Beater Mixer

• Consist of rotating blade which has planetary motion so as to reach all parts of the vessel

Disperser

• Heavier in construction and draws more power than a kneader.
• Mixes additives and coloring agents in stiff materials.

• Internal Mixer
• Heavy Duty two Arm Mixer
• 30-40 rpm arm speed
• Compound rubber and plastic solids

• Smearing or rubbing action
• Consist of a pan with central vertical shaft
• wide heavy wheels attached to the shaft, which drive the wheels in circular path
• plows guide the solid under the wheels
• especially effective in uniform coating of particles with a small amount of liquid

• Large amounts of mechanical energy are needed to mix heavy plastic masses.
• Only part of energy supplied is directly useful for mixing.
• Mixers that work on small quantities of material, dividing it into very small elements, make more effective use of energy than those that work slowly on large quantities.
• The shorter the mixing time required to bring the material to the desired degree of uniformity, the larger the useful fraction of energy supplied will be.
• The energy supplied appears as heat, which must be removed to avoid damaging the machine or the material.
