QT15-15 big automatic concrete hollow block paver brick curb stone making machine in China block machine factory
Advantage :
QT5-15 brick making machine Adopting synchronization vibration insures the products making average. The frequency can change according to different technics. Low frequency in feeding material, high frequency vibration makes the different material to have a optimal vibration way.
The entire frame is made of Q355B high-quality steel!!!!
1) 4mm guide pillar ensure more stable
2) High pressure oil pump, bouble proportional valve.
3) PLC control and electrical components with SIEMENS brand, good quality
4) Lower frequency feeding material, high frequency vibration, block with high density

Benefits of PLC Control for Brick Machines:
1. Automation: Quick parameter switching, less manual work.
2. Precision: Accurate pressure/time control for consistent quality.
3. Efficiency: Optimized process saves energy.
4. Smart Maintenance: Self-diagnosis reduces downtime.
5. Easy Operation: Touchscreen interface, optional remote monitoring.
Benefits of the Circular Belt
1. Even Distribution: 360° rotation ensures uniform material spread for consistent brick quality.
2. Automation: Reduces manual feeding, boosting efficiency.
3. Clog-Resistant: Handles sticky or granular materials without blockages.
4. Compact Design: Saves space, easy maintenance.
5. Adjustable Speed: Adapts to different materials and brick types.
Key Selling Points of Circular Belt
1. Durability - Made of wear-resistant rubber/polyurethane for long service life.
2. Precision Control - Servo motor/frequency converter allows adjustable speed.
3. Proven Results - Increases brick quality (e.g., 90% → 98% pass rate).
4. Cost Savings - Reduces labor and waste for quick ROI (e.g., 3-month payback).
5. After-Sales - 1-year warranty + 24/7 technical support.
Benefits of Hydraulic Systems for Brick Machines
1. High-Pressure Precision
Delivers 200-300T steady pressure (3× mechanical presses) for uniform density (+25% strength).
Proportional valves adjust pressure curves for special bricks (permeable/paving).
2. Energy Saving
Variable pumps + accumulators cut power use by 40% (saves ¥80-120/shift).
Auto pressure relief at idle.
3. Low Maintenance
Reduces mechanical shock, extending mold life 2-3 years.
Oil temp/filtration alerts slash yearly costs by 60%.
4. Smart Control
Dual pressure/displacement sensors (≤0.3mm error).
PLC stores 100+ recipes, mold change in 5 mins.
5. ROI Case
Henan client: Maintenance ¥0.03/block (vs. ¥0.08 mechanical).
Paid back upgrade in 8 months.
Key Facts About Hydraulic Stations
1. Main Components
Power Unit: Motor + Pump (Gear/Piston)
Control Elements: Directional/Relief/Proportional Valves
Accessories: Oil Tank, Filter, Cooler
2 .Oil Lines:
2 main lines: High-pressure (red) & return (blue)
3-4 control lines: Mold lift/feeder/ejection
3. Proportional Valves:
(1) Main pressure - 3-stage pressing control
(2) Speed - mold movement adjustment
(3) Sync (optional) - multi-cylinder coordination
4. Safety:
Relief valve (26MPa max)
Manual emergency release
5. Maintenance:
Monthly pipe checks
Valve adjustments via PLC only
Never reverse main lines
Feeding Methods
1. Vibration Feeding
Uses vibrators to spread fine materials (e.g., fly ash)
Best for: Standard bricks
2. Belt Feeding (Rotary Distributor)
Rotating belt ensures even distribution
Best for: Coarse materials (construction waste)
3. Scraper Feeding
Adjustable scraper controls thickness (±1mm precision)
Best for: Permeable bricks
4. Screw Mixing Feeder
Mixes while feeding (prevents clumping)
Best for: Fiber-reinforced bricks
5. Hybrid System
Combines vibration + belt/scraper
Best for: Complex materials
Key Advantages
1. Uniform Distribution
Reduces defects (density variations)
2. Wide Compatibility
Handles powders, aggregates & recycled materials
3. Automation
PLC-controlled, minimal manual intervention
4. Anti-Clog Design
Reliable for sticky/coarse mixes
5. Easy Maintenance
