The production process of carbon briquettes is mainly divided into four steps. The first is to collect raw materials, which are mainly agricultural and forestry biomass waste, including rice husks, wood chips, straw, etc. The second step is the drying process, where the collected raw materials are dried to reduce their moisture content. The next step is crushing and screening, where large pieces of raw material are crushed mechanically and screened into sizes suitable for compression. The last step is compression molding, where the screened raw materials are put into a compression molding machine and compressed into blocks through high pressure.

With the development of the feed industry, people pay more and more attention to pellet feed. In Europe, except for layer feed, pellet feed is mostly used. The use of pellet feed has the following advantages.

Any equipment that operates with bad quality, improper installation, wrong operation, and poor maintenance may have much undesirable performance. So, what should we do if there is a bad phenomenon in the pellet machine? What are the corrective methods?

Grinding is an important process of pelleting. If the raw materials are grinded and then for pelleting, the adhesiveness of the materials will be increased, which will be good for pelletizing.
