Hammer & Hammer Impact Mills
Hammer and hammer impact mills are suitable for crushing soft to medium hard materials (degrees of hardness according to F. Mohs 2 - 5).
For example: agglomerates, coal, limestone, gypsum and slag.
They are designed for large through-put volumes and trouble-free operation. Hammer impact mills are particularly suited for very coarse material whilst attaining a high degree of comminution with large through-puts. They are also used for comminuting clinker, rubble, quick lime, slag and ore.
Hammer mill HM 1 is provided for crushing smaller volumes in the laboratory and in sample preparation in sample processing plants.
In hammer mills the material is pulled into the crushing space by the hammers suspended from the rapid-running rotor. Comminution occurs mainly through impact in the area of the grid basket. The material being crushed remains in the crushing space until the degree of fineness required has been achieved, so that it can then pass through the discharge grid.
