Abstract. A systematic study on the comminution of a soft (coal) and a hard (iron ore) material is carried out to investigate the bulk comminution features of the hammer mill. The effect of the feed rate and the rotor speed on the mill efficiency in terms of reduction ratio, energy expenditure, fines produced and median size is investigated.

Hammer mill is easy to install, operate, dismantle and clean up. It occupies less space and can be easily placed in one corner of the manufacturing area. Various grades of material can be handled using screens of different sizes. It is versatile, and speed and screens can rapidly change based on milling requirements.
The hammer mill has 32 pieces of swing hammer of 6.4 × 50.8 × 120 mm on a 610-mm diameter rotor. The tip of the hammers reaches a linear speed of 115 m/s. The air flow rate of the blower is 63 m 3 /min. The total rated power of the hammer mill circuit was 42 kW (Table 1). Several different sized screens were used to investigate their effect ...
How Hammer Mills Work. A hammer mill uses forceful impact to pulverize material through a high speed rotating disc that has a fixed number of hammer bars, and the hammer bars are swung outward by centrifugal force. Raw material is fed into and then thrown out of the machine using centrifugal force, and it's crushed by being beaten …
