Product Features

  • Special Grinding Brush Design

One of the key features of our Volcanic ash grinding machine is its special grinding brush structure. This design allows for quick and easy replacement of any grinding brush within 5 minutes, without the need for professional adjustments. The machine comes equipped with a dedicated brush removal tool and a fixed position to facilitate the process. This feature significantly reduces downtime, ensuring smooth operation.

  • Efficient Grinding Program with Italian SEW Motor

JuYongNeng Volcanic ash grinding machine utilizes a special program design that is seamlessly integrated with an Italian SEW motor. This combination offers three different grinding functions: thin, medium, and thick. The thickness range extends from 0.2MM to 3.2MM, and for specific customer requirements, a model capable of producing plates as thick as 10MM has been developed. This feature makes the machine versatile for a range of grinding applications.

  • High Precision with Clutches and Encoders

It is equipped with clutches and high-speed encoders that work together to accurately calculate the plate length and position during machine operation. Additionally, it features German SEW brake motors to ensure prompt braking and smooth transitions in both forward and reverse control programs. This ensures precise handling and performance consistency during the grinding process.

  • Innovative Water Supply and Grinding Effect

To ensure smooth operation, our volcanic ash grinder has a reasonably designed water supply tank that works in tandem with the grinding brush. This setup ensures the supply of ash under the grinding brush, allowing plates with a thickness as low as 0.2MM to pass through while maintaining an effective grinding result. This design enhances the machine's capability to deliver excellent results on thin plates.

  • Comprehensive Sealing Structure

Our PCB pre-processing machine features a 5-layer sealing structure, combining inner and outer casing seals with additional sealing baffles and rings. This structure ensures optimal protection and efficiency during the grinding process, reducing wear and preventing external contamination, thereby enhancing the longevity and performance of the machine.

  • Smooth Transportation with Rubber Pressure Chain

The conveyor bag rubber pressure chain in the volcanic ash grinding machine is designed for easy disassembly and tight installation. It incorporates a semicircular quick disassembly type, combined with a complete 6-axis shaft core, ensuring smooth and reliable transportation of plates during grinding operations.
