Z Type Blade Sigma Mixer Manufacturer

       Z Type Blade Sigma Mixer

• Z Type Blade Sigma Mixer is modern heavy-duty mixer specially designed to produce uniform mixing and kneadingof highly viscous materials.this consists two shafts of 'Z' shapes blades moving in opposite direction at different speeds. Also available in stainless steel construction also and the system is also provided with jacket arrangement for handling heating or cooling application. The mixing action also involves combination of shearing, stretching, folding, dividing and recombining of material processed between sigma blades and container walls that ensure optimum results.
• Sigma Mixer is available in capabilities of 5, 10, 25,50, 100, 250, 350, 500 with power support of 1, 3, 5, 10, 15, 20,25, 30 HP. 

Specially designed for: The sigma mixer have application to produce highly viscous materials like different kinds of Chemical, Dyes & Pigments, Paint, Polymers Plastic, Putties, Plastic, Pharmaceuticals, Printing ink, stiff pastes, adhesives, polyester Compounds, flush colours, brake lining compounds, resign, soap, PVC coatings, Rubber compounds, Confectionery, Magnetic Tape Coatings, Ceramic, Carbon Black, doughs, Food Products, Fibre Glass, Grease, Lead Storage Battery, Soap & Detergent etc.

Operation of Sigma Blade Mixer

Material is loaded through the top of the container to typically 40 to 65 percent of the mixer's total volumetric capacity. The rotation of the blades is through heavy duty drive systems typically consisting of a motor, gearbox, couplings, and gears. The tip speed of the sigma mixer is generally limited to 60 metres per minute. Mixing may be carried out at ambient temperature or under controlled temperature conditions. The mixer troughs can be provided with jackets for circulation of hot or cold media to maintain the required temperature conditions within the mixer. The discharge of the material from the mixer container is either by tilting of the mixer container. bottom discharge valve, or through an extruder / screw located in the lower portion between the two trough compartments. The mixer may be equipped with any one of these discharge arrangements.

• The tilting discharge arrangement is most common. The tilting arrangement of the container may be designed for manual operation or may be mechanized using motorized or hydraulic arrangement.
  
• Tilting Discharge For materials of lower viscosity, the bottom discharge valve may be provided on the mixer trough. The design profile of the valve should be flush with the mixer trough to avoid any dead or unmixed pockets of material).
  
• Bottom Discharge The extruder/screw discharge has an advantage that materials can be directly discharged, extruded, in the required shape or size for further processing. In addition, the screw design eliminates operator exposure to hot materials if the mixing processes are carried out at high temperatures and/or with materials that are toxic in nature.
  

Salient Features
