QTJ4-26 Block Machine

The QTJ4-26 Block Machine is an efficient concrete block making machine designed for producing hollow blocks, solid blocks, and paver bricks. It adopts a combination of vibration and pressure forming technology to improve material compaction and maintain stable product dimensions and quality.

With a 25–30 second molding cycle, 4,500 r/min vibration frequency, and 14.25 kW total power, the QTJ4-26 is suitable for small- and medium-scale block production plants, construction material manufacturers, and building projects.

1. Technical Specifications

2. Production Capacity

The QTJ4-26 supports multiple mold configurations, allowing manufacturers to produce different concrete products according to market demand and construction requirements.

Actual production capacity may vary depending on raw material properties, concrete mix, mold configuration, operating conditions, and production environment.

3. Product Features

Vibration and Pressure Forming

The QTJ4-26 combines mechanical pressure and high-frequency vibration during the molding process. This helps distribute the concrete mixture evenly and improve compaction, resulting in concrete products with stable dimensions and consistent structure.

High-Frequency Vibration

The machine operates at a vibration frequency of 4,500 r/min, providing effective vibration during molding. Proper vibration helps improve material filling and compaction while supporting consistent product quality.

Fast Molding Cycle

With a molding cycle of approximately 25–30 seconds, the QTJ4-26 is designed for continuous production and improved manufacturing efficiency.

Flexible Mold Configuration

By changing the mold, the machine can produce various concrete products, including:

• Hollow concrete blocks
• Solid concrete blocks
• Paver bricks
• Other customized concrete products

This flexibility enables manufacturers to adjust production according to different orders and market requirements.

Compact Machine Structure

The machine has overall dimensions of 2060 × 1700 × 2280 mm, providing a compact and practical footprint for block production workshops and construction material plants.

Standard Pallet Size

The QTJ4-26 uses 880 × 480 mm pallets, providing a suitable base for freshly molded concrete products and subsequent handling and curing operations.

4. Hollow Block Production

For 400 × 200 × 200 mm hollow blocks, the QTJ4-26 produces 4 pieces per mold.

With a molding cycle of 25–30 seconds, the estimated production capacity reaches approximately 2,500–3,000 pieces per 8-hour shift.

This configuration is suitable for standard concrete hollow blocks commonly used in wall construction and masonry projects.

5. Solid Block Production

Using the appropriate mold, the QTJ4-26 can produce 240 × 115 × 53 mm solid blocks.

The mold produces 21 pieces per cycle, with an estimated production capacity of approximately 12,000–15,000 pieces per 8-hour shift.

This high output configuration makes the machine suitable for customers who require larger quantities of small solid concrete blocks.

6. Paver Brick Production

For paving applications, the machine can produce 200 × 160 × 60 mm paver bricks, with 8 pieces per mold.

The estimated production capacity is approximately 5,000–5,500 pieces per 8-hour shift, making it suitable for pedestrian areas, courtyards, landscaping projects, and other paving applications.

7. Applications

The QTJ4-26 Block Machine is suitable for producing concrete products used in:

• Residential construction
• Commercial construction
• Partition walls
• Masonry projects
• Road and pavement construction
• Landscaping projects
• Courtyards and walkways
• Construction material factories
• Small- and medium-scale block production plants

8. Key Advantages

High Production Efficiency

The 25–30 second molding cycle supports fast and continuous production.

Effective Compaction

The combination of 4,500 r/min vibration and pressure forming helps improve concrete compaction and product consistency.

Multiple Product Options

The machine can produce hollow blocks, solid blocks, paver bricks, and other concrete products by changing the mold.

High Solid Block Output

With the dedicated solid block mold, production can reach approximately 12,000–15,000 pieces per 8-hour shift.

Practical Machine Design

The compact dimensions and standard 880 × 480 mm pallet size make the machine suitable for a wide range of production environments.

Flexible Production

Different molds allow manufacturers to switch between products according to customer orders, construction requirements, and market demand. Even concrete blocks, apparently, benefit from having several career paths.
