Have you seen this big guy? Its name is Drum Cutter, and it can be seen in many engineering projects, such as open-pit coal mining, tunnel excavation, trench excavation, cement pavement demolition and so on. It has a very wide range of application scenarios and is an ideal equipment for modern precision construction.
The powerful milling ability of the Drum Cutter comes from the sharp teeth and powerful motor.
There are 40-90 cutter teeth welded on the milling disc. These cutter teeth are like sharp claws, cutting inert materials such as rock and cement. The cutter teeth are made of alloy material, which has high hardness and is not easy to be damaged. It can be used for milling mudstone, sandstone, weathered rock, concrete, etc.
YICHEN Vertical Drum Cutter
At the same time, the Drum Cutter adopts imported motor, which has stronger driving ability and longer service life. The transverse drum cutter is a direct output structure, and the motor is installed in the rotating part; the axial drum cutter is a gear output, and the motor is installed at the rear and driven by gears. These two types of Drum Cutters have their own advantages and should be selected according to specific working conditions.
Transverse drum cutter
Hetang Town, Ningde, Fujian Province, working condition: The upper epidermis of the marble mine is a sandstone mountain. The sandstone is scaly, the excavation effect of the breaker is very low, and the bucket cannot dig. The sandstone is scaly, the breaking hammer excavation effect is very low, and the bucket cannot dig. The construction party installed a YF-20RW Drum Cutter on a Sumitomo SUMITMO 200 excavator for milling sandstone. The effect is about 30-40 cubic meters per hour, and the loss of milling teeth is about 3-5 per day. In the case of no explosives operation, the construction party is still very satisfied with the performance of the Drum Cutter.
Axial drum cutter
Zhanjiang section of Shenhai Expressway, expressway reconstruction and expansion site, working conditions: The expressway has 4 lanes in both directions. According to the plan, it needs to be expanded to 8 lanes in both directions. Two YD-20RW axial drum cutters are installed on the Carter 320 type excavator to perform edge milling of the original subgrade stabilization layer. It extends to a depth of 20-30 cm and a height of 40-50 cm, which solves the problem that conventional equipment cannot excavate.
