Twin Sigma Mixer UTSM-1500

  • UTSM-1500 is a batch type sigma mixer designed for uniform mixing and kneading of powder and liquid.
  • It consists of mainly
    1. Strong base frame.
    2. U shaped mixing chamber.
    3. Z shaped twin blades assembled on rotating shafts.
    4. Different sized nozzles for solid charging, liquid charging, discharging etc.
    5. Drive arrangements.
  • The pre-determined mass of dry powder is being charged through it' s port. Then pre-determined mass of liquid is being sprayed in to the powder with in pre-determined time. Continue the mixing for pre-determined time. When mixing is over, open the discharge valve,reverse the direction of rotation of screw at pre-determined rpm (as per required flow rate).While discharge, continue the blade rotation till all the materials are discharged. Continue all the above process for next batch.
  • The rotary motion of the Z shaped sigma blades create axial, radial and mixed action on the mass which in turn throw the mass in to vessel walls and each other. At the same time the discharge screw rotates in the reverse direction. Reverse action of the screw and the geometry of blades bring back the mass for intensive mixing. The action of the blade and screw causes repetitive stretching, folding, kneading of the viscous material, and thus resulting in homogenous mixing.
  • Production capacity of these pieces of equipment is 400 to 500 kg / batch.





  • Chemical
  • Food
  • Pharmaceutical

  • Dust-free closed system
  • Thorough mixing.
  • Handle products with a wide range of particle size and shape.
  • Increased efficiency of liquid to solid contact by spraying.
  • Z shaped blade provide a proper mixing
  • Control the residence time by determining process time and RPM.

Successfully scaling up to full production means replicating your pilot results. How do you do this? The key is to use lab milling equipment that exactly

Particle size is a critical parameter in material properties. Monitoring and measurement of grain size distribution during processing is critical to successful product.



High shear granulator is the new mixer range that builds on the proven Umang technology and its benefits. Similar design of process bowl, mixer and chopper ensures that process

Twin Screw extruder is widely used for making pellets of different sizes starting from minimum 400 microns to maximum 2000 microns.

Integrated Mixer & Extruder is a compact design equipment with production capacity of 150 kgs of pellets per hour on continuous basis.

Die Roller Extruder as two rollers one is perforated and the second is knurling roller both are horizontally placed with minimum gap of 0.3mm.

The process involves the deposition of successive layers of an active compound onto nonpareil seeds resulting in the formation of uniform size pellets.
