Zhangjiagang Aiguo Biological Intelligent Drying Granulator, with its advantages of compact structure, easy operation, and low energy consumption, is widely used in industries such as pharmaceuticals, food, and chemicals. However, prolonged operation or improper handling can lead to equipment malfunctions, affecting production efficiency and product quality. Below are common problems and corresponding solutions to help you solve them in a timely manner and ensure the normal operation of the equipment.
The common problems and solutions of intelligent dry granulation machine are as follows:
1. Machine blockage issue
Reason: The gap between the mold rollers is too large or too small, the steam quality is poor (high moisture content or unstable pressure), and the tempering effect is poor, resulting in excessive moisture content in the material or insufficient starch gelatinization.
Solution:
Adjust the gap between the mold rollers to a "seemingly close but not close" state to ensure that the material is evenly compressed.
Use dry saturated steam (with stable pressure and low moisture content) and monitor the moisture content of the quenched and tempered material (it is advisable to hold it in a ball and release it when loose).
Optimize the tempering time and temperature to ensure sufficient gelatinization of starch.
2. The pressure roller is worn or damaged by high temperature
Reason: Improper clearance (too small, intense friction, too large, insufficient pressing force), insufficient lubrication, or transmission system failure (such as loose belt).
Solution:
Adjust the gap between the pressure roller and the ring mold according to the requirements of the model, and regularly check the lubrication system.
Use suitable high-temperature lubricating grease to avoid grease contamination or improper installation.
3. Low particle forming rate
Reason: The material viscosity is too high, the pressure of the pressure roller is insufficient, or the mold is worn.
Solution:
Pre treat materials (such as crushing, drying) to reduce viscosity.
Check the pressure of the pressure roller and the condition of the mold, and replace worn parts if necessary.
4. Abnormal equipment vibration
Reason: Unbalanced transmission shaft, worn bearings, or loose base.
Solution:
Correct the balance of the transmission shaft, tighten the base bolts, and replace worn bearings.
5. Cleaning and maintenance issues
Key steps:
Dismantle the storage bin, loosening hopper, and support net, and clean the remaining materials with a brush or damp cloth.
Regularly inspect the seals to prevent material leakage or contamination.
