Product advantages

Advantage of QT12‑15F Fully‑automatic Brick Making Machine

1. Heavy‑duty Reinforced Frame for Anti‑deformation under Heavy‑load Operation

QT12‑15F main frame is welded by heavy‑duty 20×20cm square steel from Laigang and Jigang steel mill with stress‑relief treatment. Total machine weight reaches 12000 kg with sufficient structural rigidity for long‑time heavy‑load high‑frequency vibration. Universal drive shaft transmission replaces traditional direct‑driven motor structure to avoid frequent motor burnout and ensure smooth power transfer. Platform‑type table vibration distributes powerful exciting force evenly onto pallets, effectively preventing weld cracking and frame offset. It is perfectly suitable for non‑stop continuous mass production in large‑scale block factories.

2. Variable‑frequency Synchronous Vibration System: Low‑frequency Feeding & High‑frequency Forming for High Block Density

Equipped with variable‑frequency synchronous vibration unit with 110KN exciting force, adjustable vibration frequency ranges from 2800‑5100 times per minute. It adopts differentiated working logic: low‑frequency vibration during feeding phase to make raw material fully fill every corner of mold cavity; high‑intensity vibration during pressing‑forming phase to exhaust air bubbles thoroughly for uniform compaction across all green bricks on one pallet and lower reject rate. Vibration parameters can be customized for different raw materials and brick types for hollow blocks, solid bricks and color pavers. It achieves up to 25% energy‑saving compared with peer‑level heavy‑duty machines.

3. Germany Rexroth Hydraulic System with 21 MPa High‑pressure Stable Output

QT12‑15F adopts original Germany Rexroth hydraulic components with rated working pressure of 21 MPa to satisfy high‑pressure compaction requirement for multi‑cavity large‑size pallets. Independent external hydraulic power unit is isolated from host‑machine vibration and dust to reduce valve‑group contamination risk. Ferrule‑type pipe joints without welding minimize oil‑leakage risk. Under full‑load continuous multi‑shift production, stable oil pressure ensures gentle movement of pressing head, holding and demolding to prevent corner chipping and cavity collapse. Oil temperature monitoring, cooling and filtering assemblies maintain good hydraulic‑oil performance even under high‑temperature environment and cut downtime for large production lines.

4. Complete Siemens Electrical System with Built‑in Fault Diagnosis & Remote Monitoring

Core electrical components and touch‑screen HMI are all Siemens brand. PLC‑HMI realizes fully integrated mechanical‑hydraulic‑electrical coordinated control. Pre‑vibration duration, main‑vibration frequency, holding pressure and feeding cycles are adjustable on touch‑screen. Process profiles for various brick types can be saved and one‑click‑recalled for quick product change‑over. Complete electrical interlock prevents mechanical collision caused by mis‑operation. On‑board fault diagnosis displays error codes directly on screen. Reserved remote‑monitoring interface supports remote status viewing, troubleshooting and parameter adjustment. Operators can master production supervision after short‑term training without senior electrician on‑site.

5. Large‑size Multi‑cavity Pallet, Compatible with Color‑facing System for Wide Product Range

Large pallet dimension reaches 1420×900 mm with multi‑cavity layout for high hourly output, molding cycle 15‑25 seconds. The machine can match lifting‑traveling color‑facing feeder to realize separate base‑material and color‑surface feeding for double‑layer colored paving blocks. By replacing carburized manganese‑steel molds processed by wire‑cutting, users can produce hollow blocks, solid standard bricks, interlocking blocks, grass‑planting blocks, slope‑protection blocks and curbstones. Wearing mold parts can be replaced separately instead of whole‑mold replacement to lower consumable cost for large‑scale production lines. QT12‑15F Fully‑automatic Brick Production Line

6. Wide Raw‑material Compatibility for High‑efficiency Solid‑waste Recycling

QT12‑15F supports diversified raw materials: sand, stone powder and cement as main ingredients. Large proportion of industrial residues such as fly ash, furnace slag, coal gangue and expanded perlite can be utilized for brick‑making. Special storage and feeding mechanism isolates foreign impurities and guarantees feeding accuracy. Properly proportioned mixtures reduce cement consumption while meeting finished‑product strength requirements. Making full use of local industrial waste complies with solid‑waste recycling policies and cuts raw‑material procurement cost for large block plants under diverse regional material conditions.

7. Seamless Matching for Full‑automatic Production Line, Complete Project Delivery & After‑sales Support

This main machine can perfectly connect with PLD1200 batching machine, JS750 twin‑shaft mixer, 8‑meter double‑layer belt conveyor, automatic block stacker and pallet elevator to build a complete large‑scale automatic block production line. Modular split packaging facilitates sea container transportation. After on‑site positioning, leveling, wiring and piping, no‑load joint commissioning can be performed for trial‑production. Manufacturer provides reference mixing ratios, mold‑installation guidance and troubleshooting instructions for common brick defects. One‑year full‑machine warranty is offered. Original spare parts including hydraulic kits, electrical parts and complete mold sets are continuously supplied to secure long‑term stable running of large‑capacity production lines.
