Advantages of QT4-30

 

Why Choose QT4-30 Production Line?
Smart & Compact: Paired with JQ350 mixer and 8m conveyor for a space-saving, continuous-production compact line.
Fast & Productive: 30s cycle (up to 3,840 blocks/day); 28 KN vibration system ensures high density and strength.
Profitable & Reliable: Only 2-3 operators and 11.6 kW power needed, cutting labor/energy costs for fast ROI in small/medium factories.

 

Powerful & Reliable Motor System

High Efficiency
It adopts a "table vibration + pressure head vibration" dual-vibration mode, ensuring the block compactness exceeds 95% and the strength meets the GB/T 8239 standard.

The QT4-30 delivers stable power for continuous production. Dual 3 kW vibration motors and a 1.5 kW upper vibrator generate up to 28 kN excitation force, ensuring strong compaction and consistent block quality.

Energy-Saving Performance
Optimized motor design reduces energy consumption by 15-20% compared with traditional models, lowering operating costs while maintaining high productivity.

Raw material better in adaptability

Vibration-feeding tech integration enables unique resource utilization.

QTJ4-35 block making machine processes various materials:

fly ash, coal gangue slag, steel slag, volcanic pumice, tailings sand, sand-gravel, construction waste, concrete fragments, etc.

 

Molds - Durability, Precision, Flexibility

Ultra-Long Life
High-chromium alloy steel (HRC60-62) with laser hardening: 3x wear resistance, 50% longer life than conventional molds.

Guaranteed Precision
CNC tolerance ±0.02mm; brick dimension error ≤0.5mm; finished product pass rate ≥99.2%.

Rapid Changeover
Quick-lock clamping + PLC recipes; supports 50+ brick types, 10-minute changeovers for better flexibility.

150,000 pressing cycles
With over 150,000 pressing cycles, this durability significantly reduces downtime and replacement costs.
