Granite Polishing Machine Line (Resin Disc Type)

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

This continuous granite polishing line is a fully automated, high-efficiency solution engineered for stone processing factories and slab producers. Equipped with high-performance resin grinding discs, it transforms rough-cut granite slabs into mirror-finished, premium-quality surfaces in a single pass, delivering consistent results, maximum yield, and significant labor savings for large-scale production.

1.Resin Disc Polishing for Superior Surface Quality

The multi-stage resin disc grinding system delivers a uniform, high-gloss mirror finish across the entire slab surface, eliminating manual polishing inconsistencies. It ensures flat, scratch-free surfaces with excellent light reflection, directly increasing the market value of finished slabs and reducing rework costs.

2.Fully Automated Continuous Production

The conveyor-driven line operates at an adjustable speed of 0–4m/min, processing slabs continuously from rough grinding to final polishing. This eliminates manual handling between stages, boosting production efficiency by 80%+ compared to manual or semi-automated methods, and reducing reliance on skilled labor.

3.Intelligent Process Control & Monitoring

Integrated with a user-friendly HMI (human-machine interface) and a plate shape monitoring device, the system automatically adjusts grinding pressure and speed to maintain consistent slab flatness and finish quality. It also features automatic lubrication, centralized electrical control, and a cleaning brush system for stable, low-maintenance operation.

4.Robust, Industrial-Grade Construction

The heavy-duty frame, high-torque motor units, and precision reduction gears ensure stable, vibration-free operation even under 24/7 production loads. Each polishing head delivers 7.5kW of consistent power, ensuring uniform grinding across the full 1300mm working width, suitable for granite slabs of 10–60mm thickness.

5.Scalable for All Production Volumes

Available in 12-head, 16-head, and 20-head configurations, the line scales to match your production capacity:

1. ZDMJ-12D: Ideal for small-to-medium factories with moderate output requirements
2. ZDMJ-16D: The balanced, high-volume workhorse for most standard production lines
3. ZDMJ-20D: Maximum capacity for large-scale factories and export-grade slab production

This granite polishing line is a critical investment for stone processors looking to scale production, improve product quality, and reduce operational costs. It automates the entire polishing process, delivers consistent premium finishes, and maximizes material yield, delivering a fast return on investment through increased output and reduced labor overhead.
