We know that from the material alone: high chromium cast iron has a high hardness coefficient, up to 65HRC, good wear resistance;  The hardness of high manganese steel is 58HRC and wear resistance is general.  Forging hammer hardness 50HRC;  The same hammer shape, high chromium alloy hammer is wear-resistant than other materials, but the specific wear-resistant amount, how long can be used, many factors affect.  For example, the hammer type, fan-shaped hammer end than the ordinary square hammer end of the working area, the thickness of the hammer end.  The same high chrome hammer, for example, some manufacturer carry a thin layer of chrome hammer, hammer some manufacturer the end is high chromium alloy, we know that high chrome composite hammer head by the hammer handle high quality cast steel and high chromium alloy hammer end two kinds of metal components, whether hammer hammer wear depend mainly on the high chromium alloy, high chromium alloy than the big, long service life, high chromium alloy proportion is small, Short service life.  Moreover, the high chromium alloy hammer on the market, some Cr24, some Cr26, some Cr28, Cr28 is certainly more wear-resistant than Cr24, and the chromium content affects the production cost of the hammer, the content of the qualified high chromium alloy hammer is required for the cost, the price will not be very low

Wear-resistant hammer installation crusher is located in the number of crushing process, a group of hammer, the speed of the rotor running line of the equipment, broken material, material is dry or wet, these will affect the service life of the crusher hammer. Hammer crusher is located in a broken process, certainly than in two broken, three broken life is short, wet material than dry material cost hammer, the same crusher cavity a rotor put 20 hammer is certainly lower than 40 hammer production, hammer wear is more serious. The greater the speed of hammer end running line, the higher the crushing efficiency. These factors will affect the service life of the wear-resisting hammer head, so don't say these preconditions on ask high chrome wear-resisting hammer head can use how long are all play rascal, ha ha, so, if you have this aspect of the problems and questions, contact me right now, mature casting technology and years of industry experience, help you to solve all kinds of crusher wear parts use small knowledge.
