# Dynamic analysis of hammer mill document

The Hammer Mill Hammer is used to crush coal of 200 mm size to a crush size of 30 mm. Hammer is modeled in CATIA Software and is analyzed by ANSYS software. Material used for Hammer is SA-105 Carbon Steel, which has an allowable stress of 96.5 N/mm2. Modal Analysis: This is

• Investigation on the Motion States of the Hammers while

Actual motion states of the hammers while hammer mill steady running is an important analysis basis for the dynamic characteristics of the hammer mill rotor and the wear mechanism between hammers and hammer pivots. To investigation the actual motion states of hammers, a high-speed photography was used in this paper to record the instantaneous states of the hammers
