When discussing the importance of ore in industrial processing, we often overlook a key factor: moisture. Wet ore, which contains high‑level moisture, is an inevitable by‑product of ore mining and washing operations. However, before further industrial processing, wet ore needs to undergo drying treatment to cut down its moisture content. Why is that? This is because excessive moisture will negatively impact ore crushing, screening, smelting and subsequent processing performance, resulting in low production efficiency, higher energy consumption and increased processing costs. Therefore, the emergence of ore dryer machines is crucial. These ore dryers effectively reduce the moisture content of wet ore, thereby improving processing efficiency and the comprehensive utilization value of raw ore.
Traditional dryers have not been improved to cater to the characteristics of coal. Therefore, using traditional dryers for coal drying is difficult, with the process being hard to control. The resulting product from traditional drying machines often has uneven moisture content, with the exterior being dry while the interior remains wet. Moreover, traditional rotary dryers are costly and unsuitable for coal drying. With the advancement of technology, new types of coal rotary dryers have emerged. AGICO has developed coal dryers specifically designed for coal drying, taking into account the unique drying characteristics of different types of coal. These coal dryer machines offer advantages such as high processing capacity, low drying costs, minimal wear and tear, and stable operation, making them bestsellers in the market for many years.
Coal Dryer Machine Process
The coal rotary dryer adopts a low-temperature four-stage drying process to ensure the quality of dried coal remains unchanged, reducing the moisture content of coal to below 13%.
※ In the first drying zone, most of the moisture is removed at 400°C under high humidity conditions, ensuring that the chemical composition of coal remains unchanged and is less prone to combustion.
※ The second drying zone operates at room temperature of 300°C, using medium-temperature strong airflow to efficiently remove moisture, preventing the coal from coking.
※ The third drying zone maintains an indoor temperature ranging from 120°C to 210°C. Utilizing crushing devices inside the drum, the material is repeatedly impacted and dispersed, undergoing concurrent drying.
※ The fourth drying zone, designated as the high-exhaust zone, operates at a temperature of 60°C to 80°C. Utilizing a negative pressure airflow system efficiently removes moisture.
