Abstract

The production of mouldings, for example concrete blocks, with uniform bulk density and accurate dimensions is achieved by measuring the block height and weight of the demoulded mouldings and by calculating the bulk density from these two values. If variations from the desired values occur, the filling level is immediately altered. Both measurements are carried out outside the vibration area so that precision measuring instruments can be used. To eliminate the influence of different board heights, the board upper side and the block surface is sensed and the difference determined. The procedure for determining block weight is such that the board with the blocks thereon is weighed and the known board weight is subtracted as the constant.
