Abstract
The present invention relates to a hammer for use in a hammer mill and particularly provides an improved hammer of separate type in which a hammer head is detachably coupled with a hammer body. A material of the highest level in abrasion resistance such as high chromium cast iron is employed to form the hammer head. In spite of brittleness of the material, there is no such problem as breakdown due to impulse forces applied and transferred immediately because there is no looseness at all in the engagement of the coupled hammer body and hammer head. Energy applied is sufficiently utilized thereby improving energy efficiency.
