QMJ4-30 Block Making Machine

The QMJ4-30 Block Making Machine is a compact and efficient hydraulic concrete block machine designed for the production of hollow and solid concrete blocks in different sizes. With automatic material handling movement, hydraulic demolding, and mold vibration technology, the machine delivers stable performance, consistent block quality, and efficient production.

The QMJ4-30 is suitable for small- and medium-scale construction material manufacturers, block production plants, and building projects requiring a flexible and economical block-making solution.

Product Features

1. Flexible Block Production

The QMJ4-30 supports multiple mold configurations, allowing manufacturers to produce different block sizes according to market and construction requirements.

• 400 × 200 × 200 mm: 4 pieces per mold
• 400 × 150 × 200 mm: 5 pieces per mold
• 400 × 120 × 200 mm: 6 pieces per mold

2. Efficient Molding Cycle

The machine has a molding cycle of approximately 30–40 seconds, providing efficient and continuous block production.

3. Hydraulic Demolding System

The hydraulic demolding system helps improve demolding efficiency and ensures smooth removal of formed blocks, reducing the risk of damage during production.

4. Mold Vibration Technology

The QMJ4-30 uses a mold vibrating system with a vibration frequency of 4,500 rpm and an exciting force of 28.6 kN. The strong and uniform vibration helps distribute concrete material effectively and improve block density and forming quality.

5. Automatic Moving System

The machine adopts an automatic moving mode, reducing manual handling requirements and improving production efficiency.

6. Practical and Compact Design

With host machine dimensions of 1,300 × 1,500 × 1,100 mm and a machine weight of approximately 0.8 tons, the QMJ4-30 offers a compact footprint while maintaining stable production performance.

Production Capacity

The production output varies according to the selected block size and mold configuration:
