Charcoal changes from raw materials to charcoal through four processes: pulverization, drying, rod making, and carbonization. The quality of charcoal is focused on the process of carbonization. In this process, the problem is often encountered: Charcoal does not shrink it is good. So what is the reason for this problem? Gongyi Xiaoyi Mingyang Machinery Factory will analyze and answer the reasons for the bad shrinkage of charcoal during the carbonization process and the solutions:

Causes of poor charcoal shrinkage during carbonization

First: the carbonization process is too fast;

Second: The temperature rise is not enough.

The solution to the bad shrinkage of charcoal during the carbonization process

1. The carbonization process speed is too fast: too fast carbonization speed will inevitably lead to charcoal cracking. Once the charcoal cracks too much, it is difficult to shrink. Therefore, to solve this problem is to control the carbonization speed, and to control the carbonization speed is to control the carbonization temperature. It cannot be too high. Generally do not exceed 300 degrees;

2. Insufficient heating temperature: The temperature did not reach the required temperature when the carbon was refined. Generally, charcoal can shrink well only when the carbon refining temperature reaches above 800 degrees. The higher the carbon refining temperature, the better the shrinkage, but the higher the temperature, the lower the charcoal yield and the higher the cost. It is generally recommended to raise the temperature to 800 degrees.
