Abstract

1482370 Mixing apparatus DEMITAS AS 21 Feb 1975 [21 Feb 1974] 7336/75 Heading B1C Concrete mixing plant comprises a premixer 3 for cement and water having a vertical agitating and circulating screw 10 and discharging through a valve 15 into a mixer 1 containing the aggravate. The constituents may be proportioned by weight or volume. The screw 10 rotates in a tube 9 the lower part of which has a replaceable lining 11 (e.g. of rubber or plastics) in which the screw is journalled, obviating the need for a bearing. [GB1482370A]
