Introduction
Linear vibrating sifter is used to separate materials into various particle sizes for further processing.Basically, professional large capacity mining linear vibrating screen manufacture consists of the screen box, supporting device, driving unit,vibration isolation and etc. It has two operational driving modes: dual-vibration mode (light duty) and dual-vibration exciter mode(heavy duty).
Working Principle
The vibrating source is also from vibrating motor. There are two motors to be fixed on the both side of screening box(or under the screening box) to corotate on the contrary direction. In the process of rotating, when two motors synchronous reversely rotate, the eccentric blocks of motor will emerge a kind of centrifugal force, which can be transmitted to the screening box and make the machine run by linear direction. Then the material on the mesh will be vibrated forward and screened.
There is an angle of inclination two motor axis's relative to screen deck, under the influence of resultant force of exciter force and materials self weight, materials are threw up to make saltatory and linear movement forward on the screen deck in order to screen and grade the materials. By choosing the suitable mesh, the screening target is realized.
Features
High productivity
Tightness, very little dust spilling, also can be enclosed or can be connected with duct collector.
Low energy consumption, low noise and long service life.
Screening of high precision, large capacity, simple structure.
Fully enclosed structure, automatic layout, Easy maintenance
It can be used for assembly line production automation.
Sieve body parts are used rolled welded steel plate and profiles (part of the group as a bolt connection between the body) the overall stiffness is good, solid and reliable.
Application
The linear vibrating screen can be applied to the screening and grading of powder and granular materials.
It is widely used in plastics, building materials, metallurgy, rubber, ceramic, food, pharmaceutical, chemical, carbon, abrasives, fertilizer, glass,ceramics and other industries.
Introduction
This machine is composed of screen box, vibrating motor, damping system and bottom rack. Screen box is consisted of deck base, screen plate, scale-board etc.
It adopts high function and long life YZO series vibrating motor or exciter as exciting source to adjust the size of exciter force, in order to change swing of sifter machine.
The damping system is made up of rubber spring, hoop and supporting base. The bottom rack is consisted of hopper and chasis rack, installation method of exciter source is divided into upper vibrating or under vibrating, installation method of vibration reducer is divided into base or suspention. We also can design and manufacture according to users requirement.
Working Principle
Screen self-synchronous reversed rotation depends on two sets of same vibrating motors or general motors along with exciter, and makes the whole screen machine supported on vibration reducer moves on a linear trajectory quickly go ahead and loose to complete screening operation after materials fall into screen from inlet.
XBZS series cantilever bar vibrating sifter is driven to rotate synchronously in opposite directions by two same vibration motors or electric motors with exciters, which makes the screen body move on periodical and to-and-fro linear trajectory to achieve screening classification.
Features
The deck of bar screen should be inclined installed, the angle is during 20 degree to 35 degree. When comparing with other same type has following difference:
1.small volume , big inclined angle and screening capacity.
2.light weight, easy installation.
3.low price and energy consume.
4.simple construction and beautiful shape.
5.the efficiency of the screen mesh is more over 20% than the general screen mesh.
6.self-cleaning.
7.specially using for secondary screening under the high furnace groove.
8. Large inclination installation of screen surface(20°-35°), small volume, large capacity.
9. Light weight for easy installation;low power consumption for energy-saving.
10.Low cost and little spare parts;simple structure and attractive appearance.
11.Self-cleaning function, specially for secondary screening below blast furnace bin.
Application
XBZS series bar screen is a new type screen equipment , Suitable for the classification of big materials, medium and small granular materials. it is widely used in mining, coal, energy power, metallurgy, building materials, fire-resistant, etc.
Round vibrating screen machine is one kind of high effective sieving equipment, which has been widely used in domestic & foreign market. It adapts the principle of vibration to realize the sieving of plenty of raw materials. It is wide used for metallurgy industry, chemical industry pharmaceutical industry, grain industry and so on.
Double Deck Vibrating Screen is mainly used in desulphurization system of power plant, in flux screening system of steel plant, in the gravel aggregate system of construction industry, etc.
The Double Deck Vibrating Screen research and developed is basing on our high frequency screen, and it is with the character of a low-amplitude but a high-frequency. It is especially for the separating of fine material which is less than 5mm
Features:
1. Double Deck Vibrating Screen changed the structure of the traditional vibrating screen sieve surface and screen box vibration, using multi-independent sieve surface vibration, sieve box and rack do not vibration movement.
2. Each section of sieve plate independent vibration source, independent vibration. According to the size distribution of the material in the field, the size of the material, the amplitude and the vibration frequency of each sieve surface can be adjusted adaptively to achieve the best combination of processing capacity and screening efficiency.
3. Less moving parts, the vibration quality is reduced and the power is small.
4. Screen box does not participate in vibration, so it is easier to achieve a fully enclosed structure, so that dust does not leak to meet the higher environmental requirements.
5. Sieve plate mainly used grizzly, comb, round steel welding, steel punching and so on.
The High Amplitude Vibrating Screen is an ideal screening equipment which is developed by our designers, humid and sticky material can be screened by the device, because the device solves the problem of blocking screen meshes, it is especially good at screening humid and sticky raw coal which aperture is ï¼?10mm. The equipment has a characteristics of a high screening efficiencyã??low noiseã??cost saving etc. This equipment can be applied to the coal industry (particle classification)ã??the electric industry (CFB boiler fine size screening)ã??the metallurgy industry (particle classification) etc.
The vibrating frame screen is used for the coarse selection and purification of pulp. Through the frequency vibration, the coarse pulp of the joints, film and other coarse impurities are screened out. The good pulp has been entered into the following process through the sieve plate. The vibrating frame screen has the advantages of simple structure, simple maintenance, low production cost and high production efficiency. It is the ideal cleaning equipment for the pulp mill. This equipment is divided into high frequency vibration frame type, low-frequency self-washing type and high frequency self-vibration type.
Application:
Vibration screen is widely used for coarse screening of different kinds of pulps such as chemical pulp,semi-mechanical pulp,TMP and waste paper pulp.
Spring type and condole belt type two kinds structure characteristic.
It is also used in fiber recovery from the rejects and scruff pulp in the pressure screen and separator.
Design Features:
Damping device is made of special rubber screen frame vibrate steady.

Air seal room is special,screen plate has higher self-cleaning ability.
Linear vibrating screen adopts double vibrating motors as power source, with the specific working mode of these two motors make the materials be thrown up on the sieve and go forward in a straight line.
