Ribbon mixer, also called as ribbon blender, is one kind of slot type mixer for powder, granule and paste. According to different usage conditions, the ribbon blender can add functions such as spraying, heating, cooling and speed regulation. Double flight ribbon blenders provide a gentle, delicate mixing action. Ribbon blenders are manufactured with a central or total bomb-bay discharge, making them suitable for any type of plant layout. Thanks to the mixing action of the four flights that convey materials from the end plates to the center of the trough and vice versa, high quality blending is achieved, while guaranteeing the integrity of all ingredients, even the most fragile.
