Cone Screw Mixer

CONE-SCREW MIXER is highly efficient homogenizer and used especially for gentle mixing of powders, granules, slurries or pastes when they are brittle and/or heat sensitive. This mixer consists of a conical vertical vessel with a screw parallel to the side of the cone. Material is fed from the top of the cone. The screw rotates around its own axis and the axis of the screw rotates around the periphery of the cone by means of specially designed gearbox and arm assembly. Both drive for screw and arm are at top. Gearbox has two input shaft and two concentric output shafts.

One shaft rotates arm while other shaft rotates screw by coupling. The material being mixed is lifted up from the apex of the cone by screw and the center of the mass collapses down. The orbiting screws continuously stirrs the mass, results into a unique three dimensional mixing system. The design and orbiting motion of screw is such that perfect distribution of even small quantities of highly different characteristics of material added is effected and the homogeneity of the final product is assured.

· Lifting by the screw
· Collapsing down the center of the mass in the cone
· Stirring by arm

The design and orbiting motion of screw is such that perfect distribution of even small quantities of highly different characteristics added is affected and the homogeneity of the final product is assured.

Bottom support of the screw is given by any of following types
[a] Free hanging
[b] Lower pintle support
After mixing, material is taken out from bottom by means of various type of discharge spout given at the bottom.

Advantages
  • Orbiting Screw offers a unique three dimensional high quality mixing.
  • Equilibrium mixture is very close to the optimum.
  • Because there is no free fall under gravity, there is no innate tendency for  segregation.
  • Specially designed gearbox mounted at top and lower pintle support eliminates bearings at bottom help to avoid jamming of screw, reduce maintenance, and ease of cleaning and less on contamination.
  • Fast yet gentle mixing with minimum heat generation and lower power consumption.
Model varient
  • Working Volume – from 500 liters to 15,000 liters.
  • Type of Screw – General, Tapered, Ribbon, Satellite
  • Bottom Support – Cantilever, Pintle
  • Operation – General, Heating, Vacuum
Applications
Agrochemicals, Dyes, Cosmetics, Chemicals, Minerals, Agricultural etc.
