What is a High-Frequency Resonant Crusher

The High-Frequency Resonant Crusher is a technology that, based on the principle of resonance, causes the concrete pavement and the high-frequency resonant crusher to resonate, thereby breaking the concrete pavement into an upper and lower layer of interlocking concrete aggregate particles. The shape of the aggregates complements each other, with small particle sizes, forming a stable structure through mutual compaction. The high-frequency resonant crusher solves the horizontal and vertical displacement issues at the cracks and joints of the original concrete pavement, eliminating the stress that reflects upward from the cracks in the original slab. This layer offers both strength and rigidity, similar to graded aggregate, and has a minimal impact on the old highway foundation, making it an effective solution to the problem of reflective cracks commonly encountered in concrete pavement installations. Resonant crushing technology for old concrete pavements mainly consists of three main parts: the resonant hammer head for crushing concrete roads, the reinforcement and stabilization of the crushed aggregate structure, and the precise design of pavement installation. Now, let's understand what a high-frequency resonant crusher is.

The High-Frequency Resonant Crusher is a specialized equipment for the resonance crushing technology. This unique resonance technology continuously generates high-frequency, low-amplitude energy, which is transferred from the crushing hammer head to the cement concrete slab to produce vibration harmonics. Under high-frequency and low-vibration conditions, the vibration hammer head performs small-energy crushing, creating uniform cracks within the pavement layer. The method of rapid, regular resonance crushing through vibration is superior to simple crushing and breaking. The High-Frequency Resonant Crusher utilizes a vibrating body to detect the working hammer, making the hammer's vibration frequency approximate to the inherent vibration frequency of the concrete panel through contact with the road surface. This causes the concrete panel to resonate locally under the hammer, rapidly reducing the internal friction resistance between the particles within the concrete, causing it to collapse. The inherent vibration frequency of the concrete panel varies with material and thickness, typically ranging from 40-70Hz.

The High-Frequency Resonant Crusher's Operating Parameters: Operating Frequency: 40-70Hz Working Amplitude: 10-20mm Crushing Thickness: Full depth of a single cement board (current practice depth is 40cm) Work Efficiency: 33602000-3000-3000 per day Vehicle Dimensions: 8000mm x 2800mm x 3100mm Vehicle Weight: 35 tons Computerized automatic frequency adjustment and force variation control stone size and breakage extent Unique Advantages of the High-Frequency Resonant Crusher: GP60 can crush fully and multifacetedly, right up to the roadside, leaving no sharp edges and requiring no additional auxiliary equipment for crushing. The standard frequency of GP60 can reach 70Hz or higher, adapting to different road conditions and providing excellent crushing results. Its effectiveness is mainly reflected in the even and dense crushing thickness of the upper surface layer, which is easy to bond board by board, and the lower layer has more extensive and dense cracks. Low failure rate, with a 20% increase in production efficiency compared to similar equipment.
