Design of hammer mills for optimum performance CORE

Abstract. Hammer mill manufacturers are under increasing pressure to deliver mills of high productivity with a reduced level of vibrations. However, in practice, excessive wear of the rods carrying the hammers takes place, and cracks develop in the vicinity of the holes holding the rods with the hammers, with the possibility of breakaway fracture and disastrous consequences.For high production of crushed coal it is better to use the hammer mills having higher contact surface of hammer. Hence, it is easy to produce the high rate of crushing coal with in less time.The purpose of the crushing is to produce the coal having size of less than 3mm (More than 3mm) and the moisture content is 10-12 percent .The type of hammer mill used is a Reversible swing hammerDesign and Fabrication Of Hammer Mill Mechanical Project2021-4-24 · Small grain hammermills can be operated on household current.
