The core requirement of a bio-organic fertilizer production line is preserving the activity of beneficial microorganisms in the raw materials. These materials are often half-wet after fermentation or dried auxiliary materials. Therefore, the selection of a crusher must balance particle size uniformity and the protection of microbial activity; this is crucial for ensuring the quality of the finished product.
The half-wet material crusher is the core suitable model, primarily designed for processing fermented raw materials with a moisture content of 20%-30%. It employs a low-speed, gentle crushing mode, preventing damage to microbial activity from high temperatures and violent impacts. It also avoids material sticking and clogging, producing uniform particles suitable for subsequent granulation.
The cage fertilizer crusher can be used as an auxiliary to process dried auxiliary materials (such as dry straw and wood ash). Its moderate crushing force effectively breaks up lumps, and the dried materials, after crushing, retain no excess moisture, preserving the living environment of the beneficial microorganisms. It can be used in conjunction with the semi-wet material crusher.
In summary, a semi-wet material crusher should be prioritized for the bio-organic fertilizer production line, supplemented by a cage crusher, to balance the activity of the microorganisms and the compatibility of the raw materials, ensuring smooth production and that the finished product meets the standards.
