The base structure (3) is made of concrete or the like and includes at least one trough or hopper bottomed tank (5) for the separated particales, wall structure (4) is made of steel and attached to the base structure (3) with a substantially rigid joint (5). The wall structure (4), except for the rigid joint (6), is provided to allow thermal expansion and contraction.
