The solution of the failure of the double roller granulator in operation

2021/04/14
During the operation of the double roller granulator, if the load current of the main point of the granulator fluctuates too much and exceeds the rated current value, the reasons are as follows:
① The crude fiber content of raw material is too high. The water content is too low or uneven, the extrusion pressure is too high, and the temperature is too high
② Too much impurities in the round material block the die hole, causing too much pressure in the granulation area
③ The solution is to adjust the water content or formula of the raw material, screen the raw material, remove impurities, and then granulate, dismantle the abrasive tools to remove impurities.

2. If the load current of the main motor is too small and the running current is less than 60% during the operation of the counter roller granulator, the reasons are as follows:
① The moisture content of raw material is too high to form grains
② The content of urea nitrogen in raw material is too high to form granules
③ The speed is too low and the granulator does not reach the required pressure range
④ The solution is to adjust the moisture or formula of raw materials and the feed rate.
