锤式破碎机和反击式破碎机是一种广泛应用的破碎机械,锤头和板锤是破碎机的主要易损件。以前它们多采用传统的高锰钢进行制造,经多年的使用、观察发现高锰钢锤头和板锤不耐磨,使用寿命短。破碎石灰石时,锤头的寿命为2～3个月,板锤寿命大约1个月,磨损严重的板锤(破碎锻烧后的高岭石)使用3天就须更换。由此造成人力、物力的极大浪 Hammer crusher and impact crusher is a widely used crushing machinery, hammer and hammer is the main crusher fragile parts. They used to use more traditional high manganese steel manufacturing, after many years of use, observed that high manganese steel hammer and hammer not wear, short life. Broken limestone, hammer life of 2 to 3 months, hammer life of about 1 month, severely worn plate hammer (broken calcined kaolinite) to use 3 days to be replaced. The resulting human, material and great waves
