QT12-15 Concrete Block Making Machine

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

1. Product Overview

The QT12-15 Concrete Block Making Machine is a high-efficiency hydraulic and vibration block forming machine designed for the production of various concrete masonry and paving products.

The machine combines hydraulic pressing, high-frequency vibration, automatic material feeding, and PLC intelligent control to achieve efficient forming, high product density, accurate dimensions, and consistent quality.

By changing molds, the QT12-15 can produce hollow blocks, perforated bricks, paving blocks, kerbstones, grass pavers, slope protection blocks, decorative blocks, and other concrete products.

2. Key Features

High-Efficiency Hydraulic Vibration Forming

The machine uses hydraulic pressure combined with vertical table vibration to rapidly compact concrete materials and produce dense, strong, and dimensionally accurate products.

Intelligent PLC Control

The PLC control system with touchscreen interface supports automatic and manual operation, production parameter adjustment, process data storage, fault indication, and machine status monitoring.

Strong and Durable Structure

The main frame adopts a heavy-duty gantry structure made from high-strength steel, providing excellent rigidity, vibration resistance, and long-term operating reliability.

Efficient Material Distribution

The special material storage and distribution system helps achieve fast and uniform feeding. The optimized vibration and feeding process improves product consistency and reduces production waste.

Wide Raw Material Compatibility

The machine can process a variety of materials, including cement, sand, crushed stone, fly ash, coal gangue, slag, steel slag, and other suitable industrial by-products, depending on the mix design.

Flexible Product Production

Different molds can be quickly installed to produce various block and paving products, allowing manufacturers to adapt production to different market requirements.

3. Main Technical Parameters

4. Typical Production Capacity

Actual production capacity depends on product specifications, raw materials, mix design, curing conditions, and operating parameters.

5. Main Equipment Components

The complete QT12-15 system mainly consists of:

• Block Forming Machine – performs material feeding, vibration, hydraulic pressing, forming, and demolding.

• Pallet Feeding Machine – stores and automatically feeds production pallets.

• Material Storage Hopper – stores mixed concrete and supplies material to the distribution system.

• Block Conveyor – transfers freshly formed blocks and pallets to the next production stage.

• Hydraulic Station – provides hydraulic power for the machine's moving components.

• PLC Electrical Control Cabinet – manages automatic production, parameter settings, machine status, and safety interlocks.

6. Products

With different molds, the QT12-15 can produce:

• Hollow Concrete Blocks

• Solid Concrete Blocks
