Then arrive the charging aperture of extruder, so can ensure that the granule entering preheating chamber fully enters extruder after preheating completes
Charging aperture, it is ensured that efficiency, save the energy.
In sum, when the feed hopper endoparticle size being sent to extruder is uneven, bulky grain and little granule enter sieve
Separating device, the screening plant of vibration screens out bulky grain and little granule, and then bulky grain enters bulky grain preheating chamber, and little granule enters
Entering little granule preheating chamber, the two preheating chamber is designed with heater, can carry out bulky grain therein and little granule respectively
Heating, temperature-adjusting device can make the temperature in bulky grain preheating chamber higher than in little granule preheating chamber, and the least granule is not
With through high temperature or long-time heating, and bulky grain can be the biggest on demand through higher temperature or the heating of long period
Particle surface can form molten state, through such in various degree heating after, send into extruder charging aperture granular size just than
More uniform；Preheating chamber the most sheathed outer heat-insulation layer can heating devices heat to a certain extent after, heater cuts out, and utilizes
The heat-insulating property that heat-insulation layer is good carries out constant temperature insulation, is so greatly saved the energy, consistent with energy-conserving and environment-protective theory.
