Product Description
Ingeniously positioned above the sand conveying belt, this marvel breaks down green sand into a perfectly loose state post-mixing.
In the realm of green sand casting and mechanized sand recycling lines, this game-changing tool is vital. It expertly loosens mixed wet sand and crushes old sand post-separation, ensuring seamless docking with dust removal pipelines. The mechanized foundry sand recycling process is greatly influenced by the compaction of wet sand after mixing and agglomeration of old sand at the drop station, impacting the molding sand's permeability (>80cm³/min) and casting surface quality. As the powerhouse of sand processing, the sand loosening machine revolutionizes modern foundry workshops with its robust loosening, superior crushing, and intelligent dust removal. This exploration delves into how this machine propels foundries towards efficient sand resource regeneration and pristine production, by embracing technological breakthroughs, adapting processes, boosting environmental efficiency, and harnessing intelligent controls.
1. Process Pain Points and Technological Innovation
Challenging the compaction of wet sand (3-5% water) and the crushing demands of old sand (with core bone, iron impurities), this cutting-edge machine strides forward with dual-mode crushing prowess and modular ingenuity:
Wet Sand Loosening Mode:
Rotary Knife Crushing System: With 304 stainless steel staggered blades (HRC55-60 hardness) slicing sand blocks at a brisk 1200r/min, it delivers a processing might of 60t/h. The bulk density of freed molding sand is kept ≤1.4g/cm³, enhancing air permeability by an impressive 40%.
Dynamic Screening Module: Featuring a Φ8mm aperture grid, it synchronously segregates unbroken large particles (return rate <2%), ensuring uniformity for molding sand onto the conveyor belt (particle size standard deviation <0.15mm).
Old Sand Crushing Mode:
Hammer Impact Mechanism: With high manganese steel hammer heads (impact toughness ≥120J/cm²), it crushes old sand groups with iron beans (≤20mm diameter) at a 45t/h efficiency, boasting an iron impurity separation rate of over 98%.
Magnetic Pre-separation: A permanent magnetic roller (≥1500Gs magnetic induction strength) preemptively captures ferromagnetic impurities, curbing hammer head wear by a staggering 70%.
Intelligent Switching Technology:
Seamlessly toggle between wet and old sand modes with one-button PLC control; conversion in under 3 minutes, adaptable for intermittent or continuous production line setups.
2. Integrated Solution for Foundry Sand Processing Line
Harmonized operation among the loose sand machine, conveyor belt, and dust removal system cultivates a high-efficiency sand processing ecosystem:
Space Optimization Design:
Featuring an ingenious inverted installation, it elegantly perches above the B=800-1400mm belt conveyor, maintaining a net height ≤1.2m. This saves a notable 30% of the workshop's vertical space.
Standardized inlet and outlet flanges (ISO 5211) ensure a flawless connection with the sand mixer and old sand screening machine (±2mm connection error).
Easy Maintenance:
Quick-detachable cutter heads and hammer brackets make tool replacement a breeze, clocking in at under 20 minutes;
Observation windows and inspection doors, supported by gas springs, allow single-person daily maintenance with ease.
3. Core Advantages and Economic Benefits
The loose sand machine embodies a transformative leap in foundry sand processing, driven by innovative materials and intelligent control mechanisms:
Introducing our wear-resistant and exceptionally durable design:
The blade surface boasts a cutting-edge, laser-clad tungsten carbide coating, with a precise thickness of 0.3-0.5mm. This innovation remarkably multiplies the blade's lifespan by a staggering fourfold compared to conventional blades.
The box lining is ingeniously designed to be replaceable with a high-performance ARQ wear-resistant steel plate, boasting a formidable hardness rating of HB450. This strategic enhancement results in a remarkable 65% reduction in annual maintenance costs.
Revolutionizing energy consumption, we offer unparalleled optimization:
Equipped with a state-of-the-art 55kW permanent magnet synchronous motor, coupled with an advanced variable frequency drive system, our technology ensures a striking 25% reduction in electricity usage compared to traditional asynchronous motors.
Our efficient design boasts a power consumption rate for crushing 1 ton of molding sand at an impressive ≤0.8kW·h, slashing energy use by 40% when compared to traditional roller crushers.
Enhancing quality with precision-backed data:
Our sophisticated technology ensures the compaction rate of loosened sand remains stable with fluctuations of just ≤2%, while dramatically decreasing the porosity defect rate in castings from 3.8% to a mere 0.5%.
We achieve a remarkable old sand recycling rate of 95%, concurrently curtailing the need for new sand additions by an impressive 60%.
