QT8-15 Block Making Machine

High Efficiency · Hydraulic Vibration · Intelligent PLC Control · Multi-Product Capability

1. Product Overview

The QT8-15 Block Making Machine is a fully integrated mechanical, hydraulic, vibration, and PLC-controlled concrete block machine designed for the efficient production of high-quality concrete masonry products.

The machine uses hydraulic pressure combined with mechanical vibration to form dense and dimensionally accurate products. With a robust structure, high automation, and flexible mold configuration, it is suitable for producing a wide range of concrete blocks and paving products.

2. Key Features

High-Strength Block Production

Hydraulic pressing and high-frequency vibration provide excellent compaction, producing dense concrete products with compressive strength of up to 15 MPa or higher, depending on raw materials and production conditions.

Intelligent PLC Control

The machine is equipped with a PLC automatic control system and touchscreen interface. Production parameters can be stored and recalled, while automatic interlocking and fault monitoring improve operational safety and production consistency.

Reliable Hydraulic System

An independent hydraulic station reduces the influence of vibration and dust on hydraulic components, helping ensure stable and reliable operation.

High Material Adaptability

The machine can use different concrete raw materials, including aggregates, sand, cement, fly ash, and selected industrial waste materials, helping manufacturers optimize local material resources.

Flexible Mold Configuration

By changing molds, the machine can quickly switch between different products and specifications to meet changing market requirements.

3. Main Specifications

Typical Production Capacity

Actual output depends on product specifications, mix design, material conditions, and operating parameters.

4. Main Products

With different molds, the QT8-15 can produce:

• Hollow Concrete Blocks

• Solid Blocks

• Perforated Bricks

• Paving Blocks

• Kerbstones

• Grass Pavers

• Slope Protection Blocks

• Interlocking Pavers

• Other Customized Concrete Products

5. Production Process

Raw Material Mixing → Automatic Feeding → Material Distribution → Vibration & Hydraulic Pressing → Demolding → Block Transfer → Curing → Finished Products

The production parameters can be adjusted according to different block types, materials, and strength requirements.

6. Application

The QT8-15 is suitable for:

• Block manufacturing plants

• Paving block factories

• Construction material manufacturers

• Municipal infrastructure projects

• Road and pavement projects
