Chemical Extruder Machine for Ceramic Catalyst

Screw extruder is suitable for material extruding in catalyst, chemical, pharmaceutical, active carbon and food industry.   
Features:
1.   Material auto pressing, avoiding manual operation
2.   Strong extruding force , extruded catalyst dia. can be 1mm or bigger
3.   Self-cleaning system, can handle sticky material
4.   water cooling for the extruder, reducing the possibility of extruding holes blocked due to material high temperature.
5.   Auto cut-off protection system which may caused by big screw torque, protecting the machine from being damaged by improper operation or
       impurities entering the feeding hopper.
6.   Frequency control
7.   Extruded catalyst cutting device, can cut the catalyst after extruding.
Working Principle:
Material is fed into the hopper, and then pressed onto the rotating screw by a couple of pressing devices in the pressing box (without manual punching). 
After fed to machine head by the screw, material is extruded through the template. 
The extruder screw thread is gradually reduced from the back to the front, so that the front end of template has the maximum extruding force, which can ensure the smooth extrusion of the material. 
The machine is equipped with material breaking screw to prevent material stick onto the screw. Aside from this, there is a groove at the contact part between extruding barrel inner layer and the material along the longitudinal direction of the extruding barrel, which can prevent the material from slipping.  
When the extruder is running, the extruding barrel will become hot due to the friction, the closer to the template, the hotter the barrel is, and can even carbonize the material, and result in overload of converter. To avoid the above phenomena, the extruding barrel is equipped with circulating water cooling system which has a good cooling efficiency.
Application: 
Catalyst, molecular sieve, activated carbon, rare earth, chemical, medicine, food etc extruding process.
