Many customers who make granules for the first time, When they receive sawdust pellet machine and ready to start production, there will always be similar problems, such as the sawdust pellet machine cannot press the particles! Let’s analyze the reason today
1. The water contained in raw materials is not suitable, and the water content is too high or too low so there is no way to form the particles, because our machine are made by physical suppression. There is no additional chemical component. The adhesive is combined by the proper water content and extrusion, so raw material moisture is one of the important factors.
It is generally recommended to control the moisture between 12-18%. Of course, the specific situation depends on the type of raw materials. If the humidity is too high, it is recommended to be equipped with the drying equipment.
2.The compression ratio of the mold is not correct.The compression ratio and moisture are both equally important factors, one is determined by the raw material, the other is determined by the grinding disc, and the two ratios are indispensable. This compression ratio must be communicated well with the manufacturer. Special attention is: for example, when pressing sawdust particles, it is suddenly found that the amount of sawdust is insufficient, and then artificially add other miscellaneous woods , this action will seriously affect the sawdust pellet machine! Because the compression ratio of different kinds of raw materials is different, if you have a variety of raw materials, you should communicate with the manufacturer to prepare a few more abrasives.
3. The gap between the ring die of the pressing roller is not adjusted properly. In the case of equipment testing, our company’s technicians will hand over to the customer for using and debugging, so as to avoid the situation that the particles do not come out of the machine.
