Product Description
Introducing the S33 Series Crusher, the brilliant fourth-generation marvel from Qingdao Sanzhuji Technology Co., Ltd. This all-inclusive powerhouse combines crushing, screening, and primary regeneration into a seamless unit. Compared to traditional built-in crushers, the S33 stands out with unmatched reliability, simplicity in design, and ease of maintenance, making it the go-to solution for modern foundry operations.
In the realm of foundry sand processing, the breakthrough S33 series crushers redefine industry standards with their exceptional crushing efficiency and impressive sand recovery rates. Specifically engineered for the regeneration of old sand blocks like furan resin and water glass sands, these crushers promise a remarkable recovery rate of 95%—all while minimizing maintenance costs. This comprehensive analysis will delve into the technical principles, core advantages, application scenarios, and the economic benefits that make the S33 a game-changer in sustainable sand processing.
1. Technical principles and core design breakthroughs
Harnessing the inherent physical properties of foundry sand blocks—hardness HB 80-120 and particle size Φ20-100mm—the S33 series expertly navigates technological advancements through its multi-dimensional crushing and regeneration system:
Fourth-order crushing and regeneration technology:
Primary Crushing Excellence: The high-frequency vibration motor, with an excitation force of 240-2100kN, propels the hammer to impact sand blocks. It offers an impressive processing capability of 5-20t/h, finely crushing sand to a particle size of ≤2.5mm. Ideal for addressing the hardness variations between furan resin and water glass sands.
Dynamic Precision Screening: Utilizing a robust double-layer stainless steel screen with apertures Φ5mm/Φ0.2mm, it efficiently segregates sand from impurities. Achieving a micro powder residual rate of less than 0.5%, it ensures the AFS particle size concentration (CU value) is maintained at ≤1.3.
Pre-regeneration Mastery: Employing a centrifugal friction plate with a linear speed of 6-8m/s, it adeptly removes residual resin films from sand surfaces, achieving a film removal rate greater than 2.5% while maintaining the regenerated sand's loss on ignition (LOI) at a stable 1.8-3.0%.
Intelligent Dynamic Control: A cutting-edge frequency converter adeptly adjusts the vibration frequency (15-50Hz) to ensure uniform crushing across various sand qualities, including silica and chromite sands.
Modular and compact design:
Space-Saving Innovation: The remarkably compact design occupies less than 5m³, optimizing space utilization by 40% compared to conventional crushers. A perfect fit for workshop modernization projects.
Effortless Maintenance: Featuring a quick-detachable hammer head and screen, which can be replaced in under 30 minutes, it enhances maintenance efficiency and slashes the average annual maintenance costs by a significant 60%.
Energy-saving and environmentally friendly features:
Eco-Efficient Power: The integration of a cutting-edge permanent magnet synchronous motor (23-27.5kW) with an energy feedback system ensures power consumption for sand processing remains ≤2.5kW·h per ton.
Advanced Dust Control: A meticulously sealed structure (leakage rate <3mg/m³) combined with a pulse dust collector (air volume 5000m³/h) ensures dust emission concentrations remain below 5mg/m³, promoting an eco-friendly operation.
2. Core advantages and industry value
Redefining Efficiency: The S33 series transcends the capabilities of traditional built-in crushers through strategic structural optimization and intelligent control, setting a new benchmark for industry excellence.
High Recovery and Efficiency Metrics:
Achieving a stellar sand recovery rate exceeding 95%, with a minimal crushing rate below 1.2%, the need for new sand replenishment is drastically reduced by 50%—a game-changer for cost-efficiency.
Refined Sand Quality: With a Roundness Index of regenerated sand at ≥0.82, air permeability sees a considerable boost of 35%, effectively lowering the porosity defect rate of castings to an impressive below 0.8%.
Comprehensive Process Adaptability:
Seamlessly integrate with vibrating sand-falling machines and magnetic separation equipment to construct a holistic sand processing ecosystem encompassing 'crushing-screening-regeneration-cooling';
Our cutting-edge technology is engineered for seamless compatibility with resin sand, water glass sand, V-method casting sand, and various other processes, ensuring an exceptionally stable demolding rate with fluctuations kept to an impressive ≤0.3%.
Unlock Significant Economic Benefits:
Consider this compelling example: A forward-thinking enterprise, with an annual casting output of 30,000 tons, can achieve remarkable savings by reducing their yearly new sand purchases by 1,500 tons. This smart move translates to an incredible cost saving of approximately 750,000 yuan; enhancing their profit margins substantially.
Experience the utmost in reliability and cost-efficiency with our equipment, boasting an exceptionally low failure rate of <0.5%. Enjoy the peace of mind with an annual average maintenance cost kept remarkably low at <20,000 yuan, and benefit from a swift investment return period of under 1.5 years.
