Common Problems with Biology organic Fertilizer Dryers

 Biology organic fertilizer dryers frequently malfunction during daily production, directly impacting finished product quality and production capacity. Common problems mainly fall into the following categories:

First, uneven drying results in significant differences in the finished product's moisture content. One side is overly dry with excessive dust, while the other is damp and prone to clumping. This is primarily caused by uneven material distribution, wear and tear of the internal lifting plates, insufficient material agitation, and improper hot air temperature matching. Excessive initial temperature leads to an outside-dry, inside-wet mixture.

Second, material sticking to the drum and forming build-up on the inner wall is the most common problem. Excessive initial moisture content in the raw materials and strong organic matter viscosity, combined with a low initial drying temperature, cause the material to easily adhere to the drum wall after entering, accumulating over time and severely impacting drying efficiency.

Third, high finished product temperature and inability to cool down result in excessive discharge temperature, easily leading to secondary moisture absorption, mold growth, and microbial burn, damaging the activity of the microorganisms. This is often caused by insufficient drying airflow, weak exhaust fan at the tail end, and a too-short cooling section.
Fertilizer production machine often experiences problems such as material blockage, poor feeding, and clumping of material at the feed end, as well as a mismatch between feeding speed and drying rhythm. Other issues include excessive machine vibration, high bearing temperatures, and abnormal noise, mostly caused by loose anchor bolts, worn and misaligned rollers, and inadequate lubrication.

Furthermore, problems include excessive dust, strong odor in the exhaust gas, and clogged or aging dust removal devices. These issues not only pollute the environment and cause raw material loss but also easily lead to material accumulation in the induced draft fan and material sticking to the fan impeller, resulting in imbalance.
