Brick production method using two types of clay, involves varying respective clay supply times to make different colour bricks from single production batch

摘要

The supply time for the two types of clay (3, 4) to the process cycle (28) is varied in order to create a succession of zones (30-30d) each containing a different amount of the first and/or second type of clay. The two types of clay produce different colour bricks. An independent claim is also included for the process apparatus, comprising two feed devices (1, 27) for delivering the two types of clay to a common supply point (26) on a clay transport device.
