Claims
- 1. A method for mixing solids in a V-blender, said V-blender having a shell with an axis of rotation, comprising controlled axial flow perturbation of the solids being mixed, wherein the controlled axial flow perturbation is introduced by combined time-dependent rotation speed of the shell with a rocking motion, the rocking motion is defined by a speed of rotation of the shell of about 0 to about 50 rpm, a rocking angle of about 0.degree. to about +10 degrees or -10 degrees, and a rock to roll frequency of about 0 to about 31.4, and the time-dependent rotation speed of the shell is defined by a frequency of rotation speed changes per revolution of about 0 to about 1.
- 2. A method for mixing solids in a V-blender, said V-blender having a shell with an axis of rotation, comprising controlled axial flow perturbation of the solids being mixed, wherein the controlled axial flow perturbation is introduced by combined time-dependent, reversible rotation direction of the shell with a rocking motion, the rocking motion is defined by a rocking angle of about 0.degree. to about +10 degrees or -10 degrees, and a rock to roll frequency of about 0 to about 31.4, and the time-dependent, reversible rotation direction of the shell is defined by a speed of rotation of the shell of about 0 to about 50 rpm, and a frequency of rotation direction changes per revolution of about 0 to about 1.
- 3. A method for mixing solids in a V-blender, said V-blender having a shell with an axis of rotation, said shell having an intensifier bar which is rotatably mounted along the axis of rotation and a ribbon fixed to the intensifier bar, comprising controlled axial flow perturbation of the solids being mixed, wherein the controlled axial flow perturbation is introduced by combined rotation of the shell with rotation of the ribbon-bearing intensifier bar, the rotation of the shell is defined by a speed of rotation of the shell of about 0 to about 50 rpm and the ribbon-bearing intensifier bar rotation is defined by a ribbon speed of about 0 to about 3600 rpm.
- 4. A method for mixing solids in a V-blender, said V-blender having a shell with an axis of rotation, said shell having an intensifier bar which is rotatably mounted along the axis of rotation and a ribbon fixed to the intensifier bar, comprising controlled axial flow perturbation of the solids being mixed, wherein the controlled axial flow perturbation is introduced by combined rotation of the shell with time-dependent direction of rotation of the ribbon-bearing intensifier bar, the speed of rotation of the shell is about 0 to about 50 rpm, and the time-dependent direction of rotation of the ribbon-bearing intensifier bar is defined by a rotation speed of the ribbon-bearing intensifier bar of about 0 to about 3600 rpm and a frequency of rotation direction changes of the ribbon-bearing intensifier bar per shell revolution of about 0 to about 1.
