motor excitation force: must be higher than 30% of the total weight of the linear screen.

Motor Installation

Available Options

The linear vibrating screen can be designed and customized according to the actual use requirements, such as the installation position of the vibrating motor, the type of screen, adding a batcher at the feed inlet, the feed inlet can be designed as a circle or square according to the relevant configuration pipeline, the shape, size and outlet The height of the feed port can also be customized according to actual use requirements.

Motor installation position

Motor installation position

The vibration motors are installed on both sides of the linear vibrating screen: it is suitable for occasions where the overall height of the equipment is limited, but the width of the equipment is not limited. For example, due to the special requirements of some materials, the discharge port of the equipment cannot be too high. If the vibration motor is also installed at the bottom of the linear vibrating screen, the overall height of the equipment cannot be well controlled.

The vibration motors are installed at the bottom of the linear vibrating screen: the motor is installed at the bottom of the equipment, which reduces the overall width of the linear screen, thus ensuring the shielding area of ​​the equipment without affecting the throughput and shielding efficiency.

The vibration motors are installed on the top of the linear vibrating screen: If the height and width of the outlet of the customer's linear screen equipment are limited, no matter whether it is installed at the bottom or on both sides, the vibration motor cannot meet the requirements. At this time, the vibration motor can be installed in the middle of the top of the equipment, which will neither increase the width of the equipment nor affect the height of the discharge port of the equipment.

Different Types of Screen

Different screen types

Linear vibrating screen can provide different screen types to achieve different screening goals.

The types of screens that can be included are:

1.Woven wire mesh

2.Laser cutting of punched plates


4.Grid bars

Different Outlet Design

The discharge port of the linear vibrating screen can be round or square, and the direction of the discharge port can also be designed according to needs, such as left, right, downward, and forward.


Frames of Different Materials

There are two main types of linear vibrating screen mesh frames: wooden mesh frame and iron mesh frame. So which mesh frame should customers choose when purchasing linear screen equipment? First of all, let's have a simple understanding of these two mesh frames.

1. Wooden mesh frame: It mainly uses high-quality poplar, red pine and white pine as raw materials. Net cleaning devices such as bouncing balls can be added to increase the net penetration rate, which can prevent the clogging of the linear vibrating screen. It is very suitable for granular, powdered sieving of materials.

2. Metal grid: The material can be divided into Q235 carbon steel and 304 stainless steel. The metal mesh frame is mainly made of Q235 carbon steel or 304 stainless steel as raw materials. The screen is strong and durable, and can ensure the screening quality of materials. It can be used to screen large particles and materials with heavy specific gravity.

Q: What is the inclination angle of the linear vibrating screen?

A: Generally 0°~15° (the inclination angle can be increased according to special materials, not more than 25°)

Q: The linear vibrating screen generally chooses several layers for better effect?

A: The linear sieve can be separated in multiple stages. The 1-6 layers of the screen can screen 7 kinds of specifications. The size of the particles after screening is uniform, but it is generally recommended not to exceed 5 layers, and the number of layers is too much. The excitation force cannot transmit the force well.
