Hammer material and model of crusher affect each other

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) February 17, 2012 -- Crusher hammer abrasion condition is affected by numerous factors, such as material prosperities (including feeding size, material type, hardness, moisture, temperature), hammer linear speed and the gap between grid plate. Therefore, it is very important to choose suitable material for crusher hammer. After long-term practice and experience, the experts of Henan Hongxing has got conclusions and given the following suggestions in the relationship between crusher hammer materials and crusher types.

For large scale crusher with a feeding size of over 400mm, it is should be installed big crusher hammer with a weight of 50~125kg. Owing to crusher hammer needs to bear huge impact force and high manganese steel has high toughness, Hongxing experts suggest that manufacturers had better choose super high manganese steel alloy or alloyed high manganese steel to process crusher hammer.

For small crusher with a feeding size of less than 50mm, it is should be installed complex hammer with a weight of 15kg. Owing to crusher hammer needs to bear smaller impact force, Hongxing experts suggest that manufacturer had better choose medium carbon alloy steel to process crusher hammer, whose head is made of high chromium iron and its handle is made of 35# steel or low alloy steel.

For small and medium size crusher with a feeding size of less than 200 mm, it is should be installed crusher hammer with a weight of less than 50kg. Owing to crusher hammer need to bear relative small impact force, Hongxing experts suggest that manufacturer had better choose high carbon alloy high manganese steel or medium and low carbon alloy steel to process hammer.

For fine hammer with a feeding size of less than 100mm, it is should be installed fine crusher hammer which is made of super high chromium iron. Owing to high chromium iron’s hardness HRC60and its impact toughness ak8J/cm², the service life of fine crusher hammer is improved by three to five times than that of high manganese steel hammer.
