Reasons and Solutions for Belt Slippage of Twin Screw Extruder

When the food extruder is used, there will be some problems. For example, the twin-screw extruder encounters the phenomenon of belt slippage in the process of making products. Is there any workaround in this case? Why does this phenomenon happen?

Because the wearing parts near the discharge port of the twin-screw extruder wear relatively quickly, and the wearing parts near the feeding port wear less, so when replacing the wearing parts, they should be replaced sequentially from the discharge end, not once Replace various parts. Secondly, the puffed raw materials should be cleaned to prevent foreign objects such as metals from entering the machine and damaging the parts. Check the quality of the equipment at any time, and pay attention to the replacement of wearing parts.


It belongs to a kind of equipment for processing puffed food, such as rice, corn, soybean, wheat, etc. in daily life. Its main working principle is to convert mechanical energy into heat energy, and use the heat generated when the machine rotates to knead and cook the food. The most obvious feature of the puffed food is that the volume becomes larger.


What are the reasons and solutions for the belt slippage of the twin-screw extruder? The belt slippage occurs during operation, which is actually a normal phenomenon.


1) The drive belt is too loose to cause slippage;


2) The load is too large (large amount of feed, small steam supply, poor discharge from the cone die, etc.).


Approach:


1) If the slippage is caused by the loose belt, the twin-screw extruder should be stopped, and the motor breakpoint should be determined to contact the machine to repair and tighten the belt.


2) If the belt slips due to excessive load, if the belt slips seriously, exit the cone die first, close the steam valve, reduce the feeding amount of the twin-screw extruder, and adjust the feeding when the current of the extruder is reduced to the normal current. The amount of material and steam is fed into the mold for production. When entering the mold, pay attention to the change of the motor current. After the mold is entered normally, slowly increase the amount of feed and steam until full-load production. If the belt slips slightly, adjust the amount of steam or feed appropriately. Generally adjust the amount of steam.
