Hyperstatic Vibrating Screen

I. Patented Product: Legal Safeguard and Performance Endorsement of Cutting-edge Technology  

This product holds a national invention patent, with its core innovations having been confirmed through intellectual property rights. The patent-protected statically indeterminate mesh beam device adopts a composite structure of "multiple main beams + statically indeterminate support plates," eliminating the need for traditional I-beam supports. This reduces the exciter’s volume by over 30%, lowers the vibrating mass by 25%, and increases the excitation force transmission efficiency to over 90%. This patented technology not only avoids the risk of structural plagiarism but also, as verified by finite element analysis, ensures that under a working frequency of 12.2 Hz, the maximum stress on the screen body is only 15.495 MPa—far below the 30 MPa threshold of traditional structures—providing dual assurance in both legal and data terms for the equipment’s long-term stable operation.  

II. Domestic First: Industry Breakthrough Breaking Technological Monopoly  

As the first statically indeterminate mesh beam excitation vibrating screen in China to achieve industrial application, its technical approach fills the gap in large-scale domestic vibrating screens. Compared to traditional single-channel/dual-channel structures, this product introduces, for the first time, the theory of statically indeterminate structures from theconstruction field into screening equipment. Through "redundant constraint design," the screen body maintains geometric stability even if a single constraint is compromised, enhancing its resistance to sudden damage by over 40%.  

III. New Mesh Beam System Structure: Reconstructing the Performance Foundation of Large Screens  

1. Structural Design Innovation  

Adopting a coupled structure of "6 tube beams + 2 exciter beams + statically indeterminate support plates," it forms a high-rigidity inclusive excitation element. The lateral rigidity is increased by 30% compared to traditional dual-channel structures, solving the challenge of "insufficient rigidity caused by width expansion" in large screens. By adding baffle plates and peripheral reinforcing ribs, the lateral deformation of the screen body is reduced from 0.428 mm to 0.126 mm, achieving top-tier industry precision in deformation control.  

2. Dynamic Performance Optimization  

The natural frequency, optimized through modal analysis, is kept far from the 12.2 Hz working frequency, completely avoiding resonance risks and reducing the equipment failure rate by over 60%. Compared to single-channel structures, its bending-torsion deformation natural frequency is increased by 50%, maintaining vibration stability even in large models with a 3.6 m screen width, with noise controlled below 85 dB.  

IV. Imported Product Alternative: Dual Superiority in Cost-performance and Adaptability  

1. Technical Specifications Aligned with International Standards  

It achieves "catch-up and surpassing" of imported equipment in core performance: screening efficiency reaches 90% (typically 85%-88% for imported equipment), service life exceeds 5 years (around 4-5 years for imported equipment), while the price is only half that of similar imported products.  

2. Localization Adaptation Advantages  

Tailored to the characteristics of high-ash and high-viscosity raw coal in China, the excitation parameters and screen inclination angle are optimized, reducing hole-blocking rates to below 5% (typically 10%-15% for imported equipment). Meanwhile, spare parts supply cycles are shortened to 7-15 days, far better than the 3-6 months of imported equipment, and maintenance costs are reduced by over 40%.  

V. Large Vibrating Screens: Key Equipment Solving Industry Expansion Challenges  

1. Specification Breakthrough and Capacity Upgrade  

It enables large-scale designs with a screen width of 3.0-3.6 m and a screen surface area of over 21.6 m², with a single-unit processing capacity increased by 30%-50% compared to traditional equipment, meeting the raw coal classification needs of large mines with annual outputs of over 12 million tons. By adopting a multi-exciter series connection, it solves the issue of "insufficient excitation force due to large-scale design," achieving an excitation intensity of 5.0 g to meet the stringent requirements of dry deep screening.  

2. Structural Reliability Assurance  

Through the stress dispersion design of the statically indeterminate mesh beam structure, the peak stress on the screen body during full-load operation is reduced by 20%, completely resolving the common issues of "tube beam fractures and side plate cracks" in traditional large screens. Application data from coal preparation plants in multiple provinces, such as Yunnan and Shanxi, show that the equipment operates continuously without failure for over 8,000 hours—far exceeding the industry average standard of 5,000 hours.
