Pencil lead three roll grinder

Working principle of pencil lead special three roll grinder:

The three roll grinder achieves grinding effect by squeezing and rubbing the surfaces of three horizontal rollers at different speeds.

1. The roller material of the three roll grinder is centrifugally cast from cold hard alloy cast iron, with a surface hardness of HS70 or above. It is a high-strength and wear-resistant grinding machine, with strong toughness that is not affected by external pressure and temperature on the roller properties.

2. The roller diameter undergoes high-precision grinding, which is precise and delicate, and can achieve a grinding fineness of less than 5um for materials, producing uniform and delicate high-quality products.

3. The transmission system of the three roll grinder has added a reducer, which increases the output torque and has high transmission efficiency, smooth operation, and no noise. The parallel handwheel screw adjusts the roller distance, which is simple, accurate, and easy to operate

4. Adjusting the particle size of the ground material by adjusting the gap between the rollers through the parallel handwheel screw is simple, accurate, and easy to operate.

5. The three roll grinder is equipped with a cooling device that can dissipate the heat generated during the operation of the rollers, ensuring continuous operation; Suitable for multiple varieties and easy to change colors.

Maintenance and upkeep of pencil lead special three roll grinder:

Maintenance of Three Roll Grinding Machine: After six months of continuous use, it is recommended to conduct a major overhaul of the three roll machine. The washing parts should be disassembled and cleaned, replaced with clean lubricating oil, and the smoothness of the oil circuit should be carefully checked. If any problems are found during disassembly and cleaning, they should be repaired in a timely manner. If the roller is found to be deformed during use, it must be stopped and re ground. If the number of roller grinding cycles is too high and the diameter of the roller is smaller than the requirement, it will cause the transmission gear to tighten and leave gaps between the rollers. At this time, the gears must be corrected.

The sharp edge of the discharge blade should be carefully corrected and polished before installation, with no burrs or cracks allowed. After the blade is short, the countersunk screw can be loosened and removed outward before use.
