QTJ4-35 Block Machine

The QTJ4-35 Block Machine is a compact and efficient concrete block making machine designed for producing hollow blocks, solid blocks, and paver bricks. It combines vibration and pressure forming technology to improve concrete compaction and achieve stable, uniform block shapes.

With a 25–30 second molding cycle, 4,500 r/min vibration frequency, and 11.25 kW total power, the QTJ4-35 provides a practical solution for small- and medium-scale concrete product manufacturers, construction material factories, and building projects.

1. Technical Specifications

2. Production Capacity

The QTJ4-35 supports multiple mold configurations for different concrete products. Production capacity varies according to the selected product, mold quantity, molding cycle, raw material characteristics, and operating conditions.

3. Product Features

Vibration and Pressure Forming

The QTJ4-35 uses a combination of high-frequency vibration and pressure forming. During molding, vibration helps distribute the concrete mixture evenly, while pressure improves compaction and shaping.

This forming method helps produce concrete products with stable dimensions, good density, and consistent appearance.

High-Frequency Vibration

With a vibration frequency of 4,500 r/min, the machine provides effective vibration during the forming process. Proper vibration helps reduce internal voids and improves concrete compaction.

Fast Molding Cycle

The machine features a molding cycle of approximately 25–30 seconds, allowing continuous production and helping manufacturers improve overall production efficiency.

Flexible Product Manufacturing

By changing the mold, the QTJ4-35 can manufacture a variety of concrete products, including:

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

This flexibility allows manufacturers to adjust production based on market demand and project requirements.

Compact Structure

The overall dimensions are 2060 × 1700 × 2280 mm, providing a practical footprint for production workshops and construction material plants.

Standard Pallet System

The QTJ4-35 is equipped with 880 × 480 mm pallets, providing a suitable working platform for freshly molded concrete products and subsequent handling.

4. Hollow Block Production

For 400 × 200 × 200 mm hollow blocks, the machine produces 4 pieces per mold.

With a molding cycle of approximately 25–30 seconds, the estimated production capacity is 2,200–2,500 pieces per 8-hour shift, depending on operating conditions and material quality.

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

5. Solid Block Production

Using the appropriate mold, the QTJ4-35 can produce 240 × 115 × 53 mm solid blocks.

The mold produces 21 pieces per cycle, with an estimated production capacity of 8,000–10,000 pieces per 8-hour shift.

This configuration is suitable for small masonry units and other concrete solid block applications.

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 output reaches approximately 4,000–4,500 pieces per 8-hour shift, making it suitable for walkways, courtyards, landscaping areas, and other paving projects.

7. Applications

The QTJ4-35 Block Machine can be used for manufacturing concrete products for:

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

8. Key Advantages

Efficient Production

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

Strong Compaction

The combination of 4,500 r/min vibration and pressure forming helps improve the density and consistency of finished concrete products.

Multiple Product Options

Different molds allow the same machine to produce hollow blocks, solid blocks, paver bricks, and other concrete products.

Practical Power Consumption

The machine has a total power requirement of 11.25 kW, providing a practical balance between production capability and energy consumption.

Compact Installation

The relatively compact dimensions make the machine suitable for production workshops with limited installation space.

Flexible Production

Manufacturers can switch molds according to different orders and market requirements, because apparently even concrete blocks need a little career flexibility.
