Key Advantages in Practical Use
1. Long service life, reducing spare parts costs
The wear resistance of the high-chromium wear-resistant layer is 3–5 times that of ordinary carbon steel hammer heads and more than twice that of high-manganese steel hammer heads; this reduces replacement frequency in sand and gravel plants and cement works, saving on spare parts procurement costs.
The composite structure addresses the shortcomings of traditional single-material hammer heads: pure high-chromium hammer heads are brittle and prone to shank breakage; pure carbon steel hammer heads lack wear resistance and wear out within days.
2. Wide range of compatible operating conditions and high versatility
Suitable for use in heavy-duty hammer crushers, small hammer crushers, mobile sand-making machines, coal gangue crushers and construction waste crushers;
Suitable materials: limestone, granite, river pebbles, basalt, coal, steel slag, construction waste, brick rubble and other soft and hard materials.
3. Impact-resistant, fracture-resistant, safe and stable
The tough base material of the hammer shank cushions the instantaneous impact force from large rock fragments, whilst the high-chromium working surface is hard and wear-resistant, striking a balance between toughness and hardness; during continuous, high-intensity crushing operations, hammer head fractures and flying fragments are extremely rare, thereby preventing damage to the equipment chamber and safety incidents.
4. Reduced overall operational and maintenance costs
Extended replacement intervals minimise downtime for disassembly and reassembly, thereby enhancing the production line’s continuous output capacity;
Wear-resistant mounting holes prevent reaming, protecting pins and rotor discs whilst simultaneously reducing wear on rotor components;
Stable crushing efficiency: the wear-resistant layer wears evenly and does not dull rapidly, ensuring consistent output particle size over the long term and eliminating the need for frequent liner adjustments.
5. Convenient storage and transport
The castings are manufactured as a single, integral piece, offering high strength and resistance to impact damage; they can be stacked and secured with wire ties as shown in the illustration, minimising the risk of parts becoming loose; clearly marked specifications simplify warehouse management.
