• More efficient crushed sand production

    The new RPMF machines produce even finer fractions as well as output material with a significantly higher proportion of fine sand (Fig. 2). As such, machines of this type are more efficient in producing crushed sand. The RPMF design is a variant of the rotor impact mills of type RPM, which are known in the industry as "sand makers."
