Mechano-chemical (MC) synthesis of photocatalyst compound powders in ZnO-TiO2 system was carried out by a new high energy ball mill with functions of the powder layer formation onto inner wall of revolving vessel and the intensive impact of medium ball on the layer. Crystal grown of compound zinc titanate in MC treatment, shown in XRD patterns, was different with inner diameter of revolving vessel and inclined angle of "guide vane". Higher diffraction peaks and narrower half width of compound ZnTiO3 powders synthesized in MC treatment were obtained over 20 h of treatment time, compared to that by a planetary ball mill. Furthermore, the high intensive mill is capable to obtain higher yield of MC treated powders.
