[feed size]: ≤300mm

[production capacity]: 250-1500t/h

[application scope]: Metallurgy, mining, coal, building materials, refractory, grain and other industries

[product introduction]: The high amplitude vibrating screen is a screening equipment specially developed by our company to solve the deep screening of wet and sticky materials. With large amplitude, high vibration intensity and low vibration frequency, it can complete the screening process of wet and sticky materials on the screen surface by self-cleaning. The high amplitude vibrating screen has changed the mechanical structure of the traditional screen surface and screen box vibrating together. It adopts the movement mode of multi-stage independent screen surface vibration while the screen box and frame do not vibrate. The multi-stage screen surface vibrates independently from the material inlet to the discharge end, and the amplitude and vibration intensity of each section of screen surface are adjustable.

Product introduction

High amplitude vibrating screen is a screening equipment specially developed by our company to solve the deep screening of wet and sticky materials. With large amplitude, high vibration intensity and low vibration frequency, it can self clean the screening process of wet and sticky materials on the screen surface. For the screening of wet sticky materials less than 10 mm, it has a good solution to the problem of screen blocking. The obvious characteristics of the equipment are segmented screening, the whole screen does not vibrate, and the screen vibrates. It is especially suitable for coal (particle size classification), power (CFB boiler fine particle screening), metallurgy (particle size classification) and other industries.

Product advantages

1. Because the high amplitude vibrating screen adopts the process characteristics of no vibration of screen body and screen vibration, the dynamic stress of the screen can be reduced. Therefore, the vibration amplitude is large and the vibration intensity is large, and only a small dynamic load is needed to complete the adhesion The wet material can be sieved and the double amplitude can reach 15-25 mm.
2. The structural design of multi-stage screen is different from that of ordinary vibrating screen. It does not participate in vibration as a whole. The side plate, top cover and base of the screen are fixed parts, and only the screen screen and vibration exciter bearing are referred to And vibration, so it is a structural mode of segmented screening and screen vibration without overall vibration.
In addition to this equipment, there are two vibrating bars in each screen frame It can largely eliminate the sticking problem of wet sticky raw coal to screen screen. Compared with ordinary vibrating screen, the screen surface area and mesh opening rate are much larger, so the screening efficiency is higher. And the screen bar of the equipment is vulnerable High amplitude vibrating screen can save money for users to a great extent.  
four High amplitude vibrating screen, less moving parts, small vibration quality, can reduce the power to the minimum. Compared with the traditional screen, the power can be reduced by one time.
5. The equipment is a kind of environmental protection screening equipment, which can adopt a fully enclosed structure to prevent dust from leaking out High amplitude screen used in coal-fired power plant is usually closed structure to prevent dust leakage and adapt to environmental requirements.
6. The whole machine is controlled and operated by PLC control system, and a series of actions such as equipment startup, shutdown and top cover opening can be completed remotely. The equipment generally uses 1-5 motors for vibration, and the starting time interval of each motor is 6 -8 seconds, forward start, reverse shutdown, empty car start purpose, screen machine does not store material, convenient observation and maintenance.
7. The high amplitude vibrating screen is generally driven by 1-6 sets of motors, and the starting time interval of each motor is 6-8 seconds. The screening machine without material is more convenient for observation and maintenance.
8. Modular and standardized components are adopted to make the overall quick replacement and greatly reduce the online maintenance time.
9. The vibration components of the equipment have been modularized and standardized during manufacturing, which can be quickly replaced as a whole. It can greatly shorten the on-line maintenance time, improve the work efficiency and be easy to maintain.

working principle

The high amplitude vibrating screen has changed the mechanical structure of the traditional screen surface and screen box vibrating together. It adopts the movement mode of multi-stage independent screen surface vibration while the screen box and frame do not vibrate. The multi-stage screen surface vibrates independently from the material inlet to the discharge end, and the amplitude and vibration intensity of each section of screen surface are adjustable. Because of this structure, the vibration quality of the equipment is reduced, and the large-scale motion parameters and screening equipment are easy to be realized, and the screening process requirements and screening mechanical strength requirements with large vibration intensity are met.
