Built for Continuous Granite Production
The HLMJX series is designed around continuous production:
Slab Feeding → Profile Detection → Grinding → Fine Grinding → Polishing → Finished Slab
Multiple polishing heads work progressively through different stages, allowing the machine to distribute material removal and surface finishing across the line instead of depending on a single polishing operation.
This makes the system particularly suitable for granite factories, slab processors and manufacturers supplying large-volume construction and interior projects.
Consistent Finish Across Different Slabs
Photoelectric detection: Sensors at the feeding section detect slab thickness and surface profile before polishing.
PLC head control: Detected data is sent to the PLC, which controls individual polishing-head lifting and lowering.
Less wasted grinding: Heads avoid unnecessary grinding where no stone is present.
Edge protection: Reduced unnecessary contact helps protect slab edges from damage.
Stable continuous production: The process remains more consistent when slab conditions change.
Adjustable parameters: Conveyor speed and polishing settings can be adapted to different materials and finish requirements.
Choose the Number of Heads for Your Production Volume
The HLMJX series is available in 8, 12, 16, 20 and 24-head configurations.

Designed for Granite, Adaptable to Other Stone
Granite is the primary application – especially where consistent polished surface quality is required across production batches. The machine also processes marble, quartzite, engineered stone, travertine, onyx, terrazzo, and compatible stone products.
Different materials require different abrasives and processing parameters. We help you select the right configuration – Frankfurt abrasive blocks or resin grinding discs – according to your material and required finish.
Less Routine Maintenance During Continuous Operation
The HLMJX incorporates several features intended to reduce routine intervention:
Automatic Central Lubrication: Lubricant is distributed automatically to designated bearings, spindles and guide components at preset intervals.
Belt Cleaning System: The conveyor system includes automatic cleaning and stone-debris removal to help maintain stable slab transport.
Planetary Reducer Drive: The slab transport system uses planetary reducers for controlled and stable movement.
Quality Control Before Shipment
Before delivery, each polishing machine is checked against the confirmed configuration and undergoes factory testing.
Structural Inspection: Machine structure, conveyor system and major mechanical assemblies are inspected before commissioning.
Polishing Head Testing: Individual polishing heads are checked for movement, rotation and operating response.
PLC & Electrical Testing: The control system, touchscreen interface, sensors and electrical components are tested before shipment.
Conveyor Testing: The conveyor is operated continuously to verify stable slab transportation and belt tracking.
Test Run: The complete machine is run before final packing to identify abnormal vibration, control faults or mechanical issues.
FAQ
Q: What is the difference between an 8-head and a 24-head polishing machine?
A: The main difference is the number of sequential grinding and polishing stages available. More heads allow the production process to distribute grinding and polishing across more stages and are generally better suited to higher-volume production.
Q: Can the machine polish materials other than granite?
A: Yes. Depending on the abrasive and configuration, it can also process marble, quartzite, engineered stone, travertine, onyx and compatible stone products.
Q: What should I provide when requesting a quotation?
A: Please provide your stone type, slab thickness and width, required finish and expected production volume. This information allows us to recommend the appropriate number of polishing heads and machine configuration.
Q: What is the standard production lead time?
A: The standard production lead time is 30 days after receipt of the deposit. This covers machine manufacturing, assembly and factory testing before shipment. The confirmed delivery date is stated in the sales contract.
Q: What payment method do you accept?
A: For international orders, we accept T/T (Telegraphic Transfer). The required deposit and balance payment terms are specified in the quotation and sales contract before production begins.
Q: What shipping terms can you provide?
A: We support EXW, FOB and CIF trade terms for international orders. Buyers can choose the appropriate term according to their preferred shipping arrangement.
