The production process begins with a multi-hopper batching system that allows for simultaneous handling of 2-6 types of raw materials. This section is usually positioned at the head of the line to facilitate granule material input strictly with required proportions. Usually, this occupies a significant footprint. Every hopper can be 1.8*2.5 m.

As the heart of the BB fertilizer making process, granules mixer ensures a uniform blend of all materials. For a 20 t/h output, the 1.7*8m rotary drum blender is the best choice for you. With drum shape design, it can mixing 20 tons of N,P, K fertilizer granules evenly quickly by rotation.

The cache bin provides a buffer zone between fertilizer granules mixing and blended NPK fertilizer packaging, ensuring the process remains uninterrupted. It also allows for short-term storage of mixed fertilizer before final weighing. For a 20 t/h BB fertilizer system, it need a 4*5m cache bin.

At the end of the 20 t/h BB fertilizer production line is the packaging system. The dual bucket packing scale is used to weigh, fill bags and sealing of mixed fertilizer in a large scale efficiently. In general, you need only to prepare 2 workers for the process.

Belt conveyors are key to transporting raw materials through each processing stage. Usually, a 20 t/h NPK granule mixing plant uses 3-5 sets of B600 conveyors with varying lengths (9m to 12m) strategically placed between equipment, ensuring smooth, continuous material flow. These conveyors are installed in sequence to minimize turning and space consumption.
