Journal of Physics: Conference Series PAPER OPEN

1.0 INTRODUCTION Hammer mills, as the name implies, are mills for grinding grains into powder by impact [1]. The materials are poured into a loading hopper at top of the The range between 40 and 60 m/s is precisely of interest for operation of the special hammer mill, however. By means of tests, the factor may be determined to be: f = 0,4/vU1,5. A constant peripheral speed of 55 m/s for fine comminution and 40 m/s for coarse comminution applies, irrespective of equipment size, as a design criterion.Optimisation of design of the special hammer mill AT Minerals

The fabricated stone crusher was tested and the actual capacity was found to be 301 kg/h, through-put efficiency was found to be 75.4 %. The crushed products were well graded with 1.89 coefficientHammer mill Impact mills are similar in construction and principal to HSI and VSI crushers. Impact mills are used to pulverize feed material by impact against a surface or a bed of feed material. The feed material may be propelled by gravity or by a rotating impeller or rotor. The impellers or rotors can be vertically or horizontally orientated.How it Works: Crushers, Grinding Mills and Pulverizers
