High Amplitude Vibrate Screen is an efficient vibrating screen designed for processing bulk materials, wet and sticky materials, and materials that are difficult to screen. It is often used for screening in the mining industry. It mainly uses the vibration of multiple layers of screens to make material particles fall into the hopper, and then screen out materials of different particle sizes. The amplitude can reach 8-12mm during the screening process. With the powerful excitation force generated by the heavy-duty vibrator, it can effectively solve industry problems such as material blockage and low screening efficiency. The equipment is equipped with 2-5 layers of wear-resistant screens of different specifications. Through strong vibration, the materials are fully layered and screened, and 4-6 finished products of different particle sizes can be produced at one time. Its unique bouncing ball cleaning system and optional ultrasonic auxiliary device can effectively prevent wet and sticky materials from clogging the screen, and can maintain a stable screening efficiency even when processing sticky materials with a moisture content of up to 15%.
High amplitude vibrate screens are widely used in the mining and coal industries.
A High amplitude vibrate Screen is a vibrating screening device specifically designed for the separation of large-capacity coarse-grained materials. It utilizes a higher vibration amplitude to improve material stratification and screening efficiency, making it particularly suitable for screening mining, aggregate, and bulk materials.
Compared to standard vibrating screens, high amplitude vibrate screen increases material movement speed and reduces clogging.
The biggest feature of high amplitude vibrating screen is its larger amplitude value, which can usually reach 6~10mm or even higher, thereby enhancing the jumping and looseness of the material, so that even wet and sticky materials with high moisture content and easy to block the screen can pass through the screen surface smoothly. This form of vibration can greatly reduce the adhesion of materials to the screen surface, effectively prevent the blockage of the screen holes, and improve the screening efficiency and equipment operation stability.
When selecting the appropriate model, several key factors need to be considered, including the type of material to be processed, such as whether it is wet, viscous, or abrasive, the required throughput, particle size distribution, and installation conditions. Furthermore, the number of screen layers and screen size should be configured according to the required screening accuracy. Making a reasonable selection based on these parameters ensures optimal performance, improves operating efficiency, and reduces long-term maintenance costs.
Our factory produces both coarse and fine High Amplitude Vibrate Screens. The selection is based on the particle size of the material being processed. We also support non-standard customization, producing suitable screening machines tailored to your needs.

High amplitude vibrate screens are particularly suitable for screening coarse, heavy, or wet materials because they significantly improve material stratification, accelerate particle movement on the screen surface, thereby increasing overall screening efficiency and throughput while reducing the likelihood of clogging. Therefore, high-amplitude vibrating screens are especially suitable for industries requiring large-volume material handling, such as mining, aggregate and coal processing.
The main and auxiliary frames of the high-amplitude vibrating screen vibrate in opposite directions, causing the screen surface to relax.
High amplitude vibrating screens mostly use dual motor self-synchronous excitation or exciter drive structure, and achieve large-scale excitation through eccentric blocks or vibration boxes. It has the advantages of simple structure, easy maintenance, and low energy consumption. The screen structure can choose single-layer or multi-layer screens according to customer needs, supporting different uses such as multi-level classification, impurity removal and water removal. Common screen materials include high manganese steel woven mesh, polyurethane screen and stainless steel screen, which can be customized according to material characteristics to extend service life and improve screening quality.
Its core features are large amplitude and strong screening ability, which are suitable for large-capacity and high-efficiency material screening needs in industries such as coal, mining, metallurgy, building materials, electricity, and chemicals.
High amplitude vibrating screen is particularly suitable for coarse, medium and fine screening of difficult-to-screen materials such as wet coal, ore, washed materials, slag, and construction waste. It is also often used as a front or end screening equipment for crushing systems. For occasions with high requirements for grading particle size, strong material adhesion, and high production load, it can effectively solve the problems of easy blockage of traditional screens, incomplete screening, and frequent maintenance.

What is a high-amplitude vibrating screen?
A high-amplitude vibrating screen is a screening device with a large vibration amplitude. Driven by a motor, it generates strong vibrations, effectively handling coarse particles and heavy materials, reducing screen clogging. It is suitable for industries such as mining and building materials, and its core function is efficient screening of coarse and heavy materials.
What materials is it suitable for?
It is mainly suitable for coarse particles and heavy bulk materials such as ores, aggregates, coal, and sand. It can also be used for screening some materials that are prone to agglomeration and screen clogging.
What is the difference between a high-amplitude screen and a high-frequency screen?
A high-amplitude screen has a large amplitude and low frequency, handling coarse particles and heavy materials larger than 5mm, used for initial coarse processing. A high-frequency screen has a small amplitude and high frequency, handling fine particles and fine powder materials smaller than 5mm, focusing on fine classification, used for final fine processing.
Does a higher amplitude improve screening efficiency?
Yes, for coarse and heavy materials, a higher amplitude can improve material movement, break up agglomerates, and reduce clogging, thereby increasing screening efficiency. However, a higher amplitude is not always better. Excessive amplitude can reduce classification accuracy, accelerate equipment wear, and offers no advantage for fine particles. It is necessary to select an appropriate amplitude based on the material characteristics.
