IHC Dredging Cutter Teeth
Dredging cutter teeth are the primary wear components on cutter suction dredgers (CSDs), responsible for excavating and breaking up materials from soft silt to hard rock. Hisea Marine manufactures high-performance IHC-compatible dredging cutter teeth designed to maximize cutting efficiency and minimize downtime. Engineered for complex abrasive underwater conditions, our teeth combine high tensile strength, hardness, and toughness to match specific soil mechanics.Different soil types demand different forms of penetration. Specific teeth are available for each soil type and all of the following fit the same adaptor:
• flared chisels are used for peat, sand and soft clay
• narrow chisels are applied in packed sand and firm clay
• teeth with pick points are used for rock.
Overview
Dredge cutter teeth are mainly used on dredgers for dredging construction in rivers, rivers, ports, etc., and are mainly responsible for the excavation of silt and gravel. it is also fitted on dragheads and dredging wheels. Under the conditions of complex abrasive wear conditions, the annual consumption of wear parts is quite amazing. Because the reamer teeth work underwater, the working conditions are quite complex, which requires that the reamer teeth must have high tensile strength and service strength, high hardness and sufficient toughness. Different soil types demand different forms of penetration. Specific teeth are available for each soil type and all of the following fit the same adaptor:
Soil Type / Condition | Recommended Tooth Profile | Key Performance Feature |
Peat, Sand, Soft Clay | Flared Chisel Teeth | Wide cutting face for high production rates in non-abrasive materials. |
Packed Sand, Firm Clay | Narrow Chisel Teeth | Increased penetration force to break through compacted layers. |
Rock, Hard Pan, Coral | Pick Point Teeth | Concentrated point load for fracturing hard materials; often reinforced with composite inserts. |
1. The unique male teeth design and easy locking system.
2. The unique alloy, in which a composite insert is placed to reinforce the working tip of the tooth.
3. Self sharpening of the tooth, better ground penetration, increased production.
4. Increased lifetime, decreased frequency and duration of maintenance.
5. Advance investment casting technology for producing with low cost.
6. Our dedicated heat treatment process finally extracts the maximum mechanical performance out of the carefully casted and forged complex alloys.
7. Can be customized according to your requirements or can provide OEM service.
