Sand Mullers- from MIFCO
WEBSWIF-MUL is Designed for More Efficient Mulling Action. Casting defects are generally caused by poor sand properties. These defects are greatly reduced when molding sands are mulled correctly. A true mulling action requires each grain of sand to be evenly coated with clay and binders.
Sand Compactability and the Factors That Affect It
WEBAs sand and clay is mulled thoroughly, most of the clay platelets have absorbed water and very little further absorption can take place making compactability more stable after discharge from muller. Average mulled time for the sand mix depends on mulling time for each cycle, system replacement time, sand loss, and new material input.
