The twin-shaft batch mixer of type OX has been developed especially for this purpose as a standardized series machine to produce ready-mixed concrete in a cost-effective manner. Over 130 years of experience from BHS in mixing concrete is underlined in the technical details, which make quite a difference in practice – in the quality of the mixing result, in the high operating speed, and predominantly in the ability to reliably withstand the demands of the production of ready-mixed concrete in 24 /7 operation.
