### How a Grate Discharge Ball Mill Works

2015-8-13 Discharge Grates. The natural flexibility of rubber has allowed rubber manufacturers to produce grates that are less prone to plugging than the traditional metal grate. The main reason for this is the flexing or diaphragming action that a rubber grate is subjected to as it goes through its rotational cycle of a rotating mill.
