The shaping machine (secondary granulator) is a kind of secondary granulation equipment that rounds the raw material balls produced by the roller granulator and screens and removes burrs and scraps. It is mainly composed of a transmission device, a support device, and a roller. , Screen and other components, with stable operation, low noise, high efficiency, reliable performance, convenient maintenance, etc.
The raw material balls coming out of the roller granulation mechanism are sent to the feed inlet of the shaping machine by the slide pipe, and the material moves axially and radially along the cylinder wall in the roller of the shaping machine. The material is gradually rounded by the radial force of the roller in the cylinder, and the excess burrs are separated. When the material passes through the screen part, the rolled burr and dry material are agglomerated into a dense and hard mass (cake material) under pressure, which is called the extrusion process; the cake material is crushed and sieved to become granular material. Granulation process. The function of squeezing is to squeeze out the air between the particles, and to make the distance between the particles close enough to generate attractive forces such as van der Waals force, adsorption force, crystal bridges and embedded connections. The granules produced by extrusion granulation are mainly the strength of the granules formed by the force between molecules.
