How to Improve the Hardness of Pelletize Produced by Organic Fertilizer Ball Shaping Machines?
Improving the hardness of pelletize produced by organic fertilizer ball shaping machine requires systematic optimization of three aspects: material ratio, forming process, and post-processing. Hardness essentially depends on the density and bonding strength of the internal structure of the pellets, which primarily depends on the formula. Simultaneously, ensuring sufficient fermentation and high decomposition of the raw materials allows the fibers to better intertwine during rolling. The fineness of the raw material grinding also needs to be balanced; excessively fine raw materials, while easy to form, may result in brittle pellets. Retaining a moderate amount of coarse material helps enhance toughness. Adjusting process parameters during the forming process directly affects the initial density. The core is precisely controlling the material moisture content, typically maintaining it within the optimal plastic range of 25% to 35%. Too low a moisture content prevents bondin...
