Product Introduction
The material of the disc cutter ring is crucial for the disc cutter's ability to excavate hard rock.
Our company offers different types of cutter ring materials for different strata. Generally, there are four types of blade shapes for disc cutter rings:
standard cutter rings, wide - blade cutter rings, heavy - duty cutter rings, and cutter rings with alloy - inlaid teeth， to meet the requirements of different strata.
For specific information, please refer to the following picture.
| Cutter Ring Series | Size | HR | Design Features | Subject Range
|
| Standard Cutter Ring
| H=19.3 H=22
H=25
| HRC57-59
| The cutter ring has good toughness and wear resistance. The cutter ring is designed with a flat top and a slope surface, with a wide application range.
| Suitable for moderately and strongly weathered strata with a uniaxial compressive strength of rock less than 100MPa, such as conglomerate, marble, sandstone and limestone strata. |
| Wide - edge Cutter Ring
| H=28
H=30
H=32
| HRC57
-59
| The blade is designed with a wide edge, increasing the thickness of the cutter ring and improving the wear - resistant distance
| Suitable for strata with more pebbles, including strata with large - particle pebbles and boulders.
|
| Heavy - duty Arc - top Cutter Ring
| R=13
R=15
| HRC60
-62
| The blade is designed in an arc shape. The special material is combined with the targeted heat treatment process to ensure the toughness of the force ring and take into account its wear resistance.
| Suitable for weakly weathered and slightly weathered hard rock strata with a uniaxial compressive strength of rock more than 100MPa, such as granite, diorite, limestone, gneiss, basalt and other strata. |
| Wedge Tooth Alloy Cutter Ring
| Wedge - shaped | Alloy Block
HRA86
| The blade of the wedge tooth alloy cutter ring is conical, and the rock breaking mode of the cutter is more point contact, with great rock breaking strength.
| The maximum applicable formation of the wedge tooth cutter ring is about 80MPa, especially for the rock stratum of about 60MPa, such as sandstone and limestone, with fast excavation speed and long service life.
|
| Brazed Alloy Block Cutter Ring
| 25 | Alloy Block
HRA86
| The alloy of the alloy block cutter ring is wider than the cutter ring matrix, which can protect the matrix and avoid the situation that the alloy falls off due to the premature wear of the cutter body.
| Suitable for strata with strong abrasion below 30MPa and long excavation distance, such as sand layers.
