Twin-screw extrusion granulator is a new type of granulation technology different from traditional granulation. The double-screw extrusion granulator has reliable performance, high molding rate, wide adaptability to materials, low working temperature, and no damage to material components. , can be widely used in the granulation of products in feed, fertilizer and other industries.

 

Working principle

The special hydrodynamic conditions in the extrusion zone significantly strengthen the granulation function. Firstly, the high-speed, strong reciprocating soft and frequent shearing of the material in the reverse spiral motion in the extrusion zone increases the probability of the mutual combination of the material molecules. Secondly, due to the strong collision and friction movement of the material in the collision zone, the extrusion section The internal working pressure rises and maintains a high-pressure state stably, so that the temperature of the high-pressure section in the opposite extrusion zone rises rapidly to above 60°C, so that the material pressure and temperature fully meet the fluidization and granulation conditions, and the high-strength homogeneous effect changes the material The unique molecular structure can significantly strengthen the heat transfer, fluidization and extrusion process between materials, and greatly optimize the internal quality of granulated products, so as to obtain high-quality granulated products.
