In order to make quality biochar fertilizer, it is advisable to crush your charcoal blocks/chips and compost caking into finer powder. This is beneficial for both powdery and granular charcoal fertilizer production. For the former, the finer the biochar fertilizer powder, the easier the fertilizer nutrient absorption. For the latter, the finer the material, the better the organic fertilizer pellets manufacturing. Here, for biochar chips and compost, a vertical fertilizer crusher is enough.

Then, for ensuring the nutrient balance of final biochar fertilizer you prepare, a fertilizer mixer is needed. It can blend compost with biochar powder evenly. According to your different requirements of capacity and efficiency, we design various mixers for biochar fertilizer making. Including large scale horizontal mixer, fast double shaft horizontal blender, low cost disc mixing machine, etc.

If you want to further improve the quality of your charcoal based fertilizer, you can choose to granulate biochar and compost mixture. Them you can make biochar fertilizer with features of easier transport, longer storage time and slower fertilizer effect release. For this, we can offer you pan pelletizer for small scale biochar fertilizer granulation, drum granulator for large scale carbon-based fertilizer granule production and double roller granulation machine for making organic fertilizer with biochar at a low cost.

With our fertilizer pellet screen machine, you can sieve out finished biochar fertilizer with size you need. In this way, you can produce biochar organic fertilizer granule with uniform size. How to dispose of left particles? Returning them to crush again and granulate into required carbon fertilizer pellets.

Provided you buy a disc or drum granulator for you biochar fertilizer making system, drying and cooling steps are necessary. Because, they make use of wet granulation method, which use water or liquid cohesive agent to speed up the process of biochar and compost to fertilizer granules. After the granulation, the moisture content of granular carbon fertilizer is 20%-30%. However, for more convenience for transportation and storage, it is advisable to reduce it to lower than 10%. To fast biochar fertilizer drying and packaging, rotary dryer and cooler are best choices.

Finally, for commercial biochar fertilizer production, packaging machine is key to shorten the time of biochar fertilizer making. It can finish the bagging of your finished charcoal fertilizer within 20 seconds. In addition, you can choose to pack your fertilizer into 10kg/bag, 20kg/bag, 50 kg/bag freely. The quantitative precision is lower than 2‰.
