Dry granulation steps and work principle

How to make fertilizer pellets with dry powder granulator? There are some details of operation process.

• Eerstens, put the material into horizontal feeder driven by the rotary screw. And the material is gradually degassed in the process of moving forward.
• Destyds, increasing the density by forcing material into the table press. The table press will transport the high density material of the horizontal feeder, through a pair of hydraulic cylinders(adjustable pressure) push the press roll. Then it makes the material roll into 2-4 mm thin film, and complete the degassing work.
• Derdens, rolled think slice through the cutter teeth of shear crusher, cut into pieces with optional shapes. And then fall into the whole grain machine.
• Fourthly,it make the fragments force out of the sieve plate under the squeezing of the whole grain knife.
• Uiteindelik, after we use it for screening the extruded particles, customers can obtain the desired size of the fertilizer pellets. So far, the whole process of granulating has been finished.
