Special fine crusher hammer
The core advantages of the tertiary crusher hammer for power plants and coking plants are the wear resistance and impact resistance of the material, strong shape adaptability, and functional fit to the working conditions. The factory relies on its technology and production capacity advantages to achieve customization to reduce costs and increase efficiency.
1. Customized materials: balance hardness and toughness, adapt to harsh working conditions
The mainstream material is a bimetal composite structure: the working end of the hammer head is made of high chromium alloy (Cr content 26%-35%), with a hardness of HRC62-65, and the wear resistance is 3 times higher than that of ordinary steel hammer heads; the hammer handle is made of low alloy steel or high manganese steel, which has excellent toughness and is not easy to break.
Customized materials for special working conditions: Ceramic composite materials (reinforced by inorganic binder ceramic particles) are suitable for highly abrasive materials, and high-chromium and high-vanadium alloy materials are suitable for complex working conditions containing iron blocks.
The composition ratio can be adjusted according to the hardness and temperature of the coal material (-20°C to 120°C).
Production process: using lost foam vacuum casting and double-liquid composite casting process, one-time molding without falling off, combined with 1100℃ water toughening treatment + 600℃ low temperature tempering to eliminate casting defects.
2. Customized shape: fit the equipment and production capacity to reduce losses
Basic shape: square, rectangular, fan-shaped cross-section, etc. The weight range of 9.5kg-14kg can optimize the distribution of the center of gravity, and adopt symmetrical structure design to reduce single point wear.
Structural optimization: Adding reinforcing ribs to reduce stress concentration, stepped design to improve material crushing ratio, adaptable to mainstream fine crushers such as 1212/16-30 type, and installation dimensions can be customized according to equipment model mapping.
Customized details: The adjustable connection structure adapts to different fastening methods, and the guide rod design ensures operational stability and reduces vibration and wear of the hammer rod.
As a source manufacturer, the factory provides direct supply with no intermediate links, and the cost is transparent and controllable. Relying on the patented casting process and automated production lines, it independently develops customized materials such as bimetallic composites and high-chromium alloys. The hardness reaches HRC62-65, the wear-resistant life is 3-5 times longer than that of traditional hammers, and it is suitable for harsh working conditions of - 20°C to 120°C. Free surveying and working condition optimization services are provided, and the delivery cycle is shortened by 3-5 days.
