CONCRETE PUMP FOR THE WET SPRAYING PROCESS

摘要

The concrete pump is for the wet spray process. It has a control unit (20) in which the delivery volume of the pump (1) constitutes a reference value for the control of the compressed air flowing through the nozzle (3). The ratio of the values of the actual quantity of air per unit of time to the actual quantity of concrete corresponds to a desired value which gives the smallest fine dust outfall on applying the concrete.
