Find answers to common questions about hollow block making machines, production, pricing, and after-sales support.
A hollow block making machine is specialized equipment designed to produce hollow concrete blocks used in construction. It uses vibration and hydraulic pressure to mold materials like cement, sand, fly ash, and aggregates into hollow blocks with voids that reduce weight and material cost while maintaining structural strength. These machines come in manual, semi-automatic, and fully automatic configurations to suit different production scales.
The price of a hollow block making machine ranges from $1,000 for manual mobile models like the QMJ2-40 to $50,000+ for fully automatic production lines like the QT8-15. Factors affecting price include automation level, production capacity, mold configuration, and brand. Wojin Machinery offers factory-direct pricing that saves you up to 40% compared to trading companies. Contact us for a detailed quote tailored to your specific requirements.
Hollow blocks are made from cement, sand, crushed stone, fly ash, slag, cinder, and water. The typical mix ratio is 1 part cement to 4-6 parts aggregate. Fly ash and slag can partially replace cement to reduce costs while maintaining quality. All materials should be locally available, making production economical. Our machines are compatible with various material compositions and can be adjusted for optimal block strength.
Production capacity varies by model. Manual machines like QMJ2-40 produce about 1,280 blocks per 8 hours. Semi-automatic models like QT4-25 produce 4,500-5,248 blocks per 8 hours. Fully automatic models like QT8-15 can produce over 120,000 blocks per 8-hour shift. Capacity depends on block size, material mix, and operator proficiency. We can help you select the right model based on your daily production targets.
