Dispersion Kneader

Dispersion Kneader

Understanding the needs of the Plastics & Rubber processing industry and developing fully indigenous solutions to cater to these needs has always been the prime target of Zenith. When the need was felt for a mixer capable of hard mixing from process compounding view point, Zenith developed Dispersion Mixer. It can be employed in a wide range of material mixing, ranging from low viscosity adhesives to high viscosity rubber. “Zenith” Internal Mixing series is a highly developed range of Dispersion Kneaders for rubber and other polymers with high productivity and consistently good mixing with minimum electricity consumption.

Extruder Machine

Extruder Machine

“ZENITH” supplies two types of Extruder. Hot Feed & Cold Feed Extruder. Hot feed screw type extruders are heavy-duty machines built to suit individual needs. They are made in many different type and sizes to meet the production requirements for straining extruding, tubing, slab production or contoured shapes. The extruder’s size depends upon the hourly output required and method of feeding with a complete line of equipment is available to meet with all customers need.The Cold feed Extruders have been developed for processing cold rubber compound. Since these machines in addition to extruding profiles also plasticize rubber; they differ from hot feed extruders, they have longer screws; heavier gears boxes and higher drive power. According to present stage of development cold feed extruders can be used for extruding almost all rubber compounds, which are process able on hot feed extruders. Feeding is normally in the form of strips or pellets. Machines with longer screw diameters are often fed directly with wig-wag stored slabs.
