ACTIVATOR Russian patent published in 2000 - IPC

FIELD: manufacture of building materials on base of inorganic binders. SUBSTANCE: activator has housing, turbine with shaft, disks with circular concentric projections; one disk is secured on housing and other disk is fitted on turbine shaft connected with drive. Circular projections of one disk are located between circular projection of other disk. Disks are provided with baffle plates made in form of cylinders of oval section; at one end, they are secured on circular projections of disk over diameter and at other end, they are interconnected by means of rings. Baffle plates are mounted on disk secured on housing and are oriented relative to radius at angle of 80 to 100 deg and those mounted on disk fitted on shaft are oriented relative to radius at angle of 30 to 60 deg. EFFECT: intensification of grinding; enhanced efficiency of activation of suspensions being prepared due to considerable increase of relative collision of particles. 2 dwg
