Product advantages

Advantage of QT6‑15B Automatic Concrete Brick Making Machine

1. Integrated Mechanical‑Hydraulic‑Electrical Intelligent Control System for Safe & Easy Operation

The machine integrates mechanical structure, hydraulic components, PLC programmable controller and touch‑screen HMI. It supports both manual and automatic operation modes. Process parameters can be input, saved and recalled for flexible human‑machine interaction. Built‑in safety interlock logic and fault diagnosis functions prevent collision damage caused by mis‑operation. Complete functions including emergency stop, pause and home‑position reset protect operators and equipment. Reliable earthing is implemented for all electrical components. Operators can master daily operation after simple training.

2. Step‑by‑Step Vibration‑Press Molding for Superior Product Quality

Equipped with table vibration system, the vibration frequency reaches 4500‑5100 times per minute with vibration acceleration of 15‑20g. Combined with hydraulic pressing, finished blocks can achieve compressive strength above 15MPa. Step‑vibration ensures even material distribution. Produced blocks feature high density, good frost‑resistance, impermeability, sound and heat insulation, precise dimension, high consistency and low reject rate. Three‑layer rubber spring vibration‑isolation structure reduces resonance and noise, extending service life of spare parts.

3. Wide Raw‑material Compatibility for High Solid‑waste Utilization & Cost Control

This machine accepts diversified raw materials. Besides sand, stone and cement, it can make full use of industrial residues such as fly ash, furnace slag and coal gangue. Cement consumption can be properly reduced without sacrificing product quality, complying with solid‑waste recycling policies. Coarse aggregate shall be limited within 10 mm, so local materials can be adopted to cut raw‑material cost. Optional facing material feeder enables production of colored layered paving bricks, grass‑planting bricks and other decorative concrete products.

4. Multi‑function with Convenient Mold Replacement for Strong Market Adaptability

By simply changing molds, one single machine can produce hollow blocks, standard bricks, perforated bricks, curbstones, slope‑protection bricks and grass‑planting bricks for building walls, municipal roads, river bank restoration and landscape projects. Customers do not need multiple sets of equipment to diversify product ranges. After mold replacement, gaps between pressing head and mold box can be quickly adjusted for fast commissioning to meet various market orders.

5. Independent Integrated Hydraulic Station for Stable & Reliable Performance

The separate integrated hydraulic power unit avoids vibration and dust pollution from main machine, greatly improving hydraulic reliability. Rated system pressure is 16 MPa. N32 or N46 anti‑wear hydraulic oil is applicable. Suction‑oil and return‑oil filters plus oil cooler keep oil temperature within reasonable range and reduce hydraulic failures such as oil leakage and valve jamming. Hydraulic valves are pre‑calibrated before delivery, requiring only minor on‑site adjustment with clear maintenance procedures for technicians.

6. Robust Structure, Easy Maintenance & High Production Efficiency

Heavy‑duty frame and four‑column guiding mechanism guarantee accurate movement of pressing head and mold box. Wearing parts such as sliding sleeves and pin shafts can be replaced separately. Lubrication points are clearly defined for regular grease filling to reduce abrasion. Troubleshooting guidelines for material feeder, vibration box and guiding assembly are provided for on‑site maintenance. Total installed power is 26.25 kW. Molding cycle is 15‑25 seconds. Hourly output reaches 1080 pcs for hollow blocks and 6800 pcs for standard bricks. Pallet dimension is 850×680×30 mm, suitable for continuous mass production for medium‑small block factories.

7. Modular Split‑type Design for Simple Installation and Complete After‑sales Service

The whole machine is split into five modules: main forming host, pallet feeder, block conveyor, hydraulic station and electric cabinet for convenient transportation. After positioning, leveling, pipeline & wiring connection, operators can run no‑load manual and automatic test before formal production. The supplier provides on‑site installation, commissioning and operator training, together with reference raw‑material mix proportion. Under proper operation and maintenance, free repair and replacement are available for manufacturing defects within half‑year after delivery. Original molds and wearing spare parts are continuously supplied to lower customer's operation cost.
