Granite Polishing Machine Line (Resin Grinding Disc)

ZDMJ-12D / ZDMJ-16D / ZDMJ-20D

Designed for large-scale stone processing factories, the ZDMJ Series Granite Polishing Machine Line is a continuous, high-efficiency finishing solution equipped with professional resin grinding discs. It delivers precise mirror polishing for hard stones such as granite and engineered stone, serving as the core equipment to boost slab gloss, enhance product added value, and maximize production efficiency.

1. Boost Production Efficiency & Throughput

• Multi-Head Synchronous Polishing: Available in 12/16/20-head configurations, the machine enables continuous slab feeding and polishing, drastically outperforming traditional single-unit polishing in output per shift.
• Wide Compatibility: Processes slabs up to 1300mm in width and 10–60mm in thickness, covering all mainstream engineering slab specifications without frequent setup changes.
• Adjustable Conveyor Speed: 0–4m/min infinitely variable speed allows flexible adjustment to match stone hardness and polishing requirements, balancing speed and finish quality.

2. High-Precision Polishing for Premium Product Value

• Professional Resin Disc Design: Granite-specific grinding heads paired with resin discs produce a high-gloss, clear-textured mirror finish, significantly increasing market price and competitiveness.
• Plate Shape Monitoring & Stable Conveying: A plate shape monitoring device ensures flatness, while a stable conveying system eliminates uneven polishing, missed spots, or over-polishing, raising yield by over 10%.
• Uniform Grinding Force Distribution: Precision reduction gears and motor units control grinding head pressure evenly, guaranteeing consistent polishing across every slab and minimizing color variation and surface defects.

3. Reliable Operation & Low Maintenance Costs

• Automatic Lubrication System: Automatically lubricates key moving parts to reduce wear, extend service life, and cut down on daily maintenance labor and frequency.
• Modular Electrical Control: PLC + HMI interface provides visual parameter adjustment, fault alerts, and diagnostic functions for quick troubleshooting and minimal downtime.
• Heavy-Duty Construction: With a total weight of up to 17,000kg, the robust frame ensures low-vibration operation, supporting 24/7 continuous production with a 25% lower failure rate than lightweight models.

4. Energy-Saving & Eco-Friendly Compliance 

• Optimized Water & Power Configuration: Water consumption is only 15–18m³/h, paired with automatic cleaning brushes to reduce water waste while maintaining polishing performance.
• Efficient Motor Units: 7.5kW per grinding head, with total power matched to capacity (106/135/165kW), avoiding redundant energy consumption and meeting factory energy-saving targets.
• Environmentally Friendly Operation: Enclosed structure and water circulation system effectively control dust and wastewater discharge, complying with global environmental production standards.

• Small/Medium Factories / Start-Up Phase: ZDMJ-12D – 12-head configuration, 106kW total power, compact footprint, and low initial investment, ideal for small-batch orders.
• Medium Factories / Stable Production Demand: ZDMJ-16D – 16-head configuration balances efficiency and cost, suitable for regular engineering and export orders.
• Large Factories / High-Volume Demand: ZDMJ-20D – 20-head full configuration, designed for large-scale continuous production to quickly fulfill major projects and export orders.

• Customization: Tailored solutions for voltage, factory layout, conveyor speed, grinding head configuration, and control language to meet regional standards.
• Global Service Network: On-site installation, commissioning, and operator training, plus 24/7 remote technical support to ensure smooth production startup.
• Spare Parts Supply: Global warehousing of core wear parts (grinding discs, motors, bearings) guarantees fast response to spare parts requests, minimizing costly downtime.
