Straw briquetting machine is a mechanical equipment that processes and presses corn stalks, rice stalks, sorghum stalks and other crop straws into briquetted fuel or feed. In the process of straw briquette production, sometimes there are all kinds of abnormal appearance of finished products.

There are many reasons and solutions for these abnormal appearance of straw briquette.

1. The surface of straw briquette shows the trend of “falling apart”.

One of the reasons for this phenomenon is that the water content of processed raw materials is low, and the solution is to control the water content of processed raw materials well. The second reason is that when the finished product is placed, water enters, and the solution is to ensure that the finished product is dry and free of water.

2. The surface of straw briquette is not smooth and uneven.

The more direct reason for this phenomenon is the problem of processing raw materials, which contain large-diameter and hard raw materials, and the high moisture content of the raw materials will lead to the uneven surface of the processed finished products. The solution is to crush the raw materials before briquetting, and ensure that the moisture content of the raw materials is moderate.

3. The briquette is bent and cracked.

This phenomenon is mainly caused by insufficient cutter position and pressure and large processing raw materials. The solution is to increase the pressure of straw briquetting machine to press the finished product, improve the position sharpness of the cutter, and crush the raw materials to a proper fineness.

4. Vertical cracks appear on the surface of the briquette.

The main reason is that the raw material moisture is too large. When the die is extruded, this phenomenon will occur under the action of the reaction force of water and the principle itself. The solution is to control the moisture content of processed raw materials and avoid excessive moisture.

5. There are cracks in the cross section of the straw briquette, but it is not completely broken.

The main reason for this phenomenon is that the raw materials contain relatively long straw, and the solution is still to crush the straw.

Through the analysis of the abnormal appearance of straw briquetting and its causes, we found that the fineness and moisture content of raw materials are the key factors that affect the quality of finished products pressed by straw briquette machine. Therefore, when making straw briquette, we must strictly control the quality of raw materials to ensure the production of qualified straw briquette products.
