Mixing (solid, liquid and paste)

Mixing (solid, liquia) Solid-Solid Mixing: Importance, fundamentals, batch homogeneity, types of solids-mixing machines: (mixing mechanisms and operations) double cone, twin shell, horizontal drum, double-cone revolving around long axis, ribbon, vertical screw, batch muller, continuous muller, twin rotor. Performance, characteristics, selection of machines. b) Paste Mixing: Definition, importance, simple blending, dispersion operations and general equipment design. Standard types of equipment and operations, change-can mixer, change-can mixer with planetary motion, change-can mixer with rotating turntable, troy angular mixer, duplex mixer, stationary-tank mixer, kneader, mullers, three-roll mill, selection of process and mixer. c) Liquid Mixing: Definition, importance, mixing equipment, axial and radial flow impellers, mechanisms, flow patterns, impellers, flat-blade and curved blade turbines, spiral turbines, paddles, gate impellers, anchor impellers, different fixed-mounted and portable positions, shaft lengths, baffled and unbaffled tanks, vortex formation and its control, selection of impeller. d & paste)
