How To Solve The Problem That The Extruder Does Not Discharge Material?

Common faults include: blockage and no discharging. There are many factors causing this fault, such as the raw material particle size is too large relative to the die hole size; too much material is fed in a short time and the speed is too fast; foreign matter blocks the discharge port; the pressure ring ratio The diameter is too small, the water supply and steam pressure are too small, and the temperature adjustment is not enough; of course the solution is also very simple. For materials with too large particle sizes, they need to be crushed to the appropriate particle size; adjust the feeding speed and feeding amount, and stop the machine for inspection Clean foreign objects; replace the pressure ring and readjust the water flow to ensure sufficient water pressure and steam pressure.

If the extruder discharge molding is poor and the particle diameter and shape are different, it may be due to uneven die hole size; blade wear, cutting speed is too fast or too slow; the temperature during processing is too high or too low; the raw material formula is inappropriate, the material Moisture content is too high or too low. Solution: configure the appropriate die hole, check the blade wear and replace it in time, adjust the cutting speed, modulator temperature and steam entry amount. If the puffed material powder is sprayed back, it may be because the feed is too fast or too much, or the discharge is not smooth or blocked. Solution: Control the feeding speed, investigate the reasons for failure to discharge materials one by one, and solve them according to the above methods.
